## Constructor & Destructor Documentation

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

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

virtual QsciLexerCSS::~QsciLexerCSS | ( |  | ) | `[virtual]`

Destroys the QsciLexerCSS instance.

## Member Function Documentation

const char* QsciLexerCSS::language | ( |  | ) | const`[virtual]`

Returns the name of the language.

Implements QsciLexer.

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

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

Implements QsciLexer.

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

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

Reimplemented from QsciLexer.

QFont QsciLexerCSS::defaultFont | ( | int | style | ) | const`[virtual]`

Returns the font for style number style.

Reimplemented from QsciLexer.

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.

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.

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

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

Reimplemented from QsciLexer.

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

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

See also:
  setFoldComments()

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

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

See also:
  setFoldCompact()

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()

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()

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.

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.

Reimplemented from QsciLexer.
