Python pywin32获取当前所有打开窗口title

import ctypes
 
EnumWindows = ctypes.windll.user32.EnumWindows
EnumWindowsProc = ctypes.WINFUNCTYPE(ctypes.c_bool, ctypes.POINTER(ctypes.c_int), ctypes.POINTER(ctypes.c_int))
GetWindowText = ctypes.windll.user32.GetWindowTextW
GetWindowTextLength = ctypes.windll.user32.GetWindowTextLengthW
IsWindowVisible = ctypes.windll.user32.IsWindowVisible
 
titles = []
def foreach_window(hwnd, lParam):
    if IsWindowVisible(hwnd):
        length = GetWindowTextLength(hwnd)
        buff = ctypes.create_unicode_buffer(length + 1)
        GetWindowText(hwnd, buff, length + 1)
        titles.append(buff.value)
    return True
EnumWindows(EnumWindowsProc(foreach_window), 0)
 
print(titles)

同理访问所有内部窗口

def foreach_window(hwnd, param):
        if IsWindowVisible(hwnd):
                length = GetWindowTextLength(hwnd)
                buff = create_unicode_buffer(length + 1)
                GetWindowText(hwnd, buff, length + 1)
                titles.append(buff.value)
        return True
win32gui.EnumChildWindows(mainwnd, foreach_window, None)
print(titles)
