wxWidgets quick start

This is the wxWidgets spin control example included in AVC distribution. It comes into two versions. The first has the GUI generated from a wxGlade UI description. The second has the GUI generated directly by program instructions. For full details see the "wxWidgwts examples" chapter of the user manual.

Source code: wxGlade version (file wx_spinctrl.py, needs also wx_spinctrl.xrc)
