And the volume of data that business frontends have to display and work with. I heard that is not fun to do with JS.

Hehe.. can you say memory leak? 🙂

I think we're in a good place with JavaFX, maybe especially because it's not moving so fast. We've added a lot of suger on top with TornadoFX, and at least for me that has made UI development fun again. And more importantly, the UI code I write these days is maintainable and easy to refactor.

@edvin it's a layer of innovation and flexibility on top of something static and stable, which is wild thing to achieve.

I really hope we get to show what we've built at JavaOne 🙂

@edvin I was going to tell you that I heard some folks ranting about JavaOne not being about "Java" anymore, which I suppose is a good thing for Kotlin and TornadoFX

Maisen is back from New York on Saturday, so come next week I will have more time in front of the computer again. Planning to do screencasts a little more regularly. I miss it.

@thomasnield Java is certainly more than Java the language 🙂

@edvin yes, the JVM in my opinion is where the real value is at, hence why Oracle seems to be receptive to Kotlin (at least that's what I noticed on Twitter).

I can’t find the interview with Gosling about 10 years ago where he mentioned he built Java so he can build more languages on top of it. But he never got around to it.

Cool. It's incredible how extensible the JVM is. One of the finest pieces of software ever made, especially considering how old it is.

This is pretty apt

I'm thinking about doing a screencast, but I don't think the Commands are what I should do. I'm not quite sure where they fit in yet, so I don't want them to come across as a best practice quite yet. Any suggestions for a helpful screencast?

Have you done one on

Wizard

?

@kastork Yes he did.

@edvin Maybe something with

Scopes

and

ViewModel

Scopes and ViewModel.. I think I have done some, but maybe nothing that shows the current best practice. Looking..

@edvin Yes you did already a Master/Detail one ...

Right.. Hm..

I could do "Login Screen" perhaps. I know some have struggled with finding a good solution for that.

Maybe you could show of some complex navigation with the

Workspace

with nested

Views

I'd like to do a mainstream one first. My channel have been quiet for a while, so I want to show something that would interest as many viewers as possible.

@nimakro But that's a good point. I think I will show how to delegate the workspace buttons to nested views. (In an upcoming one, not the first)

There are several strategies for that, both automatic and manual.

@edvin Sounds good.

If you want to do the Login Screen you could also use your

GitHubBrowser

project maybe update it to the latest changes of tornadoFx, so people can see how the project evolved... And you have a login screen in that project 😉

Haha, I'm actually looking at the GitHub Browser project right now.

The Command pattern might be a good fit for this actually, because it automatically takes care of running the action in the background as well as disabling the button while it's running.

I will update the project after the screencast then.

I looked at the login functionality in GitHub browser. It is pretty easy to follow, and works well. There is one thing though. The UserModel is injected and available in the same scope as the logged in screens. That means that even though you cannot access the logged in screens before you have actually logged in, those screens are going to see the UserModel changing values as you type in the login screen. That feels wrong to me. I think it should use a separate scope for the LoginScreen and then update the UserModel in the actual logged in parts of the application after a successful login. I think that is a more sound, although slightly more involved process. Maybe I can find a way to show both. Start with the way it's done in the GitHub demo and then evolve that into the better version perhaps.
