[Tkinter-discuss] What's the point of Toplevel.wait_window?

[Geoff Bache]

Hi all,

I'm struggling to understand what the wait_window method on
Tkinter.Toplevel objects actually achieves.

It seemed on the surface like it would make the dialog modal, but it
doesn't do that. The "grab_set" method achieves that.

I realise that it starts some kind of local wait loop but I can't
actually discern any external effect from calling it.

Regards,
