Learning wxPython by Example.

The following code shows an example of a wxPython application with a frame containing a menu bar, status bar and panel. The panel contains a label and a button that is bound to an exit function. The menu bar has a Help->About action that is bound to a dialog box. The dialog box shows how to display an HTML message and bring up a link in the user's default browser. You might find this example useful as a starting point that you can adapt. In a larger program it would be best to put the about box code into a separate file so that the main program file does not become too large.
