Those functions are still supported.  I can run the example on that page without issues using the development version of mpl, GTKAgg, and python 2.6.  There might be some other possibilities to consider.  For example, if you are working in the pylab mode and you have multiple figures and/or axes, the draw() command might be going to the wrong figure because draw() operates on whichever figure would be returned by gcf() (I believe).
