[vtkusers] who 'observes' event?

[Amy Henderson]

Hi AJ,

The Enter event is not for detecting when the Enter key on the keyboard is 
pressed. The Enter event is invoked when the mouse pointer enters the 
render window. (There is also a Leave event.) To detect when Enter is 
pressed, you probably need to watch vtkCommand::KeyPressEvent and add code 
yourself for checking whether the key that was pressed is the Enter key.
