<h3 class="fn"><a name="QObject-3"></a>QObject::QObject ( QObject * <i>parent</i>, const char * <i>name</i> )</h3>
<p>This function overloads <a href="qobject.html#QObject">QObject</a>().</p>
<p>Creates a new <a href="qobject.html">QObject</a> with the given <i>parent</i> and object <i>name</i>.</p>
<a name="//apple_ref/cpp/instm/QObject/checkConnectArgs"></a>
<h3 class="fn"><a name="checkConnectArgs"></a>bool QObject::checkConnectArgs ( const char * <i>signal</i>, const QObject * <i>object</i>, const char * <i>method</i> ) <tt> [protected]</tt></h3>
<p>Use <a href="qmetaobject.html#checkConnectArgs">QMetaObject::checkConnectArgs</a>() instead.</p>
<a name="//apple_ref/cpp/instm/QObject/child"></a>
<h3 class="fn"><a name="child"></a>QObject * QObject::child ( const char * <i>objName</i>, const char * <i>inheritsClass</i> = 0, bool <i>recursiveSearch</i> = true ) const</h3>
<p>Searches the children and optionally grandchildren of this object, and returns a child that is called <i>objName</i> that inherits <i>inheritsClass</i>. If <i>inheritsClass</i> is 0 (the default), any class matches.</p>
<p>If <i>recursiveSearch</i> is true (the default), child() performs a depth-first search of the object's children.</p>
<p>If there is no such object, this function returns 0. If there are more than one, the first one found is returned.</p>
<a name="//apple_ref/cpp/instm/QObject/className"></a>
<h3 class="fn"><a name="className"></a>const char * QObject::className () const</h3>
<p>Use <a href="qobject.html#metaObject">metaObject</a>()->className() instead.</p>
<a name="//apple_ref/cpp/instm/QObject/insertChild"></a>
<h3 class="fn"><a name="insertChild"></a>void QObject::insertChild ( QObject * <i>object</i> )</h3>
<p>Use <a href="qobject.html#setParent">setParent</a>() instead, i.e., call object->setParent(this).</p>
<a name="//apple_ref/cpp/instm/QObject/isA"></a>
<h3 class="fn"><a name="isA"></a>bool QObject::isA ( const char * <i>className</i> ) const</h3>
<p>Compare <i>className</i> with the object's <a href="qobject.html#metaObject">metaObject</a>()-><a href="qobject-qt3.html#className">className</a>() instead.</p>
<a name="//apple_ref/cpp/instm/QObject/name"></a>
<h3 class="fn"><a name="name"></a>const char * QObject::name () const</h3>
<p>Use <a href="qobject.html#objectName-prop">objectName</a>() instead.</p>
<p>See also <a href="qobject-qt3.html#setName">setName</a>().</p>
<h3 class="fn"><a name="name-2"></a>const char * QObject::name ( const char * <i>defaultName</i> ) const</h3>
<p>Use <a href="qobject.html#objectName-prop">objectName</a>() instead.</p>
<a name="//apple_ref/cpp/clm/QObject/normalizeSignalSlot"></a>
<h3 class="fn"><a name="normalizeSignalSlot"></a><a href="qbytearray.html">QByteArray</a> QObject::normalizeSignalSlot ( const char * <i>signalSlot</i> ) <tt> [static protected]</tt></h3>

<a name="//apple_ref/cpp/instm/QObject/removeChild"></a>
<h3 class="fn"><a name="removeChild"></a>void QObject::removeChild ( QObject * <i>object</i> )</h3>
<p>Use <a href="qobject.html#setParent">setParent</a>() instead, i.e., call object->setParent(0).</p>
