0 1 00:00:04,578 --> 00:00:05,870 In this lecture we are going to learn 1 2 00:00:05,870 --> 00:00:09,140 how we can create message boxes for our applications. 2 3 00:00:09,140 --> 00:00:11,210 Here I already create our template. 3 4 00:00:11,210 --> 00:00:12,620 But here what we need to do here, 4 5 00:00:12,620 --> 00:00:15,880 we need to say from tkinter, 5 6 00:00:15,880 --> 00:00:18,880 from tkinter import message box, okay. 6 7 00:00:18,880 --> 00:00:21,480 If you don't call this message box, 7 8 00:00:21,480 --> 00:00:23,250 if you don't import message box, 8 9 00:00:23,250 --> 00:00:26,920 we cannot use message box for our application, okay. 9 10 00:00:26,920 --> 00:00:28,290 So what we need to do here, 10 11 00:00:28,290 --> 00:00:30,440 I will create two buttons, okay, 11 12 00:00:30,440 --> 00:00:34,890 and button one is equal to I will say, 12 13 00:00:34,890 --> 00:00:39,371 I will use ttk module, dot button constructor method. 13 14 00:00:39,371 --> 00:00:44,000 And here root, first parameter, and second one 14 15 00:00:44,000 --> 00:00:46,803 will be, it's text property for text property 15 16 00:00:48,369 --> 00:00:52,470 I will say delete first, for first one, 16 17 00:00:52,470 --> 00:00:55,943 and the next one will be command. 17 18 00:00:56,780 --> 00:01:01,370 And command will be callback this is my definition name, okay. 18 19 00:01:01,370 --> 00:01:03,840 And now I will use grid geometry manager, of course. 19 20 00:01:03,840 --> 00:01:08,840 Grid, and here I will say row is equal to zero, 20 21 00:01:10,760 --> 00:01:15,760 and column is, column is equal to zero. 21 22 00:01:16,740 --> 00:01:20,600 Okay, and now I will press control and D, 22 23 00:01:20,600 --> 00:01:23,363 Control D, and now here, I will say button two, 23 24 00:01:24,710 --> 00:01:29,710 and for this one, I will say info only. 24 25 00:01:34,320 --> 00:01:38,170 And for callback function, I will name it call back two. 25 26 00:01:38,170 --> 00:01:40,790 Okay, I will create two different definitions 26 27 00:01:40,790 --> 00:01:42,770 for my buttons, okay. 27 28 00:01:42,770 --> 00:01:45,530 If I run my application now, actually I will get error, 28 29 00:01:45,530 --> 00:01:48,553 so I have to create here my callback function, 29 30 00:01:50,450 --> 00:01:55,340 callback, and here what I need to do 30 31 00:01:55,340 --> 00:01:57,940 let's say here pass for first one, 31 32 00:01:57,940 --> 00:02:02,633 and after that I need to create callback2, callback2. 32 33 00:02:04,500 --> 00:02:08,130 And here let's say pass again. 33 34 00:02:08,130 --> 00:02:09,883 Now if I run my application, 34 35 00:02:11,870 --> 00:02:13,610 as you see now here, 35 36 00:02:13,610 --> 00:02:16,860 I did not use grid geometry manager for button two. 36 37 00:02:16,860 --> 00:02:19,070 So let's do it also here. 37 38 00:02:19,070 --> 00:02:20,810 Actually no, it says I used used, 38 39 00:02:20,810 --> 00:02:24,500 but I need to say here for the column will be one. 39 40 00:02:24,500 --> 00:02:28,740 Okay, and if I run it again, now as you see it's here. 40 41 00:02:28,740 --> 00:02:33,300 But let's add some pads here for top and also for left. 41 42 00:02:33,300 --> 00:02:35,833 How we can do that, here I can say, 42 43 00:02:37,212 --> 00:02:42,212 pad Y is equal to 25 43 44 00:02:43,000 --> 00:02:48,000 and pad X is let's say 50, okay. 44 45 00:02:48,440 --> 00:02:51,190 I think it will be more reasonable now. 45 46 00:02:51,190 --> 00:02:52,100 Yep, it is more reasonable 46 47 00:02:52,100 --> 00:02:55,120 and they are not very close now the buttons. 