Hi, Paulo.I have a question. I Do not extend vtkInteractorStyleTrackballCamera,because I use C# program Kitware.VTK.When I drag the mouse (left click and drag) it rotates the object,but the event function: renWinInteractor.LeftButtonReleaseEvt+=LeftButtonReleaseEvt can not capture Button Release at once , As you say,in C++ program ,just need to forward the event to the superclass: vtkInteractorStyleTrackballCamera::OnLeftButtonDown(),I want to know how to realize this in Kitware.VTK using event function
regards
