| 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 Exploer 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.) |
