1 00:00:01,400 --> 00:00:04,280 So let's create our loop. 2 00:00:05,180 --> 00:00:14,720 While true, I'll check for the event and values and we will Cranton, so I will choose. 3 00:00:16,390 --> 00:00:20,970 A full year led to this one and nothing happened. 4 00:00:22,860 --> 00:00:28,290 Let's click on ACAP, nothing will happen until we click a button. 5 00:00:28,500 --> 00:00:34,770 OK, but we can even exit now will not allow us to exit the window. 6 00:00:37,820 --> 00:00:45,320 OK, so we have the problem is we have not tell W when to quit. 7 00:00:48,000 --> 00:00:54,780 So if event equals S.G., they'll win close. 8 00:00:56,910 --> 00:01:05,670 Break, let me run this again now, when we click on this will exit correctly, and if we click on exit, 9 00:01:05,670 --> 00:01:06,920 nothing else will work. 10 00:01:07,050 --> 00:01:10,700 But I'm only showing you why this error message appears. 11 00:01:10,710 --> 00:01:13,770 Let's commend this and run it again. 12 00:01:16,150 --> 00:01:25,420 This, by default, will close the wind, but we have not exited blue yet, so Delu still trying to 13 00:01:25,420 --> 00:01:27,860 read from the window which is closed. 14 00:01:28,000 --> 00:01:34,690 This is why it's giving us this error message, trying to read a closed window. 15 00:01:35,200 --> 00:01:39,460 OK, now let's modify this. 16 00:01:42,540 --> 00:01:55,800 If event equals exit or OK, now our window will be closed properly, but I want also to trigger some 17 00:01:55,800 --> 00:02:03,720 events when we play and select this button and this button and other buttons, for instance. 18 00:02:04,200 --> 00:02:05,260 So how can we do this? 19 00:02:05,670 --> 00:02:13,950 There is a property for each element that it will allow it to create event. 20 00:02:14,250 --> 00:02:19,260 To do this, we will use something called enable event. 21 00:02:19,620 --> 00:02:28,440 So by default, the folder brass will fill in the value for this input when we select a folder. 22 00:02:28,860 --> 00:02:33,330 So here we will enable event equals to. 23 00:02:33,660 --> 00:02:35,670 Let's check what this will do. 24 00:02:36,780 --> 00:02:42,140 Now, when we choose our folders, it now had created an event. 25 00:02:42,600 --> 00:02:44,880 Let's try another one. 26 00:02:44,880 --> 00:02:46,700 We haven't put anything in here. 27 00:02:46,800 --> 00:02:49,890 I'll choose another folder and nothing happens. 28 00:02:50,280 --> 00:02:58,530 So any event will fire an event when a control or when an element is changed. 29 00:02:58,980 --> 00:03:03,810 OK, so we should do the same thing with the destination. 30 00:03:04,050 --> 00:03:07,920 OK, let's adjust the width of this. 31 00:03:07,950 --> 00:03:10,910 So it will be more readable. 32 00:03:11,220 --> 00:03:13,770 We can also give it a tool tip. 33 00:03:14,220 --> 00:03:18,130 Select this nation folder. 34 00:03:18,480 --> 00:03:27,950 Let's do the same thing in here and we will see what a tool is because this is sort of enhancement. 35 00:03:27,960 --> 00:03:28,560 It's not. 36 00:03:34,600 --> 00:03:40,740 Now, when I hoover on the button, it will play select source or destination folder. 37 00:03:41,470 --> 00:03:44,400 OK, now we have completed our interface. 38 00:03:44,680 --> 00:03:52,010 Let's put our logic in the loop first when I select a source folder. 39 00:03:52,450 --> 00:04:01,200 I want to scan the files in this folder and populate the multiline with the file names. 40 00:04:01,630 --> 00:04:03,220 So let's do this. 41 00:04:06,320 --> 00:04:17,080 I'll check if an event equals source and we are tracking the event, if it equal the kenin. 42 00:04:17,810 --> 00:04:29,400 OK, then source will equal to Earth values source and this is to get the actual content of the input 43 00:04:29,750 --> 00:04:30,220 box. 44 00:04:30,530 --> 00:04:38,780 We could have used the browse button and gave it a key, but in anyway, we have the same value in the 45 00:04:38,780 --> 00:04:39,080 input. 