/**
|
|
* <p>
|
|
* The JSlider is a Swing component that allows selection of a value within a
|
|
* range by adjusting a thumb in a track. The values for the minimum,
|
|
* maximum, extent and value are stored in a {@link
|
|
* DefaultBoundedRangeModel}.
|
|
* </p>
|
|
*
|
|
* <p>
|
|
* JSliders have the following properties:
|
|
* </p>
|
|
*
|
|
* <table>
|
|
* <tr><th> Property </th><th> Stored in </th><th> Bound? </th></tr>
|
|
* <tr><td> extent </td><td> model </td><td> no </td></tr>
|
|
* <tr><td> inverted </td><td> slider </td><td> yes </td></tr>
|
|
* <tr><td> labelTable </td><td> slider </td><td> yes </td></tr>
|
|
* <tr><td> majorTickSpacing </td><td> slider </td><td> yes </td></tr>
|
|
* <tr><td> maximum </td><td> model </td><td> no </td></tr>
|
|
* <tr><td> minimum </td><td> model </td><td> no </td></tr>
|
|
* <tr><td> minorTickSpacing </td><td> slider </td><td> yes </td></tr>
|
|
* <tr><td> model </td><td> slider </td><td> yes </td></tr>
|
|
* <tr><td> orientation </td><td> slider </td><td> yes </td></tr>
|
|
* <tr><td> paintLabels </td><td> slider </td><td> yes </td></tr>
|
|
* <tr><td> paintTicks </td><td> slider </td><td> yes </td></tr>
|
|
* <tr><td> snapToTicks </td><td> slider </td><td> no </td></tr>
|
|
* <tr><td> value </td><td> model </td><td> no </td></tr>
|
|
* <tr><td> valueIsAdjusting </td><td> model </td><td> no </td></tr>
|
|
* </table>
|
|
*
|
|
* <p>
|
|
* The various behavioral aspects of these properties follows:
|
|
* </p>
|
|
*
|
|
* <ul>
|
|
* <li>
|
|
* When non-bound properties stored in the slider change, the slider fires
|
|
* ChangeEvents to its ChangeListeners.
|
|
* </li>
|
|
* <li>
|
|
* When bound properties stored in the slider change, the slider fires
|
|
* PropertyChangeEvents to its PropertyChangeListeners
|
|
* </li>
|
|
* <li>
|
|
* If any of the model's properties change, it fires a ChangeEvent to its
|
|
* ChangeListeners, which include the slider.
|
|
* </li>
|
|
* <li>
|
|
* If the slider receives a ChangeEvent from its model, it will propagate the
|
|
* ChangeEvent to its ChangeListeners, with the ChangeEvent's "source"
|
|
* property set to refer to the slider, rather than the model.
|
|
* </li>
|
|
* </ul>
