Detailed Description

A KTextEditor implementation may implement a Document extension interface, but it does not need to.

So as a KTextEditor user you have to cast the Document to the desired interface and then check, whether the cast returns NULL or the valid interface.

Use qobject_cast to cast a Document doc into the DesiredExtensionInterface, example:

  // doc is of type KTextEditor::Document*
  KTextEditor::DesiredExtensionInterface *iface =
      qobject_cast<KTextEditor::DesiredExtensionInterface*>( doc );

  if( iface ) {
      // the implementation supports the interface
      // do stuff
  }
  else
  {
      // the implementation does not support the interface
  }
