# 或者: from qwt.qt.QtCore.QRectF import moveBottom [as 別名]
#.........這裏部分代碼省略.........
:param QRectF rect: Rectangle for the scaled graphic
:param Qt.AspectRatioMode aspectRatioMode: Mode how to scale
.. py:method:: render(painter, pos, aspectRatioMode)
Replay all recorded painter commands
The graphic is scaled to the :py:meth:`defaultSize()` and aligned
to a position.
:param QPainter painter: Qt painter
:param QPointF pos: Reference point, where to render
:param Qt.AspectRatioMode aspectRatioMode: Mode how to scale
