<h2>wx.lib.iewin.IEHtmlWindow</h2>

The wx.lib.iewin.IEHtmlWindow class is one example of using ActiveX
controls from wxPython using the new wx.activex module.  This allows
you to use an ActiveX control as if it is a wx.Window, you can call
its methods, set/get properties, and receive events from the ActiveX
control in a very intuitive way.

<p> Using this class is simpler than ActiveXWrapper, doesn't rely on
the win32all extensions, and is more "wx\'ish", meaning that it uses
events and etc. as would be expected from any other wx window.
