ActionEvent和MouseEvent右键单击JAVA Mac [英] ActionEvent and MouseEvent right-click JAVA Mac

问题描述

我不确定这是Mac问题，还是我的代码问题。我正在创建一个按钮网格。对于每个按钮，我使用ActionEvent进行常规单击，使用MouseEvent进行右键单击。当我按CTRL-单击鼠标事件执行正常时会发生什么，但是操作甚至也会触发。有没有办法解决这个问题，同时同时使用动作和鼠标事件？相关代码：

I'm not sure if this a Mac issue, or an issue with my code. I am creating a grid of buttons. For each button I use ActionEvent for a regular click, and MouseEvent for a right click. What happens is when I CTRL-click the mouse event performs fine, however the action even also fires. Is there a way I can get around this while also using both action and mouse events? Relevant code:

查看构造函数：

for (int i = 0; i < rows; i++)
        {
            for (int j = 0; j < columns; j++)
            {
                button[i][j] = new Cell();
                button[i][j].addActionListener( new changeButtonHandler() );
                button[i][j].addMouseListener( new handleRight() );
                playArea.add(button[i][j]);

            }
        }

行动事件类：

public class changeButtonHandler implements ActionListener
    {
        /**
         * Action performed after button is clicked
         * 
         */
        @SuppressWarnings("unchecked")
        public void actionPerformed(ActionEvent e)
        {

            for (int i = 0; i < rows; i++)
            {
                for (int j = 0; j < columns; j++)
                {
                    if (button[i][j] == e.getSource())
                    {   
                    //do stuff
                        }
                        else if(button[i][j].mine==false){
                            //do other stuff
                        }   
                    }

                }
            }   
        }   
    }//end changeButtonHandler class

鼠标事件类

public class handleRight implements MouseListener {

           /**
             * Action performed after button is right-clicked
             * 
             */
        public void mouseClicked(MouseEvent e)
        {
            if (SwingUtilities.isRightMouseButton(e) || e.isControlDown())      {
                System.out.println("Right Worked");
                for (int i = 0; i < rows; i++)
                {
                    for (int j = 0; j < columns; j++)
                    {
                        if (button[i][j] == e.getSource())
                        {   
                                  //do stuff
                        }
                    }
                }
            }
        }

推荐答案

当我试图重现你的时候我自己的最小示例程序的问题，我做不到。 MouseListener在预期时工作，ActionListener在预期时工作：

When I tried to reproduce your problem with my own minimal example program, I couldn't. The MouseListener worked when expected and the ActionListener worked when expected:

import java.awt.event.*;
import javax.swing.*;

public class TestButtonRightClick {
   public static void main(String[] args) {
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            JButton button = new JButton("Test Me!");
            button.addActionListener(new ActionListener() {

               @Override
               public void actionPerformed(ActionEvent e) {
                  System.out.println("ActionListener invoked");
               }
            });
            button.addMouseListener(new MouseAdapter() {
               @Override
               public void mousePressed(MouseEvent e) {
                  if (e.getButton() == MouseEvent.BUTTON3) {
                     System.out.println("Right Button Pressed");
                  }
               }
            });

            JPanel panel = new JPanel();
            panel.add(button);
            JOptionPane.showMessageDialog(null, panel);
         }
      });
   }
}

编辑：为什么使用SwingUtilities而不是 e.getMouseButton（）？

// ? SwingUtilities
if (SwingUtilities.isRightMouseButton(e) || e.isControlDown())      {

注意，如需进一步的帮助，请考虑创建自己的最小示例程序，类似于上面的内容。

Note, for further help, consider creating your own minimal example program similar to mine above.

检查ctrl键的状态按下按钮，检查ActionListener中ActionEvent的修饰符：

To check the state of the ctrl key on button press, check the modifiers of the ActionEvent in your ActionListener:

           @Override
           public void actionPerformed(ActionEvent e) {
              if ((e.getModifiers() & ActionEvent.CTRL_MASK) == ActionEvent.CTRL_MASK) {
                 System.out.println("control pressed");
              } else {
                 System.out.println("ActionListener invoked");
              }
           }
        });
