Class DefaultBoundedRangeModel

java.lang.Object
javax.swing.DefaultBoundedRangeModel
All Implemented Interfaces:
Serializable, BoundedRangeModel

public class DefaultBoundedRangeModel extends Object implements BoundedRangeModel, Serializable
A generic implementation of BoundedRangeModel.

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.

    Method
    Description
    void

    Runs each ChangeListener's stateChanged method.
    Returns an array of all the change listeners registered on this DefaultBoundedRangeModel.
    int
    Returns the model's extent.
    <T extends EventListener>
    T[]
    getListeners(Class<T> listenerType)
    Returns an array of all the objects currently registered as FooListeners upon this model.
    int
    Returns the model's maximum.
    int
    Returns the model's minimum.
    int
    Returns the model's current value.
    boolean
    Returns true if the value is in the process of changing as a result of actions being taken by the user.
    void
    Removes a ChangeListener.
    void
    setExtent(int n)
    Sets the extent to n after ensuring that n is greater than or equal to zero and falls within the model's constraints:
    void
    setMaximum(int n)
    Sets the maximum to n after ensuring that n that the other three properties obey the model's constraints:
    void
    setMinimum(int n)
    Sets the minimum to n after ensuring that n that the other three properties obey the model's constraints:
    void
    setRangeProperties(int newValue, int newExtent, int newMin, int newMax, boolean adjusting)
    Sets all of the BoundedRangeModel properties after forcing the arguments to obey the usual constraints:
    void
    setValue(int n)
    Sets the current value of the model.
    void
    Sets the valueIsAdjusting property.
    Returns a string that displays all of the BoundedRangeModel properties.
