+    \class TQVariant tqvariant.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 tqfind 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 tqcontains 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 tqcontains a TQCString
+    v = TQVariant(tr("hello"));// The variant now tqcontains 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
