but I won't know if the GUI is presented yet or not, will I?

What is your use-case for an

onLoad

event?

I plan on loading some things on startup, and I'd rather do it after the GUI is displayed, so I don't accidentally bog down display of the gui

so that the application is still responsive

I would display a "loading" dialog, or whatever to indicate that it's doing work

Ahha, you should use a Preloader - https://docs.oracle.com/javase/8/docs/technotes/guides/deploy/preloaders.html

bingo

@beepdog I think you're looking for the onDock() function on the main View of your TornadoFX application. In pure JavaFX terms, this is the OnShown handler added to the main Stage. All of the UI controls are available so you can interact with a progress bar while your data asynchronously loads.

That'd be it also

Although a Preloader would also work

Preloader is probably "more correct" but an onDock would let me interact with a gui, and get the same job done

I haven't used a preloader for a few years. One of the big drawbacks is that it's not as tightly integrated with your class as an onDock(). Also, I found the "hooks" of preloader a limited.

onDock() is an unfortunate name because most of us aren't docking anything.

gotcha

that's why I was expecting an "onLoad" or "onPaint" or something that tells me my GUI is done

works for me

thanks!

I agree on not using preloaders. They have a number of other limitations as well (you can't as easily show progress for example). I usually just load a quick loading view to start and swap it out for the main scene when ready.

@carlw I don't really understand. How do I specify priority? And once I've done so, what exactly will be the effect?

can you post some code showing the layout?

A file was commented on

the effect is that the extra space is taken up by the specified component (ex, stretching a table to fill a window)

Also of note: the alignment doesn't put the widget

*on the bottom of the top or the top of the center...they change the horizontal alignment but not the vertical alignment

(The Widgets are fragments)

this post has some code that uses priority. there's a cleaner tornadofx way to set the priority w. hboxConstraints{} https://courses.bekwam.net/public_tutorials/bkcourse_tornadofx_dragging.html

this has the syntax for prefWidth and prefHeight https://courses.bekwam.net/public_tutorials/bkcourse_backgroundapp_kotlin.html

Thanks, will look into that.

Can you pass arguments to a view/fragment?

***yes, you can
