Not full auto completion for WxPython in PyCharm Community Edition

In this example:

frame = wx.Frame(parent=None, title='Hello, World!')

Auto completion work for wx.Frame but don't work in parentheses. So when i'm write par it did't auto-complete for parent=.

I tried google it but didn't find answer.

I'm using PyCharm Community 2019.3 . Miniconda3 with Python 3.7.4 . wxpython 4.0.4

Could you please navigate to Frame definition by Right Click on it - Go To - Declaration or Usages. What parameters does its constructor have?

def __init__(self, *args, **kw):
        """
        Frame()
        Frame(parent, id=ID_ANY, title=EmptyString, pos=DefaultPosition, size=DefaultSize, style=DEFAULT_FRAME_STYLE, name=FrameNameStr)

        A frame is a window whose size and position can (usually) be changed
        by the user.
        """

It shows a \Miniconda3\Lib\site-packages\wx\core.pyi file with Frame class inside.
