使用mousePress()方法时出错

Question

我试图在按钮4上获得一个鼠标事件。

int moused = MouseInfo.getNumberOfButtons();

方法是5。除了按钮4(即右键单击)之外，我无法计算出任何按钮是什么；运行我得到的错误代码：

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);

您需要传递一个掩码(而不是按钮号)的原因是为了支持按钮的组合：

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

上面的掩码对应于同时按下按钮1和2。

Answer 2

问题在于使用发布按钮。

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

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

使用上面的片段，您的问题将得到解决。
