wierd tkinter window issue

[Scott Hathaway]

I have a window that I call overridedirect(1) on to remove the titlebar on
Windows.  Then, I have a button that minimizes the app.  To minimize by
code, I have to call overridedirect(0) and then iconify() to minimize.

Then, what event is called when the window is maximized again, so that I can
remove the titlebar again with overridedirect(1)?

I have tried Activate, Enter, and FocusIn.

TIA,
Scott
