1 00:00:01,700 --> 00:00:05,960 OK, in the last video, we looked at these pop up boxes in this video, I want to show you how to do 2 00:00:05,960 --> 00:00:11,390 things based on whether a person clicks, for instance, yes or no or whatever. 3 00:00:11,600 --> 00:00:13,970 And so we'll look at that for each of those things. 4 00:00:13,970 --> 00:00:15,470 So fairly simple. 5 00:00:15,470 --> 00:00:16,640 We can pull up our code. 6 00:00:16,640 --> 00:00:22,180 And remember, in our pupper function, we just ran this message box like this. 7 00:00:22,490 --> 00:00:29,720 Now, normally we assign widgets to things like down here, button equals the widget here. 8 00:00:29,720 --> 00:00:30,820 We just put the widget. 9 00:00:31,100 --> 00:00:36,800 Well, if we want to get the output of it and then do stuff based on it, we can just create a variable 10 00:00:36,800 --> 00:00:37,100 for it. 11 00:00:37,110 --> 00:00:39,290 So let's just call this response. 12 00:00:39,680 --> 00:00:45,010 And so that equal to this now we can do stuff based on whatever this response is. 13 00:00:45,020 --> 00:00:50,060 So if they click the yes, that will pass a thing to the response that we can then use. 14 00:00:50,060 --> 00:00:52,770 If they click on no, that will pass something else to the response. 15 00:00:52,770 --> 00:00:56,870 So we can use if they click on OK, if they click on cancel it, they click on, you know, whatever 16 00:00:56,870 --> 00:01:01,100 they click on, it'll it'll be passed to a response and then we can take some action based on it. 17 00:01:01,100 --> 00:01:07,640 So I could just tell you what the responses for each of these things are. 18 00:01:08,150 --> 00:01:12,680 But instead I think I just show you with examples because I think that's better. 19 00:01:12,690 --> 00:01:13,640 So let's create a label. 20 00:01:13,970 --> 00:01:17,510 And also if you realize how to do this, you can do this in the future. 21 00:01:17,510 --> 00:01:19,040 So you have to memorize all this stuff. 22 00:01:19,040 --> 00:01:22,340 You can just slap this on the screen and see for yourself what the output is. 23 00:01:22,670 --> 00:01:29,930 OK, so my label, this is a label and it's in root and we want the text to equal response, which is 24 00:01:30,470 --> 00:01:31,790 whatever this response is. 25 00:01:32,150 --> 00:01:32,470 Right. 26 00:01:33,050 --> 00:01:40,130 And then let's just pack this on the screen and give it a pad Y of ten just to push it down the screen 27 00:01:40,130 --> 00:01:40,610 a little bit. 28 00:01:41,080 --> 00:01:42,770 OK, so let's save this and run it. 29 00:01:42,920 --> 00:01:45,380 And so now we are on ask. 30 00:01:45,380 --> 00:01:45,700 Yes. 31 00:01:45,710 --> 00:01:46,520 No, right. 32 00:01:46,700 --> 00:01:47,210 Here we go. 33 00:01:47,510 --> 00:01:50,750 So let's see what the response for ask yes no is. 34 00:01:51,140 --> 00:01:51,410 All right. 35 00:01:51,410 --> 00:01:52,520 So click the pop up. 36 00:01:52,520 --> 00:01:54,170 Look at my pop up message. 37 00:01:54,170 --> 00:01:59,780 Yes, it returns one if we do it again and click no, it returns zero. 38 00:02:00,050 --> 00:02:01,160 So for ask yes. 39 00:02:01,160 --> 00:02:01,670 No. 40 00:02:01,850 --> 00:02:05,180 Instead of returning yes or no it returns one for yes. 41 00:02:05,180 --> 00:02:05,420 No. 42 00:02:05,420 --> 00:02:06,050 Four zero. 43 00:02:07,250 --> 00:02:07,590 Right. 44 00:02:07,790 --> 00:02:17,350 And just like anything else, you can now run an if statement so we could go if response equals one, 45 00:02:17,900 --> 00:02:25,040 then my label needs to be tapped over is. 46 00:02:26,370 --> 00:02:26,880 You know. 47 00:02:28,910 --> 00:02:30,080 You clicked. 48 00:02:32,040 --> 00:02:32,760 Yes. 49 00:02:34,830 --> 00:02:35,230 Right. 50 00:02:35,280 --> 00:02:36,000 Else. 51 00:02:42,010 --> 00:02:43,540 You clicked no. 52 00:02:46,110 --> 00:02:49,290 And then, well, let's just keep this here for now. 53 00:02:49,590 --> 00:02:54,480 So if we save this and run it, you could probably figure out what's going to happen here. 54 00:02:55,230 --> 00:02:55,920 If we click. 