47 48 00:02:55,120 --> 00:02:56,460 So what we need to do now, 48 49 00:02:56,460 --> 00:02:58,340 we need to create our functions, right. 49 50 00:02:58,340 --> 00:03:02,470 For this, the click and connect functions for our buttons. 50 51 00:03:02,470 --> 00:03:04,030 And so what we need to do here 51 52 00:03:04,030 --> 00:03:07,940 for callback for the first button, the text is delete, 52 53 00:03:07,940 --> 00:03:11,450 right, the second one, the text is info. 53 54 00:03:11,450 --> 00:03:13,500 And here I need to show you how we can 54 55 00:03:13,500 --> 00:03:15,190 create message boxes. 55 56 00:03:15,190 --> 00:03:16,620 Here, firstly I will create 56 57 00:03:16,620 --> 00:03:19,210 a variable, and I will name it mbox, okay, 57 58 00:03:19,210 --> 00:03:21,360 it's message box, and after that I will say here 58 59 00:03:21,360 --> 00:03:23,060 message box dot 59 60 00:03:23,060 --> 00:03:24,670 As you see now there are many 60 61 00:03:24,670 --> 00:03:26,020 different message boxes actually, 61 62 00:03:26,020 --> 00:03:31,020 but here ask question, ask yes/no, ask yes/no/cancel, 62 63 00:03:34,050 --> 00:03:39,050 and for now I want to show you two different message boxes, 63 64 00:03:39,130 --> 00:03:40,810 okay, and it's enough. 64 65 00:03:40,810 --> 00:03:43,310 Usually all of them is very similar. 65 66 00:03:43,310 --> 00:03:46,660 First one is maybe ask question message box, okay. 66 67 00:03:46,660 --> 00:03:50,060 Ask questions, and here, the first one, 67 68 00:03:50,060 --> 00:03:54,580 the first parameter will be our text, okay. 68 69 00:03:54,580 --> 00:03:56,850 Sorry this is our title, 69 70 00:03:56,850 --> 00:03:59,263 and the other one will be our text. 70 71 00:04:01,150 --> 00:04:04,987 After delete I will say, for example, 71 72 00:04:04,987 --> 00:04:07,000 "Are you sure?" 72 73 00:04:07,000 --> 00:04:12,000 Okay, and other one is we can use here, icon, 73 74 00:04:12,000 --> 00:04:15,240 but let me show you run our application first 74 75 00:04:15,240 --> 00:04:18,090 and after that I will explain you how we can use icons, 75 76 00:04:18,090 --> 00:04:21,617 okay, and here, what we need to say, we need to say, 76 77 00:04:21,617 --> 00:04:22,450 "If Mbox." 77 78 00:04:28,388 --> 00:04:30,160 Mbox is equals equals yes, okay. 78 79 00:04:30,160 --> 00:04:33,760 Because we will have two buttons for ask question message box. 79 80 00:04:33,760 --> 00:04:36,229 First one is yes, the other one is no, okay, 80 81 00:04:36,229 --> 00:04:39,043 if the user clicks yes button, 81 82 00:04:39,043 --> 00:04:41,063 we need to say here something. 82 83 00:04:42,531 --> 00:04:45,040 Let's say print deleted, okay. 83 84 00:04:45,040 --> 00:04:47,180 If not, we need to say here, 84 85 00:04:47,180 --> 00:04:52,180 else, for else I will say print not deleted. 85 86 00:04:56,550 --> 00:04:58,550 And let me run our application now, 86 87 00:04:58,550 --> 00:05:01,260 and after that I want to you show you how we can use icons. 87 88 00:05:01,260 --> 00:05:04,283 If I click delete, as you can see now it's here. 88 89 00:05:06,906 --> 00:05:08,990 Actually, now here let me run it again, 89 90 00:05:08,990 --> 00:05:10,470 I want to show you something. 90 91 00:05:10,470 --> 00:05:12,530 It's here okay, delete. 