I much prefer the stronger contrast of using the FL_SELECTION_COLOR in FLTK 1.3:

I took a look at Fl_Menu_Item::draw() in Fl_Menu.cxx but it didn't seem clear how to customize a Fl_Menu_Bar to get the same effect.

Using test/editor.cxx as an example, I can add app_menu_bar->box(FL_FLAT_BOX); to replace the up box with a flat box, but I can't figure out how to always use FL_SELECTION_COLOR as the selected background color. (app_menu_bar->selection_color(FL_SELECTION_COLOR); as no affect and app_menu_bar->color(FL_SELECTION_COLOR); makes every non-selected menu item use the selection color.)

I also think the new style of the submenu arrows is a bit exaggerated:

And I think the more modest look of FLTK 1.3 arrows was more appropriate:

Is it possible to customize this?

Thanks for any advice.
