0 1 00:00:04,980 --> 00:00:06,250 Hello again, in previous lecture 1 2 00:00:06,250 --> 00:00:09,070 what we did, let me run our application first. 2 3 00:00:09,070 --> 00:00:11,390 We created our functions for font family 3 4 00:00:11,390 --> 00:00:12,950 and also font size. 4 5 00:00:12,950 --> 00:00:14,510 And in this lesson, what I want to do, 5 6 00:00:14,510 --> 00:00:16,900 I want to create a function 6 7 00:00:16,900 --> 00:00:18,693 to make our text bold. 7 8 00:00:19,650 --> 00:00:21,170 What I need to do first of all, 8 9 00:00:21,170 --> 00:00:23,550 I need to go to my toolbar 9 10 00:00:23,550 --> 00:00:24,710 and find my button. 10 11 00:00:24,710 --> 00:00:27,590 My button is here, so here I will create 11 12 00:00:27,590 --> 00:00:29,560 a command property for my button first. 12 13 00:00:29,560 --> 00:00:30,510 I will say command, 13 14 00:00:32,350 --> 00:00:33,743 command equals, 14 15 00:00:34,850 --> 00:00:36,790 sorry command, 15 16 00:00:36,790 --> 00:00:38,430 yes is equals, 16 17 00:00:38,430 --> 00:00:40,430 I will say, self parent 17 18 00:00:41,330 --> 00:00:44,783 dot change bold. 18 19 00:00:46,020 --> 00:00:50,010 Parent means here my main application is here, that one. 19 20 00:00:50,010 --> 00:00:54,140 So I will create this function in my main class. 20 21 00:00:54,140 --> 00:00:56,770 Main application class here, I will come here, 21 22 00:00:56,770 --> 00:00:59,900 and create this function, I will say def 22 23 00:00:59,900 --> 00:01:00,943 change bold. 23 24 00:01:01,877 --> 00:01:06,050 And after self I will use args. 24 25 00:01:06,050 --> 00:01:07,230 It's parameter. 25 26 00:01:07,230 --> 00:01:08,500 And here what I need to do, 26 27 00:01:08,500 --> 00:01:11,813 if you want to change your text. 27 28 00:01:13,700 --> 00:01:16,550 First of all, we need to know our text properties. 28 29 00:01:16,550 --> 00:01:18,077 This is important. 29 30 00:01:18,077 --> 00:01:20,590 And how we can get our text properties, 30 31 00:01:20,590 --> 00:01:22,050 to that we need to create here. 31 32 00:01:22,050 --> 00:01:26,380 Let's create a variable font or text property. 32 33 00:01:26,380 --> 00:01:28,000 Let's say text. 33 34 00:01:28,000 --> 00:01:32,380 Text property or let's say text pro equals. 34 35 00:01:32,380 --> 00:01:34,070 I will say here font 35 36 00:01:34,070 --> 00:01:36,260 my function, 36 37 00:01:36,260 --> 00:01:38,173 after that, again, I need to say font. 37 38 00:01:39,170 --> 00:01:44,170 And here will say font equals my self dot text editor. 38 39 00:01:45,440 --> 00:01:49,420 And here I need to use square brackets and font. 39 40 00:01:49,420 --> 00:01:52,180 This guy, this function will return me 40 41 00:01:52,180 --> 00:01:54,620 text properties of text editor. 41 42 00:01:54,620 --> 00:01:57,590 But before that, what I need to do let's print it out, 42 43 00:01:57,590 --> 00:01:58,666 I need to use something else, 43 44 00:01:58,666 --> 00:02:02,749 I will say here, by the way, text pro dot actual, 44 45 00:02:04,071 --> 00:02:05,218 this function. 45 46 00:02:05,218 --> 00:02:07,551 Now if I run my application. 46 47 00:02:11,244 --> 00:02:12,827 Now we see it here. 47 48 00:02:15,466 --> 00:02:17,745 Here I will type something, this one, 48 49 00:02:17,745 --> 00:02:20,128 and if I click this bold button. 49 50 00:02:20,128 --> 00:02:21,128 Now, see it. 50 51 00:02:22,687 --> 00:02:25,385 You see here, this is my text properties 51 52 00:02:25,385 --> 00:02:28,950 and overstrike size is 10 pixels, 52 53 00:02:28,950 --> 00:02:30,363 weight is normal. 53 54 00:02:30,363 --> 00:02:32,090 Weight means here bold or not. 54 55 00:02:32,090 --> 00:02:35,230 If it is normal, that means our text is not bold. 55 56 00:02:35,230 --> 00:02:38,810 The family and slant, and also underline. 56 57 00:02:38,810 --> 00:02:41,870 Underline for zero means it is not underline. 57 58 00:02:41,870 --> 00:02:43,077 It doesn't have underline. 58 59 00:02:43,077 --> 00:02:45,550 If it value is one, that means our text 59 60 00:02:45,550 --> 00:02:47,735 is already underlined. 60 61 00:02:47,735 --> 00:02:48,660 It's important. 61 62 00:02:48,660 --> 00:02:51,850 So here, for the weight, what I need to say, 62 63 00:02:51,850 --> 00:02:54,820 if you want to learn weight of your font, 63 64 00:02:54,820 --> 00:02:56,060 if it is bold or not, 64 65 00:02:56,060 --> 00:02:58,766 you need to say here weight, simply. 65 66 00:02:58,766 --> 00:03:00,953 And now if I run my application again. 66 67 00:03:02,980 --> 00:03:04,790 Now I will close this one, 67 68 00:03:04,790 --> 00:03:09,180 and for the weight why it didn't return me here. 68 69 00:03:09,180 --> 00:03:12,743 Print text pro actual

close it. 72 73 00:03:23,720 --> 00:03:25,470 You see, it said normal. 73 74 00:03:25,470 --> 00:03:28,510 That means my text is not bold. 74 75 00:03:28,510 --> 00:03:30,970 So how can I change my...
