  CoroutinesIOSystemFacilities | Coroutines, I/O and system facilities.

## Constructor & Destructor Documentation

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

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

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

Destroys the QsciLexerLua instance.

## Member Function Documentation

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

Returns the name of the language.

Implements QsciLexer.

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

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

Implements QsciLexer.

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

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

See also:
  defaultPaper()

Reimplemented from QsciLexer.

bool QsciLexerLua::defaultEolFill | ( | int | style | ) | const`[virtual]`

Returns the end-of-line fill for style number style.

Reimplemented from QsciLexer.

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

Returns the font for style number style.

Reimplemented from QsciLexer.

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

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

See also:
  defaultColor()

Reimplemented from QsciLexer.

const char* QsciLexerLua::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 QsciLexerLua::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 QsciLexerLua::refreshProperties | ( |  | ) | `[virtual]`

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

Reimplemented from QsciLexer.

bool QsciLexerLua::foldCompact | ( |  | ) | const

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

See also:
  setFoldCompact()

virtual void QsciLexerLua::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 QsciLexerLua::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 QsciLexerLua::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.
