0 1 00:00:04,720 --> 00:00:06,980 Hello again, we are about to finish our project 1 2 00:00:06,980 --> 00:00:08,870 and in this lesson what I want to do, 2 3 00:00:08,870 --> 00:00:12,917 I want to create this edit menu item, 3 4 00:00:12,917 --> 00:00:14,820 the find item, okay. 4 5 00:00:14,820 --> 00:00:16,700 How can I do that? 5 6 00:00:16,700 --> 00:00:18,640 Let me run our original application first, 6 7 00:00:18,640 --> 00:00:20,600 I want to show you something here. 7 8 00:00:20,600 --> 00:00:24,470 This is the original one and I will paste here text, okay. 8 9 00:00:24,470 --> 00:00:28,504 And now let me say edit and after that find, okay. 9 10 00:00:28,504 --> 00:00:30,830 Let's see how it's working. 10 11 00:00:30,830 --> 00:00:34,000 For example, if I want to find a text here, 11 12 00:00:34,000 --> 00:00:36,260 and I say here 'lorem', okay, 12 13 00:00:36,260 --> 00:00:38,112 and after here find. 13 14 00:00:38,112 --> 00:00:41,650 Now you see our application finds for us 14 15 00:00:41,650 --> 00:00:44,350 all the 'lorem', right, it's the keyword. 15 16 00:00:44,350 --> 00:00:47,700 And what it's doing now, our application, 16 17 00:00:47,700 --> 00:00:51,520 it makes background of text yellow and the front ground 17 18 00:00:51,520 --> 00:00:55,080 of our text we are looking for is red, right. 18 19 00:00:55,080 --> 00:00:56,690 And now also what I can do, 19 20 00:00:56,690 --> 00:00:58,860 I can also replace this text okay. 20 21 00:00:58,860 --> 00:01:03,670 For example, here I will enter a new value for replace 21 22 00:01:03,670 --> 00:01:05,710 and after that I will say replace, 22 23 00:01:05,710 --> 00:01:09,330 now you see we replace ...this text. 23 24 00:01:09,330 --> 00:01:10,930 you see its here, 24 25 00:01:10,930 --> 00:01:14,893 here, and also somewhere here, 25 26 00:01:16,690 --> 00:01:18,110 and so on. 26 27 00:01:18,110 --> 00:01:20,850 I don't know there is still complicated to find them, 27 28 00:01:20,850 --> 00:01:23,928 but you understand how it's working right. 28 29 00:01:23,928 --> 00:01:28,928 Now we are going to create this find window, okay. 29 30 00:01:28,960 --> 00:01:31,780 Here what I need to do, to do that actually I will 30 31 00:01:31,780 --> 00:01:35,050 create a new class to do that, okay. 31 32 00:01:35,050 --> 00:01:36,913 And here, how can I do that, 32 33 00:01:38,933 --> 00:01:40,830 I will come here, okay. 33 34 00:01:40,830 --> 00:01:45,510 The top of my page, and here I will create a new class 34 35 00:01:45,510 --> 00:01:47,410 and I will say class FindDialog, okay. 35 36 00:01:50,360 --> 00:01:55,360 Here I will inherit this class from Toplevel window okay, 36 37 00:01:55,880 --> 00:01:57,920 and after here what I need to do, 37 38 00:01:57,920 --> 00:02:02,520 I need to say def__init, like before okay. 38 39 00:02:08,040 --> 00:02:11,550 And after here, I'm going to create my parameters, 39 40 00:02:11,550 --> 00:02:14,750 but simply I can copy these guys 40 41 00:02:16,310 --> 00:02:20,450 and paste them here, okay. 41 42 00:02:20,450 --> 00:02:24,673 Also what I need to do, I need to copy these guys right, 42 43 00:02:26,110 --> 00:02:30,640 here and paste them here again. 