FLTK DnD support works quite reliably in FLTK. You have to derive your
own widget and respond to FL_DND_ENTER, FL_DND_LEAVE and FL_DND_RELEASE
as well as FL_PASTE:
to be more concrete:
class mywidget: public Fl_Box
{
public:
mywidget(int X, int Y, int W, int H, const char*
L=""):Fl_Box(X,Y,W,H,L) {}
int handle(int e)
{ switch(e)
{ case FL_DND_ENTER: {/*do something on enter*/ return(1);} break;
case FL_DND_LEAVE: {/*do something on leave*/ return(1);} break;
case FL_DND_DRAG: {/*do something while user is dragging mouse
with dnd data inside the widget*/ return(1);} break;
case FL_DND_RELEASE: {/*accept dropping -> results will be
pasted as an FL_PASTE event*/ return(1);} break;
case FL_PASTE: {/* here is the dnd-data in Fl::event_text() and
its length Fl::event_length() */ return(1);} break;
default: return(Fl_Box::handle(e));
}
}
};
You will find more information on events at

I hope this helps.
