1 00:00:14,160 --> 00:00:18,310 hope you can all you me it's not that you know and peace to free 2 00:00:18,310 --> 00:00:20,920 to interrupted anytimes and questions 3 00:00:21,550 --> 00:00:25,690 so the topic is G T K propagation developers and 4 00:00:26,030 --> 00:00:26,360 i've 5 00:00:27,430 --> 00:00:30,050 but not us but it's an abstract that wasn't really clear on what i was 6 00:00:30,050 --> 00:00:34,580 going to do so well actually sit down to write prepared this talk i figured 7 00:00:34,580 --> 00:00:38,180 and i want to try and just show some examples of what's possible this project 8 00:00:38,180 --> 00:00:42,320 a K and i hope i can convey these examples that it's actually it's really 9 00:00:42,320 --> 00:00:47,180 easy not to build country style applications as we expect them to be that they 10 00:00:47,180 --> 00:00:48,220 had about that's 11 00:00:48,670 --> 00:00:52,290 nicely nice transitions and all that stuff that you see in blocks and rather than 12 00:00:52,290 --> 00:00:53,240 and these applications 13 00:00:53,980 --> 00:00:56,300 this is dedicated point and 14 00:00:56,890 --> 00:00:59,440 but most of the building block so that are in place and 15 00:01:00,730 --> 00:01:03,390 it doesn't take that much work to get something like that off the ground 16 00:01:04,040 --> 00:01:07,080 and i will show that in the series of examples 17 00:01:08,370 --> 00:01:10,010 then i had his nine steps 18 00:01:10,350 --> 00:01:13,670 yesterday's on going to show nine example sell forget so the 19 00:01:14,250 --> 00:01:17,870 and at the end i will have something that looks a bit like an application 20 00:01:17,870 --> 00:01:20,100 just really limited but that's something 21 00:01:20,940 --> 00:01:26,750 hopefully inspiring and i did not prepare a slide so this instead i decided i 22 00:01:26,750 --> 00:01:31,350 want this material to be available for the longer term so i will call as 23 00:01:31,350 --> 00:01:36,530 actually wanna but examples they all available in the did okay so three itself sometime 24 00:01:36,530 --> 00:01:37,070 last week 25 00:01:38,010 --> 00:01:42,210 and that extra rolled around it is it's all available in the G D K 26 00:01:42,210 --> 00:01:45,920 A P I documentation you have a tutorial section there and you check that right 27 00:01:46,800 --> 00:01:49,300 so you can look on it up online if you want 28 00:01:50,230 --> 00:01:51,990 it's available that solve 29 00:01:53,450 --> 00:01:53,970 last week 30 00:01:54,970 --> 00:01:58,760 and we'll see how well it actually works for talk it's an experiment so let 31 00:01:58,760 --> 00:02:01,110 me know if it doesn't work more than five to do something else 32 00:02:01,790 --> 00:02:05,710 so but before we step into the examples maybe it's were stepping back a little 33 00:02:05,710 --> 00:02:10,310 bit and ask what actually is an application we learned from that out yesterday 34 00:02:11,330 --> 00:02:14,140 how we things an application to look at the star trek future it's all the 35 00:02:14,140 --> 00:02:18,790 single bundle that you can just download and run it without installation it will be 36 00:02:18,790 --> 00:02:23,730 very cool but that's not quite where we are today so as of today applications 37 00:02:23,730 --> 00:02:26,760 that have a number of things that need to be spread around to five system 38 00:02:27,330 --> 00:02:31,800 and i just put up the list the of the things that are they obviously 39 00:02:31,800 --> 00:02:35,390 it's the application binary itself expected will use a bit 40 00:02:36,360 --> 00:02:40,130 then applications need to have a testify that's pretty from the established that the show 41 00:02:40,130 --> 00:02:45,020 can actually displayed nicely and it also needs and i can for that obviously 42 00:02:45,780 --> 00:02:50,130 and then every nontrivial applications will have some settings and for that we need a 43 00:02:50,130 --> 00:02:55,180 setting schema and then they might be just a miscellaneous other resources like you i 44 00:02:55,180 --> 00:02:56,680 files and whatnot 45 00:02:57,280 --> 00:03:00,580 which you would ordinarily also spatter on the five system 46 00:03:01,300 --> 00:03:05,750 but we actually have resources nowadays if you pay attention to the examples to see 47 00:03:05,750 --> 00:03:10,310 that we actually get to put all those other resources inside the binary itself so 48 00:03:10,310 --> 00:03:13,260 that's all already a pretty good step towards the 49 00:03:13,780 --> 00:03:15,400 single file application future 50 00:03:16,560 --> 00:03:17,590 that we want to get to 51 00:03:18,760 --> 00:03:23,370 and don't here i'll talk a little bit about all the stuff that i'm hoping 52 00:03:23,370 --> 00:03:24,690 to touch on the examples 53 00:03:25,200 --> 00:03:29,220 i'm not gonna we the whole list here you can see this stuff to go 54 00:03:29,220 --> 00:03:31,260 to so let's get to it 55 00:03:32,050 --> 00:03:34,300 in stockholm building up a vacation 56 00:03:35,270 --> 00:03:40,250 so the first thing to know about they don't want to use jic application here 57 00:03:40,250 --> 00:03:43,440 which is the application class that you can provide so that yes 58 00:03:44,750 --> 00:03:50,260 yes i know i just wanted to have the idea one line main functions like 59 00:03:50,260 --> 00:03:52,010 i was willing to like except that league 60 00:03:58,230 --> 00:04:00,520 so let's not go to too much on that the one thing to take away 61 00:04:00,520 --> 00:04:04,000 he is that the main function is really not ready action is it's just the 62 00:04:04,000 --> 00:04:09,570 one line that the really just creates an instance of obligation class and then we 63 00:04:09,570 --> 00:04:13,120 college application on it and to give at the command of parameters minutes it 64 00:04:13,800 --> 00:04:17,150 not much else to that's all the all the logic of application and all the 65 00:04:17,150 --> 00:04:20,980 ending of command line options and all that is happening in the application class 66 00:04:22,340 --> 00:04:28,280 so one and a little bit us a very trivial application classes we do some 67 00:04:28,280 --> 00:04:31,570 plastic application for that that's the intended way of using it 68 00:04:32,770 --> 00:04:37,670 and we used to the usual G object want to pay for that we don't 69 00:04:37,670 --> 00:04:39,550 really implement anything here yet 70 00:04:40,980 --> 00:04:45,190 just december entry points to applications this for instance if you just run the application 71 00:04:45,190 --> 00:04:50,740 all about them not giving it any arguments then we have an entry point it's 72 00:04:50,740 --> 00:04:52,290 called active at a 73 00:04:53,270 --> 00:04:56,930 which is what is called when you in then you just run it by itself 74 00:04:57,770 --> 00:05:02,210 and i have a kind of trivial application at implementation of that here which just 75 00:05:02,210 --> 00:05:04,420 creates a new window and then presented 76 00:05:05,510 --> 00:05:09,950 the entry point that i have implemented years opening files 77 00:05:10,610 --> 00:05:14,300 so if you run the application and give it file filenames on the command line 78 00:05:14,710 --> 00:05:19,440 well colour different into point it's called open and that gets an array of files 79 00:05:20,290 --> 00:05:23,380 and in this implementation here not much is happening we just 80 00:05:23,860 --> 00:05:27,110 again we created i would know and then we call this 81 00:05:27,550 --> 00:05:29,760 open function for each of the files