<p>The QWebHistoryInterface is an interface that can be used to implement link history. It contains two pure virtual methods that are called by the <a href="examples.html#webkit">WebKit</a> engine. <a href="qwebhistoryinterface.html#addHistoryEntry">addHistoryEntry</a>() is used to add pages that have been visited to the interface, while <a href="qwebhistoryinterface.html#historyContains">historyContains</a>() is used to query whether this page has been visited by the user.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QWebHistoryInterface" />QWebHistoryInterface.__init__ (<i>self</i>, <a href="qobject.html">QObject</a> <i>parent</i> = None)</h3><p>The <i>parent</i> argument, if not None, causes <i>self</i> to be owned by Qt instead of PyQt.</p><p>Constructs a new <a href="qwebhistoryinterface.html">QWebHistoryInterface</a> with parent <i>parent</i>.</p>
<a name="//apple_ref/cpp/instm/QWebHistoryInterface/~QWebHistoryInterface" />
<h3 class="fn"><a name="addHistoryEntry" />QWebHistoryInterface.addHistoryEntry (<i>self</i>, QString)</h3><p>This method is abstract and should be reimplemented in any sub-class.</p><p>Called by <a href="examples.html#webkit">WebKit</a> to add another <i>url</i> to the list of visited pages.</p>
<a name="//apple_ref/cpp/clm/QWebHistoryInterface/defaultInterface" />
<h3 class="fn"><a name="defaultInterface" /><a href="qwebhistoryinterface.html">QWebHistoryInterface</a> QWebHistoryInterface.defaultInterface ()</h3><p>Returns the default interface that will be used by <a href="examples.html#webkit">WebKit</a>. If no default interface has been set, <a href="demos.html#qtwebkit">QtWebkit</a> will not track history.</p>
<p>See also <a href="qwebhistoryinterface.html#setDefaultInterface">setDefaultInterface</a>().</p>
<a name="//apple_ref/cpp/instm/QWebHistoryInterface/historyContains" />
<h3 class="fn"><a name="historyContains" />bool QWebHistoryInterface.historyContains (<i>self</i>, QString)</h3><p>This method is abstract and should be reimplemented in any sub-class.</p><p>Called by the <a href="examples.html#webkit">WebKit</a> 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>
<a name="//apple_ref/cpp/clm/QWebHistoryInterface/setDefaultInterface" />
<h3 class="fn"><a name="setDefaultInterface" />QWebHistoryInterface.setDefaultInterface (<a href="qwebhistoryinterface.html">QWebHistoryInterface</a>)</h3><p>Sets a new default interface, <i>defaultInterface</i>, that will be used by all of <a href="examples.html#webkit">WebKit</a> for managing history.</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>
