but you put the gtk_file_selection widget within a gtk_window ?
btw, the same is happen here with forms
function TCustomForm.ShowModal: guint;
begin
gtk_window_set_modal( PGtkWindow( FComponent), True);
//set_modal( PGtkWindow( FComponent)^, 1);
gtk_widget_show( FComponent);
end;

I think is too complicated.
'if MyOpenDialog.Execute then' is more simple (and delphi compatible)
one solution must be that Execute connect signals and wait in a loop
until a signal from the gtk_file_selection come (ok, cancel).
Hmmm, I think this is the cleaner solution ...
In the create of OpenDialog we connect signal (used internally)
and in Destroy we disconnect the signals.
In Execute we wait in a loop a signal, and voilé, showmodal and
delphi compatible.
(I'm thinking in what happens if the user close the window :)
