构造方法详细信息

Filler

@ConstructorProperties({"minimumSize","preferredSize","maximumSize"})public Filler(Dimension min,              Dimension pref,              Dimension max)

用于创建具有给定大小范围的形状的构造函数。

参数

min - 最小尺码

pref - 首选尺寸

max - 最大尺码

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。 因此，invalidate（）会向上传播，以便最终使用新大小进行布局。

参数

min - getMinimumSize的返回值

pref - getPreferredSize返回的值

max - getMaximumSize的返回值

paintComponent

protected void paintComponent(Graphics g)

这个Filler 。 如果此Filler具有UI，则此方法调用super的实现，否则如果此Filler是不透明的，则使用背景填充Graphics 。

重写：

paintComponent在类 JComponent

参数

g - 绘制到 Graphics

异常

NullPointerException - 如果 g为空

从以下版本开始：

1.6

另请参见：

JComponent.paint(java.awt.Graphics) ， ComponentUI

getAccessibleContext

public AccessibleContext getAccessibleContext()

获取与此Box.Filler关联的AccessibleContext。 对于框填充程序，AccessibleContext采用AccessibleBoxFiller的形式。 如有必要，将创建一个新的AccessibleAWTBoxFiller实例。

Specified by:

getAccessibleContext在界面 Accessible

重写：

getAccessibleContext类 Component

结果

一个AccessibleBoxFiller，用作此Box.Filler的AccessibleContext。
