Interface RangeModel

All Known Implementing Classes:
DefaultRangeModel

public interface RangeModel

This interface represents a range of possible values as well as the current values. There is a minumum and maximum value, a current value, and the extent. One use for a RangeModel is a scrollbar. There is a minimum value (the top of the scrollbar), a maximum value (the bottom of the scrollbar), a current value (the top of the thumb), and an extent (the length of the thumb).


Field Summary
static java.lang.String PROPERTY_EXTENT
          Extent property name
static java.lang.String PROPERTY_MAXIMUM
          Maximum property name
static java.lang.String PROPERTY_MINIMUM
          Minimum property name
static java.lang.String PROPERTY_VALUE
          Value property name
 
Method Summary
 void addPropertyChangeListener (java.beans.PropertyChangeListener listener)
          Registers listener as a PropertyChangeListener of this RangeModel.
 int getExtent ()
          Returns the extent.
 int getMaximum ()
          Returns the maximum value in the range.
 int getMinimum ()
          Returns the minimum value in the range.
 int getValue ()
          Returns the current value.
 boolean isEnabled ()
          Returns true if this RangeModel is enabled.
 void removePropertyChangeListener (java.beans.PropertyChangeListener listener)
          Removes the given listener from this RangeModel's list of PropertyChangeListeners.
 void setAll (int min, int extent, int max)
          Sets min, extent, and max all at once.
 void setExtent (int extent)
          Sets the extent.
 void setMaximum (int max)
          Sets the maximum value of the range.
 void setMinimum (int min)
          Sets the minimum value of the range.
 void setValue (int value)
          Sets the current value.
