public class LightTable extends JLayeredPane
A LightTable is a container that places an invisible drawing table on top of another component and allows that component to become a drawing surface. When activated, the LightTable listens for mouse events on the surface and draws rubber-band lines according to one of various drawing modes. It then reports the results of the drawing operation via a change event.

      Parameters:
      component - the component to use as a base layer.

    • removeChangeListener

      public void removeChangeListener(ChangeListener listener)
      Removes the specified change listener from the listeners list.

    • addChangeListener

      public void addChangeListener(ChangeListener listener)
      Adds a change listener to the listeners list. A change event is fired when the light table detects the finished drawing. The finished shape may be retrieved using getShape.

    • getActive

      public boolean getActive()
      Gets the light table activity mode.

    • setActive

      public void setActive(boolean flag)
      Sets the light table active or inactive.

      Sets the drawing mode to the specified mode.

    • getShape

      public Shape getShape()
      Gets the current user shape. The shape differs depending on the drawing mode as follows:
      • Mode.POINT = Line2D

      • Mode.GENERAL_PATH = Line2D
      • Mode.IMAGE = Line2D
      • Mode.IMAGE_TRANSLATE = Line2D
      • Mode.IMAGE_ROTATE = Line2D
      Returns:
      the current user shape or null if not available.

    • main

      public static void main(String[] argv)
      Tests this class.
      Parameters:
      argv - the array of command line parameters.
