如何在python中使用Ctypes最小化窗口

Question

例如，我们可以这样做

elif查询中的“最大化”：

 speak('Ok sir!')

 user32 = ctypes.WinDLL('user32')

 SW_MAXIMISE = 3

 hWnd = user32.GetForegroundWindow()

 user32.ShowWindow(hWnd, SW_MAXIMISE)

 speak('done sir!')

Answer 1

确保设置.argtypes和.restypeHWND定义为指针，如果不指定，64位系统将不会正确地传递或返回参数，因为ctypes假定int（32位）

import ctypes
from ctypes import wintypes as w

user32 = ctypes.WinDLL('user32')
user32.GetForegroundWindow.argtypes = ()
user32.GetForegroundWindow.restype = w.HWND
user32.ShowWindow.argtypes = w.HWND,w.BOOL
user32.ShowWindow.restype = w.BOOL

# From https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-showwindow
SW_MAXIMIZE = 3
SW_MINIMIZE = 6

hWnd = user32.GetForegroundWindow()
user32.ShowWindow(hWnd, SW_MINIMIZE)
