Examples: could an example be added for LibUI.new_scrolling_area? about libui HOT 5 OPEN

I found it works on kotlin:

Guess now the key is to understand the kotlin code. :)

If it works then perhaps it could be added towards control_gallery.rb ? Since the latter already
contains a LOT of demo-examples.

Hi @rubyFeedback

I think LibUI.new_scrolling_area is to create an area with scroll bars. It is not a widget container.

The kotlin example you gave is just a multiline_entry.

I think what you really want is Table or append/delete of hbox.

In Ruby/Tk, you can use BWidget in this way.

require 'tk'
require 'tkextlib/bwidget'

root = TkRoot.new

sw = Tk::BWidget::ScrolledWindow.new(root)
sf = Tk::BWidget::ScrollableFrame.new(sw, constrainedwidth: true)
sw.set_widget(sf)
vf = sf.get_frame
vf.configure(bg: :white, borderwidth: 1, relief: :groove)

10.times do |i|
  TkButton.new(vf, text: "button #{i}").pack
  TkLabel.new(vf, text: "label #{i}").pack
end

sw.pack(fill: :both, expand: true)

Tk.mainloop

I already provide an Ruby example of scrolling_area in Glimmer DSL for LibUI

(sorry, I didn't see this issue before as I was very busy with other stuff the last two months and had unwatched LibUI except for releases to keep myself focused on my tasks, but I just re-enabled full watching of LibUI to stay informed of issues in case I could help)

Code: https://github.com/AndyObtiva/glimmer-dsl-libui/blob/master/examples/basic_scrolling_area.rb

BTW, you can only control the scrolling programmatically on Mac, but not Windows and Linux (seems like a bug in C libui). But, you can still scroll the area manually on all platforms at least.

Otherwise, you cannot put anything in a scrolling area (like labels and buttons), yet only area content like path shapes. That said, by building area-based custom controls, you can then add your own (custom) flavors of label and button inside a scrolling area, and thus achieve your goal anyways.

If you need help in programming your app with scrolling_area, hit me up about it with an Issue request in Glimmer DSL for LibUI. I'd be happy to help you implement it.

Cheers!
