[vtkusers] RightbuttonReleaseEvent

[舞法舞天]

Hi
     I use the observer to get the right mouse button click on a widget,but it dosen't work， can anyone tell me the right way to do this?
    my code as follow
   vtkCaptionWidget* captionWidget =
	vtkCaptionWidget::New();
vtkCaptionCallback* captionCall = vtkCaptionCallback::New();
captionWidget->SetInteractor(this->GetInteractor());
	captionWidget->SetRepresentation(captionRepresentation);
     
	captionWidget->AddObserver(vtkCommand::RightButtonReleaseEvent, captionCall);
	captionWidget->On();
}
