<!-- $$$QMetaProperty-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QMetaProperty 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>(), and <a href="qmetaproperty.html#isStored">isStored</a>().</p>
<p>If the property is an enumeration, <a href="qmetaproperty.html#isEnumType">isEnumType</a>() returns true; if the property is an enumeration that is also a flag (i.e. 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>QMetaProperty objects can be copied by value. However, each copy will refer to the same underlying property meta-data.</p>
