<div class="descr">
<h2>Detailed Description</h2>
<p>The QWebSettings class provides an object to store the settings used by <a href="qwebpage.html">QWebPage</a> and <a href="qwebframe.html">QWebFrame</a>.</p>
<p>Each <a href="qwebpage.html">QWebPage</a> object has its own QWebSettings object, which configures the settings for that page. If a setting is not configured, then it is looked up in the global settings object, which can be accessed using <a href="qwebsettings.html#globalSettings">globalSettings</a>().</p>
<p>QWebSettings allows configuration of browser properties, such as font sizes and families, the location of a custom style sheet, and generic attributes like JavaScript and plugins. Individual attributes are set using the <a href="qwebsettings.html#setAttribute">setAttribute</a>() function. The <a href="qwebsettings.html#WebAttribute-enum">WebAttribute</a> enum further describes each attribute.</p>
<p>QWebSettings also configures global properties such as the web page memory cache, icon database, local database storage and offline applications storage.</p>
<a name="enabling-plugins"></a>
<h3>Enabling Plugins</h3>
<p>Support for browser plugins can enabled by setting the <a href="qwebsettings.html#WebAttribute-enum">PluginsEnabled</a> attribute. For many applications, this attribute is enabled for all pages by setting it on the <a href="qwebsettings.html#globalSettings">global settings object</a>. Qt WebKit will always ignore this setting when processing Qt plugins. The decision to allow a Qt plugin is made by the client in its reimplementation of <a href="qwebpage.html#createPlugin">QWebPage::createPlugin</a>().</p>
<a name="web-application-support"></a>
<h3>Web Application Support</h3>
<p>WebKit provides support for features specified in <a href="http://www.w3.org/TR/html5/">HTML 5</a> that improve the performance and capabilities of Web applications. These include client-side (offline) storage and the use of a Web application cache.</p>
<p>Client-side (offline) storage is an improvement over the use of cookies to store persistent data in Web applications. Applications can configure and enable the use of an offline storage database by calling the <a href="qwebsettings.html#setOfflineStoragePath">setOfflineStoragePath</a>() with an appropriate file path, and can limit the quota for each application by calling <a href="qwebsettings.html#setOfflineStorageDefaultQuota">setOfflineStorageDefaultQuota</a>().</p>
