wxPython/demo/ActiveXWrapper_Acrobat.py

   1 """
   2 <html><body>
   3 This demo shows how to embed an ActiveX control in a wxPython application, (Win32 only.)
   4 <p>
   5 The MakeActiveXClass function dynamically builds a new Class on the fly, that has the
   6 same signature and semantics as wxWindow.  This means that when you call the function
   7 you get back a new class that you can use just like wxWindow, (set the size and position,
   8 use in a sizer, etc.) except its contents will be the COM control.
   9 <p>
  10 This demo embeds the Adobe Acrobat Reader, and gives you some buttons for opening a PDF
  11 file, changing pages, etc. that show how to call methods on the COM object.  If you don't
  12 have Acrobat Reader 4.0 installed it won't work.
