Where is the auto-resize TextView used in the GDK map class?

Thus, the GDK provides a class Cardthat is pretty good for creating maps at runtime. A method setText()for maps is especially useful , which automatically sets the font size that best suits the map, depending on the amount of text and available space.

Is it found somewhere or is there source code to download?
