It looks like exactly what I had in mind with respect to set_ticks. I 
wasn't thinking about set_ticklabels; my sense is that manually setting 
ticklabels tends to be tricky and error-prone, and should be 
discouraged. Maybe it should be permitted only when a FixedLocator is 
already in use.

Attached patch against svn (without your patch) shows how this can be 
done for the Axes methods. I would be more difficult (but not 
impossible) for the Axis methods, because we need to use them. I think 
that handling the Axes methods *may* be worthwhile (marginal), but 
handling the Axis methods is more trouble than it is worth.

Hi Nicolas,
thank you for providing glumpy. I started using it for my own project.
The previous, pyglet based version of glumpy worked flawlessly on my
system (WinXP). I want to report about problems with the latest
version.
1.) On Windows glumpy fails on importing the Python termios module,
since it is for Unix platforms only.
2.) Resolving this, the demos start, but are mostly not usable, since
mouse scroll events and passive mouse motions events are not created.
This might be a problem of the glut implementation on Windows (I am
using PyOpenGL 3.0.1b2). Who knows?
3.) On OpenSuse11.1 the demos fail at 'glCreateProgram'. The demos
used to work with the previous version. I use the Intel Q45 graphics
chipset.
In the future I might spend some time on this problems and I would
like to contribute to glumpy, even if it's only testing on platforms
available to me.

A patch is attached.
It does some refactoring and introduces three new methods, set_ticks,
set_ticklabels and update_ticks, on the colorbar class.
So, now one can do
 imshow(np.arange(100).reshape((10,10)))
 cb = colorbar()
 cb.set_ticks([0, 40, 80])
Issuing a warning when user try to call Axis.set_ticks (or others)
directly seems not straight forward as the axes can be created
externally (i.e., when *cax* is provided).
I'll wait for response for a few more days and will commit the change.
