java.lang.Object java.awt.Component java.awt.Container javax.swing.JComponent javax.swing.JToolTip
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
