Class JSeparator

java.lang.Object

java.awt.Component

java.awt.Container

javax.swing.JComponent

javax.swing.JSeparator

All Implemented Interfaces:

ImageObserver， MenuContainer， Serializable， Accessible， SwingConstants

已知直接子类：

JPopupMenu.Separator， JToolBar.Separator

public class JSeparator
extends JComponent
implements SwingConstants, Accessible

JSeparator实施分隔线-最常用的菜单项被分解成逻辑分组之间的分压器提供了一个通用的组件。而不是直接使用 JSeparator，您可以使用 JMenu或 JPopupMenu addSeparator方法创建和添加分隔。 JSeparators也可以用于其他GUI无论视觉分频器是有用的。

更多的信息和例子见How to Use Menus，java教程中的一部分。

警告： Swing是线程不安全的。更多信息见Swing's Threading Policy。

警告：序列化该类的对象与以后的Swing版本不兼容。当前的序列化支持适用于短期贮藏或RMI运行相同Swing版本的应用程序之间。为1.4，为所有JavaBeans™长期存储的支持已被添加到java.beans包。请看XMLEncoder。

Constructor Detail

JSeparator

public JSeparator()

创建一个新的水平分隔符。

JSeparator

public JSeparator(int orientation)

用指定的水平或垂直方向创建一个新的分隔符。

参数

orientation指定 SwingConstants.HORIZONTAL或 SwingConstants.VERTICAL整数

异常

IllegalArgumentException -如果 orientation既 SwingConstants.HORIZONTAL也 SwingConstants.VERTICAL

方法详细信息

getUI

public SeparatorUI getUI()

返回呈现此组件的L和F对象。

结果

的separatorui对象，使得这部分

setUI

public void setUI(SeparatorUI ui)

设置呈现此组件的“L”和F对象。

参数

ui - separatorui L和F的对象

另请参见：

UIDefaults.getUI(javax.swing.JComponent)

updateUI

public void updateUI()

重置UI属性从目前看价值和感觉。

重写：

updateUI 方法重写，继承类 JComponent

另请参见：

JComponent.updateUI()

getUIClassID

public String getUIClassID()

返回呈现此组件的“L”和“F”类的名称。

重写：

getUIClassID 方法重写，继承类 JComponent

结果

字符串“separatorui”

另请参见：

JComponent.getUIClassID()， UIDefaults.getUI(javax.swing.JComponent)

getOrientation

public int getOrientation()
