为了释放这些内存,你可以在 `pysimplegui` 窗口关闭时添加一个回调函数。回调函数可以调用 `decrypt()` 函数并释放其返回的内存。以下是一个示例代码:
```python
import PySimpleGUI as sg
def decrypt():
key = 0xAB
with open('keruan.pth', 'rb') as file:
decrypted_data = bytearray(byte ^ key for byte in file.read())
decrypted_content_memory = io.BytesIO(decrypted_data)
decrypted_content_memory.seek(0)
return decrypted_content_memory
def close_window_callback():
decrypted_content_memory.close()
layout = [[sg.Text('Hello World!')]]
window = sg.Window('My Window', layout, finalize=True)
window.close_callback = close_window_callback
while True:
event, values = window.read()
if event == sg.WINDOW_CLOSED:
break
decrypted_content_memory = decrypt()
# Do something with decrypted_content_memory
window.close()
```
在上述代码中,我们定义了一个 `close_window_callback()` 函数,它会在 `pysimplegui` 窗口关闭时被调用。在主循环中,我们将这个回调函数赋值给 `window.close_callback` 属性。这样,当用户关闭窗口时,`close_window_callback()` 函数就会自动被调用。
在 `close_window_callback()` 函数中,我们调用了 `decrypted_content_memory.close()` 方法来释放内存。要注意的是,如果你在其他地方也使用了 `decrypted_content_memory`,就不能在这里直接将它赋值为 `None`,否则会导致其他部分出错。
