Hi,
If you are going to run your program on Linux/Unix, you can use DBus

True; this would be quite challenging to achieve as Fl_Menu_Item
provides only plain draw().
For the similar reason (to add icons support inside menu items) I had
to literally 'fork' the whole menu hierarchy :S

First you need to assign callback to desired Fl_Menu_Item, whose colors
you are going to change. From callback you can access Fl_Menu_Bar and by
using mvalue() member, you can access to selected item; from there you
can change label color, background and etc.
Here is example:

Actually Fl::set_font(FL_HELVETICA, "font name") is better, since
