I successfully made a program by using qvtkwidget, showing a few lines and points. And everything works perfectly. Next, I want to add an edit mode to my program, so that I can draw a line on it, or select some points or lines from it. Could anyone give me some guidelines for doing that? Do I need to use vtkRenderWindowInteractor? I tried to google but still can't find any clue.
