Class 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.

    • Field Summary

      Fields 
      Modifier and Type Field Description
      protected ChangeEvent changeEvent
      Only one ChangeEvent is needed per model instance since the event's only (read-only) state is the source property.
      protected EventListenerList listenerList
      The listeners waiting for model changes.

    • Constructor Summary

      Constructors 
      Constructor Description
      DefaultBoundedRangeModel()
      Initializes all of the properties with default values.
      DefaultBoundedRangeModel​(int value, int extent, int min, int max)
      Initializes value, extent, minimum and maximum.

    • Method Summary

      Modifier and Type Method Description
      void addChangeListener​(ChangeListener l)
      Adds a ChangeListener.
      protected void fireStateChanged()
      Runs each ChangeListener's stateChanged method.
      ChangeListener[] getChangeListeners()
      Returns an array of all the change listeners registered on this DefaultBoundedRangeModel.
      int getExtent()
      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 getMaximum()
      Returns the model's maximum.
      int getMinimum()
      Returns the model's minimum.
      int getValue()
      Returns the model's current value.
      boolean getValueIsAdjusting()
      Returns true if the value is in the process of changing as a result of actions being taken by the user.
      void removeChangeListener​(ChangeListener l)
      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 setValueIsAdjusting​(boolean b)
      Sets the valueIsAdjusting property.
      String toString()
      Returns a string that displays all of the BoundedRangeModel properties.