46 00:04:39,800 --> 00:04:41,430 Now let's grab the extension. 47 00:04:42,020 --> 00:04:55,640 This will be values of E at the end of sixty eight 16 values of equity and now files will equal open 48 00:04:56,150 --> 00:05:00,470 source that are low, for example. 49 00:05:00,920 --> 00:05:03,590 And in here we will pass the extension. 50 00:05:04,220 --> 00:05:04,570 OK. 51 00:05:05,340 --> 00:05:15,210 We have converted the values of souls to a path using the past Nebris, we have grabbed extensor if 52 00:05:15,210 --> 00:05:24,150 the user had changed it, and then we have created our globe to get the files from this path. 53 00:05:24,690 --> 00:05:29,810 And now the files will equal to list of files. 54 00:05:30,180 --> 00:05:32,510 Let's put a breakpoint in use and check. 55 00:05:32,700 --> 00:05:33,810 What will this do? 56 00:05:38,680 --> 00:05:47,300 And I will choose Loubriel select, and now it has stopped the excuse at the big point. 57 00:05:47,770 --> 00:05:52,300 Now let's check everything, let's check the values. 58 00:05:53,020 --> 00:06:03,090 Values is the trinity with all the keys that we have, the clear and all the elements that we have and 59 00:06:03,100 --> 00:06:04,960 gave them EKI also. 60 00:06:06,210 --> 00:06:16,740 So let's get the values of the key is, see, this will be the path that we have chosen, but this is 61 00:06:16,740 --> 00:06:21,030 a string, so we will create a path out of it. 62 00:06:23,160 --> 00:06:25,150 And now this is above. 63 00:06:25,690 --> 00:06:36,330 OK, now let's grab the extensions and this is again in the values, this one, we haven't modified 64 00:06:36,330 --> 00:06:36,570 them. 65 00:06:36,570 --> 00:06:37,740 So it's this one. 66 00:06:40,320 --> 00:06:49,080 Next thing is, we will use our globe, which will get a list of all the files in the US. 67 00:06:49,410 --> 00:06:51,870 So let's check the files now. 68 00:06:52,290 --> 00:06:53,750 This will be a generator. 69 00:06:53,970 --> 00:06:57,390 We will convert it to a list using less. 70 00:06:57,870 --> 00:07:04,950 And now we have a list of all files in those folders as. 71 00:07:06,450 --> 00:07:14,720 So now we can I trade over them and and update our multiline. 72 00:07:15,240 --> 00:07:29,010 So I'll check if files this mean that it's not empty for everything in files, window out to update 73 00:07:29,250 --> 00:07:30,970 an element in the window. 74 00:07:31,020 --> 00:07:35,240 We will use Windu and then we will pass in the key. 75 00:07:35,640 --> 00:07:39,180 The key for the multiline is file. 76 00:07:39,630 --> 00:07:41,010 We will pass it in your. 77 00:07:43,130 --> 00:07:49,520 Files, then we will use the method, since this is a multiline, it have a print method. 78 00:07:50,950 --> 00:07:55,000 Which will update the multi-line with the values that we want to Ockrent. 79 00:07:56,090 --> 00:07:58,970 Now, let's check this, I choose. 80 00:08:01,020 --> 00:08:03,000 The pass the library were in. 81 00:08:05,450 --> 00:08:10,460 And now it had populated the list with all the files. 82 00:08:10,810 --> 00:08:17,360 OK, this is very cool, but we can modify that first. 83 00:08:17,360 --> 00:08:19,570 Let's choose another path. 84 00:08:21,910 --> 00:08:33,970 And it had again repopulated the left, so in order to overcome this, we can clear left before putting 85 00:08:33,970 --> 00:08:35,740 anything in it. 86 00:08:35,740 --> 00:08:42,430 So we will use Windu of files, not a date. 87 00:08:42,880 --> 00:08:46,090 And this will update all the values. 88 00:08:46,330 --> 00:08:51,790 We will give it value argument and then we will pass in an empty string. 89 00:08:52,090 --> 00:08:53,640 Let's check this out. 90 00:08:53,860 --> 00:08:55,040 Choose the library. 