python win32模拟点击

Question

假设我有一个窗口，我想要在特定的x，y坐标上模拟鼠标点击 。我已经有了hwnd，但我不确定 如何构建lParam。我以前使用过SendMessage在按钮等上点击 ，但我知道他们的情况。 任何帮助将不胜感激。我也忍不住想知道我是否正确地做这件事。我的最终目标是在Skype主窗口（例如）上点击某个 用户。我用EnumChildWindows 查找所有主窗口的子项，但找不到正确的窗口。所以 想通了，我会尝试使用坐标'点击'它。

感谢ctypes，您可以使用低级别的Windows API。请参见下面的例子（改编自东西我没有测试它，但它应该没问题）

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的东西得到孩子的位置。然后你可以尝试点击正确的位置。

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)

我觉得这对你很好，你可以直接使用或者将它导入到你的python程序中。

"""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'
