void VisualDisplay2D::Line::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.

Parameters:

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.
