如何在没有覆盖实际鼠标的情况下在任何Java组件上单击鼠标 [英] How to mouse click on any java component without actual mouse being overridden

问题描述

当前，为了模拟我的应用程序中的鼠标单击，我使用Java的Robot类.似乎使用桌面作为边界/网格来了解Point在屏幕上的映射位置.

Currently to simulate mouse clicks in my application I use the Robot class of Java. It seems to use the desktop as bounds/grid for knowing where the Point maps out to on the screen.

示例:

Robot bot = new Robot();
bot.mouseMove(1099,22); //Manually collected point..
bot.delay(100);
bot.mousePress(InputEvent.BUTTON1_MASK);
bot.mouseRelease(InputEvent.BUTTON1_MASK);

目标:

机器人强制使用鼠标/光标，我希望能够在我的计算机上执行其他操作，而此代码仅在对其进行编程的Java应用程序上单击即可运行.

Robot forces my mouse/cursor to be used, I want to be able to do other things on my computer while this code runs doing clicks on only my Java application where I have programmed it to.

是否可以使用JNA做到这一点?除了Windows之外，不关心是否支持其他任何操作系统，但是由于遗留技术的缘故，仍需要成为Java应用程序.

Is there a way to do this with JNA? Am not concerned to supporting any Operating System other then windows but still needs to be a Java application due to legacy technologies.

推荐答案

以下代码单击相对于target的(x，y)处的target组件.

The following code clicks on the target Component at (x, y) relative to target.

private static void click(Component target, int x, int y)
{
   MouseEvent press, release, click;
   Point point;
   long time;

   point = new Point(x, y);

   SwingUtilities.convertPointToScreen(point, target);

   time    = System.currentTimeMillis();
   press   = new MouseEvent(target, MouseEvent.MOUSE_PRESSED,  time, 0, x, y, point.x, point.y, 1, false, MouseEvent.BUTTON1);
   release = new MouseEvent(target, MouseEvent.MOUSE_RELEASED, time, 0, x, y, point.x, point.y, 1, false, MouseEvent.BUTTON1);
   click   = new MouseEvent(target, MouseEvent.MOUSE_CLICKED,  time, 0, x, y, point.x, point.y, 1, false, MouseEvent.BUTTON1);

   target.dispatchEvent(press);
   target.dispatchEvent(release);
   target.dispatchEvent(click);
}
