Java 获取鼠标位置

Get Mouse Position

提问by Martin Trigaux

I would like to simulate a natural mouse movement in Java (going from here to there pixel by pixel). To do that I need to know the starting coordinates.

我想用 Java 模拟一个自然的鼠标移动（从这里到那里一个像素一个像素）。为此，我需要知道起始坐标。

I've found the method event.getX() and event.getY() but I need an event...

我找到了 event.getX() 和 event.getY() 方法，但我需要一个事件...

How can I know the positions without doing anything (or something not visible)?

我如何在不做任何事情（或不可见的事情）的情况下知道位置？

Thank you

谢谢

MouseInfo.getPointerInfo().getLocation()might be helpful. It returns a Pointobject corresponding to current mouse position.

MouseInfo.getPointerInfo().getLocation()可能会有所帮助。它返回一个与当前鼠标位置对应的Point对象。

If you're using Swing as your UI layer, you can use a Mouse-Motion Listenerfor this.

如果您使用 Swing 作为 UI 层，则可以为此使用鼠标运动侦听器。

Try looking at the java.awt.Robot class. It allows you to move the mouse programatically.

尝试查看 java.awt.Robot 类。它允许您以编程方式移动鼠标。

If you're using SWT, you might want to look at adding a MouseMoveListener as explained here.

如果您使用SWT，你可能想看看添加一个MouseMoveListener作为解释在这里。

PointerInfo a = MouseInfo.getPointerInfo();
Point b = a.getLocation();
int x = (int) b.getX();
int y = (int) b.getY();
System.out.print(y + "jjjjjjjjj");
System.out.print(x);
Robot r = new Robot();
r.mouseMove(x, y - 50);

In SWT you need not be in a listener to get at the mouse location. The Display object has the method getCursorLocation().

在 SWT 中，您无需在侦听器中即可获得鼠标位置。Display 对象具有方法getCursorLocation()。

In vanilla SWT/JFace, call Display.getCurrent().getCursorLocation().

在原版 SWT/JFace 中，调用Display.getCurrent().getCursorLocation().

In an RCP application, call PlatformUI.getWorkbench().getDisplay().getCursorLocation().

在 RCP 应用程序中，调用PlatformUI.getWorkbench().getDisplay().getCursorLocation().

For SWT applications, it is preferable to use getCursorLocation()over the MouseInfo.getPointerInfo()that others have mentioned, as the latter is implemented in the AWT toolkit that SWT was designed to replace.

对于SWT应用中，优选使用getCursorLocation()过MouseInfo.getPointerInfo()，其他人已经提到的那样，因为后者在AWT工具包，SWT被设计用来替换实现。

In my scenario, I was supposed to open a dialog box in the mouse position based on a GUI operation done with the mouse. The following code worked for me:

在我的场景中，我应该根据使用鼠标完成的 GUI 操作在鼠标位置打开一个对话框。以下代码对我有用：

    public Object open() {
    //create the contents of the dialog
    createContents();
    //setting the shell location based on the curent position
    //of the mouse
    PointerInfo a = MouseInfo.getPointerInfo();
    Point pt = a.getLocation();
    shellEO.setLocation (pt.x, pt.y);

    //once the contents are created and location is set-
    //open the dialog
    shellEO.open();
    shellEO.layout();
    Display display = getParent().getDisplay();
    while (!shellEO.isDisposed()) {
        if (!display.readAndDispatch()) {
            display.sleep();
        }
    }
    return result;
}

I am doing something like this to get mouse coordinates using Robot, I use these coordinates further in few of the games I am developing:

我正在做这样的事情来使用 Robot 获取鼠标坐标，我在我正在开发的一些游戏中进一步使用这些坐标：

public class ForMouseOnly {
    public static void main(String[] args) throws InterruptedException {
        int x = MouseInfo.getPointerInfo().getLocation().x;
        int y = MouseInfo.getPointerInfo().getLocation().y;
        while (true) {

            if (x != MouseInfo.getPointerInfo().getLocation().x || y != MouseInfo.getPointerInfo().getLocation().y) {
                System.out.println("(" + MouseInfo.getPointerInfo().getLocation().x + ", "
                        + MouseInfo.getPointerInfo().getLocation().y + ")");
                x = MouseInfo.getPointerInfo().getLocation().x;
                y = MouseInfo.getPointerInfo().getLocation().y;
            }
        }
    }
}
