Class JToolTip

java.lang.Object

java.awt.Component

java.awt.Container

javax.swing.JComponent

javax.swing.JToolTip

All Implemented Interfaces:

ImageObserver， MenuContainer， Serializable， Accessible

public class JToolTip
extends JComponent
implements Accessible

用于显示一个组件的“提示”。典型的组件提供的API使用 ToolTips过程自动化。例如，任何Swing组件可以使用 JComponent setToolTipText方法指定一个标准的工具提示文本。的一个组成部分，要创建一个自定义的 ToolTip显示可以重写 JComponent的 createToolTip方法和使用该类的子类。

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

JToolTip

public JToolTip()

创建一个工具提示。

方法详细信息

getUI

public ToolTipUI getUI()

返回呈现此组件的L和F对象。

结果

的 ToolTipUI对象，使得这部分

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“ToolTipUI”

另请参见：

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