Issue: Transferring a class that inherits QAbstractListModel via QtRO

big fly

Hi all:
Has anyone used QtRO to transfer a custom ListModel implemented by inheriting QAbstractListModel? Could you please explain why the client keeps failing to initialize during the sharing process?
code:

//Hostmain.cpp
QRemoteObjectHost host(QUrl("local:orders"));
OrderModel2 *model = new OrderModel2;
 host.enableRemoting(static_cast<QAbstractItemModel*>(model), "OrderModel2");

//Replica.cpp
QRemoteObjectNode repNode;
bool ret = repNode.connectToNode(QUrl("local:orders"));
qDebug() << "client connectToNode: " << ret;
QAbstractItemModelReplica * replica = repNode.acquireModel("OrderModel2");

log:
qt.remoteobjects:  newObjects: QList(ObjectInfo("OrderModel2", "", "") )
qt.remoteobjects:    connectedSources.contains( ObjectInfo("OrderModel2", "", "") ) false true
qt.remoteobjects: setConnection started LocalClientIo(0x559a4be625e0) "OrderModel2"
qt.remoteobjects:  InitPacket--> "OrderModel2" 0x559a4be42c90
qt.remoteobjects: initialize() 2
qt.remoteobjects: Send 0 "replicaSizeRequest" 18 QList(QVariant(QList<QtPrivate::ModelIndex>, QList())) LocalClientIo(0x559a4be625e0)
qt.remoteobjects: Sent InvokePacket with serial id: 1
qt.remoteobjects: isSet = true for "OrderModel2"

Hi and welcome to devnet,

I can't currently but: did you follow this example ?

Hi:
Thank you for your reply.
I have solved the transfer issue; it turned out I was using the wrong Function Overloading.

//Hostmain.cpp
QRemoteObjectHost host(QUrl("local:orders"));
OrderModel2 *model = new OrderModel2;
//wrong Function Overloading
host.enableRemoting(static_cast<QAbstractItemModel*>(model), "OrderModel2");
//should 
bool QRemoteObjectHostBase::enableRemoting(QAbstractItemModel *model, const QString &name, const QList<int> roles, QItemSelectionModel *selectionModel = nullptr)

Oh ! Great ! Smple solution :-)

Since you have it working now, please mark the thread as solved using the "Topic Tools" button or the three dotted menu beside the answer you deem correct so other forum users may know a solution has been found :-)
