public class JSlider
extends JComponent
implements SwingConstants, Accessible

A component that lets the user graphically select a value by sliding a knob within a bounded interval. The knob is always positioned at the points that match integer values within the specified interval.

The slider can show both major tick marks, and minor tick marks between the major ones. The number of values between the tick marks is controlled with setMajorTickSpacing and setMinorTickSpacing. Painting of tick marks is controlled by setPaintTicks.

Sliders can also print text labels at regular intervals (or at arbitrary locations) along the slider track. Painting of labels is controlled by setLabelTable and setPaintLabels.

For further information and examples see How to Use Sliders, a section in The Java Tutorial.

Warning: Swing is not thread safe. For more information see Swing's Threading Policy.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

Field Summary

Fields

Modifier and Type	Field	Description
protected ChangeEvent	changeEvent	Only one ChangeEvent is needed per slider instance since the event's only (read-only) state is the source property.
protected ChangeListener	changeListener	The changeListener (no suffix) is the listener we add to the slider's model.
protected int	majorTickSpacing	The number of values between the major tick marks -- the larger marks that break up the minor tick marks.
protected int	minorTickSpacing	The number of values between the minor tick marks -- the smaller marks that occur between the major tick marks.
protected int	orientation	Whether the slider is horizontal or vertical The default is horizontal.
protected BoundedRangeModel	sliderModel	The data model that handles the numeric maximum value, minimum value, and current-position value for the slider.
protected boolean	snapToTicks	If true, the knob (and the data value it represents) resolve to the closest tick mark next to where the user positioned the knob.
