Ownership will be transferred to KFileDialog, so you have to create the preview with "new" and let KFileDialog delete it. </p> <p> Just derive your custom preview widget from KPreviewWidgetBase and implement all the pure virtual methods. The slot showPreview(const KUrl &) is called every time the file selection changes. </p> <p> Abstract baseclass for all preview widgets. <dl class="author" compact><dt><b>Author:</b></dt><dd> Frerich Raabe <raabe@kde.org> </dd></dl> </p> <table border="0" cellpadding="0" cellspacing="0"><tr><td colspan="2"><br><h2>Methods</h2></td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#KPreviewWidgetBase">__init__</a> (self, QWidget parent)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#KPreviewWidgetBase">__init__</a> (self, <a href="../kio/KPreviewWidgetBase.html">KPreviewWidgetBase</a> a0)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#clearPreview">clearPreview</a> (self)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#setSupportedMimeTypes">setSupportedMimeTypes</a> (self, QStringList mimeTypes)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#showPreview">showPreview</a> (self, <a href="../kdecore/KUrl.html">KUrl</a> url)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top">QStringList </td><td class="memItemRight" valign="bottom"><a class="el" href="#supportedMimeTypes">supportedMimeTypes</a> (self)</td></tr> </table> <hr><h2>Method Documentation</h2><a class="anchor" name="KPreviewWidgetBase"></a> <div class="memitem"> <div class="memproto"> <table class="memname"><tr> <td class="memname">__init__</td> <td>(</td> <td class="paramtype"> <em>self</em>, </td> <td class="paramname"></td> </tr><tr> <td class="memname"></td> <td></td> <td class="paramtype">QWidget </td> <td class="paramname"><em>parent</em></td> </tr> <tr> <td></td> <td>)</td> <td></td> <td></td> <td width="100%"> </td> </tr></table> </div> <div class="memdoc"><p>Constructor.
