Are you using a glCanvas object? I was under the impression that this
problem had been fixed, but I had problems some time ago with deleting
Forms with glCanvases. Here's the hack I use:
void destroy_form( FL_FORM *form )
{
if ( form ) {
void *dui = form->fdui;
FL_OBJECT *obj = form->first;
/*
* This hack necessary because it appears that the cleanup
* routine is otherwise called after the window is destroyed!
*/
do
if ( ( obj->objclass == FL_CANVAS ) ||
( obj->objclass == FL_GLCANVAS ) )
fl_hide_object( obj );
while ( obj = obj->next );
fl_hide_form( form );
fl_free_form( form );
free( dui );
}
}
