wxruby users - Oct 2004 - Loading wxListCtrl subclass from XRC file

I''m trying to use the wxLC_VIRTUAL style of the wxListCtrl, which seems
to require that I subclass the control (as opposed to being able to 
provide a data model a la Swing or Cocoa), and I''m running into trouble
when loading the control from an XRC file.  Apparently I need to 
specify the name of my subclass in the XRC as follows:

     <object class="wxListCtrl"
subclass="MyVeryOwnListCtrl"
name="custom_list">
       ...
     </object>

When I do this, however, I get a message from WxWidgets saying that 
"Subclass ''MyVeryOwnListCtrl'' not found for resource
''custom_list'', not
subclassing!".  I gather from the WxWidgets documentation that the XML 
resource loader needs to know about the existence of my subclass 
somehow, but so far I haven''t been able to figure out how to do that.

Any ideas?

Thanks much,
Marshall

wxruby doesn''t support XRC subclassing. I wish I could say it was on
the
radar, but it''s really a difficult thing to implement (XRC subclassing 
only works with C++ classes that use the wxClassInfo dynamic 
construction, which we don''t). Best I can suggest is put a panel where 
you want the list control to be, and then add the list control into the 
Panel after loading the dialog.
