[CentralOH] Tkinter Checkbutton

[Mark Erbaugh]

I would like to place some Tkinter Checkbutton's on a Canvas. When I use a Frame and the Pack geometry manager, it knows the appropriate height of the Checkbutton so that that it can align them properly.  Is there a way for me to determine the height of a Checkbutton when placing it on a canvas?  I tried using the Checkbutton's font height, but the indicator (checkmark box) is taller.

Thanks,
Mark
