public class JToolTipextends JComponentimplements Accessible
用于显示组件的“提示”。 通常组件提供api以自动化使用ToolTip
的过程。 例如,任何Swing组件都可以使用JComponent
setToolTipText
方法指定标准工具提示的文本。 想要创建自定义ToolTip
显示的组件可以覆盖JComponent
的createToolTip
方法并使用此类的子类。有关更多文档,请参阅The Java Tutorial中的 How to Use Tool Tips 。
警告: Swing不是线程安全的。 有关更多信息,请参阅Swing's Threading Policy 。
警告:此类的序列化对象与以后的Swing版本不兼容。 当前的序列化支持适用于运行相同版本Swing的应用程序之间的短期存储或RMI。 从1.4开始,
java.beans
软件包中添加了对所有JavaBeansjava.beans
