## Member Enumeration Documentation

anonymous enum

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

Enumerator:

  Default | The default.
  Comment | A comment.
  CommentLine | A line comment.
  CommentDoc | A JavaDoc/Doxygen style comment.
  Number | A number.
  Keyword | A keyword.
  DoubleQuotedString | A double-quoted string.
  SingleQuotedString | A single-quoted string.
  PlusKeyword | An SQL*Plus keyword.
  PlusPrompt | An SQL*Plus prompt.
  Operator | An operator.
  Identifier | An identifier.
  PlusComment | An SQL*Plus comment.
  CommentLineHash | A '#' line comment.
  CommentDocKeyword | A JavaDoc/Doxygen keyword.
  CommentDocKeywordError | A JavaDoc/Doxygen keyword error.
  KeywordSet5 | A keyword defined in keyword set number 5. The class must be sub-classed and re-implement keywords() to make use of this style.
  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

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

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

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

Destroys the QsciLexerSQL instance.

## Member Function Documentation

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

Returns the name of the language.

Implements QsciLexer.

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

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

Implements QsciLexer.

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

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

See also:
  defaultPaper()

Reimplemented from QsciLexer.

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

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

Reimplemented from QsciLexer.

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

Returns the font for style number style.

Reimplemented from QsciLexer.

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

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

See also:
  defaultColor()

Reimplemented from QsciLexer.

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

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

Reimplemented from QsciLexer.

bool QsciLexerSQL::foldComments | ( |  | ) | const

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

See also:
  setFoldComments()

bool QsciLexerSQL::foldCompact | ( |  | ) | const

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

See also:
  setFoldCompact()

bool QsciLexerSQL::backslashEscapes | ( |  | ) | const

Returns true if backslash escapes are enabled.

See also:
  setBackslashEscapes()

virtual void QsciLexerSQL::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 QsciLexerSQL::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 QsciLexerSQL::setBackslashEscapes | ( | bool | enable | ) | `[virtual, slot]`

If enable is true then backslash escapes are enabled. The default is false.

See also:
  backslashEscapes()

bool QsciLexerSQL::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 QsciLexerSQL::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.
