右键单击JButton [英] Right click on JButton

问题描述

我正在尝试用Java编写Minesweeper克隆以获得乐趣。我有一个JButtons网格，我会更改标签以表示危险计数，标记等。

I am trying to write a Minesweeper clone in Java for fun. I have a grid of JButtons whose labels I will change to represent the danger count, flags, etc.

我的问题是，我不知道如何正确单击JButton按下按钮。我已经完成了以下操作：

My problem is, I don't know how to get a right click on a JButton to depress the button. I've done the following:

button.addMouseListener(new MouseAdapter(){
    public void mouseClicked(MouseEvent e){
        boolean mine = field.isMine(x, y);
        if (e.isPopupTrigger()) {
            button.setText("F");
        }
        else {
            if (mine) {
                button.setText("X");
            }
        }
    }
});

这似乎根本不起作用; F从未显示，只有X部分。但更重要的是，这对于按下按钮没有任何作用。

This doesn't seem to be working at all; the "F" is never shown, only the "X" part. But more importantly, this does nothing for depressing the button.

编辑：Mac上有弹出触发器发生在mousePress上，而不是mouseClick。

Macs have popup trigger happen on mousePress, not mouseClick.

编辑：这是我根据接受的答案制定的解决方案：

Here's the solution I worked out based off of accepted answer:

button.addMouseListener(new MouseAdapter(){
            boolean pressed;

            @Override
            public void mousePressed(MouseEvent e) {
                button.getModel().setArmed(true);
                button.getModel().setPressed(true);
                pressed = true;
            }

            @Override
            public void mouseReleased(MouseEvent e) {
                //if(isRightButtonPressed) {underlyingButton.getModel().setPressed(true));
                button.getModel().setArmed(false);
                button.getModel().setPressed(false);

                if (pressed) {
                    if (SwingUtilities.isRightMouseButton(e)) {
                        button.setText("F");
                    }
                    else {
                        button.setText("X");
                    }
                }
                pressed = false;

            }

            @Override
            public void mouseExited(MouseEvent e) {
                pressed = false;
            }

            @Override
            public void mouseEntered(MouseEvent e) {
                pressed = true;
            }                    
        });
        add(button);

推荐答案

右键单击无法按下按钮。将这样的行添加到鼠标监听器

Button can't be pressed by right click. Add such a lines to you mouse listener

mousePressed：

mousePressed:

if(isRightButtonPressed) {underlyingButton.getModel().setPressed(true));

mouseReleased：

mouseReleased:

if(needReset) {underlyingButton.getModel().setPressed(false));

或者做任何想做的事。
