Summary

0000553: Render dont send EndEvent if no props

Description

vtkRender dont send any EndEvent if it happens
to render with a PropArrayCount == 0
This is a problem if using the StartEvent/EndEvent
callbacks to change e.g. state of cursor.
The solution could be to add
    this->InvokeEvent(vtkCommand::EndEvent,NULL);
in vtkRenderer.cxx (diff -u below):

   if ( this->PropArrayCount == 0 )
     {
+ this->InvokeEvent(vtkCommand::EndEvent,NULL);
     return 0;
     }

(0000587) Mathieu Malaterre (developer) 2004-01-30 14:34	This was fixed long time ago: http://vtk.org/cgi-bin/cvsweb.cgi/VTK/Rendering/vtkRenderer.cxx.diff?r1=1.194&r2=1.195 [^] Do we need to merge this to VTK 4.2 ?
