[python-win32] wxPython/Pythonwin interplay/Richtext Controls

[Hannes Grund]

Thanks for reply,

Sorry for posting incomplete information, 
the options passed to wxTextCtrl determine the the version of the used
RichEdit.dll and (according to the sources) the window class string.
(I don't know anything about the mechanism how pythonwin recognizes which of
its classes to instanciate, maybe this is my problem).
The use of wxTE_RICH option causes the window class string to be "RICHEDIT",
when using the option wxTE_RICH2 the window class string will be
"RichEdit20".

I considered to do it via SendMessage, but on one hand some 
options cannot be set after the creation of the control (and I have to 
create within wx), I tried to construct the EditStreamCallback functions
manually by using struct and array but I simply failed 
(anybody out there with an pointer to an working example ??)

Thanks in advance,

  Hannes Grund
