<h2>Detailed Description</h2>
<p>The QWebHistoryInterface class provides an interface to implement link history.</p>
<p>The QWebHistoryInterface is an interface that can be used to keep track of visited links. It contains two pure virtual methods that are called by the WebKit engine: <a href="qwebhistoryinterface.html#addHistoryEntry">addHistoryEntry</a>() is used to add urls that have been visited to the interface, while <a href="qwebhistoryinterface.html#historyContains">historyContains</a>() is used to query whether the given url has been visited by the user. By default the QWebHistoryInterface is not set, so WebKit does not keep track of visited links.</p>
<p><b>Note: </b>The history tracked by QWebHistoryInterface is not specific to an instance of <a href="qwebpage.html">QWebPage</a> but applies to all pages.</p></div>

<h3 class="fn"><a name="dtor.QWebHistoryInterface"></a>QWebHistoryInterface::<span class="name">~QWebHistoryInterface</span>()</h3>
<p>Destroys the interface. If this is currently the default interface it will be unset.</p>

<p>Called by WebKit to add another <i>url</i> to the list of visited pages.</p>
<!-- @@@addHistoryEntry -->
<!-- $$$defaultInterface[overload1]$$$defaultInterface -->
<h3 class="fn"><a name="defaultInterface"></a><span class="type">QWebHistoryInterface</span> * QWebHistoryInterface::<span class="name">defaultInterface</span>()<tt> [static]</tt></h3>
<p>Returns the default interface that will be used by WebKit. If no default interface has been set, WebKit will not keep track of visited links and a null pointer will be returned.</p>
<p><b>See also </b><a href="qwebhistoryinterface.html#setDefaultInterface">setDefaultInterface</a>().</p>
<!-- @@@defaultInterface -->
<!-- $$$historyContains[overload1]$$$historyContainsconstQString& -->
<h3 class="fn"><a name="historyContains"></a><span class="type">bool</span> QWebHistoryInterface::<span class="name">historyContains</span>(const <span class="type"><a href="../qtcore/qstring.html">QString</a></span> &<i> url</i>) const<tt> [pure virtual]</tt></h3>
<p>Called by the WebKit engine to query whether a certain <i>url</i> has been visited by the user already. Returns true if the <i>url</i> is part of the history of visited links; otherwise returns false.</p>
<!-- @@@historyContains -->
<!-- $$$setDefaultInterface[overload1]$$$setDefaultInterfaceQWebHistoryInterface* -->

<p>Sets a new default interface, <i>defaultInterface</i>, that will be used by all of WebKit to keep track of visited links.</p>
<p>If an interface without a parent has already been set, the old interface will be deleted. When the application exists <a href="qwebhistoryinterface.html">QWebHistoryInterface</a> will automatically delete the <i>defaultInterface</i> if it does not have a parent.</p>
