在Windows中模拟鼠标按钮单击 [英] Simulating a mouse button click in Windows

问题描述

我使用QT在C ++中编写远程桌面克隆。到目前为止，我可以移动鼠标光标周围罚款。 QT有一个很好的setPos函数。但是，我对于用于模拟鼠标按钮点击的API /库有点失落。

I'm writing Remote Desktop clone in C++ using QT. So far I'm able to move the mouse cursor around fine. QT has a nice setPos function for that. However, I'm a bit lost as to what API/Library to use for simulating mouse button clicks.

我知道的一种方法是发送WM_事件）到使用窗口的HWND的窗口。然而，我希望有一个更显着的方法来完全控制鼠标。有没有其他方法告诉操作系统鼠标左键已经点击？

One method I'm aware of is to send the WM_(event) to a window using the window's HWND. However, I was hoping there was a more salient method for taking complete control over a mouse. Is there any other way to tell the operating system that the left mouse button has been clicked?

谢谢。

推荐答案

这是C＃，但可能会帮助你得到一个想法：

This is in C#, but might help you to get an idea:

[DllImport("user32.dll",CharSet=CharSet.Auto, CallingConvention=CallingConvention.StdCall)]
   public static extern void mouse_event(long dwFlags, long dx, long dy, long cButtons, long dwExtraInfo);

   private const int MOUSEEVENTF_LEFTDOWN = 0x02;
   private const int MOUSEEVENTF_LEFTUP = 0x04;
   private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
   private const int MOUSEEVENTF_RIGHTUP = 0x10;

   public void DoMouseClick()
   {
      int X = Cursor.Position.X;
      int Y = Cursor.Position.Y;
      mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0);
   }
