         Registers a Python created custom widget to QUiLoader, so it can be recognized when
         loading a `.ui` file. The custom widget type is passed via the ``customWidgetType`` argument.
         This is needed when you want to override a virtual method of some widget in the interface,
         since duck punching will not work with widgets created by QUiLoader based on the contents
         of the `.ui` file.

         (Remember that `duck punching virtual methods is an invitation for your own demise!
         &lt;https://doc.qt.io/qtforpython/shiboken6/wordsofadvice.html#duck-punching-and-virtual-methods>`_)

         Let's see an obvious example. If you want to create a new widget it's probable you'll end up
         overriding :class:`~PySide6.QtGui.QWidget`'s :meth:`~PySide6.QtGui.QWidget.paintEvent` method.

         .. code-block:: python

            class Circle(QWidget):
                def paintEvent(self, event):
                    painter = QPainter(self)
                    painter.setPen(self.pen)
                    painter.setBrush(QBrush(self.color))
                    painter.drawEllipse(event.rect().center(), 20, 20)

            # ...

            loader = QUiLoader()
            loader.registerCustomWidget(Circle)
            circle = loader.load('circle.ui')
            circle.show()
