I worked on this for a while and thought I had wx working but maybe I missed something or maybe there is a wx version issue. The real stumbling block was tk since it did not have a native idle and I was stuck trying to make it work with threading. In and of itself, this was OK, but it broke CTRL-C in ipython due to problems with cross thread signal handling. So I put the project on the back burner. Perhaps we can borrow some knowledge from the ipython developers who have recently made good progress here in various GUIs backends. > > 2) I want to limit the lifetime of my connection object, that takes care > of the communication with the microscope stage, so that the connection > is closed if I close the matplotlib figure.

Adding a close event at the mpl level should be fairly straight-forward, and shouldn't require much if any additional GUI programming since we already handle the window destroy event across backends for pylab figure management.
