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!
<http://www.pyside.org/docs/shiboken/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:`~PySide2.QtGui.QWidget`'s :meth:`~PySide2.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()
# ...
