查找窗体

移动窗体

查找窗口

# 获取前景窗口句柄
hwnd = win32gui.GetForegroundWindow()

# 设置某个句柄为前景
win32gui.SetForegroundWindow(hwnd)

# 获取前景窗口标题
title = win32gui.GetWindowText(hwnd)

枚举所有窗口

获取键盘布局列表

查找指定窗口

查找指定窗口或子窗口

# 查找指定窗口

获取窗口相关信息

获取窗口class_name、window_text

def get_window_info(hwnd:int) -> dict:
    class_name = win32gui.GetClassName(hwnd)
    window_text = win32gui.GetWindowText(hwnd)
