Hiding/showing Tkinter.Canvas items

[Peter Otten]

Before I start moving them into dark corners of the canvas - is there a way
to hide/show Tkinter canvas items without having to maintain their original
position externally? All I've found so far is sortvisu.py in the demos that
toggles their coordinates between (0,0,0,0) and the real position/size. 

Thanks,
Peter
