Detailed Description
A KTextEditor implementation may implement a View extension interface, but it does not need to.So as a KTextEditor user you have to cast the View to the desired interface and then check, whether the cast returns NULL or the valid interface.
Use qobject_cast to cast a View view into the DesiredExtensionInterface, example:
// view is of type KTextEditor::View* KTextEditor::DesiredExtensionInterface *iface = qobject_cast<KTextEditor::DesiredExtensionInterface*>( view ); if( iface ) { // the implementation supports the interface // do stuff } else { // the implementation does not support the interface }
