Sure - a lot of widgets don't show much difference in that regard, so it often doesn't really show up. But a widget that has a lot of "open background space", like a group for example, it will matter. The fancy slider widgets are a bit of a special case in that they have a lot of "open space" inside the bounds of an otherwise solid widget, so they manifest the "feature" more visibly than some... > Fair enough.

Hmm, depends on what you mean by easy; For now, I'd suggest either of two options: 1: Derive my own group from Fl_Group and then over ride its colour methods to walk the list of its children and set them too. 2: Derive my own slider widget and have it (probably in its draw() method) check the background colour of its parent and use that. I think (1) might be more capable, since it ought to work for any contained widget. But (2) is probably simpler, if you only have to deal with slider widgets... The other option, at some indeterminate point in the (possibly distant) future, is that the styles and themes functions land (in fltk3) and that gives us the means to "magically" change all the child widgets in a group in one swoop...
