java程序如何添加鼠标右键功能，使右键点击到某个item时，使显示的菜单里面包含删除等功能，像QQ一样~~~

Answer 1

这是我在一个JTable中单击又键弹出的popmenu的部分代码;
programTable.addMouseListener(new MouseAdapter() {
public void mousePressed(MouseEvent e) {
showPopup(e);
}

public void mouseReleased(MouseEvent e) {
showPopup(e);
}

private void showPopup(MouseEvent e) {
if (e.isPopupTrigger()) {
popup.show(e.getComponent(), e.getX(), e.getY());
int selRow = programTable.rowAtPoint(e.getPoint());
programTable.setRowSelectionInterval(selRow, selRow);
}
}
});
