`findChildren(QFrame)` also find QLabel object

[feiyuhuahuo]

I use findChildren(QFrame) to get all the QFrame objects in a QDialog.

        all_frames = frame.parent().findChildren(QFrame)
        pdb.set_trace()

But all_frames also include QLabel object, why?

[<PySide6.QtWidgets.QFrame(0x234b2bea190, name="frame") at 0x00000234ADEE4CC0>, <PySide6.QtWidgets.QLabel(0x234b2be9b00, name="label_1") at 0x00000234ADEE4E00>, <PySide6.QtWidgets.QFrame(0x234b2bea5e0, name="frame_2") at 0x00000234ADEE4E40>, <PySide6.QtWidgets.QLabel(0x234b2bea5b0, name="label_2") at 0x00000234ADEE4F40>, <PySide6.QtWidgets.QFrame(0x234b2bea520, name="frame_3") at 0x00000234ADEE4FC0>, <PySide6.QtWidgets.QLabel(0x234b2b9b360, name="label_3") at 0x00000234ADEE5140>, <PySide6.QtWidgets.QFrame(0x234b2b9b870, name="frame_4") at 0x00000234ADEE51C0>, <PySide6.QtWidgets.QLabel(0x234b2b9b270, name="label_4") at 0x00000234ADEE5300>, <PySide6.QtWidgets.QLabel(0x234b2b9b180, name="label_task") at 0x00000234ADEE5380>]

Because if you look at QLabel Class you can see it inherits from QFrame.
