[pygtk] Cairo drawing problems

[Adam Schreiber]

I have found a couple of unusual behaviors of drawing with cairo in
Pygtk and was wondering if there were solutions or if they needed to
be reported as bugs.

The first is that a sub-class of a GtkDrawingArea widget renders
correctly on its own in a window, but if placed in a box with another
widget, only renders if it's the first of only two widgets in the
container.  It does not render at all  hen placed in a GtkTable.  This
behavior is demonstrated in test.py.

The second is that when sub-classing GtkDrawingArea,
self.get_allocation returns a GdkRectangle with the right x, height
and width values but the wrong y value.  This behavior is demonstrated
in deka.py.  There are 5 rows of polygons in each column.  If you
can't see them, make your window taller until the fifth row comes into
view.  This is the problem.

Cheers,
