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.) | |
