KTextEditor

Command Extension Interfaces

A KTextEditor command-line Command can use extension interfaces, but it does not need to.

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

Use qobject_cast to cast a Command cmd into the DesiredExtensionInterface, example:

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