Question

我试图在按钮4上使用鼠标事件。使用

时返回的值

int moused = MouseInfo.getNumberOfButtons();

方法是5.我无法弄清楚按钮4之外的任何按钮是否是右键;运行代码我得到这个错误：

Exception in thread "main" java.lang.IllegalArgumentException: Invalid combinati
on of button flags
        at java.awt.Robot.checkButtonsArgument(Robot.java:324)
        at java.awt.Robot.mousePress(Robot.java:260)
        at RobotExp4.main(RobotExp4.java:23)

import java.awt.*;
import java.awt.event.KeyEvent;
public class RobotExp4{
public static void main(String [] args){
try{
    Robot robot = new Robot();
    System.out.println("7 Seconds after this message appears the robot will start to open a browser and make a search.");
    robot.delay(7000);
    robot.keyPress(KeyEvent.VK_WINDOWS);
    robot.keyRelease(KeyEvent.VK_WINDOWS);
    robot.delay(1000);
    robot.keyPress(KeyEvent.VK_C);
    robot.keyRelease(KeyEvent.VK_C);
    robot.delay(150);
    robot.keyPress(KeyEvent.VK_M);
    robot.keyRelease(KeyEvent.VK_M);
    robot.delay(150);
    robot.keyPress(KeyEvent.VK_D);
    robot.keyRelease(KeyEvent.VK_D);
    robot.delay(5000);
    robot.mouseMove(1340, 192);
    robot.delay(200);
    robot.mousePress(5);
    robot.delay(75);
    robot.mouseRelease(5);

}catch(AWTException e){
    e.printStackTrace();        
}
}
}

Answer 1

您需要传递mousePress调用InputEvent.getMaskForButton的结果，如下所示：

int mask4 = InputEvent.getMaskForButton(4);
robot.mousePress(mask4);
robot.delay(75);
robot.mouseRelease(mask4);

您需要传递遮罩而不是按钮编号的原因是支持按钮组合：

int mask1_and_2 = InputEvent.getMaskForButton(1) | InputEvent.getMaskForButton(2);

上面的面具对应于同时按下按钮1和。

Answer 2

问题在于使用释放按钮。

Robot autoPlay = new Robot();
autoPlay.setAutoDelay(500);

autoPlay.mousePress(InputEvent.BUTTON3_MASK);
autoPlay.mouseRelease(InputEvent.BUTTON3_MASK);

使用上面的代码段，您的问题就会解决。

使用mousePress（）方法时出错
