<h2 id="details">Detailed Description</h2>
<p>The <a href="qdbusabstractadaptor.html">QDBusAbstractAdaptor</a> class is the base class of D-Bus adaptor classes.</p>
<p>The <a href="qdbusabstractadaptor.html">QDBusAbstractAdaptor</a> 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 <a href="qdbusabstractadaptor.html">QDBusAbstractAdaptor</a> to a normal <a href="../qtcore/qobject.html">QObject</a> and then registering that <a href="../qtcore/qobject.html">QObject</a> with <a href="qdbusconnection.html#registerObject">QDBusConnection::registerObject</a>. <a href="qdbusabstractadaptor.html">QDBusAbstractAdaptor</a> 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 <a href="qdbusabstractadaptor.html">QDBusAbstractAdaptor</a>-derived class should define the D-Bus interface it is implementing using the <a href="../qtcore/qobject.html#Q_CLASSINFO">Q_CLASSINFO</a> macro in the class definition. Note that only one interface can be exposed in this way.</p>
<p><a href="qdbusabstractadaptor.html">QDBusAbstractAdaptor</a> uses the standard <a href="../qtcore/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 <a href="qdbusabstractadaptor.html">QDBusAbstractAdaptor</a>-derived classes will be automatically be relayed through any D-Bus connections the object is registered on.</p>
<p>Classes derived from <a href="qdbusabstractadaptor.html">QDBusAbstractAdaptor</a> 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>Returns <code>true</code> if automatic signal relaying from the real object (see object()) is enabled, otherwiser returns <code>false</code>.</p>

<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>

<h2>Macro Documentation</h2>
<!-- $$$Q_NOREPLY[overload1]$$$Q_NOREPLY -->
<h3 class="fn" id="Q_NOREPLY"><a name="Q_NOREPLY"></a><span class="name">Q_NOREPLY</span></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 class="cpp">
Q_NOREPLY <span class="type">void</span> 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>
