name="details" /><hr /><h2>Detailed Description</h2><p>The QVariant class acts like a union for the most common Qt data types.</p>
<p>Because C++ forbids unions from including types that have non-default constructors or destructors, most interesting Qt classes cannot be used in unions. Without QVariant, this would be a problem for <a href="qobject.html#property">QObject.property</a>() and for database work, etc.</p>
<p>A QVariant object holds a single value of a single <a href="qvariant.html#type">type</a>() at a time. (Some <a href="qvariant.html#type">type</a>()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 <a href="qvariant.html#convert">convert</a>(), get its value using one of the toT() functions (e.g., <a href="qvariant.html#toSize">toSize</a>()) and check whether the type can be converted to a particular type using <a href="qvariant.html#canConvert">canConvert</a>().</p>
<p>The methods named toT() (e.g., <a href="qvariant.html#toInt">toInt</a>(), <a href="qvariant.html#toString">toString</a>()) 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.</p>
<p>Here is some example code to demonstrate the use of QVariant:</p>
<pre>
QDataStream out(...);
QVariant 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 = QVariant("hello"); // The variant now contains a QByteArray
v = QVariant(tr("hello")); // The variant now contains a QString
int y = v.toInt(); // y = 0 since v cannot be converted to an int
QString s = v.toString(); // s = tr("hello") (see QObject.tr())
out << v; // Writes a type tag and a QString to out
...
QDataStream 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 = v.toInt() + 100; // The variant now hold the value 223
v = QVariant(QStringList());
</pre>
<p>You can even store <a href="qlist.html">QList</a><QVariant> and <a href="qmap.html">QMap</a><<a href="qstring.html">QString</a>, QVariant> values 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.</p>
<p>QVariant also supports the notion of null values, where you have a defined type with no value set.</p>
<pre>
QVariant x, y(QString()), z(QString(""));
x.convert(QVariant.Int);
// x.isNull() == true
// y.isNull() == true, z.isNull() == false
// y.isEmpty() == true, z.Empty() == true
</pre>
<p>QVariant can be extended to support other types than those mentioned in the <a href="qvariant.html#Type-enum">Type</a> enum. See the <a href="qmetatype.html">QMetaType</a> documentation for details.</p>
<a id="a-note-on-gui-types" name="a-note-on-gui-types" />
<h3>A Note on GUI Types</h3>
<p>Because QVariant is part of the <a href="qtcore.html">QtCore</a> library, it cannot provide conversion functions to data types such as <a href="qcolor.html">QColor</a>, <a href="qimage.html">QImage</a>, and <a href="qpixmap.html">QPixmap</a>, which are part of <a href="qtgui.html">QtGui</a>. In other words, there is no <tt>toColor()</tt> function.</p>
<p>Instead, you can use the <a href="qvariant.html#value">QVariant.value</a>() or the <a href="qvariant.html#qVariantValue">qVariantValue</a>() template function. For example:</p>
<pre>
QVariant variant;
...
QColor color = variant.value<QColor>();
</pre>
<p>The inverse conversion (e.g., from <a href="qcolor.html">QColor</a> to QVariant) is automatic for all data types supported by QVariant, including GUI-related types:</p>
<pre>
QColor color = palette().background().color();
QVariant variant = color;
</pre>
<p>See also <a href="qmetatype.html">QMetaType</a>.</p>

<h3 class="fn"><a name="toUInt" />(unsigned long, bool <i>ok</i>) QVariant.toUInt (<i>self</i>)</h3><p>Returns the variant as an unsigned int if the variant has <a href="qvariant.html#type">type</a>() <a href="qvariant.html#Type-enum">UInt</a>, <a href="qvariant.html#Type-enum">Bool</a>, <a href="qvariant.html#Type-enum">ByteArray</a>, <a href="qvariant.html#Type-enum">Char</a>, <a href="qvariant.html#Type-enum">Double</a>, <a href="qvariant.html#Type-enum">Int</a>, <a href="qvariant.html#Type-enum">LongLong</a>, <a href="qvariant.html#Type-enum">String</a>, or <a href="qvariant.html#Type-enum">ULongLong</a>; otherwise returns 0.</p>
<p>If <i>ok</i> is non-null: <tt>*</tt><i>ok</i> is set to true if the value could be converted to an unsigned int; otherwise <tt>*</tt><i>ok</i> is set to false.</p>

<h3 class="fn"><a name="toUrl" /><a href="qurl.html">QUrl</a> QVariant.toUrl (<i>self</i>)</h3><p>Returns the variant as a <a href="qurl.html">QUrl</a> if the variant has <a href="qvariant.html#type">type</a>() <a href="qvariant.html#Type-enum">Url</a>; otherwise returns an invalid <a href="qurl.html">QUrl</a>.</p>

<h3 class="fn"><a name="type" /><a href="qvariant.html#Type-enum">Type</a> QVariant.type (<i>self</i>)</h3><p>Returns the storage type of the value stored in the variant. Usually it's best to test with <a href="qvariant.html#canConvert">canConvert</a>() whether the variant can deliver the data type you are interested in.</p>
<h3 class="fn"><a name="typeName" />str QVariant.typeName (<i>self</i>)</h3><p>Returns the name of the type stored in the variant.

An Invalid variant returns 0.</p>
<h3 class="fn"><a name="typeToName" />str QVariant.typeToName (<a href="qvariant.html#Type-enum">Type</a> <i>type</i>)</h3><p>Converts the enum representation of the storage type, <i>typ</i>, to its string representation.</p>
<h3 class="fn"><a name="userType" />int QVariant.userType (<i>self</i>)</h3><p>Returns the storage type of the value stored in the variant. For non-user types, this is the same as <a href="qvariant.html#type">type</a>().</p>
