[PyQt] PyQt, QSVGWidget background color

[Matt Smith]

Okay, I made a graphing tool.  Works great, somebody suggested that the
background should be white.  No problem...I took the widget,

widget.palette().background().setColor(QColor('white'))

and it turned white.  But that turned the background of every widget in
the main window white too.  Is there a way to seperate this widget's
palette from the main windows palette?

I am thinking of making a large filled square that takes up my whole svg
image if I can't do it through qt.

thanks
