Advanced Events in wxPython

Abstract

• Since most GUI-applications are meant to merely "react" to user's action, event-programming is a good strategy to write GUI-applications. In this article, we shall describe the way events are processed in wxPython 2.6, and present the complete hierarchy of events used in wxPython.

Introduction

• Event Handling is a complex enough matter in wxPython to be treated as a separate subject. We shall, here, try to present it as exhaustively as possible. Someday?

Hierarchy of Events

• In wxPython, Events' base classes are wxEvent. Try the following code to assure yourself of it:

  >>> import wx
  >>> issubclass(wxCloseEvent,wxEvent)
  True

  And:

  >>> issubclass(wxCloseEvent,wxEventPtr)
  False

Event processing

• Use Bind() to bind wxObjects to wxEvents. Generally, self.Bind(wx.SOME_EVENT, callbackFn, self.boundObject). I dunno, that's a pretty crap example but hey it's something... As I dig around in this more I'll post more, but I'm just a n00b. --TomPlunket
