警告：此类的已序列化对象与以后的 Swing 版本不兼容。当前序列化支持适用于短期存储，或适用于在运行相同 Swing 版本的应用程序之间进行 RMI（Remote Method Invocation，远程方法调用）。从 1.4 版本开始，已在 java.beans 包中添加了支持所有 JavaBeans^TM 长期存储的功能。请参见 XMLEncoder。

构造方法详细信息

Box.Filler

public Box.Filler(Dimension min,
                  Dimension pref,
                  Dimension max)

使用给定的大小范围创建形状的构造方法。

参数：

min - 最小大小

pref - 首选大小

max - 最大大小

方法详细信息

changeShape

public void changeShape(Dimension min,
                        Dimension pref,
                        Dimension max)

更改此形状的大小请求。此方法使 invalidate() 向上传播，以至最终将使用新的大小进行布局。

参数：

min - 将由 getMinimumSize 返回的值

pref - 将由 getPreferredSize 返回的值

max - 将由 getMaximumSize 返回的值

getMinimumSize

public Dimension getMinimumSize()

返回组件的最小大小。

覆盖：

类 JComponent 中的 getMinimumSize

返回：

该大小

另请参见：

JComponent.setMinimumSize(java.awt.Dimension), ComponentUI

getPreferredSize

public Dimension getPreferredSize()

返回组件的首选大小。

覆盖：

类 JComponent 中的 getPreferredSize

返回：

该大小

另请参见：

JComponent.setPreferredSize(java.awt.Dimension), ComponentUI

getMaximumSize

public Dimension getMaximumSize()

返回组件的最大大小。

覆盖：

类 JComponent 中的 getMaximumSize

返回：

该大小

另请参见：

JComponent.setMaximumSize(java.awt.Dimension), ComponentUI

getAccessibleContext

public AccessibleContext getAccessibleContext()

获得与此 Box.Filler 相关联的 AccessibleContext。对于 box filler，AccessibleContext 采用 AccessibleBoxFiller 的形式。如有必要，可创建一个新的 AccessibleAWTBoxFiller 实例。

指定者：

接口 Accessible 中的 getAccessibleContext

覆盖：

类 JComponent 中的 getAccessibleContext

返回：

一个 AccessibleBoxFiller，它充当此 Box.Filler 的 AccessibleContext。
