Or maybe:
/** Returns a pointer to the root parent widget.
Usually this is a Fl_Window.
\retval NULL if the widget has no root parent
*/
Fl_Group* parent_root() const;
Fl_Group* Fl_Widget::parent_root() const {
Fl_Group *myparent = parent();
while(myparent) {
//if the parent parent is null
//we consider it the root
if(!myparent->parent()) return myparent;
myparent = myparent->parent();
}
return NULL;
}
