Returns a string representation of this JCheckBox. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null. specific new aspects of the JFC components.

 public  void setBorderPaintedFlat(boolean b) 
{
        boolean oldValue = flat;
        flat = b;
        firePropertyChange(BORDER_PAINTED_FLAT_CHANGED_PROPERTY, oldValue, flat);

This method fires a property changed event. Some look and feels might not implement flat borders; they will ignore this property.

 public  void updateUI() 
{
        setUI((ButtonUI)UIManager.getUI(this));
}

Resets the UI property to a value from the current look and feel.
