Python gets and sets the current Windows window

In the process of Python screen automation, it is inevitable to involve the operation of the window. Theoretically, you can use mouse and keyboard + screen recognition (complete simulation of people) to achieve this, but it is a bit troublesome to do it in detail. If you don’t consider cross-platform compatibility, then the introduction of Win32GUI library, can save a lot of work.

Get the current window

Import win32gui # access to handle to the window HWND. = win32gui GetForegroundWindow (#) to obtain the window title win32gui. GetWindowText (HWND)

To find the window

Hwnd = Win32Gui.FindWindow(None, title)

Set the current window

The import win32gui # according to the HWND = 5378992 # handle handle should be the other way to get to the win32gui. The SetForegroundWindow (HWND)

Complete sample

import time import win32gui def get_current_window(): return win32gui.GetForegroundWindow() def set_current_window(hwnd): win32gui.SetForegroundWindow(hwnd) def get_window_title(hwnd): return win32gui.GetWindowText(hwnd) def get_current_window_title(): return get_window_title(get_current_window()) def find_window_by_title(title): try: return win32gui.FindWindow(None, title) except Exception as ex: print('error calling win32gui.FindWindow ' + str(ex)) return -1 if __name__ == "__main__": Print (get_current_window()) print(get_current_window_title()) print(get_current_window_title()) print(get_current_window_title()) HWND = find_window_by_title(' document ') set_current_window(HWND) time.sleep(1) # Print the title of the window that has just been switched to the front print(get_current_window_title())
