CodenameOne - change color of checkbox in theme

Question

I'm using the 'Blue Flat' theme in a cn1 project, and the checkboxes in a MultiButton component (I suppose following the Button text color) are completely white, making them invisible on a white background. I've tried changing their foreground color in the theme (in the GUI Builder theme tab), I tried replacing the theme files with checkboxes of a darker shade, but nothing seems to affect it.

How can I make the MultiButton checkbox a different color?

Answer 1

The blue theme customizes the checkbox image theme constant which you can remove at which case it should derive theme colors:

Just select the constants tab in the theme and remove the ones relevant to the checkbox.