55 00:02:55,920 --> 00:02:57,920 Yes, we get one. 56 00:02:57,930 --> 00:02:58,410 You click. 57 00:02:58,410 --> 00:02:59,970 Yes, we click. 58 00:02:59,970 --> 00:03:02,220 No, we get zero. 59 00:03:02,220 --> 00:03:02,710 You clicked. 60 00:03:02,730 --> 00:03:04,950 No, pretty simple. 61 00:03:06,420 --> 00:03:11,400 Pretty straightforward, so now I'm going to comment this out. 62 00:03:16,070 --> 00:03:21,710 For now and just leave it like this, so let's run through here and look and see what the responses 63 00:03:21,710 --> 00:03:22,460 are for each of these. 64 00:03:22,460 --> 00:03:24,760 So ask, OK, cancel. 65 00:03:25,190 --> 00:03:26,180 You might be surprised. 66 00:03:26,180 --> 00:03:29,070 You might see some of these are going to be not what you think. 67 00:03:29,090 --> 00:03:30,170 Maybe so. 68 00:03:30,170 --> 00:03:30,770 OK, ask. 69 00:03:30,770 --> 00:03:33,770 OK, cancel, let's run this guy and see what it does. 70 00:03:35,750 --> 00:03:42,740 So look at my message, so, OK, it returns one cancel, it returns zero to OK, cancel returns one 71 00:03:42,740 --> 00:03:44,910 or zero, just like the last one. 72 00:03:45,150 --> 00:03:46,620 OK, that's not that exciting. 73 00:03:46,910 --> 00:03:49,670 Now ask questions that one does. 74 00:03:54,660 --> 00:04:02,480 So pop up, yes, it returns, yes, no, it returns no, so that we're talking about in the last video 75 00:04:02,490 --> 00:04:06,350 the difference between ask question and ask. 76 00:04:06,360 --> 00:04:08,070 Yes, no, they both say yes. 77 00:04:08,070 --> 00:04:08,370 No. 78 00:04:08,370 --> 00:04:08,700 Right. 79 00:04:09,630 --> 00:04:10,470 But one returns. 80 00:04:10,470 --> 00:04:10,800 Yes. 81 00:04:10,800 --> 00:04:12,810 No, the island returns one or zero. 82 00:04:14,070 --> 00:04:17,450 Subtle difference, but OK, so show error. 83 00:04:17,460 --> 00:04:19,500 Let's see what this one does if we save this. 84 00:04:19,950 --> 00:04:23,130 And if you remember, this one doesn't give us an option. 85 00:04:23,700 --> 00:04:25,970 It just has an OK. 86 00:04:26,270 --> 00:04:27,720 If we look there, it returns. 87 00:04:27,720 --> 00:04:31,670 OK, so if we click, pop up and click the X, it also returns. 88 00:04:31,680 --> 00:04:33,690 OK, that's kind of interesting. 89 00:04:35,640 --> 00:04:38,220 What else show error now we're on show warning. 90 00:04:40,230 --> 00:04:41,880 Say this and run it. 91 00:04:45,720 --> 00:04:47,220 Like pop up, OK? 92 00:04:47,250 --> 00:04:48,250 It returns, OK? 93 00:04:48,600 --> 00:04:50,010 And just like. 94 00:04:51,330 --> 00:05:02,640 Down here, if a response equals one, we could change this to if response equals OK or yes or whatever 95 00:05:02,640 --> 00:05:08,290 it returns, that's what you put in your if statement here to do something based on what it returns. 96 00:05:08,640 --> 00:05:10,200 So, OK, so warning. 97 00:05:10,200 --> 00:05:11,550 We got one more show info. 98 00:05:12,590 --> 00:05:16,220 And that is going to be. 99 00:05:17,870 --> 00:05:21,710 Very suspenseful, I know, OK, and it will also return. 100 00:05:21,740 --> 00:05:26,750 OK, so those are pop up boxes, pretty simple and very useful. 101 00:05:26,750 --> 00:05:28,850 You'll find all kinds of reasons for pop up boxes. 102 00:05:28,850 --> 00:05:30,200 Sometimes you want to ask a question. 103 00:05:30,210 --> 00:05:35,030 Sometimes you just want to throw an error up on the screen and have them click, OK, now you can pick 104 00:05:35,030 --> 00:05:37,100 the one you want based on that. 105 00:05:37,100 --> 00:05:39,560 It also maybe is based on the little icon that it shows. 106 00:05:39,560 --> 00:05:41,540 Maybe you don't want that big AI to be showed up. 107 00:05:41,540 --> 00:05:46,490 There may be one exclamation point to be shown up or whatever so you can play around with that. 108 00:05:46,490 --> 00:05:48,290 So that's all for up boxes. 109 00:05:48,290 --> 00:05:51,050 In the next video, we'll look at combo boxes.