43 44 00:02:30,640 --> 00:02:32,960 But instead of Menu, what you need to do, 44 45 00:02:32,960 --> 00:02:35,890 I need to say here Toplevel, okay, 45 46 00:02:35,890 --> 00:02:39,260 and after that what I need to do, I need to define here 46 47 00:02:39,260 --> 00:02:44,090 geometry from my self.geometry 47 48 00:02:45,800 --> 00:02:47,320 for my window, okay. 48 49 00:02:47,320 --> 00:02:48,930 And here I will say 49 50 00:02:48,930 --> 00:02:51,080 450x200+550+200 50 51 00:02:57,510 --> 00:03:01,173 and also I want to set a title for my window, 51 52 00:03:02,107 --> 00:03:04,730 self.title, right. 52 53 00:03:04,730 --> 00:03:07,663 And for title I will say Find, 53 54 00:03:08,716 --> 00:03:10,820 and also I want to say 54 55 00:03:12,175 --> 00:03:15,925 self.resizable(False,False). 55 56 00:03:23,940 --> 00:03:26,720 Now what I need to do, I need to create my design 56 57 00:03:26,720 --> 00:03:28,150 for this window, 57 58 00:03:28,150 --> 00:03:29,691 and here what I need to do, 58 59 00:03:29,691 --> 00:03:32,274 I will create here labels okay. 59 60 00:03:33,464 --> 00:03:34,797 First I will say 60 61 00:03:36,378 --> 00:03:37,211 txtFind, 61 62 00:03:38,865 --> 00:03:42,846 or label Find, it doesn't matter, here I will say 62 63 00:03:42,846 --> 00:03:47,846 txtFind=Label(self,text="Find: ") 63 64 00:04:03,429 --> 00:04:06,153 And after that what I want to do, 64 65 00:04:06,153 --> 00:04:09,269 here I need to say txtfind.place 65 66 00:04:09,269 --> 00:04:13,510 I will use place.geomtry manager for this window 66 67 00:04:13,510 --> 00:04:16,760 (x=20,y=20). 67 68 00:04:19,668 --> 00:04:21,676 And after here what I need to do, I need to create 68 69 00:04:21,676 --> 00:04:24,093 another txtReplace=Label 69 70 00:04:31,103 --> 00:04:34,936 (self,text="Replace :"). 70 71 00:04:43,058 --> 00:04:45,011 For the Replace also I am going to use 71 72 00:04:45,011 --> 00:04:46,844 place.geometry manager 72 73 00:04:48,817 --> 00:04:53,400 txtReplace.place(x=20,y=60). 73 74 00:05:04,789 --> 00:05:06,267 After that what I need to do also, 74 75 00:05:06,267 --> 00:05:08,329 I need to create here two entries, okay, 75 76 00:05:08,329 --> 00:05:10,739 the first one is for finding, 76 77 00:05:10,739 --> 00:05:12,561 and the other one is for replacement. 77 78 00:05:12,561 --> 00:05:14,320 So I will say here 78 79 00:05:14,320 --> 00:05:19,320 self.findInput=Entry(self,width=30). 79 80 00:05:30,864 --> 00:05:34,654 Now what I will do, I will press Ctrl+D, okay, 80 81 00:05:34,654 --> 00:05:37,440 and here I will say, for second guy I will say, 81 82 00:05:37,440 --> 00:05:42,440 self.replaceInput=Entry(self,width=30). 82 83 00:05:47,803 --> 00:05:50,567 Now what I need to do, I need to use place.geomtry 83 84 00:05:50,567 --> 00:05:52,039 for these guys 84 85 00:05:52,039 --> 00:05:57,039 self.findInput.place(x=100,y=20). 85 86 00:06:05,084 --> 00:06:07,381 Again Ctrl+D, 86 87 00:06:07,381 --> 00:06:12,381 for self.replaceInput.place(x=100,y=60). 87 88 00:06:18,230 --> 00:06:19,282 After that what I need to do, 88 89 00:06:19,282 --> 00:06:21,842 remember also we need two buttons, right. 89 90 00:06:21,842 --> 00:06:23,810 The first one is Find button, and the second one 90 91 00:06:23,810 --> 00:06:26,889 will be Replace button, so I will say here 91 92 00:06:26,889 --> 00:06:31,889 self.btnFind=Button(self,text="Find"). 92 93 00:06:42,227 --> 00:06:43,977 And here for Command, 93 94 00:06:45,335 --> 00:06:49,002 actually we can create Command now or later, 94 95 00:06:50,615 --> 00:06:53,800 let's create them later okay, not now. 95 96 00:06:53,800 --> 00:06:57,562 And here also I will press Ctrl+D again 96 97 00:06:57,562 --> 00:07:02,562 self.btnReplace=Button(self,text="Replace"), 97 98 00:07:10,003 --> 00:07:12,990 I am going to use geometry manager for these guys right. 