## Member Enumeration Documentation

anonymous enum

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

Enumerator:

  Default | The default.
  Comment | A comment.
  CommentLine | A comment line.
  Number | A number.
  Operator | An operator.
  Identifier | An identifier.
  String | A string.
  UnclosedString | The end of a line where a string is not closed.
  Directive | A directive.
  BadDirective | A bad directive.
  ObjectsCSGAppearance | Objects, CSG and appearance.
  TypesModifiersItems | Types, modifiers and items.
  PredefinedIdentifiers | Predefined identifiers.
  PredefinedFunctions | Predefined identifiers.
  KeywordSet6 | A keyword defined in keyword set number 6. The class must be sub-classed and re-implement keywords() to make use of this style.
  KeywordSet7 | A keyword defined in keyword set number 7. The class must be sub-classed and re-implement keywords() to make use of this style.
  KeywordSet8 | A keyword defined in keyword set number 8. The class must be sub-classed and re-implement keywords() to make use of this style.

## Constructor & Destructor Documentation

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

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

## Member Function Documentation

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

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

Reimplemented from QsciLexer.

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

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

See also:
  defaultPaper()

Reimplemented from QsciLexer.

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

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

See also:
  defaultColor()

Reimplemented from QsciLexer.

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

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

Reimplemented from QsciLexer.

bool QsciLexerPOV::foldComments | ( |  | ) | const

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

See also:
  setFoldComments()

bool QsciLexerPOV::foldCompact | ( |  | ) | const

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

See also:
  setFoldCompact()

bool QsciLexerPOV::foldDirectives | ( |  | ) | const

Returns true if directives can be folded.

See also:
  setFoldDirectives()

virtual void QsciLexerPOV::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 QsciLexerPOV::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()

virtual void QsciLexerPOV::setFoldDirectives | ( | bool | fold | ) | `[virtual, slot]`

If fold is true then directives can be folded. The default is false.

See also:
  foldDirectives()

bool QsciLexerPOV::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 QsciLexerPOV::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.
