I'm afraid, FLUID does not offer such automatic solution (at least I don't
know one), the "delete window" has to be typed in by hand.
BTW: If a FLUID made class (widget class or wrapper class) has a function
like
void create_dialog() { dialogwin = new Fl_Window(...); }
which creates a top level window *optionally outside* of the Ctor, then also
the NULL initialization
dialogwin = NULL;
has to be typed in by hand somewhere in the Ctor or an init() function
to avoid crashes of the "delete dialogwin" in the Dtor in case the
window was not created.
