public class: DefaultBoundedRangeModel [javadoc | source]
java.lang.Object
   javax.swing.DefaultBoundedRangeModel

All Implemented Interfaces:
    BoundedRangeModel, java$io$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 JavaBeansTM has been added to the java.beans package. Please see java.beans.XMLEncoder .

Field Summary
protected transient  ChangeEvent changeEvent    Only one ChangeEvent is needed per model instance since the event's only (read-only) state is the source property. The source of events generated here is always "this". 
protected  EventListenerList listenerList    The listeners waiting for model changes. 
Constructor:
 public DefaultBoundedRangeModel() 
 public DefaultBoundedRangeModel(int value,
    int extent,
    int min,
    int max) 
Method from javax.swing.DefaultBoundedRangeModel Summary:
addChangeListener,   fireStateChanged,   getChangeListeners,   getExtent,   getListeners,   getMaximum,   getMinimum,   getValue,   getValueIsAdjusting,   removeChangeListener,   setExtent,   setMaximum,   setMinimum,   setRangeProperties,   setValue,   setValueIsAdjusting,   toString

Method from javax.swing.DefaultBoundedRangeModel Detail:
 public  void addChangeListener(ChangeListener l) 
    Adds a ChangeListener. The change listeners are run each time any one of the Bounded Range model properties changes.
 protected  void fireStateChanged() 
    Runs each ChangeListener's stateChanged method.
 public ChangeListener[] getChangeListeners() 
    Returns an array of all the change listeners registered on this DefaultBoundedRangeModel.
 public int getExtent() 
    Returns the model's extent.
 public T[] getListeners(Class<T> listenerType) 
    Returns an array of all the objects currently registered as FooListeners upon this model. FooListeners are registered using the addFooListener method.

    You can specify the listenerType argument with a class literal, such as FooListener.class. For example, you can query a DefaultBoundedRangeModel instance m for its change listeners with the following code:

    ChangeListener[] cls = (ChangeListener[])(m.getListeners(ChangeListener.class));
    If no such listeners exist, this method returns an empty array.
 public int getMaximum() 
    Returns the model's maximum.
 public int getMinimum() 
    Returns the model's minimum.
 public int getValue() 
    Returns the model's current value.
 public boolean getValueIsAdjusting() 
    Returns true if the value is in the process of changing as a result of actions being taken by the user.
 public  void removeChangeListener(ChangeListener l) 
    Removes a ChangeListener.
 public  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:
        minimum <= value <= value+extent <= maximum
    
 public  void setMaximum(int n) 
    Sets the maximum to n after ensuring that n that the other three properties obey the model's constraints:
        minimum <= value <= value+extent <= maximum
    
 public  void setMinimum(int n) 
    Sets the minimum to n after ensuring that n that the other three properties obey the model's constraints:
        minimum <= value <= value+extent <= maximum
    
 public  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:
        minimum <= value <= value+extent <= maximum
    

    At most, one ChangeEvent is generated.

 public  void setValue(int n) 
    Sets the current value of the model. For a slider, that determines where the knob appears. Ensures that the new value, n falls within the model's constraints:
        minimum <= value <= value+extent <= maximum
    
 public  void setValueIsAdjusting(boolean b) 
    Sets the valueIsAdjusting property.
 public String toString() 
    Returns a string that displays all of the BoundedRangeModel properties.
