<h2>Detailed Description</h2>
<p>The QDBusAbstractAdaptor class is the base class of D-Bus adaptor classes.</p>
<p>The QDBusAbstractAdaptor class is the starting point for all objects intending to provide interfaces to the external world using D-Bus. This is accomplished by attaching a one or more classes derived from QDBusAbstractAdaptor to a normal <a href="qobject.html">QObject</a> and then registering that <a href="qobject.html">QObject</a> with QDBusConnection::registerObject. QDBusAbstractAdaptor objects are intended to be light-weight wrappers, mostly just relaying calls into the real object (its parent) and the signals from it.</p>
<p>Each QDBusAbstractAdaptor-derived class should define the D-Bus interface it is implementing using the Q_CLASSINFO macro in the class definition.</p>
<p>QDBusAbstractAdaptor uses the standard <a href="qobject.html">QObject</a> mechanism of signals, slots and properties to determine what signals, methods and properties to export to the bus. Any signal emitted by QDBusAbstractAdaptor-derived classes will be automatically be relayed through any D-Bus connections the object is registered on.</p>
<p>Classes derived from QDBusAbstractAdaptor must be created on the heap using the <i>new</i> operator and must not be deleted by the user (they will be deleted automatically when the object they are connected to is also deleted).</p>
<p>See also <a href="usingadaptors.html">Using adaptors</a> and <a href="qdbusconnection.html">QDBusConnection</a>.</p>

<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="QDBusAbstractAdaptor"></a>QDBusAbstractAdaptor::QDBusAbstractAdaptor ( <a href="qobject.html">QObject</a> * <i>obj</i> ) <tt> [protected]</tt></h3>
<p>Constructs a <a href="qdbusabstractadaptor.html">QDBusAbstractAdaptor</a> with <i>obj</i> as the parent object.</p>
<h3 class="fn"><a name="dtor.QDBusAbstractAdaptor"></a>QDBusAbstractAdaptor::~QDBusAbstractAdaptor ()</h3>
<p>Destroys the adaptor.</p>
<p><b>Warning:</b> Adaptors are destroyed automatically when the real object they refer to is destroyed. Do not delete the adaptors yourself.</p>
<h3 class="fn"><a name="autoRelaySignals"></a>bool QDBusAbstractAdaptor::autoRelaySignals () const <tt> [protected]</tt></h3>
<p>Returns true if automatic signal relaying from the real object (see object()) is enabled, otherwiser returns false.</p>
<p>See also <a href="qdbusabstractadaptor.html#setAutoRelaySignals">setAutoRelaySignals</a>().</p>
<h3 class="fn"><a name="setAutoRelaySignals"></a>void QDBusAbstractAdaptor::setAutoRelaySignals ( bool <i>enable</i> ) <tt> [protected]</tt></h3>
<p>Toggles automatic signal relaying from the real object (see object()).</p>
<p>Automatic signal relaying consists of signal-to-signal connection of the signals on the parent that have the exact same method signatue in both classes.</p>
<p>If <i>enable</i> is set to true, connect the signals; if set to false, disconnect all signals.</p>
<p>See also <a href="qdbusabstractadaptor.html#autoRelaySignals">autoRelaySignals</a>().</p>

<h2>Macro Documentation</h2>
<h3 class="fn"><a name="Q_NOREPLY"></a>Q_NOREPLY</h3>
<p>The Q_NOREPLY macro can be used to mark a method to be called and not wait for it to finish processing before returning from <a href="qdbusabstractinterface.html#call">QDBusInterface::call</a>(). The called method cannot return any output arguments and, if it does, any such arguments will be discarded.</p>
<p>You can use this macro in your own adaptors by placing it before your method's return value (which must be "void") in the class declaration, as shown in the example:</p>
<pre> Q_NOREPLY void myMethod();</pre>
<p>Its presence in the method implementation (outside the class declaration) is optional.</p>
<p>This function was introduced in Qt 4.2.</p>
