1 00:00:00,510 --> 00:00:05,830 Hello, everyone, in the last video, I have shown you how you can create a new window, which means 2 00:00:05,830 --> 00:00:10,480 a second window, adding, adding it to the main window. 3 00:00:10,890 --> 00:00:17,520 No, I will show you how you can park something on this new window, for example, a label or button, 4 00:00:17,600 --> 00:00:23,970 etc. in you do show you how you can use or how you can you add a label. 5 00:00:24,180 --> 00:00:26,730 But it is the same thing for the other items. 6 00:00:26,730 --> 00:00:31,250 You can use the same thing for to use a button or excel. 7 00:00:31,650 --> 00:00:37,980 So to use to add the button a label, sorry, the first thing that you have to do is to create it as 8 00:00:37,980 --> 00:00:38,400 always. 9 00:00:38,410 --> 00:00:47,400 So we will create label, label, equal label here so that the function and here before, before that 10 00:00:47,400 --> 00:00:53,990 we had we will not hear the name of the launch window because we had just one window. 11 00:00:54,000 --> 00:00:56,060 But in this case we have two windows. 12 00:00:56,070 --> 00:01:03,960 But our project was that we like this label or we put this label in the second window, which is the 13 00:01:03,960 --> 00:01:04,580 new window. 14 00:01:04,740 --> 00:01:11,520 So he will write the name of this new window, which means which is new, because if we write this, 15 00:01:11,520 --> 00:01:18,060 as I told you before, if we write here the name of the window, for example, new means that this label 16 00:01:18,060 --> 00:01:20,540 is special to this new window. 17 00:01:21,000 --> 00:01:25,600 So so here we have the name of the window, which is new. 18 00:01:25,920 --> 00:01:28,590 Now, the other parameters, the same thing. 19 00:01:28,590 --> 00:01:31,240 For example, here we have we will make the text, for example. 20 00:01:31,260 --> 00:01:33,890 Hi, how are you. 21 00:01:34,860 --> 00:01:37,830 And we will do nothing for anything for the full text. 22 00:01:37,830 --> 00:01:41,630 So I will like this one because it doesn't matter for the moment. 23 00:01:42,660 --> 00:01:44,300 No, we will back it. 24 00:01:44,310 --> 00:01:56,100 So we just right here love point back in this case, we will back this label in the new in the new window. 25 00:01:56,700 --> 00:01:59,240 So we will have the same thing here. 26 00:01:59,250 --> 00:02:02,490 We have this button that this window and the button. 27 00:02:02,490 --> 00:02:07,510 If we pressed the button, we will have this new window with this label, which is, hi, how are you? 28 00:02:07,830 --> 00:02:11,580 But if we press the button another time, we will have new in another window. 29 00:02:11,580 --> 00:02:13,980 And if we press another thing, we have new window. 30 00:02:14,340 --> 00:02:20,730 But it's not professional because the project say that if you press here, we will have a new window. 31 00:02:21,510 --> 00:02:27,570 But if you press another time and this window is always, always open, we can't. 32 00:02:27,570 --> 00:02:30,450 We won't we don't want to have another window. 33 00:02:30,630 --> 00:02:37,100 So if we have these two cases, if we have no window and we press the button, we will have we will 34 00:02:37,140 --> 00:02:37,860 create one. 35 00:02:38,460 --> 00:02:43,710 But if the window is always open, if we press here, we don't want to have another one. 36 00:02:43,950 --> 00:02:47,120 So to fix this, we make some changes in our program. 37 00:02:47,610 --> 00:02:52,800 The first thing that we have to do is to declare a variable, a temporary variable that will take the 38 00:02:52,800 --> 00:02:55,460 rule of the opening window or closed. 39 00:02:55,830 --> 00:03:01,610 So we will call it, for example, of Ola or I will be, for example. 40 00:03:02,310 --> 00:03:04,230 So I will make it global. 41 00:03:04,680 --> 00:03:09,360 So global value will be and I will put it outside the function. 42 00:03:09,360 --> 00:03:13,980 I will give it to value zero, initialize it to the value zero. 43 00:03:14,610 --> 00:03:16,680 Then this with new window. 44 00:03:16,680 --> 00:03:22,980 I will put it global two because we need it for the conditions that will come next. 45 00:03:23,310 --> 00:03:26,040 So we will continue the same thing here. 46 00:03:26,040 --> 00:03:29,010 We will give it, we will give it a place in the memory. 47 00:03:29,040 --> 00:03:32,260 So we will give it the you or not which means empty. 48 00:03:32,850 --> 00:03:41,700 So here we have these two variables is B is a temporary one, but it will take the load of the closed 49 00:03:41,700 --> 00:03:42,690 window or opened. 