[Tkinter-discuss] Toplevel - failure to understand it

[gegard]

I have a Tkinter app that works for me until I use Toplevel to add a title.
My efforts to use Toplevel have confused me, bringing an additional
unwelcome blank window that I don't understand how to manage.

The question is simply "how do I confer Toplevel methods to a top level
PanedWindow and still have the application run in a single window?"

Thank you for any direct help or pointers to code that works that I could
understand.

Regards,
Geoff

        self.left = Label(self.mainpane, text=self.idtext+"left pane")

    tk1 = TkApp(idtext="App1 ")

Alternative main ...

if __name__ == '__main__':
    # A window that works but comes with an additional blank window
    tk2 = Toplevel()
    tk2.title("Title2")
    tk3 = TkApp(tk2, "App2 ")
    # comment next line out when using IDLE
    #mainloop()
