Detailed Description

create a curve with a set of N points

The vtkSlicerClosedCurveWidget is used to create a closed curve widget with a set of N points. The widget handles all processing of widget events (that are triggered by VTK events). The vtkSlicerCurveRepresentation is responsible for all placement of the points, and curve manipulation. This is done through a main helper class: vtkPointPlacer. The representation is also responsible for drawing the points.

Event Bindings:

By default, the widget responds to the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events):

  LeftButtonPressEvent - triggers a Select event
  Alt + LeftButtonPressEvent - triggers a Rotate event
  MiddleButtonPressEvent - triggers a Translate event
  RightButtonPressEvent - triggers a Pick event
  Alt + RightButtonPressEvent - triggers a Scale event

MouseMoveEvent - triggers a Move event

  LeftButtonReleaseEvent - triggers an EndAction event
  MiddleButtonReleaseEvent - triggers an EndAction event
  RightButtonReleaseEvent - triggers an EndAction event

  LeftButtonDoubleClickEvent - triggers an Pick event
  MiddleButtonDoubleClickEvent - triggers an Pick event
  RightButtonDoubleClickEvent - triggers an Pick event

  Delete key event - triggers a Delete event
  Shift + Delete key event - triggers a Reset event
