## 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 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

bool QsciLexerPython::readProperties | ( | QSettings & | qs,
|  | const QString & | prefix
| ) |  |
| protectedvirtual

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
| protectedvirtual

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.