and 82 00:05:30,400 --> 00:05:32,140 magic might happen the functional not 83 00:05:33,640 --> 00:05:38,250 and that's about it one thing to maybe briefly possible look at is 84 00:05:38,810 --> 00:05:41,220 that creating an application 85 00:05:41,730 --> 00:05:45,660 subclass you always want to have an application id that's kind important because that's really 86 00:05:46,210 --> 00:05:49,660 very central concept in the board of the application you really want to have an 87 00:05:49,660 --> 00:05:53,350 application id which is used as the last name and it seems just of ideally 88 00:05:53,350 --> 00:05:56,480 you system in for the best of file and all those things so we need 89 00:05:56,480 --> 00:05:58,540 a unique identifier for the implication 90 00:05:59,310 --> 00:06:00,450 and that's this idea here 91 00:06:03,860 --> 00:06:09,340 that's not a of this fairly trivial skeleton implementation is that just saw for that 92 00:06:09,340 --> 00:06:13,400 at some places i created windows 93 00:06:13,730 --> 00:06:18,360 and those and those are actually instances of this class example up a little 94 00:06:19,370 --> 00:06:22,620 which is a subclass of G T K application bundle and 95 00:06:23,300 --> 00:06:28,820 again this is an entirely empty imitation does nothing but than necessary scalable is a 96 00:06:28,820 --> 00:06:32,300 so it's a question like the last slide would be one line and it's this 97 00:06:32,300 --> 00:06:37,370 main what do you can tax you bind text domain is that handled for you 98 00:06:37,370 --> 00:06:40,460 and you have to shine directly or should and i mean as well i only 99 00:06:40,460 --> 00:06:43,340 glanced over that here but i guess you would have to do some setup work 100 00:06:43,340 --> 00:06:47,800 for that and okay so you do that automatically there's no magic that's just a 101 00:06:47,800 --> 00:06:49,480 matter don't know okay 102 00:06:50,430 --> 00:06:52,450 maybe my dad that if you to i don't know that 103 00:06:54,820 --> 00:06:58,920 so maybe things are changing that offer knowledgeable if you wanted internationalisation you have to 104 00:06:58,920 --> 00:06:59,550 set that up 105 00:07:00,790 --> 00:07:01,110 okay 106 00:07:02,310 --> 00:07:07,470 last thing that i have in this initial example is that we also one and 107 00:07:07,470 --> 00:07:10,480 i can attest of file up is the created some 108 00:07:11,080 --> 00:07:15,210 model like i can dare think the game for five minutes 109 00:07:15,600 --> 00:07:16,000 and 110 00:07:17,270 --> 00:07:21,930 the decibel it after five years also very couple of i just put an ad 111 00:07:21,930 --> 00:07:22,720 in the idea 112 00:07:23,760 --> 00:07:27,610 just to cheat a little bit because i'm running one able runs that location in 113 00:07:27,610 --> 00:07:31,870 a minute and i'm actually running it uninstalled so i have to actually catch to 114 00:07:31,870 --> 00:07:32,770 like being here 115 00:07:33,670 --> 00:07:34,620 to make that work 116 00:07:36,170 --> 00:07:38,230 and we actually switch to 117 00:07:39,010 --> 00:07:39,910 running his example 118 00:07:44,920 --> 00:07:46,170 should also take first 119 00:07:47,700 --> 00:07:51,190 this is inside the G T K so it is an examples directory and if 120 00:07:51,190 --> 00:07:51,790 you look and that 121 00:07:52,690 --> 00:07:56,500 this nine subdirectories which contain examples and i'm going to here 122 00:07:57,200 --> 00:07:59,340 and right now i'm stepping into the first one 123 00:08:02,700 --> 00:08:05,230 and it's already component are running it 124 00:08:06,800 --> 00:08:09,900 who this my educational it's not very exciting admittedly 125 00:08:10,440 --> 00:08:13,290 doesn't really contain anything it doesn't even will the title 126 00:08:13,550 --> 00:08:14,870 but 127 00:08:15,720 --> 00:08:18,350 notice that the channel already picks up the it has some five 128 00:08:19,280 --> 00:08:22,170 and find see i can we just because i she did a little bit and 129 00:08:22,170 --> 00:08:26,990 put the i can in the whole local share i can somewhere and up to 130 00:08:26,990 --> 00:08:29,850 justify there's also just that this works you 131 00:08:30,760 --> 00:08:34,620 and realised of course it's all these files and user share somewhere 132 00:08:35,130 --> 00:08:36,040 have it worked that way 133 00:08:37,790 --> 00:08:42,720 so it's not very impressive but admittedly we didn't write much good either and 134 00:08:43,360 --> 00:08:45,330 well there's not much to see this already 135 00:08:46,060 --> 00:08:50,370 it's a football geolocation which has a presence on the bus a single instance 136 00:08:51,650 --> 00:08:52,840 characteristics 137 00:08:53,370 --> 00:08:57,490 and it technically also kind of file so right now i just activated that are 138 00:08:57,490 --> 00:09:00,210 running it without arguments but it could give it a 139 00:09:01,960 --> 00:09:03,180 an argument like this 140 00:09:04,450 --> 00:09:07,880 well nothing else happens because we'd have implemented the open function yet but at least 141 00:09:07,880 --> 00:09:09,070 it accepts the adamant 142 00:09:10,090 --> 00:09:12,770 and things are set up for the next 143 00:09:15,250 --> 00:09:16,200 so step to is 144 00:09:17,480 --> 00:09:19,280 this winter was twenty so yes 145 00:09:22,180 --> 00:09:23,370 it's annoying isn't 146 00:09:24,320 --> 00:09:25,020 so they're not here 147 00:09:27,140 --> 00:09:28,000 and then for that 148 00:09:28,890 --> 00:09:31,300 okay so i'm next that is still 149 00:09:32,070 --> 00:09:36,300 get some content and the window so that we are using something that if you 150 00:09:36,300 --> 00:09:40,490 went to just on stock just before lunch you probably talked about ten that's 151 00:09:41,100 --> 00:09:42,320 maybe you didn't did you 152 00:09:43,090 --> 00:09:47,240 okay so we're using complex this is all just on that in the last year 153 00:09:47,240 --> 00:09:50,240 or two and it finally landed in G T K 154 00:09:50,860 --> 00:09:55,930 so what's attempted is likely you i follicles want to use to editing that's great 155 00:09:55,930 --> 00:09:56,880 operating late 156 00:09:57,660 --> 00:09:58,180 and 157 00:09:59,250 --> 00:10:01,020 just like that you can see the beginning of the file 158 00:10:02,130 --> 00:10:05,550 the my main difference between that and the directional you i find is that attempted 159 00:10:05,550 --> 00:10:09,610 actually define say it complex which is like a container with internal structure 160 00:10:10,070 --> 00:10:13,850 and you can use clay for populating that instead of having to manually writing in 161 00:10:13,850 --> 00:10:17,070 that function that that's G T K contain i had of this G T K 162 00:10:17,070 --> 00:10:22,990 box next out of that and handily really write a lot of code for populating 163 00:10:22,990 --> 00:10:26,650 your constructed your complex you are you can one adding like know which is really 164 00:10:27,320 --> 00:10:28,060 pretty nice 165 00:10:28,520 --> 00:10:31,800 and so he is our initial and that 166 00:10:32,980 --> 00:10:36,960 you can see we have a defining the example happen a class that i showed 167 00:10:36,960 --> 00:10:37,500 earlier 168 00:10:38,210 --> 00:10:41,880 maybe just pack a few things in the first of all we set some useful 169 00:10:41,880 --> 00:10:44,720 properties like to be no title and the people size 170 00:10:45,210 --> 00:10:48,360 maybe put in the box and they have the populate the box that i had 171 00:10:48,360 --> 00:10:49,120 about a stack 172 