This demo shows how to embed an ActiveX control in a wxPython
|
|
|
|
|
application, (Win32 only.)
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
The MakeActiveXClass function dynamically builds a new Class on the
|
|
|
|
|
fly, that has the same signature and semantics as wxWindow. This
|
|
|
|
|
means that when you call the function you get back a new class that
|
|
|
|
|
you can use just like wxWindow, (set the size and position, use in a
|
|
|
|
|
sizer, etc.) except its contents will be the COM control.
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
This demo embeds the Internet Exploer WebBrowser control, and shows
|
|
|
|
|
how to receive events from the COM control. (The title bar and status
|
|
|
|
|
bar are updated as pages change, in addition to the log messages being
|
|
|
|
|
shown.)
