According to man wm:
(...) the return value is a Tcl list containing four elements
corresponding to the current baseWidth, baseHeight, widthInc, and
heightInc; if window is not currently gridded, then an empty string is
returned.
So you should be able to check the window's "grid state" easily with
wm_grid(), if it's None, the window is not gridded:
>>> root = Tk()
>>> print root.wm_grid()
None
>>> print root.wm_grid(100, 100, 10, 10)
None
>>> print root.wm_grid()
(100, 100, 10, 10)
>>>
Regards
Michael
