<h2>Detailed Description</h2>
<p>The QPrintPreviewWidget class provides a widget for previewing page layouts for printer output.</p>
<p><a href="qprintpreviewdialog.html">QPrintPreviewDialog</a> uses a QPrintPreviewWidget internally, and the purpose of QPrintPreviewWidget 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 QPrintPreviewWidget is straightforward:</p>
<ol type="1">
<li>Create the QPrintPreviewWidget<p>Construct the QPrintPreviewWidget either by passing in an exisiting <a href="qprinter.html">QPrinter</a> object, or have QPrintPreviewWidget 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>
</ol>
