View Extension Interfaces

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