C# 在按键上移动窗口+；鼠标（如linux ALT+；鼠标按下）

简单地说，我想移动一个按ALT+鼠标的windows，就像linux操作系统一样（ALT+拖动）

是否可以通过单击将win32 api（移动api）传递给感兴趣的windows

我有一个windows服务钩子键按下（在特定的ALT按钮）。 当按下ALT键并验证鼠标按下事件时，我想将窗口移动到任意位置，而不仅仅是在标题栏上

目前，我以以下方式移动窗体窗口：

using System.Runtime.InteropServices;

[DllImport( "user32.dll", CharSet = CharSet.Auto, SetLastError = false )]
static extern IntPtr SendMessage( IntPtr hWnd, uint Msg, int wParam, int lParam );
[DllImportAttribute( "user32.dll", CharSet = CharSet.Auto, SetLastError = false )]
public static extern bool ReleaseCapture();

private void Form1_MouseDown( object sender, MouseEventArgs e )
{
  ReleaseCapture();
  SendMessage( this.Handle, 0xa1, 0x2, 0 );
}

如何通过单击并在调用SendMessage（）后获取特定窗口的windows句柄

有可能吗？

您可以通过捕获Windows发送的WM_NCHITTEST消息来查看单击了窗口的哪个区域。您可以通过返回HTCAPTION来愚弄它，它将尽职尽责地执行您通常在单击窗口标题时获得的鼠标操作。包括移动窗户。将此代码粘贴到表单中：

    protected override void WndProc(ref Message m) {
        base.WndProc(ref m);
        // Trap WM_NCHITTEST when the ALT key is down
        if (m.Msg == 0x84 && (Control.ModifierKeys == Keys.Alt)) {
            // Translate HTCLIENT to HTCAPTION
            if (m.Result == (IntPtr)1) m.Result = (IntPtr)2;
        }
    }

我自己解决了这个问题，从我自己的计算中得出了一些有趣的东西，对我来说非常适合，适用于任何窗口（任何活动前景窗口）。有点长，但如果你按照评论进行操作，就很容易理解，希望有帮助：） 它的工作方式是按某个注册的组合键，如Ctrl+Alt+M 鼠标会停留在一个活动窗口的中心，你移动鼠标，窗口跟随它，再次按下相同的组合键，释放，不需要鼠标点击或其他任何操作

public void MoveWindow_AfterMouse()
    {
      // 1- get a handle to the foreground window (or any window that you want to move).
      // 2- set the mouse pos to the window's center.
      // 3- let the window move with the mouse in a loop, such that:
      //    win(x) = mouse(x) - win(width)/2   
      //    win(y) = mouse(y) - win(height)/2
      // This is because the origin (point of rendering) of the window, is at its top-left corner and NOT its center!

      // 1- 
      IntPtr hWnd = WinAPIs.GetForegroundWindow();

      // 2- Then:
      // first we need to get the x, y to the center of the window.
      // to do this, we have to know the width/height of the window.
      // to do this, we could use GetWindowRect which will give us the coords of the bottom right and upper left corners of the window,
      // with some math, we could deduce the width/height of the window.
      // after we do that, we simply set the x, y coords of the mouse to that center.
      RECT wndRect = new RECT();
      WinAPIs.GetWindowRect(hWnd, out wndRect);
      int wndWidth = wndRect.right - wndRect.left;
      int wndHeight = wndRect.bottom - wndRect.top; // cuz the more you go down, the more y value increases.
      Point wndCenter = new Point(wndWidth / 2, wndHeight / 2); // this is the center of the window relative to itself.
      WinAPIs.ClientToScreen(hWnd, out wndCenter); // this will make its center relative to the screen coords.
      WinAPIs.SetCursorPos(wndCenter.X, wndCenter.Y);

      // 3- Moving :)))
      while (true)
      {
        Point cursorPos = new Point();
        WinAPIs.GetCursorPos(out cursorPos);
        int xOffset = cursorPos.X - wndWidth / 2;
        int yOffset = cursorPos.Y - wndHeight / 2;
        WinAPIs.MoveWindow(hWnd, xOffset, yOffset, wndWidth, wndHeight, true);
        Thread.Sleep(25);
      }
    }

现在：

int moveCommandToggle = 0;
protected override void WndProc(ref Message m)
{
   if (m.Msg == 0x0312)
   {
     int keyID = m.WParam.ToInt32();
     if(keyID == some_key_combo_you_registered_for_the_moving)
     {
         if (moveCommandToggle++ % 2 == 0)
         {
            mover = new Thread(() => MoveWindow_AfterMouse());
            mover.Start();
         }
         else mover.Abort();
      }
    }
 }

如果您想了解RECT：

  public struct RECT
  {
    public int left;    // xCoor of upper left corner.
    public int top;     // yCoor of upper left corner.
    public int right;   // xCoor of lower right corner.
    public int bottom;  // yCoor of lower right corner.
  };

WinAPI只是一个静态类，我在其中做了DllImports。
