public class BasicSplitPaneDivider

extends Container

implements PropertyChangeListener

Divider used by BasicSplitPaneUI. Subclassers may wish to override paint to do something more interesting. The border effect is drawn in BasicSplitPaneUI, so if you don't like that border, reset it there. To conditionally drag from certain areas subclass mousePressed and call super when you wish the dragging to begin.

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^TM has been added to the java.beans package. Please see XMLEncoder.

Constructor Summary
BasicSplitPaneDivider(BasicSplitPaneUI ui)     Creates an instance of BasicSplitPaneDivider.

 

Method Summary
protected  JButton	createLeftOneTouchButton()     Creates and return an instance of JButton that can be used to collapse the left component in the split pane.
protected  JButton	createRightOneTouchButton()     Creates and return an instance of JButton that can be used to collapse the right component in the split pane.
protected  void	dragDividerTo(int location)     Messages the BasicSplitPaneUI with dragDividerTo that this instance is contained in.
protected  void	finishDraggingTo(int location)     Messages the BasicSplitPaneUI with finishDraggingTo that this instance is contained in.
BasicSplitPaneUI	getBasicSplitPaneUI()     Returns the SplitPaneUI the receiver is currently in.
Border	getBorder()     Returns the border of this component or null if no border is currently set.
int	getDividerSize()     Returns the size of the divider, that is the width if the splitpane is HORIZONTAL_SPLIT, or the height of VERTICAL_SPLIT.
Insets	getInsets()     If a border has been set on this component, returns the border's insets, else calls super.getInsets.
Dimension	getMinimumSize()     Returns dividerSize x dividerSize
Dimension	getPreferredSize()     Returns dividerSize x dividerSize
protected  void	oneTouchExpandableChanged()     Messaged when the oneTouchExpandable value of the JSplitPane the receiver is contained in changes.
void	paint(Graphics g)     Paints the divider.
protected  void	prepareForDragging()     Message to prepare for dragging.
void	propertyChange(PropertyChangeEvent e)     Property change event, presumably from the JSplitPane, will message updateOrientation if necessary.
void	setBasicSplitPaneUI(BasicSplitPaneUI newUI)     Sets the SplitPaneUI that is using the receiver.
void	setBorder(Border border)     Sets the border of this component.
void	setDividerSize(int newSize)     Sets the size of the divider to newSize.
