Maybe I will implement it to be delphi compat
but first must test it on all platforms. Also I would like to
have property inside TCustomForm which can
change behaviour of ShowModal() when Hide()
is called.
1.I like current implementation because you
can have "alive" form to show again and again.
2.Delphi implementation just hides form but
stays in modal loop, and other forms are accessible - I don't
like this solution but I respect other ppl needs.
So what property name could be goodfor such
behaviour ?
HideModalBehaviour = hmbLazarus (default),
hmbDelphi( Delphi compatibile) ?
I don't thing it's worth a property.
1) Close can always be used for current behaviour.
2) Hide and the setting ModalResult can be used too
