Hi JY Bian, What exactly did you do? Did you create your own widget or did you use the recommended QmitkStdMultiWidget? In order to interact with the mouse a DisplayActionEventHandler has to be used. It should be connected to a DisplayActionEventBroadcast, which will receive and forward mouse interactions. You can see how the DisplayActionEventBroadcast is initialized for the QmitkStdMultiWidget inside its abstract base class: QmitkAbstractMultiWidget::Impl:: InitializeDisplayActionEventHandling
Inside QmitkStdMultiWidget::InitializeMultiWidget you can see how the DisplayActionEventHandlerStd is used as a DisplayActionEventHandler for the Std-case. You need to do this if you have a custom multi widget that does not inherit QmitkAbstractMultiWidget.

But I cannot interact with the image I display in the window as the software MITKWorkbench does, such as rotating my view in 3D window with pressing and moving my mouse, or move crossline after mouseclick somewhere at 2D window. I wonder how I can start mouse interaction with QmitkStdMultiWidgets. Btw, I didnt see that part on the tutorial, "Part II Setup standard interaction with the mouse" has nothing in it. Plz tell me if I have missed something, thank you so much.
