[Gambas-user] Combobox, old Auto-list-width-behaviour, I'm confused

[ub2 at gmx.ch]

Dear Benoit


Thanks a lot for your info. Unfortunately I'm confused:

- There won't be a kind of
-- cbo.ListAutoWidthAdjust = true/false
-- cbo.ListWidth = [0...]
-- cbo...?
property in future. Right ?

- GianLuigi's todays recommendation neither (27.05.22 um 11:58) ?
   ...
   "Benoit I think you should change W -= Style.FrameWidth * 2 to 
something like W = gvwPopup.Columns[0].Width + ... "
   ...

- When Xubuntu switches to Wayland following workaround will fail:

Public Sub Cbo_ListAutoFitSize_Enter()
     FrmCboListAkt.Form_Open(Cbo_ListAutoFitSize)
End

And then FrmCboListAkt acting like a Popup List:
- Placing FrmCboListAkt itself "just underneath" Cbo_ListAutoFitSize
- Showing Cbo_ListAutoFitSize.List in a tableview
- detecting user selected line
- then sending Column0 of selected line back to Cbo_ListAutoFitSize.text
- and then FrmCboListAk.close


So, what do you recommend me to do with cbo's representing for example:
a) "a user selected option" like:
Opt	Explanation:			Further Info:
1	User description of Option 1	...
2	User description of Option 2	...
3	User description of Option 3	...
...

	or

b) "a user choice of Backup-Paths":
Opt:	Backup-Path:			FreeGB
1	/.../.../(long Path to)/...	123
2	URL.....			224
3	/.../.../...			0
.	...				.


Please apologize if I got sth completely wrong.

Thank you for your patience. Have a nice WE.
(I'll check email tomorrow and Monday)
