//! \brief The QsciStyle class encapsulates all the attributes of a style.
//!
//! Each character of a document has an associated style which determines how
//! the character is displayed, e.g. its font and color.  A style is identified
//! by a number.  Lexers define styles for each of the language's features so
//! that they are displayed differently.  Some style numbers have hard-coded
//! meanings, e.g. the style used for call tips.