91 00:08:55,510 --> 00:08:59,610 OK, let's choose this first. 92 00:09:00,370 --> 00:09:05,840 Now it have cleared the multiline first and then assign it then. 93 00:09:05,930 --> 00:09:15,700 Well this is nice, but I don't like the wrapping here, so I don't want this to be in here. 94 00:09:15,700 --> 00:09:20,080 For example, every rule should be a file by itself. 95 00:09:20,410 --> 00:09:27,790 OK, so we have a couple of options to wrap the first option. 96 00:09:27,790 --> 00:09:31,170 We can give it our parameters in here. 97 00:09:32,870 --> 00:09:44,780 And not widget, dot com, fake rap, equal to none, and which is capital letters. 98 00:09:44,810 --> 00:09:49,720 Let's check this Telek the folder now it had dropped the text. 99 00:09:50,080 --> 00:09:55,140 This is the first option, but I prefer another one. 100 00:09:55,520 --> 00:10:04,130 What I will do is I will calculate the number of characters in each file and then we will set the width 101 00:10:04,460 --> 00:10:10,830 of the multiline to the largest number of characters in a file. 102 00:10:10,850 --> 00:10:13,040 So let's check this first. 103 00:10:13,550 --> 00:10:19,100 Let's get the number of characters in the list of files first. 104 00:10:19,100 --> 00:10:20,970 Let's put a breakpoint in here. 105 00:10:20,990 --> 00:10:22,610 Let's talk about this. 106 00:10:23,160 --> 00:10:24,770 Let's take it a step by step. 107 00:10:26,040 --> 00:10:27,660 I will choose the library. 108 00:10:32,810 --> 00:10:43,430 Now we have a list of files, so we want to trade on each one of them and get the number of characters 109 00:10:43,970 --> 00:10:49,710 in each file to do this, we will use a list comprehension. 110 00:10:50,450 --> 00:10:51,050 We will. 111 00:10:53,150 --> 00:11:03,770 Get X for X in files, and this will play out of them, so we have done nothing, so we will convert 112 00:11:03,770 --> 00:11:05,130 this less to string. 113 00:11:05,600 --> 00:11:16,050 Now we have converted them to strings, and since we have changed, we can get its plans very easily. 114 00:11:16,490 --> 00:11:21,160 Now we have Delane of each file. 115 00:11:21,650 --> 00:11:27,180 I mean, the length of its name to get the max, we will use Max. 116 00:11:27,290 --> 00:11:32,220 This will get us the maximum length of file and all of this. 117 00:11:32,240 --> 00:11:33,950 So I'll copy this. 118 00:11:34,460 --> 00:11:42,650 I'll put it in here and I'll create a variable, all characters equal to what we have calculated. 119 00:11:43,970 --> 00:11:46,940 And then we will use Wendell. 120 00:11:49,720 --> 00:11:53,620 Files not set size. 121 00:11:56,110 --> 00:12:03,760 Then we'll give it parameters size, which we will give a chance, which is a number of characters, 122 00:12:04,360 --> 00:12:12,620 and we can give it none as the other parameters, so it will not change it, which is the high. 123 00:12:12,820 --> 00:12:14,200 Now, let's take this. 124 00:12:15,120 --> 00:12:16,990 Of course, all of these are often. 125 00:12:24,190 --> 00:12:32,620 I'll choose library and now the multiline, I just get to the maximum of the length of the filename. 126 00:12:33,700 --> 00:12:35,290 This is nice. 127 00:12:35,800 --> 00:12:40,720 Let's see what we will do when the destination is populated. 128 00:12:41,410 --> 00:12:49,180 We will need to alert the user if the directory contains some files. 129 00:12:49,750 --> 00:12:58,990 Previously on In the Back of the script, when the destination directory was not empty, we will normally 130 00:12:58,990 --> 00:13:07,270 prompt the user destination does exist and it will be overwritten and then we will check if the user 131 00:13:07,270 --> 00:13:09,400 selected yes or no. 132 00:13:09,850 --> 00:13:12,980 If he selected no, we will get. 133 00:13:13,000 --> 00:13:16,050 Otherwise we will proceed with the packet. 