## Detailed Description

The QsciLexerCPP class encapsulates the Scintilla C++ lexer.

## Member Enumeration Documentation

anonymous enum

This enum defines the meanings of the different styles used by the C++ lexer.

Enumerator:

  Default | The default.
  Comment | A C comment.
  CommentLine | A C++ comment line.
  CommentDoc | A JavaDoc/Doxygen style C comment.
  Number | A number.
  Keyword | A keyword.
  DoubleQuotedString | A double-quoted string.
  SingleQuotedString | A single-quoted string.
  UUID | An IDL UUID.
  PreProcessor | A pre-processor block.
  Operator | An operator.
  Identifier | An identifier.
  UnclosedString | The end of a line where a string is not closed.
  VerbatimString | A C# verbatim string.
  Regex | A JavaScript regular expression.
  CommentLineDoc | A JavaDoc/Doxygen style C++ comment line.
  KeywordSet2 | A keyword defined in keyword set number 2. The class must be sub-classed and re-implement keywords() to make use of this style.
  CommentDocKeyword | A JavaDoc/Doxygen keyword.
  CommentDocKeywordError | A JavaDoc/Doxygen keyword error.
  GlobalClass | A global class or typedef defined in keyword set number 5. The class must be sub-classed and re-implement keywords() to make use of this style.
  RawString | A C++ raw string.
  TripleQuotedVerbatimString | A Vala triple-quoted verbatim string.
  HashQuotedString | A Pike hash-quoted string.
  PreProcessorComment | A pre-processor stream comment.
  PreProcessorCommentLineDoc | A JavaDoc/Doxygen style pre-processor comment.

## Constructor & Destructor Documentation

QsciLexerCPP::QsciLexerCPP | ( | QObject * | parent = `0`,
|  | bool | caseInsensitiveKeywords = `false`
| ) |  |

Construct a QsciLexerCPP with parent parent. parent is typically the QsciScintilla instance. caseInsensitiveKeywords is true if the lexer ignores the case of keywords.

## Member Function Documentation

const char* QsciLexerCPP::lexer | ( |  | ) | const`[virtual]`

Returns the name of the lexer. Some lexers support a number of languages.

Reimplemented from QsciLexer.

QColor QsciLexerCPP::defaultColor | ( | int | style | ) | const`[virtual]`

Returns the foreground colour of the text for style number style.

See also:
  defaultPaper()

Reimplemented from QsciLexer.

Reimplemented in QsciLexerCSharp, QsciLexerJavaScript, and QsciLexerIDL.

QColor QsciLexerCPP::defaultPaper | ( | int | style | ) | const`[virtual]`

Returns the background colour of the text for style number style.

See also:
  defaultColor()

Reimplemented from QsciLexer.

Reimplemented in QsciLexerCSharp, and QsciLexerJavaScript.

const char* QsciLexerCPP::keywords | ( | int | set | ) | const`[virtual]`

Returns the set of keywords for the keyword set set recognised by the lexer as a space separated string. Set 1 is normally used for primary keywords and identifiers. Set 2 is normally used for secondary keywords and identifiers. Set 3 is normally used for documentation comment keywords. Set 4 is normally used for global classes and typedefs.

Reimplemented from QsciLexer.

Reimplemented in QsciLexerCSharp, QsciLexerJavaScript, QsciLexerIDL, and QsciLexerJava.

QString QsciLexerCPP::description | ( | int | style | ) | const`[virtual]`

Returns the descriptive name for style number style. If the style is invalid for this language then an empty QString is returned. This is intended to be used in user preference dialogs.

Implements QsciLexer.

Reimplemented in QsciLexerCSharp, QsciLexerJavaScript, and QsciLexerIDL.

void QsciLexerCPP::refreshProperties | ( |  | ) | `[virtual]`

Causes all properties to be refreshed by emitting the propertyChanged() signal as required.

Reimplemented from QsciLexer.

bool QsciLexerCPP::foldAtElse | ( |  | ) | const`[inline]`

Returns true if "} else {" lines can be folded.

See also:
  setFoldAtElse()

bool QsciLexerCPP::foldComments | ( |  | ) | const`[inline]`

Returns true if multi-line comment blocks can be folded.

See also:
  setFoldComments()

bool QsciLexerCPP::foldCompact | ( |  | ) | const`[inline]`

Returns true if trailing blank lines are included in a fold block.

See also:
  setFoldCompact()

Returns true if preprocessor blocks can be folded.

See also:
  setFoldPreprocessor()

Returns true if preprocessor lines (after the preprocessor directive) are styled.

See also:
  setStylePreprocessor()

void QsciLexerCPP::setDollarsAllowed | ( | bool | allowed | ) |

If allowed is true then '$' characters are allowed in identifier names. The default is true.

See also:
  dollarsAllowed()

bool QsciLexerCPP::dollarsAllowed | ( |  | ) | const`[inline]`

Returns true if '$' characters are allowed in identifier names.

See also:
  setDollarsAllowed()

void QsciLexerCPP::setHighlightTripleQuotedStrings | ( | bool | enabled | ) |

If enabled is true then triple quoted strings are highlighted. The default is false.

See also:
  highlightTripleQuotedStrings()

bool QsciLexerCPP::highlightTripleQuotedStrings | ( |  | ) | const`[inline]`

Returns true if triple quoted strings should be highlighted.

See also:
  setHighlightTripleQuotedStrings()

void QsciLexerCPP::setHighlightHashQuotedStrings | ( | bool | enabled | ) |

If enabled is true then hash quoted strings are highlighted. The default is false.

  highlightHashQuotedStrings()

bool QsciLexerCPP::highlightHashQuotedStrings | ( |  | ) | const`[inline]`

Returns true if hash quoted strings should be highlighted.

See also:
  setHighlightHashQuotedStrings()

virtual void QsciLexerCPP::setFoldAtElse | ( | bool | fold | ) | `[virtual, slot]`

If fold is true then "} else {" lines can be folded. The default is false.

See also:
  foldPreprocessor()

virtual void QsciLexerCPP::setStylePreprocessor | ( | bool | style | ) | `[virtual, slot]`

bool QsciLexerCPP::readProperties | ( | QSettings & | qs,
|  | const QString & | prefix
| ) |  | `[protected, virtual]`

The lexer's properties are read from the settings qs. prefix (which has a trailing '/') should be used as a prefix to the key of each setting. true is returned if there is no error.
