public class javax.swing
DefaultBoundedRangeModel

Java SE 6
  
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 JavaBeansTM has been added to the java.beans package. Please see java.beans.XMLEncoder.

Fields
protected 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.

Constructors
public DefaultBoundedRangeModel()
Initializes all of the properties with default values. Those values are:
  • value = 0
  • extent = 0
  • minimum = 0
  • maximum = 100
  • adjusting = false
public DefaultBoundedRangeModel(int value, int extent, int min, int max)
Initializes value, extent, minimum and maximum. Adjusting is false. Throws an IllegalArgumentException if the following constraints aren't satisfied:
 min <= value <= value+extent <= max
 

Methods
public void addChangeListener(ChangeListener l)
Adds a ChangeListener. The change listeners are run each time any one of the Bounded Range model properties changes.
lthe ChangeListener to add
See also removeChangeListener, addChangeListener
protected void fireStateChanged()
Runs each ChangeListener's stateChanged method.
See also setRangeProperties, javax.swing.event.EventListenerList
public void removeChangeListener(ChangeListener l)
Removes a ChangeListener.
lthe ChangeListener to remove
See also addChangeListener, removeChangeListener
public String toString()
Returns a string that displays all of the BoundedRangeModel properties.

Properties
public ChangeListener[] getChangeListeners()
Returns an array of all the change listeners registered on this DefaultBoundedRangeModel.
returnall of this model's ChangeListeners or an empty array if no change listeners are currently registered
since1.4
See also addChangeListener, removeChangeListener
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
 
See also setExtent
public int getExtent()
Returns the model's extent.
returnthe model's extent
See also setExtent, getExtent
public EventListener[]<T> getListeners(Class 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.
listenerTypethe type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener
returnan array of all objects registered as FooListeners on this model, or an empty array if no such listeners have been added
ThrowsClassCastException: if listenerType doesn't specify a class or interface that implements java.util.EventListener

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
 
See also setMaximum
public int getMaximum()
Returns the model's maximum.
returnthe model's maximum
See also setMaximum, getMaximum
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
 
See also getMinimum, setMinimum
public int getMinimum()
Returns the model's minimum.
returnthe model's minimum
See also setMinimum, getMinimum
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
 
See also setValue
public int getValue()
Returns the model's current value.
returnthe model's current value
See also setValue, getValue
public void setValueIsAdjusting(boolean b)
Sets the valueIsAdjusting property.
See also getValueIsAdjusting, setValue, setValueIsAdjusting
public boolean getValueIsAdjusting()
Returns true if the value is in the process of changing as a result of actions being taken by the user.
returnthe value of the valueIsAdjusting property
