This interface provides the basic mechanisms to display a list of completions, update this list according to user input, and allow the user to select a completion. </p> <p> Essentially, this provides an item view for the available completions. In order to use this interface, you will need to implement a CodeCompletionModel that generates the relevant completions given the current input. </p> <p> <b>Accessing the CodeCompletionInterface </b> </p> <p> The CodeCompletionInterface is an extension interface for a View, i.e. the View inherits the interface provided that the used KTextEditor library implements the interface. Use qobject_cast to access the interface: <pre class="fragment"> // view is of type KTextEditor.View* KTextEditor.CodeCompletionInterface *iface = qobject_cast<KTextEditor.CodeCompletionInterface*>( view ); if( iface ) { // the implementation supports the interface // do stuff } </pre> </p> <p> <b>Using the CodeCompletionInterface </b> </p> <p> The CodeCompletionInterface can be used in different ways, which we will call "automatic", and "manual". </p> <p> In automatic mode, the CodeCompletionInterface will take care of starting and aborting the generation of code completions as appropriate, when the users inserts or changes text. </p> <p> To use the interface in this way, first register a CodeCompletionModel using registerCompletionModel(). Now call setAutomaticCompletionEnabled() to enabled automatic completions. </p> <p> If you need more control over when code completions get shown or not, or which fragment of the text should be considered as the basis for generated completions, proceed as follows: </p> <p> Call setAutomaticCompletionEnabled(false) to disable automatic completions. To start the generation of code completions for the current word, call startCompletion(), with the appropriate parameters. To hide the generated completions, use abortCompletion(). </p> <p> <dl class="see" compact><dt><b>See also:</b></dt><dd> KTextEditor.View, KTextEditor.CodeCompletionModel </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="#abortCompletion">abortCompletion</a> (self)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#forceCompletion">forceCompletion</a> (self)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top">bool </td><td class="memItemRight" valign="bottom"><a class="el" href="#isAutomaticInvocationEnabled">isAutomaticInvocationEnabled</a> (self)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top">bool </td><td class="memItemRight" valign="bottom"><a class="el" href="#isCompletionActive">isCompletionActive</a> (self)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#registerCompletionModel">registerCompletionModel</a> (self, <a href="../ktexteditor/KTextEditor.CodeCompletionModel.html">KTextEditor.CodeCompletionModel</a> model)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#setAutomaticInvocationEnabled">setAutomaticInvocationEnabled</a> (self, bool enabled=1)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#startCompletion">startCompletion</a> (self, <a href="../ktexteditor/KTextEditor.Range.html">KTextEditor.Range</a> word, <a href="../ktexteditor/KTextEditor.CodeCompletionModel.html">KTextEditor.CodeCompletionModel</a> model)</td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top"> </td><td class="memItemRight" valign="bottom"><a class="el" href="#unregisterCompletionModel">unregisterCompletionModel</a> (self, <a href="../ktexteditor/KTextEditor.CodeCompletionModel.html">KTextEditor.CodeCompletionModel</a> model)</td></tr> </table> <hr><h2>Method Documentation</h2><a class="anchor" name="abortCompletion"></a> <div class="memitem"> <div class="memproto"> <table class="memname"><tr> <td class="memname"> abortCompletion</td> <td>(</td> <td class="paramtype"> </td> <td class="paramname"><em>self</em> )</td> <td width="100%"> </td> </tr> </table> </div> <div class="memdoc"><dl compact><dt><b>Abstract method:</b></dt><dd>This method is abstract and can be overridden but not called directly.</dd></dl><p>Abort the currently displayed code completion without executing any currently selected completion.
