<h1>ContainerInterface Class Reference</h1>
<code>from PyKDE4.ktexteditor import *</code>
<p>
Namespace: <a href="../ktexteditor/KTextEditor.html">KTextEditor</a><br />
<h2>Detailed Description</h2>
<p>Class that allows the kpart host to provide some extensions.
</p>
<p>
The KTextEditor framework allows the kpart host to provide additional
services to the kpart. Those services are provided through the
ContainerInterface class.
</p>
<p>
If the container supports those specific services, it should set an
instance of the service class with ContainerInterface.setContainer(). That
instance should inherit QObject, have the Q_OBJECT macro and declare a
Q_INTERFACES(), in order for the qobject_cast mechanism to work.
</p>
<p>
To obtain a ContainerInterface, in order to set a specific container
extension, the kpart host should do:
<pre class="fragment">
// inside the kpart host
Editor * editor = KTextEditor.EditorChooser.editor();
ContainerInterface * iface = qobject_cast<ContainerInterface *>( editor );
if (iface != NULL) {
iface->setContainer( myContainerExtension );
} else {
// the kpart does not support ContainerInterface.
}
</pre>
</p>
<p>
It is then up to the kpart to use it.
</p>

</p>
<p>
This method is used by the KTextEditor component to know
which extensions are supported by the KTextEditor host.
</p>
<p>
The kpart will cast the result with qobject_cast() to the right
container extension to see if that particular extension is supported:
</p>
<p>
<b>Example:</b>
<pre class="fragment">
// inside the kpart
Editor * editor = KTextEditor.EditorChooser.editor();
ContainerInterface * iface = qobject_cast<ConainterInterace *>( editor );
SomeContainerExtension * myExt =
qobject_cast<SomeContainerExtension *>( iface->container() );
if (myExt) {
// do some stuff with the specific container extension
// ...
} else {
// too bad, that extension is not supported.
}
</pre>
