00:00:00,540 --> 00:00:01,980

Well, hello, dear friends.



2

00:00:02,430 --> 00:00:03,540

I'm so glad you're back.



3

00:00:03,990 --> 00:00:08,100

Because right now, we're going to implement this back button functionality.



4

00:00:09,180 --> 00:00:10,140

So we'll dig in.



5

00:00:13,190 --> 00:00:18,860

Now, first of all, let's see what we want to do with the back button, and that way you'll get how



6

00:00:18,860 --> 00:00:19,310

to do it.



7

00:00:20,700 --> 00:00:28,110

So if we press manage employee and we press back, we should be able to hide this window and display



8

00:00:28,110 --> 00:00:29,160

the main window again.



9

00:00:29,160 --> 00:00:29,460

Right.



10

00:00:30,360 --> 00:00:31,290

Sounds simple enough.



11

00:00:32,310 --> 00:00:36,900

So let's go to the manager employees and add some code.



12

00:00:39,650 --> 00:00:48,230

All right, so we will have a successful back button when we use self dot UI, dot back button.



13

00:00:49,550 --> 00:00:51,350

Now, I'm sure you already know how to do that.



14

00:00:52,430 --> 00:00:56,060

Dot clicked, dot connect itself.



15

00:00:56,060 --> 00:00:58,370

Dot back button clicked.



16

00:01:01,840 --> 00:01:04,010

Of course, you can do it how you want to.



17

00:01:04,490 --> 00:01:06,560

So now let's define a function.



18

00:01:12,740 --> 00:01:15,920

Def back button clicked self.



19

00:01:19,890 --> 00:01:21,390

Self-taught hide.



20

00:01:23,580 --> 00:01:30,120

All right, cool, so now what we want to do is hide this window so that it's hidden and it shows a



21

00:01:30,120 --> 00:01:33,120

window, which is actually its parent.



22

00:01:34,400 --> 00:01:35,180

Self-taught.



23

00:01:35,390 --> 00:01:37,940

Main menu dots show.



24

00:01:39,860 --> 00:01:42,950

And here we have it stored in this variable here.



25

00:01:44,400 --> 00:01:47,160

That seems to be pretty OK.



26

00:01:47,370 --> 00:01:48,900

Why don't we test it out, in fact?



27

00:01:49,350 --> 00:01:50,730

So press back.



28

00:01:51,570 --> 00:01:52,920

Yeah, you see how that works.



29

00:01:54,570 --> 00:01:57,840

So now we've got to do the same thing for view chart menu.



30

00:01:59,040 --> 00:02:08,190

So let's go to charts and we have to type basically the same code, self-taught UI dot back button,



31

00:02:08,190 --> 00:02:13,920

dot clicked dot connect itself, dot back button clicked.



32

00:02:18,560 --> 00:02:20,200

And then we define our function.



33

00:02:21,290 --> 00:02:23,780

Def back button clicked self.



34

00:02:27,640 --> 00:02:28,840

Self-taught hide.



35

00:02:35,800 --> 00:02:38,620

Self doubt, main menu, dot show.



36

00:02:42,260 --> 00:02:43,100

OK, let's see.



37

00:02:43,910 --> 00:02:50,000

Well, we don't have the back button because we forgot to rename it when we created the way through



38

00:02:50,000 --> 00:02:51,650

the designer, so.



39

00:02:51,970 --> 00:02:53,600

So let's run the program.



40

00:02:55,590 --> 00:02:58,080

Excellency, your charts go back.



41

00:02:59,930 --> 00:03:01,460

And this one also works.



42

00:03:04,000 --> 00:03:05,620

Very good, so that's it for now.



43

00:03:05,650 --> 00:03:07,900

We've implemented the back button functionality.



44

00:03:08,760 --> 00:03:11,280

And in our next lesson, we're going to continue to code.



45

00:03:11,490 --> 00:03:12,540

So I want to see you there.



46

00:03:12,910 --> 00:03:14,130

I'll see in the next video.
