    Description

      The following code example shows that the return type of QLayout.itemAtPostion must be `QLayoutItem | None`:

       

      from typing import TYPE_CHECKING
from PySide6.QtWidgets import QGridLayout
layout = QGridLayout()
item = layout.itemAtPosition(0, 0)
print(f"Got {item}")
if TYPE_CHECKING:
    reveal_type(item)

      When I run the code:

      Got None

      When I run mypy:

      note: Revealed type is "PySide6.QtWidgets.QLayoutItem“
