getPreferredSize

public Dimension getPreferredSize(JComponent c)

Class is disabled.

Description copied from class: BasicScrollBarUI

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.

Overrides:

getPreferredSize in class BasicScrollBarUI

Parameters:

c - the JScrollBar that's delegating this method to us

Returns:

the preferred size of a Basic JScrollBar

See Also:

BasicScrollBarUI.getMaximumSize(javax.swing.JComponent), ComponentUI.getMinimumSize(javax.swing.JComponent)

createDecreaseButton

protected JButton createDecreaseButton(int orientation)

Class is disabled.

Returns the view that represents the decrease view.

Overrides:

createDecreaseButton in class BasicScrollBarUI

createIncreaseButton

protected JButton createIncreaseButton(int orientation)

Class is disabled.

Returns the view that represents the increase view.

Overrides:

createIncreaseButton in class BasicScrollBarUI

paintTrack

protected void paintTrack(Graphics g,
                          JComponent c,
                          Rectangle trackBounds)

Class is disabled.

Overrides:

paintTrack in class BasicScrollBarUI

paintThumb

protected void paintThumb(Graphics g,
                          JComponent c,
                          Rectangle thumbBounds)

Class is disabled.

Overrides:

paintThumb in class BasicScrollBarUI

getMinimumThumbSize

protected Dimension getMinimumThumbSize()

Class is disabled.

Description copied from class: BasicScrollBarUI

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.

Overrides:

getMinimumThumbSize in class BasicScrollBarUI

Returns:

The smallest acceptable size for the thumb.

See Also:

BasicScrollBarUI.getMaximumThumbSize()

setThumbBounds

protected void setThumbBounds(int x,
                              int y,
                              int width,
                              int height)

Class is disabled.

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

Overrides:

setThumbBounds in class BasicScrollBarUI

BasicScrollBarUI.getThumbBounds()
