构造方法详细信息
-
Filler
@ConstructorProperties({"minimumSize","preferredSize","maximumSize"}) public Filler(Dimension min, Dimension pref, Dimension max)
创建具有给定大小范围的形状的构造函数。- 参数
-
min
- 最小尺寸 -
pref
- 首选尺寸 -
max
- 最大尺寸
-
-
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,从而最终使用新的大小进行布局。- 参数
-
min
- getMinimumSize返回的值 -
pref
- getPreferredSize返回的值 -
max
- getMaximumSize返回的值
-
paintComponent
protected void paintComponent(Graphics g)
Filler
这Filler
。 如果这个Filler
有一个UI,这个方法调用super的实现,否则如果这个Filler
是不透明的,Graphics
是使用背景填充的。- 重写:
-
paintComponent
在JComponent
- 参数
-
g
- 要绘画的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相关联的AccessibleContext。 对于盒填充,AccessibleContext采用AccessibleBoxFiller的形式。 如有必要,将创建一个新的AccessibleAWTBoxFiller实例。- Specified by:
-
getAccessibleContext
在接口Accessible
- 重写:
-
getAccessibleContext
在Component
- 结果
- 一个AccessibleBoxFiller作为这个Box.Filler的AccessibleContext。
