Class com.sun.java.swing.DefaultBoundedRangeModel

java.lang.Object
   |
   +----com.sun.java.swing.DefaultBoundedRangeModel

public class DefaultBoundedRangeModel

extends Object

implements BoundedRangeModel, Serializable

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 Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.

BoundedRangeModel

changeEvent

Only one ChangeEvent is needed per model instance since the event's only (read-only) state is the source property.

listenerList

DefaultBoundedRangeModel()

Initializes all of the properties as follows:

• value = 0
• extent = 0
• minimum = 0
• maximum = 100
• adjusting = false

DefaultBoundedRangeModel(int, int, int, int)

Initializes value, extent, minimum and maximum.

addChangeListener(ChangeListener)

Adds a ChangeListener.

fireStateChanged()

Run each ChangeListeners stateChanged() method.

getExtent()

getMaximum()

getMinimum()

getValue()

getValueIsAdjusting()

Returns true if the value is in the process of changing as a result of actions being taken by the user.

removeChangeListener(ChangeListener)

Removes a ChangeListener.

setExtent(int)

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
 

setMaximum(int)

Sets the maximum to n after ensuring that n that the other three properties obey the model's constraints:

 minimum <= value <= value+extent <= maximum
 

setMinimum(int)

Sets the minimum to n after ensuring that n that the other three properties obey the model's constraints:

 minimum <= value <= value+extent <= maximum
 

setRangeProperties(int, int, int, int, boolean)

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.

setValue(int)

Sets the value to n after ensuring that n falls within the model's constraints:

 minimum <= value <= value+extent <= maximum
 

setValueIsAdjusting(boolean)

Sets the valueIsAdjusting property.

toString()

Returns a string that displays all of the BoundedRangeModel properties.

 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".

Returns:

the value of the valueIsAdjusting property
