<!-- $$$QMetaProperty-description -->
<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qmetaproperty.html">QMetaProperty</a> class provides meta-data about a property.</p>
<p>Property meta-data is obtained from an object's meta-object. See <a href="qmetaobject.html#property">QMetaObject::property</a>() and <a href="qmetaobject.html#propertyCount">QMetaObject::propertyCount</a>() for details.</p>
<a name="property-meta-data"></a>
<h3 >Property Meta-Data</h3>
<p>A property has a <a href="qmetaproperty.html#name">name</a>() and a <a href="qmetaproperty.html#type">type</a>(), as well as various attributes that specify its behavior: <a href="qmetaproperty.html#isReadable">isReadable</a>(), <a href="qmetaproperty.html#isWritable">isWritable</a>(), <a href="qmetaproperty.html#isDesignable">isDesignable</a>(), <a href="qmetaproperty.html#isScriptable">isScriptable</a>(), <a href="qmetaproperty.html#revision">revision</a>(), and <a href="qmetaproperty.html#isStored">isStored</a>().</p>
<p>If the property is an enumeration, <a href="qmetaproperty.html#isEnumType">isEnumType</a>() returns <code>true</code>; if the property is an enumeration that is also a flag (i.e&#x2e; its values can be combined using the OR operator), <a href="qmetaproperty.html#isEnumType">isEnumType</a>() and <a href="qmetaproperty.html#isFlagType">isFlagType</a>() both return true. The enumerator for these types is available from <a href="qmetaproperty.html#enumerator">enumerator</a>().</p>
<p>The property's values are set and retrieved with <a href="qmetaproperty.html#read">read</a>(), <a href="qmetaproperty.html#write">write</a>(), and <a href="qmetaproperty.html#reset">reset</a>(); they can also be changed through <a href="qobject.html">QObject</a>'s set and get functions. See <a href="qobject.html#setProperty">QObject::setProperty</a>() and <a href="qobject.html#property">QObject::property</a>() for details.</p>
<a name="copying-and-assignment"></a>
<h3 >Copying and Assignment</h3>
<p><a href="qmetaproperty.html">QMetaProperty</a> objects can be copied by value. However, each copy will refer to the same underlying property meta-data.</p>

<p>Writes <i>value</i> as the property's value to the given <i>object</i>. Returns true if the write succeeded; otherwise returns <code>false</code>.</p>
<p>If <i>value</i> is not of the same type type as the property, a conversion is attempted. An empty QVariant() is equivalent to a call to <a href="qmetaproperty.html#reset">reset</a>() if this property is resetable, or setting a default-constructed object otherwise.</p>
