DrawingTools AttributeError

[jtanadi]

I was getting AttributeErrors & narrowed it down to the "viewDidChangeGlyph" observer. Line 113 in myDrawCallback is one of the line() drawing functions.

I think that observer doesn't like being used to draw for some reason... something like this seems to work better (also then you don't have to redefine self.g every time the glyph window draws):

(viewDidChangeGlyph points to changeGlyph & the other ones still point to myDrawCallback)
