Does this example work for you?
http://matplotlib.sourceforge.net/examples/user_interfaces/embedding_in_gtk3.html
Yes it works and a bit cleanup of my imports helped in my program too.
However if I add NavigateToolbar to the example above I get problems.
mtoolbar = NavigationToolbar(canvas, win)
then I get error when I try to zoom in a graph:
/usr/lib/pymodules/python2.6/matplotlib/backends/backend_gtk.py:621:
DeprecationWarning: Use the new widget gtk.Tooltip self.tooltips =
gtk.Tooltips() /usr/lib/pymodules/python2.6/matplotlib/backends/backend_gtk.py:601:
GtkWarning: gdk_drawable_copy_to_image: assertion `src_y >= 0' failed
self._imageBack = axrect, drawable.get_image(*axrect) Traceback (most
recent call last): File

606, in idle_draw drawable.draw_image(gc, imageBack, 0, 0, *lastrect)
TypeError: Gdk.Drawable.draw_image() argument 2 must be gtk.gdk.Image,
not None
The graph zooms, but I don't see the rubberband. I got same
error in 1.0:
TypeError: Gdk.Drawable.draw_image() argument 2 must be gtk.gdk.Image,
not None
It uses a ScrolledWindow.
Also, are you using backend_gtk or backend_gtkagg (and does it matter
for your problem?)
I use GTKAgg and it works. GTK doesn't.
If you could create a minimal example starting with
embedding_in_gtk3.py that replicates your problem, we're more likely
to be able to help.
I have added the example above with my changes. Zooming is the problem.
