| | 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.) |
