And it's quite wonky, for example offering a list of QActions 
(QDeclarativeListProperty or QList, even with the payload casted to QObjects) 
does not seem to work. There's one, corrupt and therefore unusable entry in 
the returned data in the best case, no data at all in the worst.

A workaround I've found is to send a list of QActions (.name()) in a 
QStringList to the runtime, and offer a Q_INVOKABLE QAction* action(QString); 
accessor which returns a QAction* to the runtime.

Your button has the following:

property QtObject action

onClicked: action.trigger()

Then, in your delegate, you retrieve the action via the key you get in your 

delegate: ActionButton {
		action: cpppluginthing.action(modelData)

Not the most beautiful thing in the world, but it seems to work at least. I'm 
of course open to better solutions.