00:10:50,180 --> 00:10:54,130 you can stick and didn't and inside the had about we have a stack switching 173 00:10:55,040 --> 00:10:57,790 and i see these which it and actually in a minute 174 00:10:59,750 --> 00:11:03,320 but first able to stop briefly and show how we actually get to use this 175 00:11:03,320 --> 00:11:05,040 template so now we just click on the set 176 00:11:05,610 --> 00:11:06,420 you i file 177 00:11:07,190 --> 00:11:07,550 and 178 00:11:09,550 --> 00:11:13,750 to make use of it for actually defining application middle class we because a function 179 00:11:13,750 --> 00:11:17,330 called G T K widget class set template from resource 180 00:11:18,200 --> 00:11:19,920 which finds this templates 181 00:11:20,490 --> 00:11:21,120 to our 182 00:11:21,770 --> 00:11:22,680 or subclass 183 00:11:23,780 --> 00:11:27,590 and i talk about the results that in a minute bottom that's the first step 184 00:11:27,590 --> 00:11:32,220 the other step is that then we actually instantiate this class integrated application the know 185 00:11:32,830 --> 00:11:36,810 in the in a function for that we have to called you can project in 186 00:11:36,810 --> 00:11:42,090 the template actually use the template and populate our instance 187 00:11:43,020 --> 00:11:44,660 it's a two steps for using attempted 188 00:11:45,880 --> 00:11:49,310 and i touched on that earlier be using resources 189 00:11:50,470 --> 00:11:50,940 and 190 00:11:51,920 --> 00:11:56,100 that means that we actually take this window dot U I for the to the 191 00:11:56,100 --> 00:11:59,610 national italian fee turn it into a 192 00:12:00,530 --> 00:12:03,580 resource hundred happy then link into our education binary 193 00:12:04,530 --> 00:12:07,040 that's done using the tool called 194 00:12:07,650 --> 00:12:10,810 gina compile resources and do the proper resources takes 195 00:12:11,370 --> 00:12:16,610 it's input like we tell it what actually to compile into that resource bundle by 196 00:12:16,610 --> 00:12:18,760 but in this little excellence that up there 197 00:12:19,750 --> 00:12:22,680 and i'm not gonna get too much into it if you want to really look 198 00:12:22,680 --> 00:12:25,030 into that you can check out examples 199 00:12:25,600 --> 00:12:29,470 in the repository that's all hooked up with the makefile you can see actually running 200 00:12:30,480 --> 00:12:34,020 looking let me switch back to actually running this example now 201 00:12:35,030 --> 00:12:36,190 so we are stop to 202 00:12:38,400 --> 00:12:39,360 and i'm running it again 203 00:12:41,360 --> 00:12:41,730 but 204 00:12:42,630 --> 00:12:45,530 as you can see the windows not entirely empty at this point you have 205 00:12:46,050 --> 00:12:49,820 obviously we have the window title and if you if you look at the top 206 00:12:49,820 --> 00:12:53,760 of them and you can kind of see the and you had about their which 207 00:12:54,440 --> 00:12:58,030 it's not really prominent of the that's gonna get populated in the next steps 208 00:12:58,890 --> 00:13:01,720 well no this is just basis for the work 209 00:13:07,450 --> 00:13:08,550 okay so that's me is 210 00:13:09,850 --> 00:13:15,350 we want to actually populate the speculated that we put in place an ultimate upon 211 00:13:15,350 --> 00:13:17,740 that out and we want to 212 00:13:18,230 --> 00:13:21,500 i to act what you know if you can are already passed financial the command 213 00:13:21,500 --> 00:13:25,010 line so the next have a step we actually want to open these files and 214 00:13:25,010 --> 00:13:25,770 children 215 00:13:26,810 --> 00:13:28,150 for that 216 00:13:30,270 --> 00:13:33,290 because if you know features that want to mention 217 00:13:34,920 --> 00:13:37,770 all example brno class now case a private start 218 00:13:40,230 --> 00:13:44,380 you can see to find out there that contains just one on i'm not currently 219 00:13:44,800 --> 00:13:46,290 this stack pointer there 220 00:13:47,970 --> 00:13:51,530 and there's a new way actually just change recently you the way it used to 221 00:13:51,530 --> 00:13:53,950 be for private starts that you use to call 222 00:13:54,700 --> 00:14:00,020 G type class at try that in your class in a function and we turned 223 00:14:00,020 --> 00:14:04,210 that around to cycle and we actually made that more declarative so now the new 224 00:14:04,210 --> 00:14:08,570 way of doing this is that you use G define typhus private and that that's 225 00:14:08,570 --> 00:14:09,790 automatically on seems 226 00:14:10,290 --> 00:14:13,470 we don't have to do anything anymore in your class function for this 227 00:14:14,410 --> 00:14:16,970 and it is that you can do something else in your class in a function 228 00:14:16,970 --> 00:14:17,560 which is 229 00:14:18,090 --> 00:14:19,130 well you can use 230 00:14:20,500 --> 00:14:24,000 this somewhat magic thing here called G T K widget last 231 00:14:24,320 --> 00:14:27,460 find template right private that's quite a most well i think that's the content of 232 00:14:27,460 --> 00:14:29,280 a long as function name and G T K 233 00:14:32,120 --> 00:14:35,740 i couldn't really how it need to be that long to fit all the naming 234 00:14:35,740 --> 00:14:38,010 patterns and everything else so what does this do 235 00:14:39,300 --> 00:14:43,380 just for the should things behind the scene so we give it the example happened 236 00:14:43,380 --> 00:14:44,100 or name 237 00:14:45,110 --> 00:14:48,310 and we give it a name of variables that there and 238 00:14:48,810 --> 00:14:53,110 what's happening behind the scene is that this instructs you to create a 239 00:14:54,260 --> 00:14:58,420 because to use the private various function it knows that it actually is supposed to 240 00:14:58,420 --> 00:15:02,810 look in the private struck that's also associated press example happen all so example up 241 00:15:02,810 --> 00:15:03,410 in the private 242 00:15:04,250 --> 00:15:04,650 and 243 00:15:05,390 --> 00:15:07,190 should look for this stack member in it 244 00:15:08,100 --> 00:15:10,570 and it showed populate definitely 245 00:15:11,260 --> 00:15:13,880 that which it from the template that escorts that 246 00:15:14,880 --> 00:15:17,930 so this is one of the magic not at actual this that when we get 247 00:15:17,930 --> 00:15:20,810 to a instance and it function we can rely on the fact that the 248 00:15:21,550 --> 00:15:25,110 the staff member in our private structures is pointing to the better that we want 249 00:15:25,110 --> 00:15:25,740 to point to 250 00:15:26,310 --> 00:15:29,320 so there's not a lot of hassle manually look and also 251 00:15:33,130 --> 00:15:34,780 i don't know that's a question from under 252 00:15:38,770 --> 00:15:42,670 okay so this was just preparatory work for actually 253 00:15:44,390 --> 00:15:47,760 doing some actual logic here i'm not gonna explain this in detail 254 00:15:48,260 --> 00:15:53,190 this is the code to create a store dwindle great attacks to inside it and 255 00:15:53,190 --> 00:15:55,820 open the file that was passed as an argument 256 00:15:56,180 --> 00:15:58,800 and populate the text to with the contents of that file 257 00:15:59,470 --> 00:16:03,760 one thing that's worth pointing out us some venom at all this a line the 258 00:16:03,760 --> 00:16:05,700 record it a stack at titled 259 00:16:06,140 --> 00:16:07,670 that is very actually at the 260 00:16:08,440 --> 00:16:12,300 this more brno S A H in our state so to speak 261 00:16:12,980 --> 00:16:13,380 and 262 00:16:14,010 --> 