java.awt.Panel

实现的所有接口

ImageObserver ， MenuContainer ， Serializable ， Accessible

已知直接子类：

Applet

public class Panel
extends Container
implements Accessible

Panel是最简单的容器类。 面板提供了一个空间，应用程序可以在其中附加任何其他组件，包括其他面板。

面板的默认布局管理器是FlowLayout布局管理器。

从以下版本开始：

1.0

构造方法详细信息

Panel

public Panel()

使用默认布局管理器创建新面板。 所有面板的默认布局管理器是FlowLayout类。

Panel

public Panel(LayoutManager layout)

使用指定的布局管理器创建新面板。

参数

layout - 此面板的布局管理器。

从以下版本开始：

1.1

方法详细信息

addNotify

public void addNotify()

创建Panel的同行。 对等体允许您修改面板的外观而不更改其功能。

重写：

addNotify在课程 Container

另请参见：

Component.isDisplayable() ， Container.removeNotify()

getAccessibleContext

public AccessibleContext getAccessibleContext()

获取与此Panel关联的AccessibleContext。 对于面板，AccessibleContext采用AccessibleAWTPanel的形式。 如有必要，将创建一个新的AccessibleAWTPanel实例。

Specified by:

getAccessibleContext在界面 Accessible

重写：

getAccessibleContext在课程 Component

结果

一个AccessibleAWTPanel，用作此Panel的AccessibleContext

从以下版本开始：

1.3