98 99 00:07:12,990 --> 00:07:16,137 And here I will say self.btnFind.place(x=200,y=90). 99 100 00:07:27,873 --> 00:07:29,456 Again, Ctrl+D, 100 101 00:07:32,372 --> 00:07:37,372 self.btnReplace.place(x=240,y=90). 101 102 00:07:40,899 --> 00:07:44,151 We've created our class now, so what I need to do now, 102 103 00:07:44,151 --> 00:07:46,604 I need to go to Main Menu, okay, 103 104 00:07:46,604 --> 00:07:49,754 and here Find is somewhere here right, 104 105 00:07:49,754 --> 00:07:52,328 File Edit, and Find is here. 105 106 00:07:52,328 --> 00:07:54,730 So I need to create here Command property, 106 107 00:07:54,730 --> 00:07:57,230 command=self.parent.find) 107 108 00:08:02,235 --> 00:08:04,845 So what I will do now, I will go to create 108 109 00:08:04,845 --> 00:08:07,262 this function here somewhere. 109 110 00:08:09,159 --> 00:08:11,826 Let's go to the end of our code, 110 111 00:08:13,540 --> 00:08:16,623 it's here right, and I will say here, 111 112 00:08:18,073 --> 00:08:21,632 def_find, okay, and here what I need to say, 112 113 00:08:21,632 --> 00:08:26,382 I need to say (self,*args):_ like before 113 114 00:08:27,430 --> 00:08:31,041 And here what I will use, now I need to create 114 115 00:08:31,041 --> 00:08:33,990 a new object from my class, 115 116 00:08:33,990 --> 00:08:35,131 so how I can do that, 116 117 00:08:35,131 --> 00:08:37,406 I will say self.find, 117 118 00:08:37,406 --> 00:08:40,573 this my class, this is my object name, 118 119 00:08:42,981 --> 00:08:45,231 =find, sorry not find. 119 120 00:08:47,324 --> 00:08:50,157 (mouse scrolling) 120 121 00:08:51,250 --> 00:08:54,165 Our class name is FindDialog right, 121 122 00:08:54,165 --> 00:08:55,927 so what I need to do, 122 123 00:08:55,927 --> 00:08:57,427 I need to use here 123 124 00:08:59,799 --> 00:09:01,307 FindDialog. 124 125 00:09:01,307 --> 00:09:06,307 And here I will say (self=parent) 125 126 00:09:07,291 --> 00:09:09,791 Now if I run my application... 126 127 00:09:12,241 --> 00:09:15,074 (mouse clicking) 127 128 00:09:16,621 --> 00:09:17,954 Here, Edit Find, 128 129 00:09:20,778 --> 00:09:23,046 FindDialog(self=parent) is not defined it said, 129 130 00:09:23,046 --> 00:09:27,213 so why its like that, let me check now. 130 131 00:09:30,473 --> 00:09:33,537 self.find=FindDialog(parent=self). 131 132 00:09:36,645 --> 00:09:39,093 So let's remove this, I need to say (parent=self). 132 133 00:09:41,255 --> 00:09:42,553 Sorry, not (self=parent), (parent=self). 133 134 00:09:45,790 --> 00:09:48,880 Okay, I will say (parent=self), now it will be fine. 134 135 00:09:48,880 --> 00:09:50,053 Run it again. 135 136 00:09:51,530 --> 00:09:54,540 Now here our application with Find, 136 137 00:09:54,540 --> 00:09:56,710 you see our Find dialog is here, 137 138 00:09:56,710 --> 00:10:00,040 so we used here Find Replace texts, 138 139 00:10:00,040 --> 00:10:01,770 two entries, two buttons. 139 140 00:10:01,770 --> 00:10:06,060 And also we used place geometry manager to place our widgets. 140 141 00:10:06,060 --> 00:10:08,510 And in this lesson we create our design 141 142 00:10:08,510 --> 00:10:10,680 for this dialog window, 142 143 00:10:10,680 --> 00:10:11,907 and in next lesson what we are going to do, 143 144 00:10:11,907 --> 00:10:15,470 we are going to create our function for this window. 144 145 00:10:15,470 --> 00:10:17,470 For now that's all, see you in the next.