00:16:17,690 we give it very unique identifier for that we just use the basin of the 263 00:16:17,690 --> 00:16:20,830 file and then there's another argument which is 264 00:16:21,620 --> 00:16:24,860 did a display title to actually show in the you know i will see that 265 00:16:25,700 --> 00:16:27,140 the be obvious one so run it 266 00:16:29,440 --> 00:16:34,180 and the other one thing i want to say about that is that the display 267 00:16:34,180 --> 00:16:37,350 type is obviously going to be displayed but this text which i would just the 268 00:16:37,350 --> 00:16:38,560 rolls of caps 269 00:16:39,120 --> 00:16:41,640 but we don't have to touch this text which at all you because 270 00:16:42,190 --> 00:16:46,110 this text which are just getting all this data needs to know how many types 271 00:16:46,110 --> 00:16:50,340 display able to show and then by looking at the at the stack that is 272 00:16:50,340 --> 00:16:51,180 associated with 273 00:16:58,960 --> 00:16:59,820 so the problem 274 00:17:01,770 --> 00:17:03,900 so i'm switching back to running as well 275 00:17:06,460 --> 00:17:09,700 well that's magic now we actually have contended it looks like a real application of 276 00:17:09,700 --> 00:17:13,170 so let me make is a little bit and actually given files 277 00:17:27,490 --> 00:17:30,430 i don't know that's a question for the design as i think i mean i 278 00:17:30,430 --> 00:17:31,820 think about available for this case 279 00:17:32,760 --> 00:17:33,150 and 280 00:17:34,720 --> 00:17:38,850 i would i'm sure the designers would do time we often find something wrong about 281 00:17:39,560 --> 00:17:40,990 it works so 282 00:17:42,500 --> 00:17:46,220 good things to say it is that you see this text which are now that's 283 00:17:46,220 --> 00:17:48,090 the like the two buttons updated 284 00:17:48,570 --> 00:17:50,820 those get created but it's text which are 285 00:17:51,450 --> 00:17:52,830 and you know the 286 00:17:53,920 --> 00:17:56,430 the content of the file at U C obviously council 287 00:17:57,160 --> 00:17:59,670 from the function i just showed you and we can 288 00:18:00,920 --> 00:18:03,900 actually switch between them and it works so that that's you can stack and you 289 00:18:03,900 --> 00:18:04,830 can stick switcher 290 00:18:05,420 --> 00:18:05,940 connection 291 00:18:13,790 --> 00:18:17,790 i just keep moving on is this questions feel free to interrupt me at any 292 00:18:17,790 --> 00:18:18,060 time 293 00:18:19,020 --> 00:18:22,580 next this we want to resolve a little more that an application menu i don't 294 00:18:22,580 --> 00:18:25,750 need to say too much evolved modification men us and how it works 295 00:18:26,380 --> 00:18:29,300 well dive right into how you do this 296 00:18:30,880 --> 00:18:33,900 and also get specified by educator that you iphone 297 00:18:34,860 --> 00:18:36,380 like this one here 298 00:18:37,300 --> 00:18:41,450 and i don't think i should say too much and details about the syntax you 299 00:18:41,450 --> 00:18:46,420 can see that we actually created menu element which is a menu not surprisingly and 300 00:18:46,420 --> 00:18:47,900 they can be sections in there 301 00:18:48,490 --> 00:18:50,520 and items and the items have 302 00:18:51,690 --> 00:18:54,590 a couple of at a good see a we set a label which is what's 303 00:18:54,590 --> 00:18:56,820 gonna going to shop in the U I 304 00:18:57,380 --> 00:18:59,690 and then we have an action for each item 305 00:19:00,250 --> 00:19:03,360 which is what's going to get activated and you have to check on that menu 306 00:19:03,360 --> 00:19:03,570 item 307 00:19:05,720 --> 00:19:11,660 and actually used is you i for an obligation we need to call G T 308 00:19:11,660 --> 00:19:13,460 K application setup menu 309 00:19:14,990 --> 00:19:18,290 and a good place to do that is in the startup before 310 00:19:19,030 --> 00:19:20,620 of your energy application 311 00:19:21,250 --> 00:19:24,620 i mentioned earlier that you application as a number of different entry points like it 312 00:19:24,620 --> 00:19:28,710 has an active right does it open or you could activated by directly calling in 313 00:19:28,710 --> 00:19:29,180 action 314 00:19:29,990 --> 00:19:35,960 and how you activated how you started there's always a startup different that it gets 315 00:19:35,960 --> 00:19:36,790 caught no matter what 316 00:19:37,550 --> 00:19:40,490 so that's a good place to do things that you want to happen in all 317 00:19:40,490 --> 00:19:41,220 the cases 318 00:19:41,840 --> 00:19:43,580 because if you have to actually 319 00:19:44,260 --> 00:19:45,760 get a lot 320 00:19:46,210 --> 00:19:48,010 you are funded i just so 321 00:19:48,470 --> 00:19:49,060 and then we 322 00:19:50,310 --> 00:19:51,640 well you get the menu model 323 00:19:52,010 --> 00:19:56,650 that the data constructed format and we called you get jic application setup menu 324 00:19:57,680 --> 00:20:01,810 which does all the work behind the scenes just this puts us stuff on the 325 00:20:01,810 --> 00:20:04,160 bus on the session but also the show picks it up from there so that's 326 00:20:04,160 --> 00:20:07,320 a lot of things that are happening behind the scenes of that's right 327 00:20:12,070 --> 00:20:16,320 right i did not really get into the difference between finer primary and secondary instance 328 00:20:16,320 --> 00:20:21,600 but you're so right points out that G application as this concept of single instance 329 00:20:21,600 --> 00:20:27,050 which are briefly mentioned earlier and that means there's a primary instance which is actually 330 00:20:27,050 --> 00:20:32,140 fourty flash running application and if you start again on the command line it's not 331 00:20:32,140 --> 00:20:34,070 gonna open set second binary but just 332 00:20:34,540 --> 00:20:35,940 talk to the primary instance 333 00:20:36,730 --> 00:20:40,540 and the startup function i said it gets run no matter what it only gets 334 00:20:40,540 --> 00:20:43,810 run in the province but if you're if you're starting at or second time and 335 00:20:43,810 --> 00:20:46,250 doesn't actually launch something them started with not 336 00:20:51,050 --> 00:20:52,720 okay that's a fair point 337 00:20:54,860 --> 00:20:58,400 going back to this i said earlier in a financial to you have a if 338 00:20:58,400 --> 00:21:01,640 you to be mention applications like each item as an associated action 339 00:21:02,420 --> 00:21:05,460 and so we need to somehow bring these actions into 340 00:21:05,970 --> 00:21:10,090 into being and that's what what's happening actually four lines up here 341 00:21:10,410 --> 00:21:14,360 we call a function called G action map at actually entries 342 00:21:15,190 --> 00:21:15,670 which is 343 00:21:17,270 --> 00:21:20,310 also a lot of work that's happening by the scenes that school of a little 344 00:21:20,310 --> 00:21:20,690 bit 345 00:21:21,040 --> 00:21:24,760 you can actually see the add entries irate if you pass in there 346 00:21:25,320 --> 00:21:28,740 this looks very similar to what we what we have and how to indicate for 347 00:21:28,740 --> 00:21:32,460 the longest time which is a G T K action entry every 348 00:21:33,100 --> 00:21:38,940 and this is just basically the same kind of idea translated into G action sort 349 00:21:38,940 --> 00:21:39,860 of detection 350 00:21:41,080 --> 00:21:44,960 so we are creating to actions one is as the name preferences minus on this 351 00:21:44,960 --> 00:21:45,670 and it could 352 00:21:46,190 --> 