Member Function Documentation

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.

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.

Implements VisualDisplay2D::Shape.
