Thats right, I remember reading about that now.

so your way (roll your own) might be the best way

once you have a testable version, I would love to test it

currently in my photo thingy I can only select one (poor man;s solution by using the onMouseAction

Actually, it's not that much code, because there are base classes that handle almost everything but the selection model implementation. Mine is a bit naive for now, and the complexity will be much higher if we're to support dynamic changing of all the properties (lots and lots of listeners with weak refs are needed)

@ron OK, I'll let you know.

cool

currently I have implemented drag and drop (without background changing)

I think I will just make two css classes for that and use the addClass and removeClass

OK, I'll log off and continue to play with this thing. Back later!

I keep being amazed how little code you need with kotlin

ok

Yes! Selection is working, with pseudo classes as well. I'm kind of amazed of how good job they have done when it comes to reusability for virtualized controls and cell implementations. Next: Multiple selection support.

in a treeview adding a node, what is the best way to refresh the tree?

clear and run populate again?

@User uploaded a file: Multiple Selection in DataGrid

@ron Either that, or add it manually at the location you want it in.

Multiple selection is working 🙂

yeah just looked at the video, awesome stuff @edvin you are becoming the kotlinfx god of gods

Haha 🙂 This grid was a good idea! I've learned a lot about JavaFX internals now.

Taking a break, continuing tomorrow 🙂

@edvin: How do I get the

TestStylesheet

(set in

tornadofx.Stylesheet

) from interfering with other tests? it makes all the labels bold in test apps.

@Ruckus Sorry, my bad! I removed it now, I just used it while I was creating the ServiceLoader support 🙂

Sounds good.

🙂

Man, I'm struggling with focus models/anchors etc in conjunction with multiple selections. I can't fathom why this thing is so complex..

This makes range selection completely unreliable. Everything else seems to be working great though.

What exactly are you trying to accomplish?

It seems something called anchor is interfering with my focusedIndex. Somehow the anchor makes the CellBehaviorBase augments the list of cells that should be selected. So most probably I just need to understand what "anchor" means and implement it properly.

@thomasnield When you shift-click to select a range of cells I end up with selecting other cells than I expected.
