In places where you can only use pixmaps, you will need to render the SVG to
an image first. There are places where you can load an SVG and not worry
about that - when you use QIcon for icons, for example.

One nice way of doing this is to use QIcon, though QSvgRenderer might be
better in certain situations. Creating a pixmap from an icon that contains
an SVG drawing is quite simple:

  icon = QIcon(path_to_svg_file)
  pixmap = icon.pixmap(width, height)

The good thing about this is that you only need to load the SVG drawing once.

Of course, if you just want to display an SVG drawing, you can use QSvgWidget