50 00:03:43,170 --> 00:03:49,920 Then we have here this global variable, which is new that will have the value of this window, the 51 00:03:49,920 --> 00:03:50,460 new window. 52 00:03:50,850 --> 00:03:54,210 So I we got all this for the moment. 53 00:03:54,720 --> 00:03:55,170 No. 54 00:03:55,650 --> 00:04:03,850 So we have to cut all this with the label because the the creation of the label is included with the 55 00:04:03,870 --> 00:04:04,850 creation of the window. 56 00:04:04,860 --> 00:04:06,360 So we will cut all this. 57 00:04:06,930 --> 00:04:15,450 No, as we said, we want that if this temporary variable, for example, if this V equals zero, means 58 00:04:15,450 --> 00:04:23,790 that we we haven't created any if if the be equal zero, that means that we haven't created any windows 59 00:04:23,790 --> 00:04:24,060 yet. 60 00:04:24,450 --> 00:04:26,760 So here we will create a new one. 61 00:04:27,240 --> 00:04:34,950 So we will put this line of code which will create the window and give it name and icon zero and the 62 00:04:34,950 --> 00:04:42,450 label to then if this B doesn't equal zero means that we have created a window. 63 00:04:42,780 --> 00:04:45,000 But if we created a window, that is true. 64 00:04:45,000 --> 00:04:51,270 In other cases, there is the first case, which is we created a window, then we closed it and there 65 00:04:51,270 --> 00:04:57,060 is another case which is we created a window but is all always open open. 66 00:04:57,270 --> 00:04:59,790 So in this case, we will create we will make another. 67 00:05:00,390 --> 00:05:04,420 For example, here we have El Al means that this doesn't equal zero. 68 00:05:04,840 --> 00:05:06,420 No, we will do this. 69 00:05:06,420 --> 00:05:14,640 We do a condition to verify these two cases, which is we have created a window then we it or we have 70 00:05:14,640 --> 00:05:15,630 created a window. 71 00:05:15,810 --> 00:05:18,990 But it is always created in this case. 72 00:05:18,990 --> 00:05:20,530 I forgot something here. 73 00:05:20,820 --> 00:05:26,540 If we create a window, so in this case we have created a window, so we will both be equal. 74 00:05:26,700 --> 00:05:31,190 One means that if be equal one, that means that we have created a window. 75 00:05:31,980 --> 00:05:38,880 Now here we will make a condition that is a function called Infl Windows eight for exists. 76 00:05:39,570 --> 00:05:46,380 This function we will return to if the window is open, so we will use it here. 77 00:05:46,380 --> 00:05:47,640 If new. 78 00:05:47,910 --> 00:05:54,190 That info exists means if the window exists, it is not closed. 79 00:05:54,210 --> 00:05:55,570 It is always open. 80 00:05:55,890 --> 00:06:00,330 In this case, we will both be equal one sorry, equal one. 81 00:06:01,110 --> 00:06:07,950 But if it is not it it doesn't exist means that we have created a window. 82 00:06:07,950 --> 00:06:09,470 But we closed it after this. 83 00:06:09,960 --> 00:06:15,900 In this case we will create a new window, which is we will put these lines of code so we see if it 84 00:06:15,900 --> 00:06:16,380 works. 85 00:06:16,380 --> 00:06:18,150 Here we have the main window. 86 00:06:18,480 --> 00:06:20,600 If we press the button, we have this new window. 87 00:06:20,610 --> 00:06:21,870 If we press another time. 88 00:06:26,880 --> 00:06:35,120 So if we're on our program here, we see that this is the first window, so there is a problem here. 89 00:06:37,720 --> 00:06:38,680 We will see the program. 90 00:06:42,460 --> 00:06:46,490 All right, and so we run our program. 91 00:06:49,150 --> 00:06:51,700 He had our window set up, 92 00:06:56,260 --> 00:07:02,710 so if we were on our program, you can see this is our main window, if we press the button, we have 93 00:07:02,710 --> 00:07:03,570 this new window. 94 00:07:03,910 --> 00:07:07,360 If you press another time, I'm sorry, there is new window. 95 00:07:07,360 --> 00:07:09,520 There is a problem in the code. 96 00:07:10,100 --> 00:07:12,090 We see it here. 97 00:07:13,330 --> 00:07:14,170 This is the problem. 98 00:07:14,180 --> 00:07:15,540 The two equals here. 99 00:07:16,000 --> 00:07:18,320 So we will run it another time. 100 00:07:18,970 --> 00:07:20,050 This is the window. 101 00:07:20,200 --> 00:07:23,180 If we press another time, there is no other window. 102 00:07:23,200 --> 00:07:25,650 This is just where there is just one window. 103 00:07:26,020 --> 00:07:29,430 If you close it and we press another time, we have this new one. 104 00:07:30,550 --> 00:07:41,220 So that was the code of today, how to make a label in a new window and how to fix that problem too. 105 00:07:41,500 --> 00:07:45,480 Don't open a lot of windows when we press the button. 106 00:07:46,360 --> 00:07:49,930 So I see you in the next video and stay safe by.
