Thanks for posting the example. This runs fine for me (I can pan, zoom, zoom to rect, the zoom to rect rubberband is drawn). Here is my version info; what do you have for same? jo...@udesktop191:tmp> uname -a SunOS udesktop191 5.10 Generic_139556-08 i86pc i386 i86pc j o...@udesktop191:tmp> python -c 'import gtk; print gtk.pygtk_version' (2, 6, 0) Also, if you know the persion of gtk you are running, that might help. Finally, you say you are running mpl 1.0, but your traceback says "/usr/lib/pymodules/python2.6/matplotlib/backends/backend_gtk.py", line 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 but line 606 in backend_gtk in mpl 1.0.0 is not what this traceback says. Are you sure you are picking up the right version? I suggest flushing all your matplotlib* files and dirs in site-packages and doing a clean install, and then running your test script with --verbose-debug so we can get a better look at what is happening.

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,

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

I use GTKAgg and it works. GTK doesn't.

I have added the example above with my changes. Zooming is the problem.
