3This demo shows how to embed an ActiveX control in a wxPython
4application, (Win32 only.)
5
6<p>
7The MakeActiveXClass function dynamically builds a new Class on the
8fly, that has the same signature and semantics as wxWindow. This
9means that when you call the function you get back a new class that
10you can use just like wxWindow, (set the size and position, use in a
11sizer, etc.) except its contents will be the COM control.
12
13<p>
14This demo embeds the Internet Explorer WebBrowser control, and shows
15how to receive events from the COM control. (The title bar and status
16bar are updated as pages change, in addition to the log messages being
17shown.)
