Question

我想从数据库中获取数据并在jPopupMenu中显示它们，当点击弹出菜单中的菜单项时，想要打印它的text.i找到了一些教程，但我失败了。基本上我是什么＆＃39;我正在以编程方式将manuitem添加到jpopupmenu并且我做了它.problem是如何从jpopupmenu获取选定值。例如我有popupmenu有两个菜单项和manuitems的文本是＆＃34; menutext1＆＃34;和＃34; menutext2＆＃34;。如果manuitem1被点击，我想打印menutext1。我想将动作监听器添加到jpopupmenu或每个菜单项？

while(rs1.next()){
   jPopupMenu1.add(new JMenuItem(rs1.getString("name")));
   jPopupMenu1.show(jPanel25, 40, 114);
}

您可以为每个菜单项添加一个动作侦听器：

ActionListener menuListener = new ActionListener() {
  public void actionPerformed(ActionEvent event) {
    System.out.println("Popup menu item ["
        + event.getActionCommand() + "] was pressed.");
  }
};

while(rs1.next()){
  JMenuItem item = new JMenuItem(rs1.getString("name"));
  item.addActionListener(menuListener);
  jPopupMenu1.add(item);
}

从jpopupmenu中获取选定的值
