我在命令提示符下输入了QOpenGLWindow。但是QOpenGLWindow无法导入。 QOpenGLWindow在哪里?
>>> from PyQt5.QtCore import QT_VERSION_STR
>>> QT_VERSION_STR
'5.2.1'
>>>
>>> from PyQt5.QtGui import QOpenGLWindow
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name 'QOpenGLWindow'
>>>
