## Constructor & Destructor Documentation

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

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

## Member Function Documentation

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

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

Reimplemented from QsciLexer.

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

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

See also:
  defaultPaper()

Reimplemented from QsciLexer.

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

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

See also:
  defaultColor()

Reimplemented from QsciLexer.

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

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

Reimplemented from QsciLexer.

bool QsciLexerPerl::foldComments | ( |  | ) | const

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

See also:
  setFoldComments()

bool QsciLexerPerl::foldCompact | ( |  | ) | const

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

See also:
  setFoldCompact()

void QsciLexerPerl::setFoldPackages | ( | bool | fold | ) |

If fold is true then packages can be folded. The default is true.

See also:
  foldPackages()

bool QsciLexerPerl::foldPackages | ( |  | ) | const

Returns true if packages can be folded.

See also:
  setFoldPackages()

void QsciLexerPerl::setFoldPODBlocks | ( | bool | fold | ) |

If fold is true then POD blocks can be folded. The default is true.

See also:
  foldPODBlocks()

bool QsciLexerPerl::foldPODBlocks | ( |  | ) | const

Returns true if POD blocks can be folded.

See also:
  setFoldPODBlocks()

virtual void QsciLexerPerl::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 QsciLexerPerl::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 QsciLexerPerl::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 QsciLexerPerl::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.
