Detailed Description

A QSyntaxHighlighter implementation for use with QTextDocument.

This supports partial re-highlighting during editing and tracks syntax-based code folding regions.

Since: 5.28

Member Function Documentation

◆ applyFolding()

void SyntaxHighlighter::applyFolding	(	int	offset,
		int	length,
		FoldingRegion	region )

overrideprotectedvirtual

Reimplement this to apply folding to your output.

The provided FoldingRegion region either stars or ends a code folding region in the interval [offset, offset + length).

Parameters

offset	The start column of the FoldingRegion
length	The length of the matching text that starts / ends a folding region
region	The FoldingRegion that applies to the range [offset, offset + length)

Note: The FoldingRegion region is always either of type FoldingRegion::Type::Begin or FoldingRegion::Type::End.

See also: applyFormat(), highlightLine(), FoldingRegion

Reimplemented from KSyntaxHighlighting::AbstractHighlighter.

Definition at line 249 of file syntaxhighlighter.cpp.

◆ applyFormat()

void SyntaxHighlighter::applyFormat	(	int	offset,
		int	length,
		const Format &	format )

overrideprotectedvirtual

Reimplement this to apply formats to your output.

The provided format is valid for the interval [offset, offset + length).

Parameters

offset	The start column of the interval for which `format` matches
length	The length of the matching text
format	The Format that applies to the range [offset, offset + length)

Note: Make sure to set a valid Definition, otherwise the parameter format is invalid for the entire line passed to highlightLine() (cf. Format::isValid()).

See also: applyFolding(), highlightLine()

Implements KSyntaxHighlighting::AbstractHighlighter.

Definition at line 225 of file syntaxhighlighter.cpp.

◆ findFoldingRegionEnd()

QTextBlock SyntaxHighlighter::findFoldingRegionEnd ( const QTextBlock & startBlock ) const

Finds the end of the folding region starting at startBlock.

If multiple folding regions begin at startBlock, the end of the last/innermost one is returned. This returns an invalid block if no folding region end is found, which typically indicates an unterminated region and thus folding until the document end. This method performs a sequential search starting at startBlock for the matching folding region end, which is a potentially expensive operation.

See also: startsFoldingRegion

Definition at line 158 of file syntaxhighlighter.cpp.

◆ highlightBlock()

void SyntaxHighlighter::highlightBlock ( const QString & text )

overrideprotectedvirtual

Implements QSyntaxHighlighter.

Definition at line 188 of file syntaxhighlighter.cpp.

◆ setDefinition()

void SyntaxHighlighter::setDefinition ( const Definition & def )

overridevirtual

Sets the syntax definition used for highlighting.

Subclasses can re-implement this method to e.g. trigger re-highlighting or clear internal data structures if needed.

Reimplemented from KSyntaxHighlighting::AbstractHighlighter.

Definition at line 130 of file syntaxhighlighter.cpp.

◆ setTheme()

void SyntaxHighlighter::setTheme ( const Theme & theme )

overridevirtual

Sets the theme used for highlighting.

Subclasses can re-implement this method to e.g. trigger re-highlighing or to do general palette color setup.

Reimplemented from KSyntaxHighlighting::AbstractHighlighter.

Definition at line 144 of file syntaxhighlighter.cpp.

◆ startsFoldingRegion()

bool SyntaxHighlighter::startsFoldingRegion ( const QTextBlock & startBlock ) const

Returns whether there is a folding region beginning at startBlock.

This only considers syntax-based folding regions, not indention-based ones as e.g. found in Python.
