Question

假设我有一个窗口，我想模拟鼠标点击在特定的x，y坐标处。我已经有了hwnd，但我不确定如何构造lParam。我过去使用过SendMessage来点击按钮等，但我知道他们的hwnds。任何帮助将不胜感激。我也忍不住想知道我正确地走这条路。我的最终目标是点击某个 skype主窗口上的用户（例如）。我使用了EnumChildWindows 找到所有主窗口的孩子，但找不到合适的孩子。所以我想我会尝试使用坐标“点击”它。

我认为这对你来说很好，你可以直接使用或将它导入你的python程序。

"""mousemacro.py defines the following functions:

click() -- calls left mouse click
hold() -- presses and holds left mouse button
release() -- releases left mouse button

rightclick() -- calls right mouse click
righthold() -- calls right mouse hold
rightrelease() -- calls right mouse release

middleclick() -- calls middle mouse click
middlehold() -- calls middle mouse hold
middlerelease() -- calls middle mouse release

move(x,y) -- moves mouse to x/y coordinates (in pixels)
getpos() -- returns mouse x/y coordinates (in pixels)
slide(x,y) -- slides mouse to x/y coodinates (in pixels)
              also supports optional speed='slow', speed='fast'

Answer 2

由于ctypes，你可以使用低级别的windows api。请参阅下面的示例（根据我未测试的内容改编，但应该没问题）

import ctypes
MOUSEEVENTF_MOVE = 0x0001 # mouse move
MOUSEEVENTF_ABSOLUTE = 0x8000 # absolute move
MOUSEEVENTF_MOVEABS = MOUSEEVENTF_MOVE + MOUSEEVENTF_ABSOLUTE

MOUSEEVENTF_LEFTDOWN = 0x0002 # left button down 
MOUSEEVENTF_LEFTUP = 0x0004 # left button up 
MOUSEEVENTF_CLICK = MOUSEEVENTF_LEFTDOWN + MOUSEEVENTF_LEFTUP

def click(x, y):
    #move first
    x = 65536L * x / ctypes.windll.user32.GetSystemMetrics(0) + 1
    y = 65536L * y / ctypes.windll.user32.GetSystemMetrics(1) + 1
    ctypes.windll.user32.mouse_event(MOUSEEVENTF_MOVEABS, x, y, 0, 0)

    #then click
    ctypes.windll.user32.mouse_event(MOUSEEVENTF_CLICK, 0, 0, 0, 0)

更新：我没有测试下面的代码，但我认为它应该帮助你写一些东西来获得孩子的位置。然后，您可以尝试单击正确的位置。

CHILD= None

def the_callback(child_hwnd, regex):
    '''Pass to win32gui.EnumWindows() to check all the opened windows'''
    if re.match(regex, win32gui.GetWindowText(child_hwnd)):
        CHILD= child_hwnd

win32gui.EnumChildWindows(hwnd, the_callback, regex)


if CHILD:
    (x_tl, y_tl, x_br, y_br) = win32gui.GetWindowRect(CHILD)

python win32模拟点击
