returning list to QML

[Jim Gir]

Hi,
I'm having trouble returning list from python to QML.
it's ok with @Property("QVariantList", notify=someNotifier) but I can't make it work with something like @Slot(resultat=list) or Slot(result = "QVariantList").
Thanks for help :-)

Hi,

You should provide a minimal code example that shows your problem.

[Jim Gir]

class Some(QObject):
  
   fakenotify = Signal()

   @Property('QVariantList', notify=fakenotify2)
    def withprop(self):
        with db_session:
            return self.db.Page.recents()

    @Slot(result=list)
    def withslot(self):
        with db_session:
            return self.db.Page.recents()

in some ListView using as model:
some.withprop works
but
some.whithslot() fails with : qrc:/qml/main.qml:54: TypeError: Cannot call method 'withslot' of null

Please provide a complete minimal test case including the qml you are using.

My bad, it's ok, I had to specify QVariantList in result and not list.
