Hi Guilherme,
Thanks for the reply. That seems to solve the error up to a point but I
still get:
TclError: can't invoke "toplevel" command: application has been destroyed
if I destroy my application main window, which is at the top of the
hierarchy so to speak. Furthermore, if I pass self.master to all of my child
windows, they remain visible when the windows which create them are
destroyed and I'd rather not have it like that. For example, in one scenario
the user is supposed to change the application settings through these child
windows and they remain visible even though the dialog which is supposed to
apply the settings have been destroyed (it's also the dialog which launches
these child dialogs).
Is there a way to completely block the window controls, ie. the close button
at the top corner of a window?
