@JavaBean(defaultProperty="UI", description="A component that supports selecting a integer value from a range.") public class JSlider extends JComponent implements SwingConstants, Accessible
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

imageUpdate
method of an ImageObserver
is called when more information about an image which had been previously requested using an asynchronous routine such as the drawImage
method of Graphics
becomes available. See the definition of imageUpdate
for more information on this method and its arguments. The imageUpdate
method of Component
incrementally draws an image on the component as more of the bits of the image are available.
If the system property awt.image.incrementaldraw
is missing or has the value true
, the image is incrementally drawn. If the system property has any other value, then the image is not drawn until it has been completely loaded.
Also, if incremental drawing is in effect, the value of the system property awt.image.redrawrate
is interpreted as an integer to give the maximum redraw rate, in milliseconds. If the system property is missing or cannot be interpreted as an integer, the redraw rate is once every 100ms.
The interpretation of the x
, y
, width
, and height
arguments depends on the value of the infoflags
argument.

and the slider minimum is zero, then labels will be created for the values 0, 10, 20, 30, and so on. For the labels to be drawn on the slider, the returned Hashtable
