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*
auto iface = qobject_cast<KTextEditor::DesiredExtensionInterface*>(doc);
 
if (iface) {
    // the implementation supports the interface
    // do stuff
} else {
    // the implementation does not support the interface
}
