The normal FLTK way is something like "the other way around". A widget that
gets
an FL_ENTER event must return 1 on this event in its handle() method to become
the Fl::belowmouse() widget. Then it will also get FL_MOVE and FL_LEAVE events.
Maybe this is all you need.
Fl::belowmouse() will tell you, which widget is the current "belowmouse" widget
(but this can also be NULL). But this will only work, if your widget's event
handling does, what I described above.
If you want to know, which widget is currently under the mouse pointer at any
given time, then you would need to walk the widget tree yourself and check
every
widget (group) recursively (or you need a table of all relevant widgets for
this
check).
