Progress widget with themes

[benjaminaarsen]

Hello I noticed when using themes the Progress widget does not work. The border of it shows but it does not show color inside of it. Changing the selection color and calling redraw() etcetera does not work. Without themes the progress widget works as expected so i think the issue is not with my own code.

It's an issue with FLTK's Fl_Progress and its default choice of boxtype.
You can try setting .set_frame(FrameType::RFlatBox); and see if that changes anything.
