Constructor & Destructor Documentation

QicsDataVariant::QicsDataVariant (  )  [inline]

QicsDataVariant::QicsDataVariant ( const QicsDataVariant ds  ) 

Copy Constructor


Member Function Documentation

QicsDataItem* QicsDataVariant::create ( void   )  const [inline, virtual]

A "virtual constructor". Returns an empty, newly allocated object of the same type as this object.

Implements QicsDataItem.

QicsDataItem* QicsDataVariant::clone ( void   )  const [inline, virtual]

A "virtual copy constructor". Returns a newly allocated copy of this object.

Implements QicsDataItem.

static QString QicsDataVariant::typeName ( void   )  [inline, static]

Returns "qvariant".

Referenced by typeString().

virtual QString QicsDataVariant::typeString ( void   )  const [inline, virtual]

Returns QicsDataVariant::typeName()

Implements QicsDataItem.

References typeName().

virtual QicsDataItemType QicsDataVariant::type ( void   )  const [inline, virtual]

Returns the data type of the item, QicsDataItem_Variant

Implements QicsDataItem.

virtual bool QicsDataVariant::setString ( const QString &  qs  )  [inline, virtual]

Converts (if necessary) qs to the appropriate data type and sets the contents of the data item to that value.

Implements QicsDataItem.

virtual double QicsDataVariant::number ( bool *  ok = 0  )  const [inline, virtual]

Converts (if necessary) the contents of the data item to a double and returns that value. ok flag shows success of the conversion in the case of true.

Since:
2.4

Implements QicsDataItem.

virtual QString QicsDataVariant::format ( const char *   )  const [inline, virtual]

Converts (if necessary) the contents of the data item to a formatted QString using the supplied formatting string, and returns the formatted string. The exact definition of the formatting string varies among data types.

Reimplemented from QicsDataItem.

bool QicsDataVariant::setData ( const QVariant &  v  )  [inline]

Sets the value of this data item to v.

QVariant QicsDataVariant::data ( void   )  const [inline]

Returns a copy of the value of this data item.

virtual const QString QicsDataVariant::string ( void   )  const [inline, virtual]

Converts (if necessary) the contents of the data item to a QString and returns that string.

Implements QicsDataItem.

int QicsDataVariant::compareTo ( const QicsDataItem x  )  const [virtual]

Compare another data item x to me for the purpose of sorting. compareTo returns a value < 0 if this items is less than x, 0 if this item == x, and > 0 if this item is greater than x.

Reimplemented from QicsDataItem.

void QicsDataVariant::encode ( QDataStream &  ds  )  const [inline, virtual]

Encodes the value of the data item onto stream ds.

Implements QicsDataItem.

References QicsDataItem::typeString().

static QicsDataItem* QicsDataVariant::decode ( QDataStream &  ds  )  [static]

Returns a new string data item based on the data encoded in ds.

Reimplemented from QicsDataItem.

static QicsDataItem* QicsDataVariant::fromString ( const QString &  str  )  [static]

Reimplemented from QicsDataItem.

static void QicsDataItem::registerType ( const QString  type_name,
QicsDataItemParser  parser,
QicsDataItemDecoder  decoder 
) [static, inherited]

Used to register a new, user-defined type so that the type can be used in streaming, drag and drop, and cut and paste operations. User-defined data item parsers will be called in the order that their types are registered.

Parameters:
type_name name of the new type
parser static member function of the new type that parses an item from a QString
decoder static member function of the new type that decodes an item from a QDataStream
See also:
registerParser

static void QicsDataItem::registerParser ( QicsDataItemParser  parser  )  [static, inherited]

Used to register a new data item parser algorithm. This parser can be used to reimplement the default parsing "algorithm" of QicsDataItem. If a user defined parser method cannot successfully parse a string, it should return 0. If the user defined parser cannot parse a string, the default QicsDataItem parsing algorithm will be used. The default algorithm first tries any individual user defined type parsers (see registerType()), then attempts to parse the built in types.

Parameters:
parser the new data item parser method

registerType
