Delphi 鼠标控制函数GetCursorPos、SetCursorPos

GetCursorPos函数 获取鼠标的位置

var
   P: TPoint;
begin
   GetCursorPos(P); //获取鼠标位置
end;

SetCursorPos函数 设置鼠标的位置

var
  x,y:integer; //
begin
  x:=614; y:=282; //
  SetCursorPos(x,y); //
  Mouse_Event(MOUSEEVENTF_LEFTDOWN,0,0,0,0); //开始点击
  Mouse_Event(MOUSEEVENTF_LEFTUP,0,0,0,0); //弹出
end;

mouse_event，用于模拟鼠标动作。无返回值。参数1类型：整数型(Integer)，鼠标动作标识;参数2类型：整数型(Integer)，鼠标动作的水平坐标X;参数3类型：整数型(Integer)，鼠标动作的垂直坐标Y;参数4类型：整数型(Integer)，鼠标滚轮转动方向，若当前鼠标无滚轮动作，则取值为0;参数5在Windows SDK中的函数原型：

VOID mouse_event(

DWORD dwFlags, // flags specifying various motion/click variants 鼠标动作标识

DWORD dx, // horizontal mouse position or position change 鼠标动作的水平坐标

DWORD dy, // vertical mouse position or position change 鼠标动作垂直坐标

DWORD dwData, // amount of wheel movement 当鼠标动作标识为MOUSEEVENTF_WHEEL时，此参数为鼠标滚轮转动方向，正值表示滚轮向前旋转,远离用户;负值表示滚轮向后旋转,向用户。

DWORD dwExtraInfo // 32 bits of application-defined information 设定一个32位值用于取扩展信息

);

鼠标动作标识：

MOUSEEVENTF_MOVE = $0001; { mouse move 鼠标移动}

MOUSEEVENTF_LEFTDOWN = $0002; { left button down 左键按下}

MOUSEEVENTF_LEFTUP = $0004; { left button up 左键弹起}

MOUSEEVENTF_RIGHTDOWN = $0008; { right button down 右键按下}

MOUSEEVENTF_RIGHTUP = $0010; { right button up 右键弹起}

MOUSEEVENTF_MIDDLEDOWN = $0020; { middle button down 中间按下}

MOUSEEVENTF_MIDDLEUP = $0040; { middle button up 中键弹起}

MOUSEEVENTF_WHEEL = $0800; { wheel button rolled 滚轮移动}

MOUSEEVENTF_ABSOLUTE = $8000; { absolute move 绝对移动}

其他操作：

var
  SDC: HDC;
  SColor: COLORREF;
begin
  //鼠标移动到坐标X:20 Y:30初
  Mouse.CursorPos := Point(20, 30);

  //获取屏幕坐标X:20 Y:30初的颜色
  SDC := GetDC(0);
  SColor := GetPixel(SDC, 20, 30);
  ReleaseDC(0, SDC);

  //把取到的颜色画在屏幕上
  Canvas.Brush.Color := SColor;
  Canvas.FillRect(Rect(0, 0, 50, 50));
