Mickael,
I might be off base on this observation, but if I recall correctly (from
getting Oomph things to behave correctly with dark theme), if one
subclasses Composite, your subclass is no longer styled as a composite.
And there's no simple way to mark it the instance so that it's styled
according to some existing style definition. I.e., a feature to "please
treat this instance as a composite" would definitely have been helpful.
It was also my observation that trying to set colors during construction
is kind of a losing battle because the styling comes back later and
changes the colors. All the theme support is generally super complicated...
Regards,
Ed

Hi,
You can directly ask this to the platform-ui-dev mailing-list. This e4
one isn't really relevant now.
About your custom widget, I guess by Custom you mean that you're
actually taking care of some parts of their drawing? If so, then I
believe it's up to you in your drawing routines to read the widget
style and to choose the right colors for background/foreground
accordingly. One possibility if you wish really dynamic results is
that instead of reading the style, you simply rely on the background
color of the parent composite, so you don't have to deal with CSS and
your widget would be portable in any composite and integrate well in
it without tweak
HTH.