134 00:13:16,330 --> 00:13:23,160 We will do something similar, but we will check if the directory is empty or not. 135 00:13:23,920 --> 00:13:24,210 OK. 136 00:13:25,210 --> 00:13:37,750 So let's first, as if event equals this nation, let's check if I will say this, the nation will equal 137 00:13:37,750 --> 00:13:42,220 to half of the values of this nation. 138 00:13:42,850 --> 00:13:50,590 OK, let's put a break point in here and excuse this and let's see how I would get if the character 139 00:13:50,590 --> 00:13:51,870 is empty or not. 140 00:13:52,740 --> 00:13:58,950 I trust this director, for example, now we they execution's up, let's. 141 00:13:59,750 --> 00:14:02,250 Get this and execute it. 142 00:14:02,930 --> 00:14:13,460 Now let's check a destination that is NASA destination letters Dyer, which will return a generous generator 143 00:14:13,460 --> 00:14:15,650 we can use next this. 144 00:14:15,650 --> 00:14:19,670 Will I trade through the content of the. 145 00:14:20,350 --> 00:14:30,280 Generated, so this means that if we have an empty directly, it will return nothing to implement. 146 00:14:30,280 --> 00:14:39,420 This will use empty will equal to the Etta's dire, then we will get next. 147 00:14:39,730 --> 00:14:44,140 But if it's empty, we will return none. 148 00:14:44,350 --> 00:14:48,670 Then we can check if empty mean. 149 00:14:48,670 --> 00:14:50,580 The directory is not empty. 150 00:14:51,160 --> 00:14:59,880 In this case, we will generate problem or cancel destination contains funds. 151 00:15:02,080 --> 00:15:05,350 If you proceed, it will be. 152 00:15:10,480 --> 00:15:19,000 This will display above a message, but we want to get what button have been pressed, so we will assign 153 00:15:19,000 --> 00:15:29,070 it to a variable and then we will check if we can equals cancel this mean that the users have pressed 154 00:15:29,290 --> 00:15:35,480 the cancel button, this mean that he will not choose this folder. 155 00:15:35,620 --> 00:15:39,370 So we should clear the content of the destination. 156 00:15:40,420 --> 00:15:44,290 To do this, we will use window of this. 157 00:15:44,300 --> 00:15:50,320 The nation, the date value equals an empty string. 158 00:15:50,800 --> 00:15:56,360 OK, now let's talk about this and check what will happen. 159 00:16:01,440 --> 00:16:04,950 I'll choose a folder that contains something, this one. 160 00:16:05,460 --> 00:16:14,870 OK, now destination equals to the folder that we have chosen, we will I trade and check if it's empty. 161 00:16:15,300 --> 00:16:16,470 Actually it's not. 162 00:16:16,950 --> 00:16:18,850 So it has value. 163 00:16:18,900 --> 00:16:23,070 This means that we will enter this statement. 164 00:16:23,340 --> 00:16:29,070 Now, an out of box will appear on the screen destination and contains file. 165 00:16:29,490 --> 00:16:31,620 If you proceed, it will be deleted. 166 00:16:32,040 --> 00:16:34,380 We will press OK, for example. 167 00:16:34,890 --> 00:16:41,110 This means that we will not enter and the program will continue. 168 00:16:41,580 --> 00:16:44,220 Let's do the same thing again. 169 00:16:44,850 --> 00:16:46,320 This time we will. 170 00:16:47,570 --> 00:16:48,870 On cancer. 171 00:16:49,250 --> 00:17:00,170 So we will enter this now, their input is populated with the Foldit, so when we execute Windu update, 172 00:17:00,170 --> 00:17:04,100 it will clear that sickness that build it. 173 00:17:04,700 --> 00:17:05,280 Very nice. 174 00:17:05,300 --> 00:17:14,160 So we have now implement what will happen when this source folder is selected. 175 00:17:14,180 --> 00:17:20,510 And what will happen when the destination folder is selected and we have implemented what will happen 176 00:17:20,510 --> 00:17:21,850 when we click on Exit. 177 00:17:22,460 --> 00:17:27,680 The remaining thing is to implement what will happen when we come back.
