Doc from javax.swing.plaf.basic.BasicScrollBarUI.createPropertyChangeListener.

Creates a property change listener.

createUIback to summary
public static ComponentUI createUI(JComponent c)

Hides javax.swing.plaf.basic.BasicScrollBarUI.createUI.

Constructs a new MetalScrollBarUI instance.

Parameters
c:JComponent

a component

Returns:ComponentUI

a new MetalScrollBarUI instance

getMinimumThumbSizeback to summary
protected Dimension getMinimumThumbSize()

Overrides javax.swing.plaf.basic.BasicScrollBarUI.getMinimumThumbSize.

Doc from javax.swing.plaf.basic.BasicScrollBarUI.getMinimumThumbSize.

Returns the smallest acceptable size for the thumb. If the scrollbar becomes so small that this size isn't available, the thumb will be hidden.

Warning

the value returned by this method should not be be modified, it's a shared static constant.

getPreferredSizeback to summary
public Dimension getPreferredSize(JComponent c)

Overrides javax.swing.plaf.basic.BasicScrollBarUI.getPreferredSize.

Doc from javax.swing.plaf.basic.BasicScrollBarUI.getPreferredSize.

A vertical scrollbar's preferred width is the maximum of preferred widths of the (non null) increment/decrement buttons, and the minimum width of the thumb. The preferred height is the sum of the preferred heights of the same parts. The basis for the preferred size of a horizontal scrollbar is similar.

The preferredSize is only computed once, subsequent calls to this method just return a cached size.

protected void installDefaults()

Overrides javax.swing.plaf.basic.BasicScrollBarUI.installDefaults.

Doc from javax.swing.plaf.basic.BasicScrollBarUI.installDefaults.

Installs the defaults.

protected void installListeners()

Overrides javax.swing.plaf.basic.BasicScrollBarUI.installListeners.

Doc from javax.swing.plaf.basic.BasicScrollBarUI.installListeners.

Installs the listeners.

setThumbBoundsback to summary
protected void setThumbBounds(int x, int y, int width, int height)

Overrides javax.swing.plaf.basic.BasicScrollBarUI.setThumbBounds.

This is overridden only to increase the invalid area. This ensures that the "Shadow" below the thumb is invalidated
