JPopupMenu弹出后不消失了
代码很简答，为什么pMenu弹出后不能消失，除非关闭程序，有什么办法在pMenu以外的任何地方点击鼠标都消失呢

private JPopupMenu pMenu;
private JMenuItem mSelectAll;
private JMenuItem mCopy;
private JMenuItem mCut;

private JMenuItem mSelectAll;
private JMenuItem mCopy;
private JMenuItem mCut;

mSelectAll.addMouseMotionListener(this);
mCopy.addMouseMotionListener(this);
mCut.addMouseMotionListener(this);

mSelectAll.addActionListener(this);
mCopy.addActionListener(this);
mCut.addActionListener(this);

pMenu.add(mSelectAll);
pMenu.add(mCopy);
pMenu.add(mCut);
pMenu.setLocation(p);
pMenu.setVisible(true);
pMenu.requestFocus();

如果没理解错的话，重写MouseListener的mouseExit方法即可，示例如上
