<hr><a name="details"></a><h2>Detailed Description</h2>
The QMetaObject class contains meta information about Qt objects.
<p>
<p> The Meta Object System in Qt is responsible for the signals and
slots inter-object communication mechanism, runtime type
information and the property system. All meta information in Qt is
kept in a single instance of QMetaObject per class.
<p> This class is not normally required for application programming.
But if you write meta applications, such as scripting engines or
GUI builders, you might find these functions useful:
<ul>
<li> <a href="#className">className</a>() to get the name of a class.
<li> <a href="#superClassName">superClassName</a>() to get the name of the superclass.
<li> <a href="#inherits">inherits</a>(), the function called by <a href="qobject.html#inherits">QObject::inherits</a>().
<li> <a href="#superClass">superClass</a>() to access the superclass's <a href="metaobjects.html#meta-object">meta object</a>.
<li> <a href="#numSlots">numSlots</a>(), <a href="#numSignals">numSignals</a>(), <a href="#slotNames">slotNames</a>(), and <a href="#signalNames">signalNames</a>() to get
information about a class's signals and slots.
<li> <a href="#property">property</a>() and <a href="#propertyNames">propertyNames</a>() to obtain information about a
class's properties.
</ul>
<p> Classes may have a list of name-value pairs of class information.
The number of pairs is returned by <a href="#numClassInfo">numClassInfo</a>(), and values are
returned by <a href="#classInfo">classInfo</a>().

<hr><h2>Member Function Documentation</h2>
<h3 class=fn>const QClassInfo * <a name="classInfo"></a>QMetaObject::classInfo ( int index, bool super = FALSE ) const
</h3>
Returns the class information with index <em>index</em> or 0 if no such
information exists.
<p> If <em>super</em> is TRUE, inherited class information is included.
<h3 class=fn>const char * <a name="classInfo-2"></a>QMetaObject::classInfo ( const char * name, bool super = FALSE ) const
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Returns the class information with name <em>name</em> or 0 if no such
information exists.
<p> If <em>super</em> is TRUE, inherited class information is included.
<h3 class=fn>const char * <a name="className"></a>QMetaObject::className () const
</h3>
<p> Returns the class name.
<p> <p>See also <a href="qobject.html#className">QObject::className</a>() and <a href="#superClassName">superClassName</a>().
<h3 class=fn>int <a name="findProperty"></a>QMetaObject::findProperty ( const char * name, bool super = FALSE ) const
</h3>
Returns the index for the property with name <em>name</em> or -1 if no
such property exists.
<p> If <em>super</em> is TRUE, inherited properties are included.
<p> <p>See also <a href="#property">property</a>() and <a href="#propertyNames">propertyNames</a>().
<h3 class=fn>bool <a name="inherits"></a>QMetaObject::inherits ( const char * clname ) const
</h3>
Returns TRUE if this class inherits <em>clname</em> within the <a href="metaobjects.html#meta-object">meta object</a> inheritance chain; otherwise returns FALSE.
<p> (A class is considered to inherit itself.)
<h3 class=fn>int <a name="numClassInfo"></a>QMetaObject::numClassInfo ( bool super = FALSE ) const
</h3>
Returns the number of items of class information available for
this class.
<p> If <em>super</em> is TRUE, inherited class information is included.
<h3 class=fn>int <a name="numProperties"></a>QMetaObject::numProperties ( bool super = FALSE ) const
</h3>
Returns the number of properties for this class.
<p> If <em>super</em> is TRUE, inherited properties are included.
<p> <p>See also <a href="#propertyNames">propertyNames</a>().
<h3 class=fn>int <a name="numSignals"></a>QMetaObject::numSignals ( bool super = FALSE ) const
</h3>
Returns the number of signals for this class.
<p> If <em>super</em> is TRUE, inherited signals are included.
<p> <p>See also <a href="#signalNames">signalNames</a>().
<h3 class=fn>int <a name="numSlots"></a>QMetaObject::numSlots ( bool super = FALSE ) const
</h3>
Returns the number of slots for this class.
<p> If <em>super</em> is TRUE, inherited slots are included.
<p> <p>See also <a href="#slotNames">slotNames</a>().
<h3 class=fn>const <a href="qmetaproperty.html">QMetaProperty</a> * <a name="property"></a>QMetaObject::property ( int index, bool super = FALSE ) const
</h3>
Returns the property meta data for the property at index <em>index</em>
or 0 if no such property exists.
<p> If <em>super</em> is TRUE, inherited properties are included.
<p> <p>See also <a href="#propertyNames">propertyNames</a>().
<h3 class=fn><a href="qstrlist.html">QStrList</a> <a name="propertyNames"></a>QMetaObject::propertyNames ( bool super = FALSE ) const
</h3>
Returns a list with the names of all this class's properties.
<p> If <em>super</em> is TRUE, inherited properties are included.
<p> <p>See also <a href="#property">property</a>().
<h3 class=fn><a href="qstrlist.html">QStrList</a> <a name="signalNames"></a>QMetaObject::signalNames ( bool super = FALSE ) const
</h3>
Returns a list with the names of all this class's signals.
<p> If <em>super</em> is TRUE, inherited signals are included.
<h3 class=fn><a href="qstrlist.html">QStrList</a> <a name="slotNames"></a>QMetaObject::slotNames ( bool super = FALSE ) const
</h3>
Returns a list with the names of all this class's slots.

<h3 class=fn><a href="qmetaobject.html">QMetaObject</a> * <a name="superClass"></a>QMetaObject::superClass () const
</h3>
<p> Returns the <a href="metaobjects.html#meta-object">meta object</a> of the super class or 0 if there is no
such object.
<h3 class=fn>const char * <a name="superClassName"></a>QMetaObject::superClassName () const
</h3>
<p> Returns the class name of the superclass or 0 if there is no
superclass in the <a href="qobject.html">QObject</a> hierachy.
