python 遍历出 指定标题的 句柄 和其所有 子句柄和孙句柄 并提取出来

可以使用 Python 的 `pyautogui` 库和 `win32gui` 库来实现遍历窗口句柄和提取子句柄和孙句柄。

以下是一个示例代码，它可以遍历 Windows 窗口，找到指定标题的句柄，并提取出它的所有子句柄和孙句柄：

import pyautogui
import win32gui

def get_hwnds_for_pid (pid):
    def callback (hwnd, hwnds):
        if win32gui.IsWindowVisible (hwnd) and win32gui.IsWindowEnabled (hwnd):
            _, found_pid = win32gui.GetWindowThreadProcessId (hwnd)
            if found_pid == pid:
                hwnds.append (hwnd)
        return True
    hwnds = []
    win32gui.EnumWindows (callback, hwnds)
    return hwnds

def get_child_hwnds (hwnd):
    child_hwnds = []
    win32gui.EnumChildWindows (hwnd, lambda hwnd, param: param.append(hwnd), child_hwnds)
    return child_hwnds

def get_descendant_hwnds (hwnd):
    descendant_hwnds = []
    def enum(hwnd, param):
        param.append(hwnd)
        win32gui.EnumChildWindows(hwnd, enum, param)
    enum(hwnd, descendant_hwnds)
    return descendant_hwnds

def find_window(title):
    hwnds = get_hwnds_for_pid (win32gui.GetWindowThreadProcessId (win32gui.GetForegroundWindow ()))
    for hwnd in hwnds:
        if win32gui.GetWindowText(hwnd) == title:
            return hwnd
    return None

def extract_text(hwnd):
    text = win32gui.GetWindowText(hwnd)
    if text:
        return text.strip()
    else:
        return ''

def extract_text_from_hwnds(hwnds):
    texts = []
    for hwnd in hwnds:
        text = extract_text(hwnd)
        if text:
            texts.append(text)
    return texts

# 示例使用方法
window_title = "指定标题"
window_hwnd = find_window(window_title)
if window_hwnd:
    child_hwnds = get_child_hwnds(window_hwnd)
    descendant_hwnds = get_descendant_hwnds(window_hwnd)
    child_texts = extract_text_from_hwnds(child_hwnds)
    descendant_texts = extract_text_from_hwnds(descendant_hwnds)
    print("子句柄文本：", child_texts)
    print("孙句柄文本：", descendant_texts)
else:
    print("未找到窗口：", window_title)

你可以将代码中的 `window_title` 替换为你要查找的窗口标题，然后运行代码即可。
