java.lang.Objectjava.awt.Component
public class JToolTip
用来显示 Component 的“提示”。通常，组件提供 api，从而将使用 ToolTip 的过程自动化。例如，任何 Swing 组件都可以使用 JComponent setToolTipText 方法来指定一个标准的工具提示文本。需要创建自定义 ToolTip 显示的组件可以重写 JComponent 的 createToolTip 方法，并使用此类的一个子类。
有关更多文档，请参阅 The Java Tutorial 中的 How to Use Tool Tips 一节。
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：此类的已序列化对象与以后的 Swing 版本不兼容。当前序列化支持适用于短期存储，或适用于在运行相同 Swing 版本的应用程序之间进行 RMI（Remote Method Invocation，远程方法调用）。从 1.4 版本开始，已在 java.beans 包中添加了支持所有 JavaBeansTM 长期存储的功能。请参见 XMLEncoder。
