[vtkusers] Re: timer example

[Dominik Szczerba]

According to the docu, the vtkHoverWidget is used to invoke an event when 
hovering in a render window. Do you propose to use a zero threshold to 
simulate an idle function? That sounds like an overkill for what I need. Iren 
allows for timers, is there really no way to regularly trigger arbitrary 
commands just like iren->AddObserver(vtkCommand::MouseMoveEvent, myCommand) 
does on a mouse movement?

Dominik
