All Implemented Interfaces:

MouseListener, MouseMotionListener, EventListener

public class GradientSliderUI
extends MultiThumbSliderUI

The UI for the GradientSlider class. There are 3 properties you can use to customize the UI of a GradientSlider. You can set these for each slider by calling slider.putClientProperty(key,value);

Or you can set these globally by calling:
UIManager.put(key,value);

The three properties are:

Property Name	Default Value	Description
GradientSlider.useBevel	"false"	If this is true, then this slider will be painted in a rectangle with a bevel effect around the borders. If this is false, then this slider will be painted in a rounded rectangle.
GradientSlider.showTranslucency	"true"	If this is true, then the slider will reflect the opacity of the colors in the gradient, and paint a checkered background underneath the colors to indicate opacity. If this is false, then this slider will always paint with completely opaque colors, although the actual colors may be translucent.
GradientSlider.includeOpacity	"true"	This is used when the user double-clicks a color and a ColorPicker dialog is invoked. (So this value may not have any meaning if you override GradientSlider.doDoubleClick().) This controls whether the opacity/alpha controls are available in that dialog. This does not control whether translucent colors can be used in this slider: translucent colors are always allowed, if the user can enter them.
MultiThumbSlider.indicateComponent	"true"	If this is true, then the thumbs will only paint on this component when the mouse is inside this slider or when this slider as the keyboard focus.
MultiThumbSlider.indicateThumb	"true"	If this is true, then the thumb the mouse is over will gently fade into a slightly different color.
