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:
static void color_cb(Fl_Widget *w, void*) {
Fl_Menu_Bar *bar = (Fl_Menu_Bar*)w;
if(!bar->mvalue()) return;
Fl_Menu_Item *self = (Fl_Menu_Item*)bar->mvalue();
self->labelcolor(FL_RED);
}
// your Fl_Menu_Item table:
static Fl_Menu_Item table[] = {
{"&File", 0,0,0,FL_SUBMENU},
{"To red", 0, color_cb},
{0}
};
