在指定位置点击而不移动鼠标的错误

Question

我一直在寻找多种方法来实现“点击”，而不实际移动鼠标。经过几个小时的搜索，我找到了这两个页面：ctypes mouse_events 和 https://schurpf.com/python-mouse-control/，上面有一些代码，似乎可以在不移动鼠标的情况下进行点击。

这些代码看起来是同一个人写的，但 https://schurpf.com/python-mouse-control/ 的内容似乎更新得更及时，增加了一些新功能。

我尝试修复了一段时间，但没有进展，现在卡在了以下脚本上：

import win32gui, win32api, win32con, ctypes

class Mouse:
    """It simulates the mouse"""
    MOUSEEVENTF_MOVE = 0x0001 # mouse move
    MOUSEEVENTF_LEFTDOWN = 0x0002 # left button down
    MOUSEEVENTF_LEFTUP = 0x0004 # left button up
    MOUSEEVENTF_RIGHTDOWN = 0x0008 # right button down
    MOUSEEVENTF_RIGHTUP = 0x0010 # right button up
    MOUSEEVENTF_MIDDLEDOWN = 0x0020 # middle button down
    MOUSEEVENTF_MIDDLEUP = 0x0040 # middle button up
    MOUSEEVENTF_WHEEL = 0x0800 # wheel button rolled
    MOUSEEVENTF_ABSOLUTE = 0x8000 # absolute move
    SM_CXSCREEN = 0
    SM_CYSCREEN = 1

    def _do_event(self, flags, x_pos, y_pos, data, extra_info):
        """generate a mouse event"""
        x_calc = 65536 * x_pos / ctypes.windll.user32.GetSystemMetrics(self.SM_CXSCREEN) + 1
        y_calc = 65536 * y_pos / ctypes.windll.user32.GetSystemMetrics(self.SM_CYSCREEN) + 1
        return ctypes.windll.user32.mouse_event(flags, x_calc, y_calc, data, extra_info)

    def _get_button_value(self, button_name, button_up=False):
        """convert the name of the button into the corresponding value"""
        buttons = 0
        if button_name.find("right") >= 0:
            buttons = self.MOUSEEVENTF_RIGHTDOWN
        if button_name.find("left") >= 0:
            buttons = buttons + self.MOUSEEVENTF_LEFTDOWN
        if button_name.find("middle") >= 0:
            buttons = buttons + self.MOUSEEVENTF_MIDDLEDOWN
        if button_up:
            buttons = buttons << 1
        return buttons

    def move_mouse(self, pos):
        """move the mouse to the specified coordinates"""
        (x, y) = pos
        old_pos = self.get_position()
        x =  x if (x != -1) else old_pos[0]
        y =  y if (y != -1) else old_pos[1]
        self._do_event(self.MOUSEEVENTF_MOVE + self.MOUSEEVENTF_ABSOLUTE, x, y, 0, 0)

    def press_button(self, pos=(-1, -1), button_name="left", button_up=False):
        """push a button of the mouse"""
        self.move_mouse(pos)
        self._do_event(self.get_button_value(button_name, button_up), 0, 0, 0, 0)

    def click(self, pos=(-1, -1), button_name= "left"):
        """Click at the specified placed"""
##        self.move_mouse(pos)
        self._do_event(self._get_button_value(button_name, False)+self._get_button_value(button_name, True), 0, 0, 0, 0)

    def double_click (self, pos=(-1, -1), button_name="left"):
        """Double click at the specifed placed"""
        for i in xrange(2):
            self.click(pos, button_name)

    def get_position(self):
        """get mouse position"""
        return win32api.GetCursorPos()
#-----------------------------------------------------------------------------------------
#Added functions
#-----------------------------------------------------------------------------------------
    def invisible_click(self,pos=(-1, -1), button_name="left"):
        """Click in specified place without moving mouse"""
        xcur,ycur = win32gui.GetCursorPos()
        ctypes.windll.user32.SetCursorPos(pos[0],pos[1])
        self.click(pos,button_name)
        ctypes.windll.user32.SetCursorPos(xcur,ycur)

    def invisible_click_rel(self,handle,pos, button_name="left"):
        """Click in window coordinates without moving mouse"""
        #get window info
        xleft, ytop, xright, ybottom = win32gui.GetWindowRect(handle)

        xcur,ycur = win32gui.GetCursorPos()

        ctypes.windll.user32.SetCursorPos(pos[0]+xleft,pos[1]+ytop)
        self.click((pos[0]+xleft,pos[1]+ytop),button_name)
        ctypes.windll.user32.SetCursorPos(xcur,ycur)

if __name__ == '__main__':
    p = (500,500)
    print (win32gui.GetForegroundWindow())
    mouse = Mouse()
    mouse.invisible_click(p)

我想做的是触发Mouse类的invisible_click函数，让它在位置500,500执行一个“隐形点击”。

我在上面的代码中遇到的错误是：

File "C:\Users\MyName\Desktop\test1del\Future.py", line 21, in _do_event
    return ctypes.windll.user32.mouse_event(flags, x_calc, y_calc, data, extra_info)
ctypes.ArgumentError: argument 2: <class 'TypeError'>: Don't know how to convert parameter 2

抱歉，如果我遗漏了什么明显的地方，我会非常感激你的帮助！感谢你的阅读。
