请教:如何获取鼠标右击事件?

Question

我想在JTabbedPane的标签页处右击鼠标,然后弹出一个popupMenu,请高手指点!
这个问题应该涉及到mouseEvent和mouseListener,但是,JTabbedPane只有一个ChangeListener
到这儿我就不知道该怎么做了,请各位大哥帮帮忙,如能给一些代码那就更好了,先谢了!!

homesos 你能说的再详细点吗?谢谢

Answer 2

先創建一個JPopupMenu, 然後調用JTabbedPane的setComponentPopupMenu(JPopupMenu popup)方法.
你試試吧.
我覺得還是用swt/jface寫介面比較好.

JTabbedPane有关于mouse的方法（是继承的）java.lang.Object
  |
  +--java.awt.Component
        |
        +--java.awt.Container
              |
              +--javax.swing.JComponent
                    |
                    +--javax.swing.JTabbedPane
java.awt.Component：
addMouseListener, mouseDown, mouseDrag, mouseEnter, mouseExit, mouseMove, mouseUp,
