# Win32API应该可以被多种开发语言所调用，主要用来操作MS的。

class Cursor

M0USEEVENTF_LEFTDOWN = 2 # 鼠标左键按下键值

MOUSEEVENTF_LEFTUP = 4 # 鼠标左键松开键值

MOUSEEVENTF_RIGHTDOWN = 0x0008 #右键

MOUSEEVENTF_RIGHTUP = 0x0010

# 初始化
def initialize
      # 调用user32.dll的GetCursorPos(得到鼠标坐标)函数
      @getCursorPos = Win32API.new("user32","GetCursorPos",['P'],'V')
      # 调用user32.dll的GetCursorPos(得到鼠标坐标)函数
      @setCursorPos = Win32API.new("user32","SetCursorPos",['i']*2,'V')
      # 调用user32.dll的mouse_event(鼠标事件,如点击)函数
      @mouse_event = Win32API.new("user32","mouse_event",['L']*5,'V')
end

# 获得鼠标坐标
def pos
      lpPoint ="\0"*8
      @getCursorPos.Call(lpPoint)
      x,y = lpPoint.unpack("LL")
      return [x,y]
end

# 设定鼠标坐标
def pos=(xy)
      @setCursorPos.Call(xy[0],xy[1])
end

# 按下鼠标左键
def leftdown
      @mouse_event.Call(M0USEEVENTF_LEFTDOWN,0,0,0,0)
end

# 松开鼠标左键
def leftup
       @mouse_event.Call(MOUSEEVENTF_LEFTUP,0,0,0,0)
end

# 点击鼠标左键(按下提起)
def click
      leftdown
      leftup
    end

end
