Since wxPython already makes extensive use of event handlers, it is a
logical extension to allow events to be sent to GUI objects from
-alternate threads. A function called wxPostEvent allows you to do
+alternate threads. A function called wx.PostEvent allows you to do
this. It accepts an event and an event handler (window) and instead
of sending the event immediately in the current context like
ProcessEvent does, it processes it later from the context of the GUI
