paint

public void paint(JaxoGraphics2D g2,
                  int x,
                  int y)

Paints an unmarked handle at (x, y).

Parameters:

g2 - The graphics context to paint to.

x - The x position of the handle.

y - The y position of the handle.

paint

public void paint(JaxoGraphics2D g2,
                  int x,
                  int y,
                  boolean marked)

Paints a handle at (x, y).

Parameters:

g2 - The graphics context to paint to.

x - The x position of the handle.

y - The y position of the handle.

marked - True if the handle should be marked (selected).

paint

public void paint(JaxoGraphics2D g2,
                  int x,
                  int y,
                  boolean marked,
                  boolean secondary)

Paint the handle at a given position.

Specified by:

paint in interface JaxoHandle

Parameters:

g2 - The graphics context to paint to.

x - The x position of the handle.

y - The y position of the handle.

marked - True if the handle should be painted as marked. A marked handle is one that has been selected, eg for an edit operation.

secondary - True if this is a secondary handle. A secondary handle is one that cannot be selected in the current context.

paintSecondary

public void paintSecondary(JaxoGraphics2D g2,
                           int x,

Parameters:

g2 - The graphics context to paint to.

x - The x position of the handle.

y - The y position of the handle.

paintSecondary

public void paintSecondary(JaxoGraphics2D g2,

                           boolean marked)

Paints a handle in secondary color at (x, y).

Parameters:

g2 - The graphics context to paint to.

x - The x position of the handle.

y - The y position of the handle.

marked - True if the handle should be marked (selected).

paint

public abstract void paint(JaxoGraphics2D g2,
                           int x,
