Re: Sub form issues.

That solution works great, thanks.

The reason I don't create the sub form with the connection to the
parrent is because in Qt C++ doing so causes the sub form to be embedded
in the parent form rather then a new popup form like a dialog.

Is there a better way? Perl should clean up the garbage when it is
done. 
Is there a destructor for Object Perl? Like 
delete(this->{SubForm});
