Python活动窗口记录器

Question

如何使用python在活动窗口（例如'example_window_name'）中记录用户输入？我可以使用以下方法获取活动窗口：

from win32gui import GetWindowText, GetForegroundWindow
print GetWindowText(GetForegroundWindow())

但是我将如何枚举窗口，直到'example_window_name'为活动窗口，然后开始记录用户在'example_window_name'中输入的击键，直到它变为非活动状态。 这是我到目前为止所得到的：

import win32gui
import re

class WindowMgr:
"""Encapsulates some calls to the winapi for window management"""
def __init__ (self):
    """Constructor"""
    self._handle = None

def find_window(self, class_name, window_name = None):
    """find a window by its class_name"""
    self._handle = win32gui.FindWindow(class_name, window_name)

def _window_enum_callback(self, hwnd, wildcard):
    '''Pass to win32gui.EnumWindows() to check all the opened windows'''
    if re.match(wildcard, str(win32gui.GetWindowText(hwnd))) != None:
        self._handle = hwnd

def find_window_wildcard(self, wildcard):
    self._handle = None
    win32gui.EnumWindows(self._window_enum_callback, wildcard)

def set_foreground(self):
    """put the window in the foreground"""
    win32gui.SetForegroundWindow(self._handle)

w = WindowMgr()
w.find_window_wildcard(".*Hello.*")
w.set_foreground()

感谢您的帮助！
