Without TQVariant, this would be - a problem for TQObject::property() and for database work, etc. - - A TQVariant object holds a single value of a single type() at a - time. (Some type()s are multi-valued, for example a string list.) - You can find out what type, T, the variant holds, convert it to a - different type using one of the asT() functions, e.g. asSize(), - get its value using one of the toT() functions, e.g. toSize(), and - check whether the type can be converted to a particular type using - canCast(). - - The methods named toT() (for any supported T, see the \c Type - documentation for a list) are const. If you ask for the stored - type, they return a copy of the stored object. If you ask for a - type that can be generated from the stored type, toT() copies and - converts and leaves the object itself unchanged. If you ask for a - type that cannot be generated from the stored type, the result - depends on the type (see the function documentation for details). - - Note that three data types supported by TQVariant are explicitly - shared, namely TQImage, TQPointArray, and TQCString, and in these - cases the toT() methods return a shallow copy. In almost all cases - you must make a deep copy of the returned values before modifying - them. - - The asT() functions are not const. They do conversion like the - toT() methods, set the variant to hold the converted value, and - return a reference to the new contents of the variant. - - Here is some example code to demonstrate the use of TQVariant: - - \code - TQDataStream out(...); - TQVariant v(123); // The variant now contains an int - int x = v.toInt(); // x = 123 - out << v; // Writes a type tag and an int to out - v = TQVariant("hello"); // The variant now contains a TQCString - v = TQVariant(tr("hello"));// The variant now contains a TQString - int y = v.toInt(); // y = 0 since v cannot be converted to an int - TQString s = v.toString(); // s = tr("hello") (see TQObject::tr()) - out << v; // Writes a type tag and a TQString to out - ... - TQDataStream in(...); // (opening the previously written stream) - in >> v; // Reads an Int variant - int z = v.toInt(); // z = 123 - qDebug("Type is %s", // prints "Type is int" - v.typeName()); - v.asInt() += 100; // The variant now hold the value 223. - v = TQVariant( TQStringList() ); - v.asStringList().append( "Hello" ); - \endcode - - You can even store TQValueList<TQVariant>s and - TQMap<TQString,TQVariant>s in a variant, so you can easily construct - arbitrarily complex data structures of arbitrary types. This is - very powerful and versatile, but may prove less memory and speed - efficient than storing specific types in standard data structures. - - TQVariant also supports the notion of NULL values, where you have a - defined type with no value set. - \code - TQVariant x, y( TQString() ), z( TQString("") ); - x.asInt(); - // x.isNull() == TRUE, y.isNull() == TRUE, z.isNull() == FALSE - \endcode - - See the \link collection.html Collection Classes\endlink. -*/ - -/*! - \enum TQVariant::Type - - This enum type defines the types of variable that a TQVariant can - contain. - - \value Invalid no type - \value BitArray a TQBitArray - \value ByteArray a TQByteArray - \value Bitmap a TQBitmap - \value Bool a bool - \value Brush a TQBrush - \value Color a TQColor - \value ColorGroup a TQColorGroup - \value Cursor a TQCursor - \value Date a TQDate - \value DateTime a TQDateTime - \value Double a double - \value Font a TQFont - \value IconSet a TQIconSet - \value Image a TQImage - \value Int an int - \value KeySequence a TQKeySequence - \value List a TQValueList<TQVariant> - \value LongLong a long long - \value ULongLong an unsigned long long - \value Map a TQMap<TQString,TQVariant> - \value Palette a TQPalette - \value Pen a TQPen - \value Pixmap a TQPixmap - \value Point a TQPoint - \value PointArray a TQPointArray - \value Rect a TQRect - \value Region a TQRegion - \value Size a TQSize - \value SizePolicy a TQSizePolicy - \value String a TQString - \value CString a TQCString - \value StringList a TQStringList - \value Time a TQTime - \value UInt an unsigned int - - Note that TQt's definition of bool depends on the compiler. - \c tqglobal.h has the system-dependent definition of bool. -*/ - -/*! - Constructs an invalid variant. -*/ -TQVariant::TQVariant() -{ - d = new Private; -} - -/*! - Destroys the TQVariant and the contained object. - - Note that subclasses that reimplement clear() should reimplement - the destructor to call clear().
