public class MetalScrollButton
extends BasicArrowButton

JButton object for Metal scrollbar arrows.

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. A future release of Swing will provide support for long term persistence.

Constructor Detail

MetalScrollButton

public MetalScrollButton(int direction,
                         int width,
                         boolean freeStanding)
Method Detail

setFreeStanding

public void setFreeStanding(boolean freeStanding)

paint

public void paint(Graphics g)
Description copied from class: JComponent
This method is invoked by Swing to draw components. Applications should not invoke paint directly, but should instead use the repaint method to schedule the component for redrawing.

This method actually delegates the work of painting to three protected methods: paintComponent, paintBorder, and paintChildren. They're called in the order listed to ensure that children appear on top of component itself. Generally speaking, the component and its children should not paint in the insets area allocated to the border. Subclasses can just override this method, as always. A subclass that just wants to specialize the UI (look and feel) delegates paint method should just override paintComponent.

Overrides:
paint in class BasicArrowButton
Tags copied from class: JComponent
See Also:
JComponent.paintComponent(java.awt.Graphics), JComponent.paintBorder(java.awt.Graphics), JComponent.paintChildren(java.awt.Graphics), JComponent.getComponentGraphics(java.awt.Graphics), JComponent.repaint(long, int, int, int, int)

getPreferredSize

public Dimension getPreferredSize()
Description copied from class: JComponent
If the preferredSize has been set to a non-null value just return it. If the UI delegates getPreferredSize() method returns a non null then value return that, otherwise defer to the components layout manager.
Overrides:
getPreferredSize in class BasicArrowButton
Tags copied from class: JComponent
Returns:
the value of the preferredSize property.
See Also:
JComponent.setPreferredSize(java.awt.Dimension)

getMinimumSize

public Dimension getMinimumSize()
Description copied from class: JComponent
If the minimumSize has been set to a non-null value just return it. If the UI delegates getMinimumSize() method returns a non null value then return that, otherwise defer to the components layout manager.
Overrides:
getMinimumSize in class BasicArrowButton
Tags copied from class: JComponent
Returns:
the value of the minimumSize property.
See Also:
JComponent.setMinimumSize(java.awt.Dimension)

getMaximumSize

public Dimension getMaximumSize()
Description copied from class: JComponent
If the maximumSize has been set to a non-null value just return it. If the UI delegates getMaximumSize() method returns a non null value then return that, otherwise defer to the components layout manager.
Overrides:
getMaximumSize in class BasicArrowButton
Tags copied from class: JComponent
Returns:
the value of the maximumSize property.
See Also:
JComponent.setMaximumSize(java.awt.Dimension)

getButtonWidth

public int getButtonWidth()
