well, my first question, on re-reading your original message and
noticing that the widget in question in a canvas is what do you mean
by "all drawing"? canvas items update themselves at the right time,
and they are placed there generally in response to other events (mouse
button events, etc.)

putting a canvas item onto the canvas isn't "drawing". by "drawing" i
meant using functions that ultimately attempt to render
lines,rectangles,pixmaps etc. 

you'll need to explain better what you're doing. if its just resizing
canvas items when the canvas size changes, you can do all that from
the size allocate event no problem, because that doesn't cause any
drawing to take place at that exact moment in time.
