paintIcon

public void paintIcon(java.awt.Component c,
                      java.awt.Graphics g,
                      int x,
                      int y)

Draws the icon at the specified location. Calls paintRealizer(y.view.EdgeRealizer, java.awt.Graphics2D).

Specified by:

paintIcon in interface javax.swing.Icon

Parameters:

c - ignored

g - the graphics context to draw upon.

x - x-coordinate of the icon's location.

y - y-coordinate of the icon's location.

paintRealizer

protected void paintRealizer(EdgeRealizer er,
                             java.awt.Graphics2D gfx)

Paints the given edge realizer. The actual painting is delegated to the realizer, so changing the visible attributes of the realizer will influence the drawing on subsequent runs of this method without the need to reinitialize this icon.

Called from paintIcon(java.awt.Component, java.awt.Graphics, int, int). The calling method will dispose the graphics context afterwards.