00:21:48,570 just a student to do that you saw the U I five before 353 00:21:49,370 --> 00:21:54,670 and we have you be also specify the activate callbacks you like could activated it's 354 00:21:54,670 --> 00:21:57,950 called in the collection is activated preferences activated escort 355 00:21:58,890 --> 00:22:01,710 when preferences you preference actions activated 356 00:22:03,180 --> 00:22:04,240 that's actually try that out 357 00:22:07,660 --> 00:22:08,900 so not to step for 358 00:22:12,740 --> 00:22:14,000 that you have to have an 359 00:22:14,810 --> 00:22:19,060 vision and you know yes it's there so the shell has successfully picked up 360 00:22:20,170 --> 00:22:21,940 menu the other people on the bus 361 00:22:22,710 --> 00:22:26,540 and that S which it shows of the preferences and could menu item 362 00:22:27,400 --> 00:22:29,210 no one click on preferences 363 00:22:30,640 --> 00:22:34,410 nothing happens that's because the preferences activity function that i just is percent these of 364 00:22:34,410 --> 00:22:35,140 us nothing 365 00:22:36,640 --> 00:22:39,220 exciting is going on but it is fully functional 366 00:22:40,900 --> 00:22:43,800 just works and a little bit want to show that 367 00:22:44,490 --> 00:22:47,670 you may not more may not what is it but for the for the could 368 00:22:47,670 --> 00:22:53,740 i don't actually specified a keyboard accelerator people talk out in the U I for 369 00:22:53,740 --> 00:22:55,100 the expected one controlled you 370 00:22:55,770 --> 00:22:57,020 and when i had control to here 371 00:22:57,630 --> 00:23:00,270 also works or that is already hooked up 372 00:23:01,490 --> 00:23:05,080 and the next that will be to make the preferences menu item actually something 373 00:23:06,890 --> 00:23:08,920 well that i'm moving on to the next step 374 00:23:10,550 --> 00:23:11,090 which is 375 00:23:12,090 --> 00:23:14,110 soon so how preferences work 376 00:23:14,920 --> 00:23:15,380 and 377 00:23:17,580 --> 00:23:21,490 we want our preferences obviously to be remembered from one run of the application for 378 00:23:21,490 --> 00:23:24,730 the next are we gonna use G settings to number them 379 00:23:25,920 --> 00:23:30,500 and for using G settings the first step is always to that you need a 380 00:23:30,500 --> 00:23:31,720 schema for a settings 381 00:23:32,510 --> 00:23:34,780 which is another type of X M L file actually here 382 00:23:35,450 --> 00:23:38,980 is fairly minimal scheme are just system to settings and it the one is 383 00:23:39,780 --> 00:23:41,490 a font the unless a transition time 384 00:23:45,550 --> 00:23:49,610 there's some magic that you need to do some magic intent incantations that you need 385 00:23:49,610 --> 00:23:53,270 to do to make it make use of the scheme or you have to compile 386 00:23:53,270 --> 00:23:54,600 it but you have to like 387 00:23:55,120 --> 00:24:00,320 installed icexml from the right location and then you call gina comply schemas to 388 00:24:01,250 --> 00:24:03,990 it's gotta be have some autoconf 389 00:24:04,650 --> 00:24:06,030 macros to make that 390 00:24:06,460 --> 00:24:08,300 the little easier if you're using all the tools 391 00:24:09,160 --> 00:24:11,690 so i'm not gonna dive into the details of how to do that let's just 392 00:24:11,690 --> 00:24:12,110 assume 393 00:24:12,910 --> 00:24:14,620 that we can figure that out 394 00:24:15,890 --> 00:24:19,080 and so now we have a disk in that case 395 00:24:19,670 --> 00:24:23,570 which means you can actually now use our settings and for that 396 00:24:24,960 --> 00:24:28,730 we need to quality settings new to obtain an instance of our settings 397 00:24:29,360 --> 00:24:29,870 object 398 00:24:31,130 --> 00:24:31,610 and 399 00:24:33,100 --> 00:24:36,910 the next thing we do is we use a very convenient functionality of T settings 400 00:24:36,910 --> 00:24:38,060 which is finding 401 00:24:38,500 --> 00:24:43,270 so we have this settings here actually earlier which is about the other which was 402 00:24:43,270 --> 00:24:44,040 called transition 403 00:24:44,960 --> 00:24:46,750 and we just find that too 404 00:24:47,090 --> 00:24:49,320 remember pressed accuracy 405 00:24:49,810 --> 00:24:54,540 it's a pointer that points to the do you can stack which is that we 406 00:24:54,540 --> 00:24:56,730 have in our window somewhere 407 00:24:57,480 --> 00:25:01,770 and the do you can stack it's a property that's called transition type 408 00:25:02,470 --> 00:25:04,360 and i would just by deciding to the 409 00:25:04,750 --> 00:25:05,960 to the property 410 00:25:06,500 --> 00:25:10,500 and that's all we need to do to make the reject reactor the changes of 411 00:25:10,500 --> 00:25:10,970 the setting 412 00:25:18,740 --> 00:25:21,710 there's some educated and i'm not gonna get into right now 413 00:25:22,090 --> 00:25:23,260 it's even better than 414 00:25:23,360 --> 00:25:24,270 then i'm telling 415 00:25:24,710 --> 00:25:25,200 so let's 416 00:25:30,360 --> 00:25:32,150 let's see if i can actually because 417 00:25:33,890 --> 00:25:37,250 so remember we don't have a preference dialogue get that we have hooked up to 418 00:25:37,250 --> 00:25:38,270 setting service 419 00:25:38,830 --> 00:25:41,080 going to see and if i can actually 420 00:25:42,870 --> 00:25:45,310 prove to you that if i don't change the settings 421 00:25:46,170 --> 00:25:48,670 on the command line using the G settings commitment to 422 00:25:51,790 --> 00:25:52,700 i hope that something is 423 00:25:53,240 --> 00:25:56,360 as i mean i was gonna less impressive that wanted because the window was hidden 424 00:25:56,360 --> 00:25:57,410 but you can see that the 425 00:25:58,130 --> 00:26:02,750 the application actually picked up my phone so strange before was one space to open 426 00:26:02,750 --> 00:26:03,590 autumn especially 427 00:26:05,250 --> 00:26:08,530 but obviously using the command line for these kind of changes it's not ideal so 428 00:26:08,530 --> 00:26:09,120 we want to 429 00:26:09,970 --> 00:26:13,980 a preference dialogue so that that's move on and constructive 430 00:26:17,570 --> 00:26:21,500 obviously be we use all the same things that we've already used to be again 431 00:26:21,500 --> 00:26:24,340 right attempted five for this dialogue this time it's a 432 00:26:25,980 --> 00:26:28,260 it's a subclass of you could dialogue can see appear 433 00:26:29,060 --> 00:26:32,760 and i'm not gonna go to listen detail but you can see that we populated 434 00:26:32,760 --> 00:26:33,370 that they 435 00:26:34,210 --> 00:26:38,270 some labels and the data from that they're gonna use for the phone probably obviously 436 00:26:39,320 --> 00:26:40,820 and the little further down 437 00:26:42,570 --> 00:26:46,730 is a combo box that using for the this transition property which is three possible 438 00:26:46,730 --> 00:26:47,310 values 439 00:26:48,020 --> 00:26:51,490 and i'm specifying them right in the in the template 440 00:26:56,130 --> 00:26:56,620 and then 441 00:26:59,340 --> 00:27:02,330 you obviously a great a subclass of ticket dialogue for this 442 00:27:02,740 --> 00:27:03,800 using the standard 443 00:27:04,180 --> 00:27:07,600 so there's all the same one i played and i showed you for our occasional 444 00:27:08,710 --> 00:27:10,870 you find type of private that business 445 00:27:11,880 --> 00:27:17,730 and we do the same tended finding that we did for vacation and when this 446 00:27:17,730 --> 00:27:20,350 time you do it for a preference dialogue 447 00:27:21,010 --> 00:27:23,580 we again obtain an instance of our settings you 448 00:27:25,090 --> 00:27:25,930 percent X 449 00:27:27,070 --> 00:27:31,320 and again we use the settings finding functionality combine 450 00:27:31,900 --> 00:27:37,050 or settings this time to bite into the controls we have in the dialogue actually 451 00:27:37,050 --> 00:27:37,710 the changing 452 00:27:38,280 --> 00:27:40,530 so for the for the font setting the use the 453 00:27:41,240 --> 00:27:42,720 the functional 454 00:27:43,910 --> 00:27:46,970 and for the position settings use this combo box 455 00:27:47,350 --> 00:27:50,960 i didn't actually pointed out that the name of that budget in the time that 456 00:27:50,960 --> 00:27:51,840 five was position 457 00:27:54,330 --> 00:27:54,870 and 458 00:27:56,900 --> 00:27:58,790 there's a lot more part of it here 459 00:27:59,320 --> 00:28:00,340 on think we still have to do is 460 00:28:01,890 --> 00:28:05,980 we created this preferences activated callback for the action but it was empty so we 461 00:28:05,980 --> 00:28:07,490 know need to go back to it and 462 00:28:08,080 --> 00:28:13,460 make it actually created you instance of a preference dialogue and present that 463 00:28:16,500 --> 00:28:16,900 and 464 00:28:17,870 --> 00:28:19,500 so let's go back and see how that looks 465 00:28:30,430 --> 00:28:35,150 you can see of all font settings change from last one got remembered across to 466 00:28:35,150 --> 00:28:35,700 be stuff 467 00:28:36,370 --> 00:28:36,850 and 468 00:28:37,520 --> 00:28:42,060 no tricking preferences again and a test our preference that'll and it has the things 469 00:28:42,060 --> 00:28:45,810 that i pointed out earlier in the that so there's a one choose a 470 00:28:46,730 --> 00:28:49,220 chose the value that we just sat in the on the command line 471 00:28:50,010 --> 00:28:52,340 and that's the combo box for the transition 472 00:28:53,280 --> 00:28:56,690 just gonna briefly pause and show what it actually does 473 00:28:57,470 --> 00:28:58,310 change the slide 474 00:28:59,950 --> 00:29:02,140 and if i know change taps here 475 00:29:03,150 --> 00:29:06,050 actually any mates so this is a new feature indicates that 476 00:29:06,760 --> 00:29:09,110 as opposed to the old do you can notebook 477 00:29:09,740 --> 00:29:13,380 you can actually do nice animated transitions here the other one that i have it 478 00:29:13,380 --> 00:29:16,410 here in the preference dialogue i'm gonna show that as well as the cross fade 479 00:29:18,470 --> 00:29:19,850 so for change to that then 480 00:29:20,830 --> 00:29:22,660 you can kind of see the cross fade happening here 481 00:29:23,740 --> 00:29:27,980 so that's a nice new feature of you can stack which is made possible by 482 00:29:27,980 --> 00:29:34,060 all the frame based drawing like that owned it the last year 483 00:29:35,890 --> 00:29:37,110 okay well known 484 00:29:39,690 --> 00:29:43,780 this application starting to look like an application that's fairly minimal so will add a 485 00:29:43,780 --> 00:29:45,650 few more bits of functionality here 486 00:29:46,170 --> 00:29:50,710 the next that is very common and don't see application research that's obviously very central 487 00:29:50,710 --> 00:29:53,650 so i want to show how to make be 488 00:29:54,390 --> 00:29:58,590 research entry here that looks somewhat similar to what we have another one applications 489 00:29:59,790 --> 00:30:04,540 product we the use do you can search entry which is just a subclass of 490 00:30:04,540 --> 00:30:07,540 do you can feel it has a bit of extra functionality 491 00:30:08,450 --> 00:30:11,870 to make a certain like basically a button and it has see extra signal that 492 00:30:11,870 --> 00:30:15,830 kind of patches the changes things like that and then we used to do concerts 493 00:30:15,830 --> 00:30:17,120 but i would just and you a budget 494 00:30:18,150 --> 00:30:19,030 which lets you 495 00:30:20,190 --> 00:30:24,600 place such country and maybe some other divided you might need and content in relation 496 00:30:24,600 --> 00:30:24,960 to that 497 00:30:25,540 --> 00:30:26,750 in inside a 498 00:30:27,780 --> 00:30:29,700 toolbar model stick and slide in from the top 499 00:30:31,590 --> 00:30:34,010 let's see how we actually use those 500 00:30:35,530 --> 00:30:37,680 so they go back to our 501 00:30:38,370 --> 00:30:39,970 have that for application than or 502 00:30:40,540 --> 00:30:41,650 and the and if you extra things 503 00:30:44,400 --> 00:30:47,870 right we had a probable so they had a bar 504 00:30:48,500 --> 00:30:50,980 the be much easier to see that men i run the application and i'm just 505 00:30:50,980 --> 00:30:52,380 pointing out how this looks and they 506 00:30:52,950 --> 00:30:53,410 covered 507 00:30:56,010 --> 00:30:56,630 and 508 00:30:58,170 --> 00:30:59,050 no further down 509 00:31:00,570 --> 00:31:03,440 between the had about the stack you know put a search by 510 00:31:04,260 --> 00:31:05,890 the search but contains a search entry 511 00:31:07,350 --> 00:31:07,870 and 512 00:31:08,420 --> 00:31:09,670 what we also do here is 513 00:31:10,780 --> 00:31:14,650 we hook up this segment of for the search changed signal of the searching for 514 00:31:14,650 --> 00:31:17,500 you might you know that have that right so we don't have too many legal 515 00:31:17,500 --> 00:31:19,060 ninety six not connect to know 516 00:31:19,790 --> 00:31:21,710 so once again this reduces 517 00:31:22,480 --> 00:31:25,200 the amount of menu cool to have to be produced 518 00:31:26,420 --> 00:31:31,120 and obviously implementing search actually takes quite a bit of work i'm not gonna go 519 00:31:31,120 --> 00:31:33,700 to that in detail here but i just wanted to 520 00:31:34,300 --> 00:31:38,170 if you show that there see the main did to be for this work us 521 00:31:38,170 --> 00:31:42,770 having a second like he has touched exchange which gets called 522 00:31:43,280 --> 00:31:46,020 whenever you talk a new character in your surgery 523 00:31:47,040 --> 00:31:50,960 and then we would do magic was text you just to find the first match 524 00:31:50,960 --> 00:31:52,160 for that you know text 525 00:31:52,960 --> 00:31:53,370 and 526 00:31:54,070 --> 00:31:54,880 one vector 527 00:31:56,630 --> 00:31:57,800 like a couple again 528 00:32:02,180 --> 00:32:04,460 so it is well you can see the 529 00:32:05,400 --> 00:32:07,510 there's of like on is that all the button that i mentioned 530 00:32:08,580 --> 00:32:09,380 if i click that's 531 00:32:12,140 --> 00:32:14,140 so sparse lights in the such entry 532 00:32:15,570 --> 00:32:17,430 and i can type something like 533 00:32:21,410 --> 00:32:22,000 so just 534 00:32:22,540 --> 00:32:23,350 that's kinda need 535 00:32:26,960 --> 00:32:28,320 escape i think 536 00:32:29,410 --> 00:32:29,890 okay 537 00:32:31,580 --> 00:32:32,350 so 538 00:32:33,310 --> 00:32:34,720 that's already pretty good 539 00:32:36,320 --> 00:32:39,660 but you can at the present a little more functionality you before but i'm not 540 00:32:39,660 --> 00:32:40,450 so 541 00:32:41,640 --> 00:32:44,510 think it's a step eight of nine so i might actually gets too much steps 542 00:32:44,510 --> 00:32:45,400 supposed to learn that 543 00:32:47,900 --> 00:32:48,620 sidebar 544 00:32:50,510 --> 00:32:55,210 i really have to like wracked my brain to come up is some example that 545 00:32:55,210 --> 00:32:58,200 lets me put in as many of the new but just as possible so i 546 00:32:58,730 --> 