<h2>Detailed Description</h2>
<p>The QMessageId class provides a unique identifier for a <a href="qmessage.html">QMessage</a> message within the scope of the messaging store.</p>
<p>A QMessageId can be constructed from a string, or converted to a string with <a href="qmessageid.html#toString">toString</a>().</p>
<p>A QMessageId instance can be tested for validity with <a href="qmessageid.html#isValid">isValid</a>(), and compared to other instances for equality.</p>
<p>If the message a QMessageId identifies is removed from the messaging store then the identifier will not be reused.</p>
<p>The QMessageId implementation should be as small as is practical for the underlying platform.</p>

<h3 class="fn"><a name="toString"></a><span class="type"><a href="http://qt.nokia.com/doc/4.7/qstring.html">QString</a></span> QMessageId::<span class="name">toString</span> () const</h3>
<p>Returns the string representation of this identifier.</p>
<p>A null string should be returned if and only if the identifier is invalid.</p>
<p>String representations of identifiers should not be used to test for equality, instead the equality operator should be used.</p>
