Summary

Dark theme issues

Type             : Bug
Priority         : Medium
Gambas version   : Master
Product          : GUI components


Description
-----------

My app has a custom (light) background.
when desktop is dark theme i have various problems.

1st as Label text and other text was light i set the Form.Foreground to Black to rectify.
Now labels show black text okay but still a few other problems with controls...

Buttons look okay as they are using dark theme BG and FG color. (not a problem, this is fine)

ComboBoxes are using dark theme BG but my now set black Form.Foreground not dark theme foreground (I think they should color the same as buttons)

If i manually set combobox BG and FG color the combobox menu BG does not match but FG does.
it uses the theme BG but my set FG color

Checkboxes are "not" using my set form.foreground text color (i think they should as they have no background like buttons)

MenuButton.Background and foreground cannot be altered at all with light or dark theme
It's just what it wants to be and not changeable.


I will attach the app if you like so you can see the color issues...

Many thanks
Bruce
