inline |
Set the default painter to use when not drawing to FBO.
This is the only place where we might be getting a painter from outside world, so we require that it uses a GL or GL2 paint engine.
painter | Painter to set. |
context | GL context used by the renderer, for error checking. |

Set font to use for drawing text.
Can be only called when Qt painting is enabled.
