<h1>SessionConfigInterface Class Reference</h1>

<h2>Detailed Description</h2>
<p>Session config interface extension for the Document, View and Plugin.
</p>
<p>
<b>Introduction </b>
</p>
<p>
The SessionConfigInterface is an extension for Documents, Views and Plugins
to add support for session-specific configuration settings.
readSessionConfig() is called whenever session-specific settings are to be
read from the given KConfig* and writeSessionConfig() whenever they are to
be written, for example when a session changed or was closed.
</p>
<p>
<dl class="note" compact><dt><b>Note:</b></dt><dd> A session does not have anything to do with an X-session under Unix.
What is meant is rather a context, think of sessions in Kate or
projects in KDevelop for example.
</dd></dl> </p>
<p>
<b>Adding Session Support </b>
</p>
<p>
To add support for sessions a KTextEditor implementation has to derive the
Document and View class from SessionConfigInterface and reimplement
readSessionConfig() and writeSessionConfig().
</p>
<p>
The same applies to a Plugin, read the detailed description for plugins.
</p>
<p>
<b>Accessing the SessionConfigInterface </b>
</p>
<p>
The SessionConfigInterface is supposed to be an extension interface for a
Document, a View or a Plugin, i.e. the Document/View/Plugin inherits the
interface provided that it implements the interface. Use qobject_cast to
access the interface:
<pre class="fragment">
// object is of type KTextEditor.Document* or View* or Plugin*
KTextEditor.SessionConfigInterface *iface =
qobject_cast<KTextEditor.SessionConfigInterface*>( object );
if( iface ) {
// interface is supported
// do stuff
}
</pre>

<p>
That means for example
- a Document should reload the file, restore all marks etc...
- a View should scroll to the last position and restore the cursor
position etc...
- a Plugin should restore session specific settings
- If no file is being loaded, because an empty new document is going to be displayed,
this function should emit ReadOnlyPart.completed
