## 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.

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

Destroys the QsciLexerPython instance.

## Member Function Documentation

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

Returns the name of the language.

Implements QsciLexer.

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

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

Implements 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.

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

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

Reimplemented from QsciLexer.

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

Returns the font for style number style.

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

Returns true if indented comment blocks can be folded.

See also:
  setFoldComments()

bool QsciLexerPython::foldQuotes | ( |  | ) | const

Returns true if triple quoted strings can be folded.

See also:
  setFoldQuotes()

QsciLexerPython::IndentationWarning QsciLexerPython::indentationWarning | ( |  | ) | const

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

See also:
  setIndentationWarning()

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]`

If fold is true then triple quoted strings can be folded. The default is false.

See also:
  foldQuotes()

virtual void QsciLexerPython::setIndentationWarning | ( | QsciLexerPython::IndentationWarning | warn | ) | `[virtual, slot]`

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

See also:
  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.

Reimplemented from QsciLexer.
