<h2 id="details">Detailed Description</h2>
<p>The <a href="qprintpreviewwidget.html">QPrintPreviewWidget</a> class provides a widget for previewing page layouts for printer output.</p>
<p><a href="qprintpreviewdialog.html">QPrintPreviewDialog</a> uses a <a href="qprintpreviewwidget.html">QPrintPreviewWidget</a> internally, and the purpose of <a href="qprintpreviewwidget.html">QPrintPreviewWidget</a> is to make it possible to embed the preview into other widgets. It also makes it possible to build a different user interface around it than the default one provided with <a href="qprintpreviewdialog.html">QPrintPreviewDialog</a>.</p>
<p>Using <a href="qprintpreviewwidget.html">QPrintPreviewWidget</a> is straightforward:</p>
<ol class="1" type="1"><li>Create the <a href="qprintpreviewwidget.html">QPrintPreviewWidget</a><p>Construct the <a href="qprintpreviewwidget.html">QPrintPreviewWidget</a> either by passing in an existing <a href="qprinter.html">QPrinter</a> object, or have <a href="qprintpreviewwidget.html">QPrintPreviewWidget</a> create a default constructed <a href="qprinter.html">QPrinter</a> object for you.</p>
</li>
<li>Connect the <a href="qprintpreviewwidget.html#paintRequested">paintRequested</a>() signal to a slot.<p>When the widget needs to generate a set of preview pages, a <a href="qprintpreviewwidget.html#paintRequested">paintRequested</a>() signal will be emitted from the widget. Connect a slot to this signal, and draw onto the <a href="qprinter.html">QPrinter</a> passed in as a signal parameter. Call <a href="qprinter.html#newPage">QPrinter::newPage</a>(), to start a new page in the preview.</p>
</li>
