## Detailed Description

The QsciLexerPython class encapsulates the Scintilla Python lexer.

## Member Enumeration Documentation

anonymous enum

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

Enumerator:

  Default | The default.
  Comment | A comment.
  Number | A number.
  DoubleQuotedString | A double-quoted string.
  SingleQuotedString | A single-quoted string.
  Keyword | A keyword.
  TripleSingleQuotedString | A triple single-quoted string.
  TripleDoubleQuotedString | A triple double-quoted string.
  ClassName | The name of a class.
  FunctionMethodName | The name of a function or method.
  Operator | An operator.
  Identifier | An identifier.
  CommentBlock | A comment block.
  UnclosedString | The end of a line where a string is not closed.
  HighlightedIdentifier | A highlighted identifier. These are defined by keyword set 2. Reimplement keywords() to define keyword set 2.
  Decorator | A decorator.

enum QsciLexerPython::IndentationWarning

This enum defines the different conditions that can cause indentations to be displayed as being bad.

Enumerator:

  NoWarning | Bad indentation is not displayed differently.
  Inconsistent | The indentation is inconsistent when compared to the previous line, ie. it is made up of a different combination of tabs and/or spaces.
  TabsAfterSpaces | The indentation is made up of spaces followed by tabs.
  Spaces | The indentation contains spaces.
  Tabs | The indentation contains tabs.

## Constructor & Destructor Documentation

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

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

## Member Function Documentation

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

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

Reimplemented from QsciLexer.

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

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

See also:
  defaultPaper()

Reimplemented from QsciLexer.

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

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

See also:
  defaultColor()

Reimplemented from QsciLexer.

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

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

Reimplemented from QsciLexer.

bool QsciLexerPython::foldComments | ( |  | ) | const`[inline]`

Returns true if indented comment blocks can be folded.

See also:
  setFoldComments()

void QsciLexerPython::setFoldCompact | ( | bool | fold | ) |

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

See also:
  foldCompact()

bool QsciLexerPython::foldCompact | ( |  | ) | const`[inline]`

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

See also:
  setFoldCompact()

bool QsciLexerPython::foldQuotes | ( |  | ) | const`[inline]`

Returns true if triple quoted strings can be folded.

See also:
  setFoldQuotes()

QsciLexerPython::IndentationWarning QsciLexerPython::indentationWarning | ( |  | ) | const`[inline]`

Returns the condition that will cause bad indentations to be displayed.

See also:
  setIndentationWarning()

void QsciLexerPython::setHighlightSubidentifiers | ( | bool | enabled | ) |

If enabled is true then sub-identifiers defined in keyword set 2 will be highlighted. For example, if it is false and "open" is defined in keyword set 2 then "foo.open" will not be highlighted. The default is true.

See also:
  highlightSubidentifiers()

bool QsciLexerPython::highlightSubidentifiers | ( |  | ) | const`[inline]`

Returns true if string literals are allowed to span newline characters.

See also:
  setHighlightSubidentifiers()

void QsciLexerPython::setStringsOverNewlineAllowed | ( | bool | allowed | ) |

If allowed is true then string literals are allowed to span newline characters. The default is false.

See also:
  stringsOverNewlineAllowed()

bool QsciLexerPython::stringsOverNewlineAllowed | ( |  | ) | const`[inline]`

Returns true if string literals are allowed to span newline characters.

See also:
  setStringsOverNewlineAllowed()

void QsciLexerPython::setV2UnicodeAllowed | ( | bool | allowed | ) |

If allowed is true then Python v2 unicode string literals (e.g. u"utf8") are allowed. The default is true.

See also:
  v2UnicodeAllowed()

bool QsciLexerPython::v2UnicodeAllowed | ( |  | ) | const`[inline]`

Returns true if Python v2 unicode string literals (e.g. u"utf8") are allowed.

See also:
  setV2UnicodeAllowed()

void QsciLexerPython::setV3BinaryOctalAllowed | ( | bool | allowed | ) |

If allowed is true then Python v3 binary and octal literals (e.g. 0b1011, 0o712) are allowed. The default is true.

See also:
  v3BinaryOctalAllowed()

bool QsciLexerPython::v3BinaryOctalAllowed | ( |  | ) | const`[inline]`

Returns true if Python v3 binary and octal literals (e.g. 0b1011, 0o712) are allowed.

See also:
  setV3BinaryOctalAllowed()

void QsciLexerPython::setV3BytesAllowed | ( | bool | allowed | ) |

If allowed is true then Python v3 bytes string literals (e.g. b"bytes") are allowed. The default is true.

See also:
  v3BytesAllowed()

bool QsciLexerPython::v3BytesAllowed | ( |  | ) | const`[inline]`

Returns true if Python v3 bytes string literals (e.g. b"bytes") are allowed.

See also:
  setV3BytesAllowed()

virtual void QsciLexerPython::setFoldComments | ( | bool | fold | ) | `[virtual, slot]`

If fold is true then indented comment blocks can be folded. The default is false.

See also:
  foldComments()

virtual void QsciLexerPython::setFoldQuotes | ( | bool | fold | ) | `[virtual, slot]`

  indentationWarning()

bool QsciLexerPython::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 QsciLexerPython::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.
