Re: [wxVTK] wxVTK + GTK + EVT_CHAR

[Sander N. <nie...@st...>]

I find it strange that this is needed.

In the CVS version for wxVTKRenderWindowInteractor there are  
registrations for EVT_KEY_DOWN, EVT_KEY_UP, and EVT_CHAR. We should  
thus be receiving both EVT_KEY_DOWN and EVT_CHAR events from  
wxWidgets. This should result in invoke events for both  
vtkCommand::KeyPressEvent and vtkCommand::CharEvent.

We even call the event.Skip() in the OnKeyDown handler in order to  
make sure we also get the EVT_CHAR event (as explained in http://docs.wxwidgets.org/stable/wx_wxkeyevent.html#wxkeyevent) 
.

If the wxVTKRenderWindowInteractor object is not receiving EVT_CHAR  
events (after a EVT_KEY_DOWN event) then this sounds more like a  
wxWidgets issue.