91 92 00:05:12,530 --> 00:05:14,910 As you see delete is here, this is our title. 92 93 00:05:14,910 --> 00:05:15,800 Okay, the first one. 93 94 00:05:15,800 --> 00:05:18,470 And second one is our text, okay. 94 95 00:05:18,470 --> 00:05:21,370 But here, all the message box they have, 95 96 00:05:21,370 --> 00:05:23,670 they have specific icons, but if you want 96 97 00:05:23,670 --> 00:05:26,697 to use another icon for your message box you can do it. 97 98 00:05:26,697 --> 00:05:30,350 For example, here is ask question and that's 98 99 00:05:30,350 --> 00:05:32,228 why its icon is question mark, right. 99 100 00:05:32,228 --> 00:05:34,420 For example, if you want to use another icon, 100 101 00:05:34,420 --> 00:05:35,420 how you can do that. 101 102 00:05:38,097 --> 00:05:41,220 Let's close this one and here for icon property, 102 103 00:05:41,220 --> 00:05:45,812 we need to say here icon is, sorry, 103 104 00:05:45,812 --> 00:05:50,812 we need to say here icon is equal to for example 104 105 00:05:51,130 --> 00:05:52,651 let's use warning, okay, 105 106 00:05:52,651 --> 00:05:56,173 and now if I run my application again, 106 107 00:05:58,999 --> 00:06:03,010 delete, as you see now our icon is different. 107 108 00:06:03,010 --> 00:06:07,560 And now, if I say yes, and you see it's here, 108 109 00:06:07,560 --> 00:06:11,580 check here on our console it said deleted. 109 110 00:06:11,580 --> 00:06:15,700 If I say no, it said not deleted, okay. 110 111 00:06:15,700 --> 00:06:19,210 And also, let's create for the other message box 111 112 00:06:19,210 --> 00:06:23,060 it will be show info message box, okay. 112 113 00:06:23,060 --> 00:06:25,270 That one was ask question message box, 113 114 00:06:25,270 --> 00:06:27,000 here for callback two. 114 115 00:06:27,000 --> 00:06:29,860 I will create here, I will not create mbox 115 116 00:06:29,860 --> 00:06:32,470 because I will not use if and else statement this way. 116 117 00:06:32,470 --> 00:06:36,140 I will create message box, show info, okay. 117 118 00:06:39,880 --> 00:06:44,880 Here what I need to do, I need to use first one is my title. 118 119 00:06:45,600 --> 00:06:50,600 And second one will be, my text, okay, well done. 119 120 00:06:50,760 --> 00:06:54,341 And this one is the show info message box, it has 120 121 00:06:54,341 --> 00:06:56,510 only one button, let's run it now. 121 122 00:06:58,400 --> 00:07:02,030 If I click info button, you see it said well done 122 123 00:07:02,030 --> 00:07:04,304 and now it's our icon by default. 123 124 00:07:04,304 --> 00:07:07,230 This icon you can of course change it, 124 125 00:07:07,230 --> 00:07:08,410 like you can use icon 125 126 00:07:08,410 --> 00:07:11,320 and change your icon for your message box. 126 127 00:07:11,320 --> 00:07:15,380 And if I click okay, as you see, nothing happens 127 128 00:07:15,380 --> 00:07:18,580 but of course we can say here something. 128 129 00:07:18,580 --> 00:07:19,923 For example, we can say, 129 130 00:07:23,445 --> 00:07:24,950 print you clicked okay. 130 131 00:07:31,640 --> 00:07:35,123 And now, if I run it again, 131 132 00:07:37,090 --> 00:07:42,090 info, if I say okay, as you see now, you clicked okay. 132 133 00:07:42,610 --> 00:07:44,560 This is how we can use message boxes 133 134 00:07:44,560 --> 00:07:45,750 for our applications. 134 135 00:07:45,750 --> 00:07:47,733 For now, that's all, see you next.
