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.

Since:
1.2

    • changeEvent

      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".

    • listenerList

      protected EventListenerList listenerList
      The listeners waiting for model changes.

  • Constructor Details

    • DefaultBoundedRangeModel

      public DefaultBoundedRangeModel()
      Initializes all of the properties with default values. Those values are:
      • value = 0
      • extent = 0
      • minimum = 0
      • maximum = 100
      • adjusting = false

    • DefaultBoundedRangeModel

      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
      Parameters:
      value - an int giving the current value
      extent - the length of the inner range that begins at the model's value
      min - an int giving the minimum value
      max - an int giving the maximum value
