TQScintilla: TQextScintillaLexer Class Reference

+A Scintilla lexer scans the text breaking it up into separate language objects, e.g. keywords, strings, operators. The lexer then uses a different style to draw each object. A style is identified by a style number and has a number of attributes, including colour and font. A specific language lexer will implement appropriate default styles which can be overriden by an application by further sub-classing the specific language lexer.

+A specific language lexer may provide one or more sets of words to be recognised as keywords. Most lexers only provide one set, but some may support languages embedded in other languages and provide several sets.

+TQextScintillaLexer provides convenience methods for saving and restoring user preferences for fonts and colours. +
