## Constructor & Destructor Documentation

## QsciLexerCSS()

QsciLexerCSS::QsciLexerCSS | ( | QObject * | parent = 0 | ) |

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

Referenced by writeProperties().

## Member Function Documentation

## language()

const char * QsciLexerCSS::language | ( |  | ) | const

virtual

Returns the name of the language.

Implements QsciLexer.

## lexer()

const char * QsciLexerCSS::lexer | ( |  | ) | const

virtual

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

Reimplemented from QsciLexer.

## blockEnd()

const char * QsciLexerCSS::blockEnd | ( | int * | style = 0 | ) | const

virtual

Returns a space separated list of words or characters in a particular style that define the end of a block for auto-indentation. The style is returned via style.

Reimplemented from QsciLexer.

## blockStart()

const char * QsciLexerCSS::blockStart | ( | int * | style = 0 | ) | const

virtual

Returns a space separated list of words or characters in a particular style that define the start of a block for auto-indentation. The style is returned via style.

Reimplemented from QsciLexer.

## wordCharacters()

const char * QsciLexerCSS::wordCharacters | ( |  | ) | const

virtual

Returns the string of characters that comprise a word.

Reimplemented from QsciLexer.

## defaultColor()

QColor QsciLexerCSS::defaultColor | ( | int | style | ) | const

virtual

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

Reimplemented from QsciLexer.

## defaultFont()

QFont QsciLexerCSS::defaultFont | ( | int | style | ) | const

virtual

Returns the font for style number style.

Reimplemented from QsciLexer.

## keywords()

const char * QsciLexerCSS::keywords | ( | int | set | ) | const

virtual

Returns the set of keywords for the keyword set set recognised by the lexer as a space separated string.

Reimplemented from QsciLexer.

## description()

QString QsciLexerCSS::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.

## refreshProperties()

void QsciLexerCSS::refreshProperties | ( |  | ) |

virtual

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

Reimplemented from QsciLexer.

## foldComments()

bool QsciLexerCSS::foldComments | ( |  | ) | const

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

See also
  setFoldComments()

## foldCompact()

bool QsciLexerCSS::foldCompact | ( |  | ) | const

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

See also
  setFoldCompact()

## setHSSLanguage()

void QsciLexerCSS::setHSSLanguage | ( | bool | enabled | ) |

If enabled is true then support for HSS is enabled. The default is false.

See also
  HSSLanguage()

## HSSLanguage()

bool QsciLexerCSS::HSSLanguage | ( |  | ) | const

inline

Returns true if support for HSS is enabled.

See also
  setHSSLanguage()

## setLessLanguage()

void QsciLexerCSS::setLessLanguage | ( | bool | enabled | ) |

If enabled is true then support for Less CSS is enabled. The default is false.

See also
  LessLanguage()

## LessLanguage()

bool QsciLexerCSS::LessLanguage | ( |  | ) | const

inline

Returns true if support for Less CSS is enabled.

See also
  setLessLanguage()

## setSCSSLanguage()

void QsciLexerCSS::setSCSSLanguage | ( | bool | enabled | ) |

If enabled is true then support for Sassy CSS is enabled. The default is false.

See also
  SCSSLanguage()

## SCSSLanguage()

bool QsciLexerCSS::SCSSLanguage | ( |  | ) | const

inline

Returns true if support for Sassy CSS is enabled.

See also
  setSCSSLanguage()

## setFoldComments

virtual void QsciLexerCSS::setFoldComments | ( | bool | fold | ) |

virtual slot

If fold is true then multi-line comment blocks can be folded. The default is false.

See also
  foldComments()

## setFoldCompact

virtual void QsciLexerCSS::setFoldCompact | ( | bool | fold | ) |

virtual slot

If fold is true then trailing blank lines are included in a fold block. The default is true.

See also
  foldCompact()

## readProperties()

bool QsciLexerCSS::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.

Reimplemented from QsciLexer.

## writeProperties()

bool QsciLexerCSS::writeProperties | ( | QSettings & | qs,
|  | const QString & | prefix ) const

protected virtual

The lexer's properties are written to 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.
