<hr><h2><a name="details"></a>Detailed Description</h2>
The QMetaObject class contains meta information about Qt objects.
<p>
The Meta Object System in Qt is responsible for the signal/slot
mechanism for communication between objects, runtime type
information and the property system. All meta information in Qt is
kept in a single instance of QMetaObject per class.
<p>In general, you will not have to use this class directly in any
application program. Most of the class members and functions are
internal, <strong> do not use them </strong>.
<p>Some functions, however, are marked as public API and may make sense
for certain "meta" applications such as scripting engines or GUI
builders:
<ul>
<li> <a href="#e8bcda">className</a>() to get the name of a class.
<li> <a href="#3ab140">superClassName</a>() to get the name of the superclass.
<li> <a href="#7314ac">inherits</a>(), the function called by <a href="qobject.html#beb5d8">QObject::inherits</a>().
<li> <a href="#99683a">superClass</a>() to access the meta object of the superclass.
<li> <a href="#04ea03">numSlots</a>(), <a href="#e1d01d">numSignals</a>(), <a href="#d347e1">slotNames</a>() and  <a href="#ce8c4d">signalNames</a>() to get
information about a classes signals and slots.
<li> <a href="#843ead">property</a>() and <a href="#8c9b9c">propertyNames</a>() to receive information about a
classes properties.
<li> <a href="#37c0e2">classInfo</a>() and <a href="#937e7c">numClassInfo</a>() to access additional class information.
</ul>
