Hi all,

I just wanted to ask if anyone has been able to programatically shrink or expand a Frame widget by setting it's height. I have this....

self.height = self.frame.winfo_reqheight() for a in range(self.height, 0, -1): self.frame.configure(height=str(a)) self.update_idletasks() time.sleep(0.1)

But it doesn't work! If I set the time.sleep to 1 second the widget flashes (every second) but doesn't shrink.

The frame widget is packed (with fill and expand set) perhaps this is interfering (I have tried changing the packing options to no avail!

I googled for shrinking Tk Frame widget - and got a few hits but mostly links for other widget sets (Tix, etc) *I* am restricted to pure Tkinter widgets

After more goog'ling pack_propagate(0) ...
