<a href="qvariant.html">QVariant</a> is expected. None will be
interpreted as an invalid QVariant.</p>
<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 class="cpp">
<span class="type"><a href="qdatastream.html">QDataStream</a></span> out(<span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>);
<span class="type">QVariant</span> v(<span class="number">123</span>); <span class="comment">// The variant now contains an int</span>
<span class="type">int</span> x <span class="operator">=</span> v<span class="operator">.</span><a href="qvariant.html#toInt">toInt</a>(); <span class="comment">// x = 123</span>
out <span class="operator"><</span><span class="operator"><</span> v; <span class="comment">// Writes a type tag and an int to out</span>
v <span class="operator">=</span> <span class="type">QVariant</span>(<span class="string">"hello"</span>); <span class="comment">// The variant now contains a QByteArray</span>
v <span class="operator">=</span> <span class="type">QVariant</span>(tr(<span class="string">"hello"</span>)); <span class="comment">// The variant now contains a QString</span>
<span class="type">int</span> y <span class="operator">=</span> v<span class="operator">.</span><a href="qvariant.html#toInt">toInt</a>(); <span class="comment">// y = 0 since v cannot be converted to an int</span>
<span class="type"><a href="qstring.html">QString</a></span> s <span class="operator">=</span> v<span class="operator">.</span><a href="qvariant.html#toString">toString</a>(); <span class="comment">// s = tr("hello") (see QObject.tr())</span>

in <span class="operator">></span><span class="operator">></span> v; <span class="comment">// Reads an Int variant</span>
<span class="type">int</span> z <span class="operator">=</span> v<span class="operator">.</span><a href="qvariant.html#toInt">toInt</a>(); <span class="comment">// z = 123</span>

v <span class="operator">=</span> <span class="type">QVariant</span>(<span class="type"><a href="qstringlist.html">QStringList</a></span>());
</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 can
have a defined type with no value set. However, note that QVariant
types can only be cast when they have had a value set.</p>
<pre class="cpp">
<span class="type">QVariant</span> x<span class="operator">,</span> y(<span class="type"><a href="qstring.html">QString</a></span>())<span class="operator">,</span> z(<span class="type"><a href="qstring.html">QString</a></span>(<span class="string">""</span>));
x<span class="operator">.</span><a href="qvariant.html#convert">convert</a>(<span class="type">QVariant</span><span class="operator">.</span>Int);
<span class="comment">// x.isNull() == true</span>
<span class="comment">// y.isNull() == true, z.isNull() == false</span>
</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
defined in <a href="qtgui.html">QtGui</a>, such as <a href="qcolor.html">QColor</a>, <a href="qimage.html">QImage</a>, and
<a href="qpixmap.html">QPixmap</a>. In other words, there is no
<tt>toColor()</tt> function. Instead, you can use the <a href="qvariant.html#value">QVariant.value</a>() or the <a href="qvariant.html#qvariant_cast">qvariant_cast</a>() template
function. For example:</p>
<pre class="cpp">
<span class="type">QVariant</span> variant;
<span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>
<span class="type"><a href="qcolor.html">QColor</a></span> color <span class="operator">=</span> variant<span class="operator">.</span>value<span class="operator"><</span><span class="type"><a href="qcolor.html">QColor</a></span><span class="operator">></span>();
</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 class="cpp">
<span class="type"><a href="qcolor.html">QColor</a></span> color <span class="operator">=</span> palette()<span class="operator">.</span>background()<span class="operator">.</span>color();
<span class="type">QVariant</span> variant <span class="operator">=</span> color;
</pre>

<h3>Using canConvert() and convert() Consecutively</h3>
<p>When using <a href="qvariant.html#canConvert">canConvert</a>()
and <a href="qvariant.html#convert">convert</a>() consecutively, it
is possible for <a href="qvariant.html#canConvert">canConvert</a>()
to return true, but <a href="qvariant.html#convert">convert</a>()
to return false. This is typically because <a href="qvariant.html#canConvert">canConvert</a>() only reports the
general ability of QVariant to convert between types given suitable
data; it is still possible to supply data which cannot actually be
converted.</p>
<p>For example, <a href="qvariant.html#canConvert">canConvert</a>()
would return true when called on a variant containing a string
because, in principle, QVariant is able to convert strings of
numbers to integers. However, if the string contains non-numeric
characters, it cannot be converted to an integer, and any attempt
to convert it will fail. Hence, it is important to have both
functions return true for a successful conversion.</p>
<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="Type-enum" />QVariant.Type</h3><p>This enum type defines the types of variable that a <a href="qvariant.html">QVariant</a> can contain.</p>

