wxPython/demo/ActiveXWrapper_IE.py

   1 """
   2 <html><body>
   3 This demo shows how to embed an ActiveX control in a wxPython
   4 application, (Win32 only.)
   5
   6 <p>
   7 The MakeActiveXClass function dynamically builds a new Class on the
   8 fly, that has the same signature and semantics as wxWindow.  This
   9 means that when you call the function you get back a new class that
  10 you can use just like wxWindow, (set the size and position, use in a
  11 sizer, etc.) except its contents will be the COM control.
  12
  13 <p>
  14 This demo embeds the Internet Explorer WebBrowser control, and shows
  15 how to receive events from the COM control.  (The title bar and status
  16 bar are updated as pages change, in addition to the log messages being
  17 shown.)
