UIScrollBarUI

java.lang.Object
- javax.swing.plaf.ComponentUI
- - javax.swing.plaf.ScrollBarUI
  - - com.fr.design.gui.iscrollbar.UIScrollBarUI

所有已实现的接口:

java.awt.LayoutManager, javax.swing.SwingConstants
```
public class UIScrollBarUI
extends javax.swing.plaf.ScrollBarUI
implements java.awt.LayoutManager, javax.swing.SwingConstants
```
Like BasicScrollBarUI,but without two buttons

  - getPreferredSize
```
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.

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

  - getMinimumThumbSize
```
protected java.awt.Dimension getMinimumThumbSize()

    Return 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.
    
    返回:
    The smallest acceptable size for the thumb.

    Return the largest acceptable size for the thumb. To create a fixed size thumb one make this method and getMinimumThumbSize return the same value.
    Warning : the value returned by this method should not be be modified, it's a shared static constant.
