Re: [Pythoncard-users] how to trigger on_closefield for the focused

[Bernie H. <ber...@ut...>]

Hi Brad,=20

All windows have an OnClose() method:

It derails any closing event =AD so be sure to have a self.Destroy a the end =
=AD
in the middle just stick in what you want.

Try this:
    def OnClose(self, event):
        dlg =3D wxMessageDialog(self, "Would you like to save before you
close?", "Hmmm....", wxYES_NO)
        if (dlg.ShowModal() =3D=3D wxID_YES):
            self.doSave(event)
        self.Destroy()
