[vtkusers] Find out which qVtkWidget the mouse is over

[tao sun]

Hi,

I overload mouseEvents as functions of the vtkInteractorStyleImage
subclass. Do you mean I should name a member to indicate the current
interactor and QVtkWidget? How could a slot function of the mouseevent know
that which QvtkWidget's interactor call it?


Thanks,
Sun Tao
