newbie: drawing lots of text?

I'm just getting started with wxPython on Mac OS 10.3. Can anyone point me toward sample code that will show me the nuts and bolts of writing large text files to the screen?

A wxScrolledWindow (two, rather, inside wxPanels inside a wxFrame, all with wxBoxSizers) looks like the right place, but I can't find anything in the demos or docs on the details of using it--the DC and so on. TextCtrl is very nice, but the 32Kb limit is way too low for my current project. I haven't done a lot of GUI programming (especially in recent years); the guts of my program are nifty enough, but the face is missing!
