| public java.awt.Dimension | getPreferredSize(javax.swing.JComponent c)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.
