  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.

## Constructor & Destructor Documentation

QextScintillaLexerSQL::QextScintillaLexerSQL | ( | QObject * | parent = `0`,
|  | const char * | name = `0` |
| ) |  |  |

Construct a QextScintillaLexerSQL with parent parent and name name. parent is typically the QextScintilla instance.

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

Destroys the QextScintillaLexerSQL instance.

## Member Function Documentation

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

Returns the name of the language.

Implements QextScintillaLexer.

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

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

Implements QextScintillaLexer.

QColor QextScintillaLexerSQL::color | ( | int | style | ) | const`[virtual]`

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

See also:
  paper()

Reimplemented from QextScintillaLexer.

bool QextScintillaLexerSQL::eolFill | ( | int | style | ) | const`[virtual]`

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

Reimplemented from QextScintillaLexer.

QFont QextScintillaLexerSQL::font | ( | int | style | ) | const`[virtual]`

Returns the font for style number style.

Reimplemented from QextScintillaLexer.

const char* QextScintillaLexerSQL::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 QextScintillaLexer.

QString QextScintillaLexerSQL::description | ( | int | style | ) | const`[virtual]`

Returns the descriptive name for style number style. If the style is invalid for this language then QString::null is returned. This is intended to be used in user preference dialogs.

Implements QextScintillaLexer.

QColor QextScintillaLexerSQL::paper | ( | int | style | ) | const`[virtual]`

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

See also:
  color()

Reimplemented from QextScintillaLexer.

void QextScintillaLexerSQL::refreshProperties | ( |  | ) | `[virtual]`

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

Reimplemented from QextScintillaLexer.

bool QextScintillaLexerSQL::foldComments | ( |  | ) | const

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

See also:
  setFoldComments()

bool QextScintillaLexerSQL::foldCompact | ( |  | ) | const

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

See also:
  setFoldCompact()

bool QextScintillaLexerSQL::backslashEscapes | ( |  | ) | const

Returns TRUE if backslash escapes are enabled.

See also:
  setBackslashEscapes()

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

If enable is TRUE then backslash escapes are enabled. The default is FALSE.

See also:
  backslashEscapes()

bool QextScintillaLexerSQL::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 QextScintillaLexer.

bool QextScintillaLexerSQL::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.
