Closing tkinter on button press

[blendmo]

New to tkinter. Trying to destroy() the window on a button event. Something like this:

Code: Select all

class TestWindow(Frame):
    def __init__(self):
        # set the title of the window
        Frame.__init__(self)
        self.pack(expand=YES, fill=BOTH)
        self.master.title('Test Custom Input')

        # the button that do stuff and close window
        Button(
            text="Click Me!",
            width=25,
            height=5,
            command=self.conclude
            ).pack()
            
    def conclude(self):
            self.destroy()

Utilizing the standard foreign window:

Code: Select all

def Do(Environment):
    # just show the dialog
    Wnd = TestWindow()
    App.Do( Environment, 'StartForeignWindow', { 'WindowHandle': int(Wnd.winfo_id()) } )
    Wnd.mainloop()
    App.Do( Environment, 'StartForeignWindow', { 'WindowHandle': 0 } )

Instead of the window closing and returning control to the Do function, it just puts the window behind PSP. However if I click the [X] button to close, it does what I expect. What am I missing?

Destroy the master.

Code: Select all

    def conclude(self):
            self.master.destroy()
