问题描述

我想在NetBeans IDE中向JTable添加一个右键单击popupmenu(好像一个简单的任务……大声笑)

I want to add a right click popupmenu to a JTable in NetBeans IDE (seems like a simple task... lol)

我想让它部分起作用

在表单中添加弹出菜单
将菜单项添加到弹出菜单
转到JTable的属性
单击绑定选项卡
将ComponentPopupMenu值设置为我的弹出菜单

但这仅部分起作用.现在，当我右键单击Table时，会弹出菜单，但是JTable中的选定行不会更改.因此，在调用menuitem的actionPerformed时，我不知道单击了JTable中的哪一行.

But this only partly works.Now I when I right click on the Table the menu pops up, but the selected row in the JTable does not change. So in when the menuitem's actionPerformed is called I have no idea what row in the JTable was clicked on.

我怎么能得到这个?还是在netbeans中有更简单的方法来做到这一点?

How can I get this? or is there an easier way to do this in netbeans?

我知道还有其他方法(在代码中)，但是我更喜欢使用netbeans GUI构建器.

I know there are others ways of doing this (in code), but I would prefer to use netbeans GUI builder.

以前有人做过吗?

感谢您的帮助！

推荐答案

为什么要依靠IDE为您生成代码?当您转移到另一个IDE并必须学习如何实现该想法时会发生什么?了解如何编写自己的代码，那么IDE无关紧要:

Why do you rely on an IDE to generate code for you? What happens when you move to a different IDE and you have to learn how to do it for that ide? Learn how to write your own code then the IDE doesn't matter:

table.addMouseListener( new MouseAdapter()
{
    public void mouseReleased(MouseEvent e)
    {
        if (e.isPopupTrigger())
        {
            JTable source = (JTable)e.getSource();
            int row = source.rowAtPoint( e.getPoint() );
            int column = source.columnAtPoint( e.getPoint() );

            if (! source.isRowSelected(row))
                source.changeSelection(row, column, false, false);

            popup.show(e.getComponent(), e.getX(), e.getY());
        }
    }
});
