Detailed Description

The QsciLexerCustom class is an abstract class used as a base for new language lexers.

The advantage of implementing a new lexer this way (as opposed to adding the lexer to the underlying Scintilla code) is that it does not require the QScintilla library to be re-compiled. It also makes it possible to integrate external lexers.

All that is necessary to implement a new lexer is to define appropriate styles and to re-implement the styleText() method.

Constructor & Destructor Documentation

QsciLexerCustom::QsciLexerCustom ( QObject * parent = 0 )

Construct a QsciLexerCustom with parent parent. parent is typically the QsciScintilla instance.

Member Function Documentation

void QsciLexerCustom::setStyling	(	int	length,
		int	style
	)

The next length characters starting from the current styling position have their style set to style number style. The current styling position is moved. The styling position is initially set by calling startStyling().

See also: startStyling(), styleText()

void QsciLexerCustom::setStyling	(	int	length,
		const QsciStyle &	style
	)

The next length characters starting from the current styling position have their style set to style style. The current styling position is moved. The styling position is initially set by calling startStyling().

See also: startStyling(), styleText()

void QsciLexerCustom::startStyling	(	int	pos,
		int	styleBits = `0`
	)

The styling position is set to start. styleBits is unused.

See also: setStyling(), styleBitsNeeded(), styleText()

virtual void QsciLexerCustom::styleText	(	int	start,
		int	end
	)

pure virtual

This is called when the section of text beginning at position start and up to position end needs to be styled. start will always be at the start of a line. The text is styled by calling startStyling() followed by one or more calls to setStyling(). It must be re-implemented by a sub-class.

See also: setStyling(), startStyling(), QsciScintilla::bytes(), QsciScintilla::text()

virtual int QsciLexerCustom::styleBitsNeeded ( ) const

virtual

This re-implementation returns 5 as the number of style bits needed.

Reimplemented from QsciLexer.
