provides an object to view and edit web
documents.</p>
<p>QWebPage holds a main frame responsible for web content,
settings, the history of navigated links and actions. This class
can be used, together with <a href="qwebframe.html">QWebFrame</a>,
to provide functionality like <a href="qwebview.html">QWebView</a>
in a widget-less environment.</p>
<p>QWebPage's API is very similar to <a href="qwebview.html">QWebView</a>, as you are still provided with common
functions like <a href="qwebpage.html#action">action</a>() (known
as <a href="qwebview.html#pageAction">pageAction</a>() in <a href="qwebview.html">QWebView</a>), <a href="qwebpage.html#triggerAction">triggerAction</a>(), <a href="qwebpage.html#findText">findText</a>() and <a href="qwebpage.html#settings">settings</a>(). More <a href="qwebview.html">QWebView</a>-like functions can be found in the
main frame of QWebPage, obtained via the <a href="qwebpage.html#mainFrame">mainFrame</a>() function. For example,
the <a href="qwebframe.html#load">load</a>(), <a href="qwebframe.html#url-prop">setUrl</a>() and <a href="qwebframe.html#setHtml">setHtml</a>() functions for QWebPage can
be accessed using <a href="qwebframe.html">QWebFrame</a>.</p>
<p>The <a href="qwebpage.html#loadStarted">loadStarted</a>() signal
is emitted when the page begins to load.The <a href="qwebpage.html#loadProgress">loadProgress</a>() signal, on the
other hand, is emitted whenever an element of the web page
completes loading, such as an embedded image, a script, etc.
Finally, the <a href="qwebpage.html#loadFinished">loadFinished</a>() signal is emitted
when the page contents are loaded completely, independent of script
execution or page rendering. Its argument, either true or false,
indicates whether or not the load operation succeeded.</p>

<h3>Using QWebPage in a Widget-less Environment</h3>
<p>Before you begin painting a QWebPage object, you need to set the
size of the viewport by calling <a href="qwebpage.html#viewportSize-prop">setViewportSize</a>(). Then, you
invoke the main frame's render function (<a href="qwebframe.html#render">QWebFrame.render</a>()). An example of
this is shown in the code snippet below.</p>
<p>Suppose we have a <tt>Thumbnail</tt> class as follows:</p>
<pre class="cpp">
<span class="keyword">class</span> Thumbnailer : <span class="keyword">public</span> <span class="type"><a href="qobject.html">QObject</a></span>
{
Q_OBJECT
<span class="keyword">public</span>:
Thumbnailer(<span class="keyword">const</span> <span class="type"><a href="qurl.html">QUrl</a></span> <span class="operator">&</span>url);
<span class="keyword">signals</span>:
<span class="type">void</span> finished();
<span class="keyword">private</span> <span class="keyword">slots</span>:
<span class="type">void</span> render();
<span class="keyword">private</span>:
<span class="type">QWebPage</span> page;
};
</pre>
<p>The <tt>Thumbnail</tt>'s constructor takes in a <i>url</i>. We
connect our QWebPage object's <a href="qwebpage.html#loadFinished">loadFinished()</a> signal to our
private slot, <tt>render()</tt>.</p>
<pre class="cpp">
Thumbnailer<span class="operator">.</span>Thumbnailer(<span class="keyword">const</span> <span class="type"><a href="qurl.html">QUrl</a></span> <span class="operator">&</span>url)
{
page<span class="operator">.</span>mainFrame()<span class="operator">-</span><span class="operator">></span>load(url);
connect(<span class="operator">&</span>page<span class="operator">,</span> SIGNAL(loadFinished(<span class="type">bool</span>))<span class="operator">,</span>
<span class="keyword">this</span><span class="operator">,</span> SLOT(render()));
}
</pre>
<p>The <tt>render()</tt> function shows how we can paint a
thumbnail using a QWebPage object.</p>
<pre class="cpp">
<span class="type">void</span> Thumbnailer<span class="operator">.</span>render()
{
page<span class="operator">.</span>setViewportSize(page<span class="operator">.</span>mainFrame()<span class="operator">-</span><span class="operator">></span>contentsSize());
<span class="type"><a href="qimage.html">QImage</a></span> image(page<span class="operator">.</span>viewportSize()<span class="operator">,</span> <span class="type"><a href="qimage.html">QImage</a></span><span class="operator">.</span>Format_ARGB32);
<span class="type"><a href="qpainter.html">QPainter</a></span> painter(<span class="operator">&</span>image);
page<span class="operator">.</span>mainFrame()<span class="operator">-</span><span class="operator">></span>render(<span class="operator">&</span>painter);
painter<span class="operator">.</span>end();
<span class="type"><a href="qimage.html">QImage</a></span> thumbnail <span class="operator">=</span> image<span class="operator">.</span>scaled(<span class="number">400</span><span class="operator">,</span> <span class="number">400</span>);
thumbnail<span class="operator">.</span>save(<span class="string">"thumbnail.png"</span>);
<span class="keyword">emit</span> finished();
}
</pre>
<p>We begin by setting the <a href="qwebpage.html#viewportSize-prop">viewportSize</a> and then we
instantiate a <a href="qimage.html">QImage</a> object,
<tt>image</tt>, with the same size as our <a href="qwebpage.html#viewportSize-prop">viewportSize</a>. This image is
then sent as a parameter to <tt>painter</tt>. Next, we render the
contents of the main frame and its subframes into <tt>painter</tt>.
Finally, we save the scaled image.</p>

<p>The behavior of this function is determined by <i>extension</i>.
The <i>option</i> and <i>output</i> values are typically casted to
the corresponding types (for example, <a href="qwebpage-choosemultiplefilesextensionoption.html">ChooseMultipleFilesExtensionOption</a>

<p>If the <a href="qwebpage.html#FindFlag-enum">HighlightAllOccurrences</a> flag is
not passed, the function will select an occurrence and all

one.</p>

<p>The configuration is also dependent on the device screen size
which is obtained automatically. For testing purposes the size can
be overridden by setting two environment variables
QTWEBKIT_DEVICE_WIDTH and QTWEBKIT_DEVICE_HEIGHT, which both needs
to be set.</p>
<p>The <a href="qwebpage-viewportattributes.html">ViewportAttributes</a> includes
a pixel density ratio, which will also be exposed to the web author
though the -webkit-pixel-ratio media feature. This is the ratio
between 1 density-independent pixel (DPI) and physical pixels.</p>
<p>A density-independent pixel is equivalent to one physical pixel
on a 160 DPI screen, so on our platform assumes that as the
baseline density.</p>
<p>The conversion of DIP units to screen pixels is quite
simple:</p>
<p>pixels = DIPs * (density / 160).</p>
<p>Thus, on a 240 DPI screen, 1 DIPs would equal 1.5 physical
pixels.</p>
<p>An invalid instance will be returned in the case an empty size
is passed to the method.</p>
<p><b>Note:</b> The density is automatically obtained from the DPI
of the screen where the page is being shown, but as many X11
servers are reporting wrong DPI, it is possible to override it
using <a href="qx11info.html#setAppDpiY">QX11Info.setAppDpiY</a>().</p>
