<h1>CommandExtension Class Reference</h1>
<code>from PyKDE4.ktexteditor import *</code>
<p>
Namespace: <a href="../ktexteditor/KTextEditor.html">KTextEditor</a><br />
<h2>Detailed Description</h2>
<p>Extension interface for a Command.
</p>
<p>
<b>Introduction </b>
</p>
<p>
The CommandExtension extends the Command interface allowing to interact
with commands during typing. This allows for completion and for example
the isearch plugin. If you develop a command that wants to complete or
process text as the user types the arguments, or that has flags, you can
have your command inherit this class.
</p>
<p>
If your command supports flags return them by reimplementing
flagCompletions(). You can return your own KCompletion object if the
command has available completion data. If you want to interactively react
on changes return true in wantsToProcessText() for the given command
and reimplement processText().
