void VisualDisplay2D::Text::draw | ( | Cairo::RefPtr< Cairo::Context > & | cr | ) | [virtual] |
Draw shape to Cairo context.
This method shall be implemented by a shape to draw itself using the provided Cairo context.
cr | reference to Cairo context. Note that this is a reference bypassing the reference pointer. This is done for efficiency and with the assumption that this method is only called by VisualDisplay2D::draw() which itself has proper refptr handling. |
Implements VisualDisplay2D::Shape.
