Method Detail

• createUI

  public static ComponentUI createUI(JComponent c)

• installListeners

• getPreferredSize

  public Dimension getPreferredSize(JComponent c)

  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

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

• createDecreaseButton

  protected JButton createDecreaseButton(int orientation)

  Returns the view that represents the decrease view.

• createIncreaseButton

  protected JButton createIncreaseButton(int orientation)

  Returns the view that represents the increase view.

• paintTrack

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

• paintThumb

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

• getMinimumThumbSize

  protected Dimension getMinimumThumbSize()

  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.

  BasicScrollBarUI.getMaximumThumbSize()

• setThumbBounds

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

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

  setThumbBounds in class  BasicScrollBarUI
