Needed basic widgets about druid HOT 10 OPEN

I would like to suggest two more advanced widgets - a table and a tree.
(eg GtkTable and GtkTreeView)
These widgets are both pretty ubiquitous in non-trivial real world applications.

Bumping this with a progress report.

With caveats, here's what is functional right now:

• Align
• Button
• Checkbox
• Flex
• Label (single line)
• Padding
• Progress Bar
• Radio button (@futurepaul, #150)
• Scroll
• SizedBox
• Slider
• Textbox (single line)
• Container (@zaynetro, #148)
• List (@raphlinus)

Other basic widgets / extended functionality I believe we need:

• Combo Box
• Dropdown List
• Dropdown Menu
• Multiline Label
• Multiline Textbox

What else do we need for a minimum widget set? I'm especially interested in anything Runebender-motivated.

I've got a table in progress at. https://github.com/rjwittams/druid_table

Rearchitecture seems to go with the territory, Flutter rearchitected their scrolling a year or so ago. It's pretty complicated under the hood. I'm personally leaning towards doing the simplest thing (eagerly instantiating the children) and then figuring out where that falls short.

Knob and slider

Is a scrollable view the sort of thing that would be a widget? That's a high priority feature for me, and I'd like to help on it if possible, but I don't know exactly where in the stack that's going to be implemented.

from druid.

Yes, it's in scope. However, scrolling is invariably one of the more complex architectural pieces of UI toolkit design. Does it try to instantiate the child widgets lazily? Asynchronously? Part of it depends on the expected scale. I need to do some design work.

This will in fact be a major priority soon in the font editor, because of the scrolling glyph list (on the order of 60k glyphs for a CJK font).

I'm not sure if this correlates to how druid is designed, but I think a big part of the React Native rearchitecture is about making scrolling more synchronous.

Anyway, look forward to your design work!

Maybe a ToggleButton? Or would this be something the normal Button could be expanded to do? Or could this be implemented by re-styling a checkbox?
How granular and composable do widgets need to be? I played with QT-Quick some time ago and was quite impressed how flexible and stylable you could make a small collection of very simple composable widgets. Not sure if and how this would work in Rust though.

I've lapsed in keeping this updated, we actually have a toggle widget now!
