And it&#39;s quite wonky, for example offering a list of QActions<br>
(QDeclarativeListProperty or QList, even with the payload casted to QObjects)<br>
does not seem to work. There&#39;s one, corrupt and therefore unusable entry in<br>
the returned data in the best case, no data at all in the worst.<br>
<br>
A workaround I&#39;ve found is to send a list of QActions (.name()) in a<br>
QStringList to the runtime, and offer a Q_INVOKABLE QAction* action(QString);<br>
accessor which returns a QAction* to the runtime.<br>
<br>
Your button has the following:<br>
<br>
property QtObject action<br>
<br>
onClicked: action.trigger()<br>
<br>
Then, in your delegate, you retrieve the action via the key you get in your<br>
&quot;listmodel&quot;:<br>
<br>
delegate: ActionButton {<br>
                        action: cpppluginthing.action(modelData)<br>
}<br>
<br>
Not the most beautiful thing in the world, but it seems to work at least. I&#39;m<br>
of course open to better solutions.<br>
