构造方法详细信息

Panel

public Panel()
使用默认的布局管理器创建新面板。所有面板的默认布局管理器都是 FlowLayout 类。


Panel

public Panel(LayoutManager layout)
创建具有指定布局管理器的新面板。

参数:
layout - 此面板的布局管理器。
从以下版本开始:
JDK1.1
方法详细信息

addNotify

public void addNotify()
创建 Panel 的同位体。此同位体允许修改面板的外观而不会更改其功能。

覆盖:
Container 中的 addNotify
另请参见:
Component.isDisplayable(), Container.removeNotify()

getAccessibleContext

public AccessibleContext getAccessibleContext()
获取与 Panel 相关的 AccessibleContext。对于面板,AccessibleContext 采用 AccessibleAWTPanel 的形式。如有必要,则创建一个新的 AccessibleAWTPanel 实例。

指定者:
接口 Accessible 中的 getAccessibleContext
覆盖:
Component 中的 getAccessibleContext
返回:
一个 AccessibleAWTPanel,它作为此 Panel 的 AccessibleContext
