<!-- $$$QPrintPreviewDialog-description --> <div class="descr"> <h2>Detailed Description</h2> <p>The QPrintPreviewDialog class provides a dialog for previewing and configuring page layouts for printer output.</p> <p>Using QPrintPreviewDialog in your existing application is straightforward:</p> <ol class="1"> <li>Create the QPrintPreviewDialog.<p>You can construct a QPrintPreviewDialog with an existing <a href="qprinter.html">QPrinter</a> object, or you can have QPrintPreviewDialog create one for you, which will be the system default printer.</p> </li> <li>Connect the <a href="qprintpreviewdialog.html#paintRequested">paintRequested</a>() signal to a slot.<p>When the dialog needs to generate a set of preview pages, the <a href="qprintpreviewdialog.html#paintRequested">paintRequested</a>() signal will be emitted. You can use the exact same code for the actual printing as for having the preview generated, including calling <a href="qprinter.html#newPage">QPrinter::newPage</a>() to start a new page in the preview. Connect a slot to the <a href="qprintpreviewdialog.html#paintRequested">paintRequested</a>() signal, where you draw onto the <a href="qprinter.html">QPrinter</a> object that is passed into the slot.</p> </li> <li>Call <a href="qdialog.html#exec">exec</a>().<p>Call <a href="qdialog.html#exec">QPrintPreviewDialog::exec</a>() to show the preview dialog.</p> </li> </ol> <p>In Symbian, there is no support for printing.
