如何模拟鼠标移动

下面是我身边的一些修改过的Win32代码：

#define WIN32_LEAN_AND_MEAN
#define _WIN32_WINNT 0x0500
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <conio.h>
#include <string.h>
#include <windows.h>

#define X 123
#define Y 123
#define SCREEN_WIDTH 1024
#define SCREEN_HEIGHT 800

void MouseSetup(INPUT *buffer)
{
    buffer->type = INPUT_MOUSE;
    buffer->mi.dx = (0 * (0xFFFF / SCREEN_WIDTH));
    buffer->mi.dy = (0 * (0xFFFF / SCREEN_HEIGHT));
    buffer->mi.mouseData = 0;
    buffer->mi.dwFlags = MOUSEEVENTF_ABSOLUTE;
    buffer->mi.time = 0;
    buffer->mi.dwExtraInfo = 0;
}

void MouseMoveAbsolute(INPUT *buffer, int x, int y)
{
    buffer->mi.dx = (x * (0xFFFF / SCREEN_WIDTH));
    buffer->mi.dy = (y * (0xFFFF / SCREEN_HEIGHT));
    buffer->mi.dwFlags = (MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE);
    SendInput(1, buffer, sizeof(INPUT));
}

void MouseClick(INPUT *buffer)
{
    buffer->mi.dwFlags = (MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTDOWN);
    SendInput(1, buffer, sizeof(INPUT));
    Sleep(10);
    buffer->mi.dwFlags = (MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTUP);
    SendInput(1, buffer, sizeof(INPUT));
}

int main(int argc, char *argv[])
{
    INPUT buffer[1];
    MouseSetup(&buffer);
    MouseMoveAbsolute(&buffer, X, Y);
    MouseClick(&buffer);
    return 0;
}

在使用之前，您需要调用MouseSetup()到每个INPUT缓冲区。

以下是针对使用Linux的用户使用Xlib的解决方案：

#include <X11/Xlib.h>
#include<stdio.h>
#include<unistd.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <X11/Xlib.h>
#include <X11/Xutil.h>
void mouseClick(int button)
{
    Display *display = XOpenDisplay(NULL);
    XEvent event;
    if(display == NULL)
    {
        fprintf(stderr, "Errore nell'apertura del Display !!!n");
        exit(EXIT_FAILURE);
    }
    memset(&event, 0x00, sizeof(event));
    event.type = ButtonPress;
    event.xbutton.button = button;
    event.xbutton.same_screen = True;
    XQueryPointer(display, RootWindow(display, DefaultScreen(display)), &event.xbutton.root, &event.xbutton.window, &event.xbutton.x_root, &event.xbutton.y_root, &event.xbutton.x, &event.xbutton.y, &event.xbutton.state);
    event.xbutton.subwindow = event.xbutton.window;
    while(event.xbutton.subwindow)
    {
        event.xbutton.window = event.xbutton.subwindow;
        XQueryPointer(display, event.xbutton.window, &event.xbutton.root, &event.xbutton.subwindow, &event.xbutton.x_root, &event.xbutton.y_root, &event.xbutton.x, &event.xbutton.y, &event.xbutton.state);
    }
    if(XSendEvent(display, PointerWindow, True, 0xfff, &event) == 0) fprintf(stderr, "Errorn");
    XFlush(display);
    usleep(100000);
    event.type = ButtonRelease;
    event.xbutton.state = 0x100;
    if(XSendEvent(display, PointerWindow, True, 0xfff, &event) == 0) fprintf(stderr, "Errorn");
    XFlush(display);
    XCloseDisplay(display);
}

int main(int argc, char * argv[]) {
    int x , y;
    x = atoi(argv[1]);
    y = atoi(argv[2]);
    Display *display = XOpenDisplay(0);
    Window root = DefaultRootWindow(display);
    XWarpPointer(display, None, root, 0, 0, 0, 0, x, y);
    mouseClick(Button1);
    XFlush(display);
    XCloseDisplay(display);
    return 0;
}

只需构建它，然后模拟点击x，y do:

$ ./a.out x y

即

$g++ -lX11 sgmousesim2.cpp
$./a.out 123 13

使用SendInput生成要模拟的输入。来自MSDN文档：

合成击键、鼠标移动和按钮单击。

我从未使用过C++。然而，有一个名为Robot的Java类能够生成鼠标事件。我在Java 1.4版本上使用过这个，但它仍然有效。我尝试了在Mac OS X中模拟物理鼠标移动的例子。它在MacOSX Lion上与Oracle Java 1.6.0_26顺利运行。Java的优点在于它是独立于平台的。

import java.awt.AWTException;
import java.awt.Robot;
public final class MovingMouseDemo
{
   public static void main(String[] args) throws AWTException
   {
     Robot robot = new Robot();
     robot.setAutoDelay(5);
     robot.setAutoWaitForIdle(true);
     //put mouse in the top left of the screen
     robot.mouseMove(0, 0);
     //wait so that you can see the result
     robot.delay(1000);
     //put the mouse 200 pixels away from the top
     //10 pixels away from the left 
     robot.mouseMove(200, 10);
     robot.delay(1000);
     robot.mouseMove(40, 130);
  }
}

您仍然可以使用JNI将其与C++绑定。

我希望它能帮助

仅靠C++无法做到这一点。它没有"鼠标"的概念，更不用说"点击"了。

你需要某种能与你的窗口系统对话的图书馆。例如，QT。然后就是搜索API并进行正确的C++调用。

使用mouse_event函数。
