| 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. | |
