"""
<html><body>
This demo shows how to embed an ActiveX control in a wxPython
application, (Win32 only.)
<p>
The MakeActiveXClass function dynamically builds a new Class on the
fly, that has the same signature and semantics as wxWindow. This
means that when you call the function you get back a new class that
you can use just like wxWindow, (set the size and position, use in a
sizer, etc.) except its contents will be the COM control.
<p>
This demo embeds the Internet Explorer WebBrowser control, and shows
how to receive events from the COM control. (The title bar and status
bar are updated as pages change, in addition to the log messages being
shown.)
