And welcome to part six of our key V tutorial in this video, we're going to be finishing up our TV chat application and then, uh, testing it made sure it all works.

And then in the next video, we'll actually be packed.

Well, we'll be going over packaging, and we'll all at least go over.

You know how you would do it on Windows and how you can do it on Android.

Uh, mayor may not cover IOS and other things we will see.

So Ah, basically the crux of all the things that we have to change here are going to be in our chat page.

So as soon as I find shat Page here we are.

So we need to change the send message bit.

Um, and then we also want to add a couple more things, even tore, innit?

So the first thing we're gonna do is window.

We're gonna adopt bind, and we're going to say on key down equals self dot on underscore key.

Basically what that's gonna before is so we can bind the enter key to also send a message.

Click it, you know, every chat up you hit enter and it sends a message.

All right, so once we've done that, uh, now what we want to do is we are going to clock dot sh Edgell.

Uh, once I am, we're going to schedule self dot focus, underscore text, underscore input.

We'll do that in one second, and then we will.

Client dot Start on her score listening and then self dot Incoming underscore message and show error.

Okay, so now let's go ahead in handle for that on key down time.

Key self dot Send underscore message, and then we'll pass none there, Uh, because son messages Expecting something.

Uh, now, now what do we do so we could cut?

So rather than printing send messages useful is that once was we're gonna say message equals self dot new underscore message dot text that is core responding to this, right, our text input.

So again, that's just always able to be pulled.

And we're just gonna grab whatever is in there any time someone hits the enter key or clicks on that button.

So either way, they hit the enter key it run, send message, or if they click on that button, it runs.

So we grab the message and then immediately let's self dot new message dot ms dot text.

We're gonna set that to be empty because we want to empty out once they send the message that we don't want that message to remain in that box.

Ah, so long as there is a message if message we're gonna say self dot history dot update shat history hiss story.

Um, I suppose I'll type it and we'll talk about it, so it's gonna be in every string.

And then we're going to say the color is equal to D D 2020 and so the are user name and then other user names are gonna be different colors.

So dd 2020 and then we're gonna say, uh, chat app dot connect page dot user name.

So this is just and then dot tax no, forget dot text.

Uh, this is just gonna be your username, right?

So we're just gonna grab your user name from, uh, that original log in page.

Then we're gonna close off our color tags, so slash color are slashed color, and then what we're going to dio is, um, just dio a greater than symbol there.

And then whatever the message is, eso using F strings will just format that in their beautiful cool.

So once we've done that, we want to send that message out to everybody else so we see our message, but now you need everybody else to see our message.

So we're going to use the socket client and where schools a socket client us send a message, and it's gonna handle all the socket stuff for us.

Uh, now, what we want to dio is refocus on that input field.

So we're gonna say clock clock dot schedule, uh, once.

And we'll just do that really quickly after they've hit the enter key.

Hopefully, this is not like a super fast user.

Ah, and we could actually slow people down.

I'm I'm a totally ah person who, like, sends a message and then hit center and then continue.

Like, rather than make all one big message, I make, like, four lines.

Um, we could really slow people down this way anyway.

But we won't, so All right, once we've done that, um, now we're gonna need to focus text input.

Well, we're gonna need that to be a method.

Parameter self dot New underscore message dot Focus is equal to true.

And then finally, um, we need to get any new messages.

So we're gonna say define, uh, incoming message self.

So self dot history dot update chat history.

Uh, with an F string and again, We're gonna say color, and this time we're going to give it a 20 dd 20 and then it will be whatever that user name waas and then slash color And then, like before the message.

Let's just go ahead and run and see what happens.

Well, go ahead and connect locally because we're running locally.

Okay, so we're definitely Oh, you know what?
