      Description copied from interface: ILcdIcon
      Draw the ILcdIcon at the specified location. ILcdIcon implementations may use the Component argument to get properties useful for painting, e.g. the foreground or background color.
      Specified by:
      paintIcon in interface ILcdIcon
      Parameters:
      c - a Component to retrieve properties from.
      g - the Graphics on which the icon will be painted.
      x - the x position where the icon will be painted. x is the first coordinate of the top left corner point of the icon.
      y - the y position where the icon will be painted. y is the second coordinate of the top left corner point of the icon.

      getIconWidth in interface ILcdIcon
      Returns:
      the fixed width of the icon.

    • setIconWidth

      public void setIconWidth(int aIconWidth)
      Description copied from interface: ILcdResizeableIcon
      Set the width of the icon.
      Specified by:
      setIconWidth in interface ILcdResizeableIcon
      Parameters:
      aIconWidth - the new width.

    • getIconHeight

      public int getIconHeight()
      Description copied from interface: ILcdIcon

    • equals

      public boolean equals(Object obj)
      Overrides:
      equals in class Object

    • clone

      public Object clone()
      Description copied from interface: ILcdCloneable

      Makes Object.clone() public.

      When for example extending from java.lang.Object, it can be implemented like this: 
      
 public Object clone() {
   try {
     return super.clone();
   } catch ( CloneNotSupportedException e ) {
     // Cannot happen: extends from Object and implements Cloneable (see also Object.clone)
     throw new RuntimeException( e );
   }
 }
      Specified by:
      clone in interface ILcdCloneable
      Overrides:
      clone in class Object

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • anchorPointSFCT

      public void anchorPointSFCT(Point aPointSFCT)
      Updates the given point to the location of the icon's anchor point, in relative coordinates with respect to the top left. The x-coordinate of the anchor point typically lies between 0 and getWidth(). The y-coordinate typically lies between 0 and getHeight().

      This implementation reuses the anchor point of the delegate icon. If the delegate icon is resized, the anchor point is shifted accordingly. If the delegate icon is not anchored, the icon center is returned.

      Specified by:
      anchorPointSFCT in interface ILcdAnchoredIcon
      Parameters:
      aPointSFCT - the point that has to be moved to the location of the anchor point
