TQAGetFloat

A drawing engine must define a method to get a floating-point value of a draw context state variable.

typedef float (*TQAGetFloat) (
                              const TQADrawContext *drawContext, 
                              TQATagFloat tag); 

drawContext

A draw context.

tag

A state variable tag.

DESCRIPTION

Your TQAGetFloat function should return, as its function result, the floating-point value of the draw context state variable specified by the drawContext and tag parameters. If you do not recognize or support the specified tag, your TQAGetFloat function should return the value 0.
