[Goocanvas-devel] Infinite item bounds

[<dw...@gm...>]

Hi!

In my project I have several custom canvas items like rulers, cursors
and grids with infinite bounds, either horizontally or vertically (or
both). Until now, I used to set the bounds to very large numbers which
isn't easy in Python (which I'm using) because there is no
MAX_DOUBLE-like constant available. Strangely, using a value like 2**32
doesn't work and results in items getting chopped off. Anybody a
suggestion what to do about it?

As I think this is, or could become, a common use case, I wonder if it
would be sensible to introduce an API which allows the developer to set
any component of the item bounds (x1, x2, y1, y2) logically to
+/-infinity. What do you think?