00:33:03,110 cannot this let me let me know that that's totally ridiculous but at least it 547 00:33:03,110 --> 00:33:07,220 gets the don't drop down definitional do you can menu button did you can reveal 548 00:33:07,220 --> 00:33:08,790 and you can just box set 549 00:33:10,410 --> 00:33:11,510 so once again we 550 00:33:12,540 --> 00:33:13,890 go back into our tempted 551 00:33:14,740 --> 00:33:17,560 and we are just sort you that we added top to bottom 552 00:33:18,610 --> 00:33:22,220 we know at a menu button next to that that's down here you can menu 553 00:33:22,220 --> 00:33:22,470 button 554 00:33:26,010 --> 00:33:28,280 and then going for the down 555 00:33:28,720 --> 00:33:30,700 and maybe used to have the G T K stack 556 00:33:31,330 --> 00:33:31,990 we know 557 00:33:32,770 --> 00:33:35,220 wrap that inside you get box and 558 00:33:35,680 --> 00:33:36,450 put a 559 00:33:37,070 --> 00:33:37,840 a little extra 560 00:33:38,590 --> 00:33:41,840 before it is actually i was audible so we put something left 561 00:33:42,250 --> 00:33:45,920 which is a G T K with you know that contains a list box in 562 00:33:45,920 --> 00:33:46,770 the school window 563 00:33:49,130 --> 00:33:49,690 and 564 00:33:52,830 --> 00:33:55,500 it's a little more xml here to show 565 00:33:56,020 --> 00:33:59,110 i said that i put a menu button there i didn't actually tell you where 566 00:33:59,110 --> 00:34:01,430 the menus coming from that's yet another 567 00:34:02,020 --> 00:34:03,970 the U I for that actually here 568 00:34:04,510 --> 00:34:09,320 which is really virtually identical to the syntax of the one that i showed you 569 00:34:09,320 --> 00:34:10,760 polyak menu it's just another 570 00:34:11,340 --> 00:34:13,770 you i five to be find a gym anymore 571 00:34:14,790 --> 00:34:17,730 in this case i just put a single item in there right now 572 00:34:18,270 --> 00:34:22,330 just a label words and they know the action here words 573 00:34:23,640 --> 00:34:26,500 and obviously i need to tell you where that actually comes from 574 00:34:27,250 --> 00:34:31,140 so we go back to this is actually to go back you can 575 00:34:32,480 --> 00:34:36,020 i so i called action show works but actually the U I five says when 576 00:34:36,020 --> 00:34:37,180 dot show words 577 00:34:38,010 --> 00:34:42,740 the window hottest this goebbels the action so the actions we saw before for the 578 00:34:42,740 --> 00:34:47,070 application manoeuvre applications goal actions which we defined in 579 00:34:47,690 --> 00:34:49,920 in the startup function of the application 580 00:34:50,670 --> 00:34:53,570 but there can also be we know school actions 581 00:34:53,980 --> 00:34:57,840 and the can i mention here is that you refer to those by putting went 582 00:34:57,840 --> 00:34:59,680 off as the prefix the name 583 00:35:00,640 --> 00:35:05,130 and obviously in brno school action should not be defined in the G application startup 584 00:35:05,130 --> 00:35:09,620 function but it should be specific to the rental so we at that action in 585 00:35:09,620 --> 00:35:12,450 the in the function of our example than a class 586 00:35:13,470 --> 00:35:17,240 and the last three lines that actually but it happens 587 00:35:17,940 --> 00:35:21,320 in this case we use a settings actually 588 00:35:22,000 --> 00:35:26,550 which is a neat little this integrate to take one of audio settings 589 00:35:27,850 --> 00:35:33,020 in this case it's setting called sure words and just wrap actually and actually wanted 590 00:35:33,990 --> 00:35:34,610 and 591 00:35:35,960 --> 00:35:39,500 activating the action will have that we change the value of the setting 592 00:35:40,170 --> 00:35:43,680 this case the setting this is leon and 593 00:35:45,100 --> 00:35:48,340 the settings action who just probably and every time you activated 594 00:35:49,350 --> 00:35:53,260 that's a very convenient way to make settings available to the you live in the 595 00:35:53,260 --> 00:35:54,020 form of actions 596 00:35:56,370 --> 00:35:59,590 and but that i'm switching back to show you know that looks 597 00:36:06,220 --> 00:36:06,740 okay so 598 00:36:08,360 --> 00:36:10,600 next a lot of the button up there 599 00:36:10,920 --> 00:36:12,100 is to get something you know 600 00:36:13,450 --> 00:36:13,920 menu button 601 00:36:15,150 --> 00:36:15,730 click connect 602 00:36:16,610 --> 00:36:17,840 is the menu item that i just 603 00:36:18,530 --> 00:36:19,280 mystified 604 00:36:19,780 --> 00:36:21,320 and if i actually 605 00:36:21,650 --> 00:36:22,290 product 606 00:36:23,790 --> 00:36:27,590 decide partials up and you saw that it actually slides and that's what the really 607 00:36:27,590 --> 00:36:29,770 knows doing it cannot that's the animated 608 00:36:30,190 --> 00:36:31,170 reveal 609 00:36:31,640 --> 00:36:34,460 and inside they really lazy 610 00:36:35,030 --> 00:36:38,590 in this box here this block so i could can spend an entire talked us 611 00:36:38,590 --> 00:36:42,240 talking about do you can this box and what that's about it doesn't do but 612 00:36:42,240 --> 00:36:44,740 it is essentially it's just a container that is 613 00:36:45,410 --> 00:36:48,100 it's meant to contain lots of digits and it has 614 00:36:48,620 --> 00:36:53,320 functionality that you normally associate with the but that review like it can filter can 615 00:36:53,320 --> 00:36:55,420 consult the items that are contained in it 616 00:36:56,450 --> 00:37:00,970 but the to the defining difference between this and the triggers that 617 00:37:01,530 --> 00:37:05,480 it shows actually is that which it it's not a seven day which is kind 618 00:37:05,480 --> 00:37:08,600 of a different layout model so this is nice if you want to have a 619 00:37:08,600 --> 00:37:09,070 list 620 00:37:09,610 --> 00:37:13,760 but you want to have actual july and it's not necessarily just data-driven 621 00:37:14,730 --> 00:37:15,680 giant data is 622 00:37:16,220 --> 00:37:18,850 and since i have to come up to something for this example adjust 623 00:37:19,640 --> 00:37:23,900 created buttons one button for each button my text and if i click on one 624 00:37:23,900 --> 00:37:24,690 of those buttons 625 00:37:25,860 --> 00:37:27,700 research again so this december 626 00:37:28,840 --> 00:37:30,280 make this example but meaningful 627 00:37:37,470 --> 00:37:38,180 right 628 00:37:40,020 --> 00:37:42,350 and i just saw the movie to hide itself again 629 00:37:43,150 --> 00:37:43,880 so we don't 630 00:37:46,110 --> 00:37:47,560 almost and this is the last step 631 00:37:48,040 --> 00:37:51,990 but i've been about them of this like first it had only it's that's actually 632 00:37:51,990 --> 00:37:56,970 and then ryan came back to me and said okay just reason like probably actions 633 00:37:57,600 --> 00:38:01,160 because that's need to so i went back and i racked my brain a little 634 00:38:01,160 --> 00:38:05,240 more and try to come up with some way of showing property actions 635 00:38:05,830 --> 00:38:07,720 so what what's that about 636 00:38:09,260 --> 00:38:13,120 which is all and a topic so if you have lots of useful properties and 637 00:38:13,120 --> 00:38:16,440 it's a it's a said earlier these settings action but it just showed it's a 638 00:38:16,440 --> 00:38:21,470 very convenient way to make settings accessible to do you want to from corrections 639 00:38:21,970 --> 00:38:28,570 and there similarly G property action does the same thing for properties of widget object 640 00:38:29,450 --> 00:38:29,930 