<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QVariant" />QVariant.__init__ (<i>self</i>)</h3><p>Constructs an invalid variant.</p>
<h3 class="fn"><a name="QVariant-2" />QVariant.__init__ (<i>self</i>, <a href="qtcore.html#Type-enum">Type</a> <i>type</i>)</h3><p>Constructs a null variant of type <i>type</i>.</p>
<h3 class="fn"><a name="QVariant-3" />QVariant.__init__ (<i>self</i>, int <i>typeOrUserType</i>, sip.voidptr <i>copy</i>)</h3><p>Constructs variant of type <i>typeOrUserType</i>, and
initializes with <i>copy</i> if <i>copy</i> is not 0.</p>
<p>Note that you have to pass the address of the variable you want
stored.</p>
<p>Usually, you never have to use this constructor, use <a href="qvariant.html#fromValue">QVariant.fromValue</a>() instead to
construct variants from the pointer types represented by
<tt>QMetaType.VoidStar</tt>, <tt>QMetaType.QObjectStar</tt> and
<tt>QMetaType.QWidgetStar</tt>.</p>

argument to this constructor.</p>
<h3 class="fn"><a name="canConvert" />bool QVariant.canConvert (<i>self</i>, <a href="qtcore.html#Type-enum">Type</a> <i>t</i>)</h3><p>Returns true if the variant's type can be cast to the requested

<h3 class="fn"><a name="type" /><a href="qtcore.html#Type-enum">Type</a> QVariant.type (<i>self</i>)</h3><p>Returns the storage type of the value stored in the variant.
Although this function is declared as returning <a href="qvariant.html#Type-enum">QVariant.Type</a>, the return value
should be interpreted as <a href="qmetatype.html#Type-enum">QMetaType.Type</a>. In particular,
<a href="qvariant.html#Type-enum">QVariant.UserType</a> is
returned here only if the value is equal or greater than <a href="qmetatype.html#Type-enum">QMetaType.User</a>.</p>
<p>Note that return values in the ranges <a href="qvariant.html#Type-enum">QVariant.Char</a> through <a href="qvariant.html#Type-enum">QVariant.RegExp</a> and <a href="qvariant.html#Type-enum">QVariant.Font</a> through <a href="qvariant.html#Type-enum">QVariant.Transform</a> correspond to the

<p>Pay particular attention when working with char and <a href="qchar.html">QChar</a> variants. Note that there is no <a href="qvariant.html">QVariant</a> constructor specifically for type
char, but there is one for <a href="qchar.html">QChar</a>. For a
variant of type <a href="qchar.html">QChar</a>, this function
returns <a href="qvariant.html#Type-enum">QVariant.Char</a>, which
is the same as <a href="qmetatype.html#Type-enum">QMetaType.QChar</a>, but for a variant
of type <tt>char</tt>, this function returns <a href="qmetatype.html#Type-enum">QMetaType.Char</a>, which is <i>not</i>
the same as <a href="qvariant.html#Type-enum">QVariant.Char</a>.</p>
<p>Also note that the types <tt>void*</tt>, <tt>long</tt>,
<tt>short</tt>, <tt>unsigned</tt> <tt>long</tt>, <tt>unsigned</tt>
<tt>short</tt>, <tt>unsigned</tt> <tt>char</tt>, <tt>float</tt>,
<tt>QObject*</tt>, and <tt>QWidget*</tt> are represented in
<a href="qmetatype.html#Type-enum">QMetaType.Type</a> but not in
<a href="qvariant.html#Type-enum">QVariant.Type</a>, and they can
be returned by this function. However, they are considered to be
user defined types when tested against <a href="qvariant.html#Type-enum">QVariant.Type</a>.</p>
<p>To test whether an instance of <a href="qvariant.html">QVariant</a> contains a data type that is
compatible with the data type you are interested in, use <a href="qvariant.html#canConvert">canConvert</a>().</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. The returned
strings describe the C++ datatype used to store the data: for
example, "<a href="qfont.html">QFont</a>", "<a href="qstring.html">QString</a>", or "<a href="qvariant.html#QVariantList-typedef">QVariantList</a>". An Invalid
variant returns 0.</p>
<h3 class="fn"><a name="typeToName" />str QVariant.typeToName (<a href="qtcore.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>
<p>Returns a null pointer if the type is <a href="qvariant.html#Type-enum">QVariant.Invalid</a> or doesn't
exist.</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
