1 00:00:00,660 --> 00:00:07,500 Hello, everyone, and the last video I have shown you how you can create a button and do some editing 2 00:00:07,500 --> 00:00:07,840 on it. 3 00:00:08,280 --> 00:00:17,640 Now I will show you how you can add or create a function that will be executed when we click the button. 4 00:00:17,940 --> 00:00:24,240 So, for example, if we want that, when we click here, when we click the button, we will see a label 5 00:00:24,240 --> 00:00:25,040 or a text here. 6 00:00:25,560 --> 00:00:28,530 So we need to add a function that will do this work. 7 00:00:29,280 --> 00:00:35,010 So before that, I have a notes I want to tell you about the bad X and by the way, it functions. 8 00:00:35,460 --> 00:00:44,580 So if we write this functions inside the the button function, which is when we are creating the button, 9 00:00:45,360 --> 00:00:50,690 it it is not the same thing if we write these functions in the back. 10 00:00:51,060 --> 00:00:51,450 Why? 11 00:00:51,450 --> 00:00:59,940 Because here in the in the in the bottom function, if we write for example here but X equal duty and 12 00:00:59,940 --> 00:01:07,080 Budhwar equals money, that means that we will make a space between the text here, the text and the 13 00:01:07,090 --> 00:01:08,420 border of the button. 14 00:01:08,820 --> 00:01:11,220 The same thing for the for the labels. 15 00:01:11,220 --> 00:01:18,900 If we have a label and we, we put the X and by the way, inside or in the creation of the button or 16 00:01:18,900 --> 00:01:25,080 the label, that means that we will make a space between the text and the border of the button or the 17 00:01:25,080 --> 00:01:32,070 label, which means for that I told you that we will have the the width and the height of the button 18 00:01:32,070 --> 00:01:35,630 when we control it with with the button and by the way. 19 00:01:35,910 --> 00:01:42,780 But if we want to make a space between the button and the border of the window, for example, we want 20 00:01:42,780 --> 00:01:44,080 to move it down, for example. 21 00:01:44,430 --> 00:01:51,810 So in this case, we will use the the functions, the putting functions inside the back function. 22 00:01:52,080 --> 00:02:00,510 So here in the back, if we will, if we want, for example, we make pad Y equals 20, for example, 23 00:02:00,900 --> 00:02:08,490 we will see here that we have some space between the button and the border of the window, because if 24 00:02:08,490 --> 00:02:16,020 we use the padding in the back function, we will control the items between, for example, if we have 25 00:02:16,020 --> 00:02:21,710 two items that we will make a space between these two, these two two items. 26 00:02:22,050 --> 00:02:27,450 But if we have just one item in this case, we will make a space between the item and the border of 27 00:02:27,450 --> 00:02:27,930 the window. 28 00:02:28,570 --> 00:02:29,760 Same thing for the pathway. 29 00:02:30,060 --> 00:02:38,370 But so if we write if we use the padding functions in the back here, we will make a space between the 30 00:02:38,400 --> 00:02:44,070 items or between the item and boarded the windows, the window by voters. 31 00:02:44,490 --> 00:02:51,710 But if we will, we will use the building functions in the creation of the button or labor. 32 00:02:52,560 --> 00:03:00,300 In this case, we will make a space between the text and the borders, or we can say we will control 33 00:03:00,300 --> 00:03:03,280 the width and the height of this items. 34 00:03:04,160 --> 00:03:13,810 So we will will back to our main subject, which is how to create a function or a command for this button. 35 00:03:14,130 --> 00:03:21,000 So as I told you, we want if we click on this button, we will have a text saying, for example, hi, 36 00:03:21,000 --> 00:03:21,690 how are you today? 37 00:03:22,410 --> 00:03:25,680 So in this case, we will use the function called command. 38 00:03:26,640 --> 00:03:29,640 This function will execute this function. 39 00:03:29,640 --> 00:03:33,180 Command will execute the function that will write this text. 40 00:03:33,360 --> 00:03:40,150 So we will write, for example, come on then one after that we will write the name of the function. 41 00:03:40,170 --> 00:03:43,160 So for example, make it click for the moment. 42 00:03:43,170 --> 00:03:50,700 I didn't define the function yet, but I will just write the name of the function, which is click. 43 00:03:50,850 --> 00:03:53,740 After that, I will define it in the beginning of the program. 44 00:03:54,240 --> 00:04:01,050 So as you can see here, we didn't push the buttons, but we know that in the programming, if we call 45 00:04:01,050 --> 00:04:05,730 any function, we need to add the parentheses so that we will say that this is a function. 46 00:04:05,970 --> 00:04:11,440 But in this case, we don't need it, because if we like this, just like this, come on, that equal 47 00:04:11,460 --> 00:04:12,690 the name of the function. 48 00:04:13,260 --> 00:04:15,740 We can't use the function with parameters. 49 00:04:15,750 --> 00:04:16,410 In this case. 50 00:04:16,500 --> 00:04:22,560 There is there is another case that we can use the parameters, but in this case we can't use parameters 51 00:04:22,770 --> 00:04:25,410 so that we can't write the buttons. 52 00:04:25,500 --> 00:04:27,970 So we write just the name of the function and it will. 53 00:04:28,710 --> 00:04:34,010 So here we like the function that function, the click function, for example. 54 00:04:34,020 --> 00:04:38,750 So def click But this is the columns. 55 00:04:39,360 --> 00:04:45,390 So I told you that we want if we click on this button we will have a text. 56 00:04:45,570 --> 00:04:52,230 So inside this function we will create our label because if we write the label outside, this function 57 00:04:52,230 --> 00:04:59,850 means that when we run our program it will create the label without waiting for the click or something 58 00:04:59,850 --> 00:04:59,940 like. 59 00:05:00,390 --> 00:05:08,820 So if you wanted to to be printed or to be created after clicking on the button, so we need you to 60 00:05:08,820 --> 00:05:14,430 create it inside the creation or inside the function that will be pressed. 61 00:05:14,640 --> 00:05:24,430 OK, so we give this label a name, for example, love, equal label labor and then parentheses. 62 00:05:24,720 --> 00:05:27,590 We will make this label in the roots. 63 00:05:28,260 --> 00:05:33,120 Then the text equals 64 00:05:35,730 --> 00:05:41,320 the word, you know, to today. 65 00:05:41,670 --> 00:05:43,770 So when we press, we want that. 66 00:05:43,770 --> 00:05:45,880 When we press the button, we will see this text. 67 00:05:45,900 --> 00:05:46,590 Hi, Howard. 68 00:05:46,740 --> 00:05:47,150 Hi there. 69 00:05:47,160 --> 00:05:47,710 How are you doing?
