  • Method Details

    • drawShape

      public Rectangle drawShape(Graphics g, Component component, boolean beforeOther)
      Description copied from class: ZoomShape
      Draw the shape using the given graphics handle on the given component.
      Specified by:
      drawShape in class ZoomShape
      Parameters:
      g - graphics
      component - component to draw on
      Returns:
      outer bounds of drawn region (should be same as getBounds());

    • drawShapeOutline

      public Rectangle drawShapeOutline(Graphics g, Component component)

    • drawShapeSolid

      public Rectangle drawShapeSolid(Graphics g, Component component)

    • getBounds

      public Rectangle getBounds(Component component)
      Specified by:
      getBounds in class ZoomShape
      Returns:
      the outer bounds of the zoom shape in pixels.

    • containsPoint

      public boolean containsPoint(Component component, Point pt)
      Description copied from class: ZoomShape
      Shape contains the point pt.

      Note that these are in screen pixel coordinates.

      Specified by:
      containsPoint in class ZoomShape
      Parameters:
      pt - point
      Returns:
      true if the point is within the shape.

    • newPoint

      public void newPoint(double x, double y)
      Description copied from class: ZoomShape
      New point to add to the shape - or update old point if it's a rectangle.
      Specified by:
      newPoint in class ZoomShape
      Parameters:
      x - x coordinate in display units such as time or bearing, NOT PIXELS
      y - y coordinate in display units such as time or bearing, NOT PIXELS

    • closeShape

      public void closeShape()
      Description copied from class: ZoomShape
      Shape is complete for whatever reason.
      Overrides:
      closeShape in class ZoomShape

    • removeOnZoom
