public class ColorStateButton

extends StateButton

implements java.awt.event.MouseListener

a button to select FIG draw/fill colors.

This button implements the xfig-style behaviour to select colors: left button opens a dialog window for direct color selection, middle and right button select the previous and next color. Note that the "state" variable of our parent class directly represents thei index of the selected color.
