Class Overview

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.

protected JSplitPane splitPane

JSplitPane the receiver is contained in.

protected BasicSplitPaneUI splitPaneUI

UI this instance was created from.

Public Constructors

public BasicSplitPaneDivider (BasicSplitPaneUI ui)

Creates an instance of BasicSplitPaneDivider. Registers this instance for mouse events and mouse dragged events.

Public Methods

public BasicSplitPaneUI getBasicSplitPaneUI ()

Returns the SplitPaneUI the receiver is currently in.

public Border getBorder ()

Returns the border of this component or null if no border is currently set.

Returns

the border object for this component

public int getDividerSize ()

Returns the size of the divider, that is the width if the splitpane is HORIZONTAL_SPLIT, or the height of VERTICAL_SPLIT.

public Insets getInsets ()

If a border has been set on this component, returns the border's insets, else calls super.getInsets.

Returns

the value of the insets property.

public Dimension getMinimumSize ()

Returns dividerSize x dividerSize

Returns

an instance of Dimension that represents the minimum size of this container.

public Dimension getPreferredSize ()

Returns dividerSize x dividerSize

Returns

an instance of Dimension that represents the preferred size of this container.

public boolean isMouseOver ()

Returns whether or not the mouse is currently over the divider

Returns

whether or not the mouse is currently over the divider

public void paint (Graphics g)

Paints the divider.

Parameters

g	the specified Graphics window

public void propertyChange (PropertyChangeEvent e)
