## 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. Note that keywords must be defined using lower case.
  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. Note that keywords must be defined using lower case.
  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. Note that keywords must be defined using lower case.
  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. Note that keywords must be defined using lower case.
  QuotedIdentifier | A quoted identifier.

## Constructor & Destructor Documentation

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

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

## Member Function Documentation

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

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

Reimplemented from 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.

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::backslashEscapes | ( |  | ) | const`[inline]`

Returns true if backslash escapes are enabled.

See also:
  setBackslashEscapes()

void QsciLexerSQL::setDottedWords | ( | bool | enable | ) |

If enable is true then words may contain dots (i.e. periods or full stops). The default is false.

See also:
  dottedWords()

bool QsciLexerSQL::dottedWords | ( |  | ) | const`[inline]`

Returns true if words may contain dots (i.e. periods or full stops).

See also:
  setDottedWords()

void QsciLexerSQL::setFoldAtElse | ( | bool | fold | ) |

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

See also:
  foldAtElse()

bool QsciLexerSQL::foldAtElse | ( |  | ) | const`[inline]`

Returns true if ELSE blocks can be folded.

See also:
  setFoldAtElse()

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

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

See also:
  setFoldComments()

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

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

See also:
  setFoldCompact()

void QsciLexerSQL::setFoldOnlyBegin | ( | bool | fold | ) |

If fold is true then only BEGIN blocks can be folded. The default is false.

See also:
  foldOnlyBegin()

bool QsciLexerSQL::foldOnlyBegin | ( |  | ) | const`[inline]`

Returns true if BEGIN blocks only can be folded.

See also:
  setFoldOnlyBegin()

void QsciLexerSQL::setHashComments | ( | bool | enable | ) |

If enable is true then '#' is used as a comment character. It is typically enabled for MySQL and disabled for Oracle. The default is false.

See also:
  hashComments()

bool QsciLexerSQL::hashComments | ( |  | ) | const`[inline]`

Returns true if '#' is used as a comment character.

See also:
  setHashComments()

void QsciLexerSQL::setQuotedIdentifiers | ( | bool | enable | ) |

If enable is true then quoted identifiers are enabled. The default is false.

See also:
  quotedIdentifiers()

bool QsciLexerSQL::quotedIdentifiers | ( |  | ) | const`[inline]`

Returns true if quoted identifiers are enabled.

See also:
  setQuotedIdentifiers()

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

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

See also:
  backslashEscapes()

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()

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.