and 641 00:38:30,900 --> 00:38:32,510 we'll see how that works 642 00:38:33,460 --> 00:38:38,020 so i'm not going in all the details here but just explaining what what's happening 643 00:38:38,020 --> 00:38:41,010 here we have seen to have to go back to our camp that again and 644 00:38:41,010 --> 00:38:43,420 be i'm adding a two labels 645 00:38:43,880 --> 00:38:45,010 pulled out of our 646 00:38:45,490 --> 00:38:52,520 the names are lines label lines actually get again just talk about it and then 647 00:38:52,520 --> 00:38:53,720 we go to our 648 00:38:54,390 --> 00:38:56,960 the U I for it defines the geeky a menu 649 00:38:57,570 --> 00:38:59,240 and be out at the second item there 650 00:39:00,670 --> 00:39:02,030 the name lines and 651 00:39:02,340 --> 00:39:05,010 but they are the new action show lines 652 00:39:05,710 --> 00:39:07,170 which now would be a property action 653 00:39:08,050 --> 00:39:09,980 so i have to show you know that is done 654 00:39:11,100 --> 00:39:13,940 and again it's done in the in a function of all in the class and 655 00:39:15,530 --> 00:39:17,100 it is the first line there's 656 00:39:17,550 --> 00:39:22,290 G property actually you so we specify the name show lines and then we 657 00:39:23,100 --> 00:39:24,380 we use the lines object 658 00:39:24,990 --> 00:39:28,500 and you probably expect by now that pretty lines is another 659 00:39:29,690 --> 00:39:33,610 point a very banal prime instructed gets magically populated finally 660 00:39:34,290 --> 00:39:38,180 gee wouldn't you can window class pine temperature a lot well 661 00:39:38,710 --> 00:39:41,320 so that's for that one little that we just added 662 00:39:42,130 --> 00:39:47,220 and use the visible property of the label and we have another boolean target actually 663 00:39:47,220 --> 00:39:47,470 here 664 00:39:48,580 --> 00:39:48,940 and 665 00:39:50,530 --> 00:39:53,420 yet another thing that i squeezed in this last that is that 666 00:39:54,570 --> 00:39:57,540 but only can be do that but we can also 667 00:39:58,500 --> 00:39:59,080 use 668 00:39:59,640 --> 00:40:05,690 object binding here logistic in a nice way to basically connect properties of different objects 669 00:40:05,690 --> 00:40:06,670 and keep them and so 670 00:40:07,540 --> 00:40:10,390 so that's what we're using here to assess at the at to labels but we 671 00:40:10,390 --> 00:40:16,000 always want them to become visible invisible together so we can adjust we use do 672 00:40:16,000 --> 00:40:20,970 you object buying property to just connect the visible property of these two widgets 673 00:40:21,370 --> 00:40:24,840 so when i when i show the first one the second one automatically get shown 674 00:40:24,840 --> 00:40:25,360 as well 675 00:40:29,270 --> 00:40:32,420 let me show you look something about it yes 676 00:40:54,200 --> 00:40:54,990 okay so 677 00:40:56,470 --> 00:40:59,930 rest of them here's our new menu item lines i just quit that 678 00:41:00,890 --> 00:41:01,760 metropolis 679 00:41:02,500 --> 00:41:03,570 to label simply here 680 00:41:04,710 --> 00:41:07,370 and show you the code for actually counting the lines the text 681 00:41:07,980 --> 00:41:10,570 as well that that's interesting to taps 682 00:41:11,700 --> 00:41:13,280 it actually a baseline count you 683 00:41:14,360 --> 00:41:16,310 and if i top and the property again 684 00:41:18,100 --> 00:41:21,760 most of them disappeared the same time because that was the properties are all together 685 00:41:24,850 --> 00:41:25,190 and 686 00:41:26,710 --> 00:41:29,030 that was the last step so i'm actually 687 00:41:30,190 --> 00:41:31,450 and on the my samples 688 00:41:32,060 --> 00:41:34,830 i'll be and what that and if you have any questions free to ask 689 00:41:35,390 --> 00:41:40,230 thanks to take a break from this i hope are but it's actually really not 690 00:41:40,230 --> 00:41:42,930 hard automatic norm three style vacation using 691 00:41:43,520 --> 00:41:47,870 bits and pieces that are available in typically master now so it's tickets we can 692 00:41:47,870 --> 00:41:48,940 all of this would be 693 00:41:49,440 --> 00:41:51,750 would be at your disposal and 694 00:41:52,290 --> 00:41:56,980 actually did a line count you on the last step you that most complete example 695 00:41:56,980 --> 00:42:00,730 that i have comes onto some five hundred lines of C code and some two 696 00:42:00,730 --> 00:42:02,610 hundred lines of you across 697 00:42:03,400 --> 00:42:05,150 so that's not too bad considering it see 698 00:42:09,360 --> 00:42:11,810 no i that i used to be a for this 699 00:42:13,800 --> 00:42:15,950 but i hope late what we have to it as well that's just 700 00:42:18,240 --> 00:42:18,700 yes 701 00:42:26,430 --> 00:42:27,770 can repeat the question mark 702 00:42:30,920 --> 00:42:31,270 okay 703 00:42:31,850 --> 00:42:38,940 yes this first of all as i said earlier these examples including all the makefile 704 00:42:38,940 --> 00:42:42,380 integration everything is available the G T K source tree so you can go then 705 00:42:42,380 --> 00:42:45,660 local actually that this that's make for the yams 706 00:42:46,150 --> 00:42:51,960 there's also a various documentation for instance the i pointed out at some point is 707 00:42:51,960 --> 00:42:55,470 that we should some macros in G I L actually for the for the schema 708 00:42:55,470 --> 00:42:59,260 compilation part and there's a link that's of the G I O documentation but that's 709 00:42:59,260 --> 00:42:59,750 explain 710 00:43:00,540 --> 00:43:00,930 and 711 00:43:01,590 --> 00:43:05,190 maybe have documentation for some for the resource part of so an actual about that 712 00:43:07,780 --> 00:43:11,050 okay so some of this might not be wrapped a nice macros 713 00:43:11,850 --> 00:43:15,870 but some of it is and for the parts that are there should be documentation 714 00:43:15,870 --> 00:43:20,980 somewhere inside the G I O documentation but that's not necessarily easy to find so 715 00:43:20,980 --> 00:43:24,450 i try to put links to that in this 716 00:43:29,390 --> 00:43:31,290 right that's a that's a good exactly actually 717 00:43:33,290 --> 00:43:37,970 so there's a there's a nice you way of writing documentation hold how do i 718 00:43:37,970 --> 00:43:40,210 that wind kicked off and this drumming 719 00:43:40,990 --> 00:43:42,500 drumming for which 720 00:43:44,140 --> 00:43:47,870 that that's available i think it's a one about resources maybe not yet but 721 00:43:48,480 --> 00:43:49,760 we should make one available 722 00:43:55,040 --> 00:43:59,250 so there's more questions or nothing i want to say is that this is the 723 00:43:59,250 --> 00:44:03,160 location where you can actually find all of all of this online this is the 724 00:44:03,160 --> 00:44:04,900 D A P I documentation where 725 00:44:05,580 --> 00:44:09,770 that i just wanted to other point out that i found a few box and 726 00:44:09,770 --> 00:44:13,190 in the documentation gonna bend over this last night so but i showed you was 727 00:44:13,190 --> 00:44:18,360 my local fixed build and that will be all our online but the next you 728 00:44:18,360 --> 00:44:18,890 can release 729 00:44:19,570 --> 00:44:23,650 and this is a the G T K sources and you can see the night 730 00:44:23,650 --> 00:44:25,330 subdirectories where i ran 731 00:44:25,770 --> 00:44:26,640 these examples 732 00:44:31,450 --> 00:44:32,200 thank you next time 733 00:44:36,980 --> 00:44:37,750 and questions 734 00:44:39,690 --> 00:44:40,540 okay thank you
