A plugin can handle several documents and views. For every document the plugin should handle addDocument() is called and for every view addView(). </p> <p> <b>Configuration Management </b> </p> <p> To do: write docu about config pages (new with kpluginmanager) To do: write docu about save/load settings (related to config page) </p> <p> <b>Session Management </b> </p> <p> As an extension a Plugin can implement the SessionConfigInterface. This interface provides functions to read and write session related settings. If you have session dependent data additionally derive your Plugin from this interface and implement the session related functions, for example: <pre class="fragment"> class MyPlugin : public KTextEditor.Plugin, public KTextEditor.SessionConfigInterface { Q_OBJECT Q_INTERFACES(KTextEditor.SessionConfigInterface) // ... virtual void readSessionConfig (const KConfigGroup& config); virtual void writeSessionConfig (KConfigGroup& config); }; </pre> </p> <p> <b>Plugin Architecture </b> </p> <p> After the plugin is loaded the editor implementation should call addDocument() and addView() for all documents and views the plugin should handle. If your plugin has a GUI it is common to add an extra class, like: <pre class="fragment"> class PluginView : public QObject, public KXMLGUIClient { Q_OBJECT public: // Constructor and other methods PluginView( KTextEditor.View* view ) : QObject( view ), KXMLGUIClient( view ), m_view( view ) { ... } // ... private: KTextEditor.View* m_view; }; </pre> Your KTextEditor.Plugin derived class then will create a new PluginView for every View, i.e. for every call of addView(). </p> <p> The method removeView() will be called whenever a View is removed/closed. If you have a PluginView for every view this is the place to remove it. </p> <p> <dl class="see" compact><dt><b>See also:</b></dt><dd> KTextEditor.Editor, KTextEditor.Document, KTextEditor.View, KTextEditor.SessionConfigInterface </dd></dl> <dl class="author" compact><dt><b>Author:</b></dt><dd> Christoph Cullmann <cullmann@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="#Plugin">__init__</a> (self, QObject parent)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#addDocument">addDocument</a> (self, <a href="../ktexteditor/KTextEditor.Document.html">KTextEditor.Document</a> document)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#addView">addView</a> (self, <a href="../ktexteditor/KTextEditor.View.html">KTextEditor.View</a> view)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#removeDocument">removeDocument</a> (self, <a href="../ktexteditor/KTextEditor.Document.html">KTextEditor.Document</a> document)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#removeView">removeView</a> (self, <a href="../ktexteditor/KTextEditor.View.html">KTextEditor.View</a> view)</td></tr> </table> <hr><h2>Method Documentation</h2><a class="anchor" name="Plugin"></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">QObject </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. </p> <p> Create a new plugin. </p><dl compact><dt><b>Parameters:</b></dt><dd> <table border="0" cellspacing="2" cellpadding="0"> <tr><td></td><td valign="top"><em>parent</em> </td><td> parent object </td></tr> </table></dl> <p> </p></div></div><a class="anchor" name="addDocument"></a> <div class="memitem"> <div class="memproto"> <table class="memname"><tr> <td class="memname"> addDocument</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"><a href="../ktexteditor/KTextEditor.Document.html">KTextEditor.Document</a> </td> <td class="paramname"><em>document</em></td> </tr> <tr> <td></td> <td>)</td> <td></td> <td></td> <td width="100%"> </td> </tr></table> </div> <div class="memdoc"><p>Add a new <b>document</b> to the plugin.
