+/*!
+ \class TQVariant qvariant.h
+ \brief The TQVariant class acts like a union for the most common TQt data types.
+
+ \ingroup objectmodel
+ \ingroup misc
+ \mainclass
+
+ Because C++ forbids unions from including types that have
+ non-default constructors or destructors, most interesting TQt
+ classes cannot be used in unions. 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.
