Description
3 Problems:
The second time a remote model is acquired, it doesn't seems to be initialized correctly.
Remote access of the model through proxy doesn't seem to be initialized correctly.
Enabling remote on a model make it loose the specific object user properties (or signal slots, i think)
This is code showing this strange behaviour:
#include <QCoreApplication> #include <QStringListModel> #include <QDebug> #include <QtRemoteObjects/QAbstractItemModelReplica> #include <QtRemoteObjects/QRemoteObjectRegistryHost> void logModel(const QString& message,QAbstractItemModelReplica* model) { qDebug() << "\n" << message << ": \n" << "NbRows:" << model->rowCount() << "\n" << "Available roles:" << model->availableRoles() << "\n" << "First Element:" << model->data(model->index(0,0),Qt::DisplayRole)<< "\n" << "customProperty:" << model->property("customProperty") << "\n"; } int main(int argc, char *argv[]) { // QLoggingCategory::setFilterRules(QStringLiteral("qt.remoteobjects* = true")); QCoreApplication a(argc, argv); QStringList list({"Item1","Item2"}); QStringListModel model(list); QVector<int> roles({Qt::DisplayRole,Qt::EditRole}); model.setProperty("customProperty",1234); QRemoteObjectRegistryHost registry(QUrl(QStringLiteral("local:registry"))); registry.enableRemoting(&model,"model",roles); QRemoteObjectNode nodeInternal; nodeInternal.connectToNode(QUrl(QStringLiteral("local:registry"))); QAbstractItemModelReplica* romodel1 = nodeInternal.acquireModel("model",QtRemoteObjects::PrefetchData,roles); QObject::connect(romodel1,&QAbstractItemModelReplica::initialized,romodel1,[&]() { logModel("Standard Remote initialized",romodel1); QAbstractItemModelReplica* romodel2 = nodeInternal.acquireModel("model",QtRemoteObjects::PrefetchData,roles); if (romodel2->isInitialized()) logModel("Remote copy already initialized",romodel2); }); // New host for proxy QRemoteObjectHost host(QUrl("local:service")); host.proxy(QUrl(QStringLiteral("local:registry"))); QRemoteObjectNode nodeExternal; nodeExternal.connectToNode(QUrl("local:service")); QAbstractItemModelReplica* romodelproxy = nodeExternal.acquireModel("model",QtRemoteObjects::PrefetchData,roles); QObject::connect(romodelproxy,&QAbstractItemModelReplica::initialized,romodelproxy,[=]() { logModel("RemoteModel through proxy",romodelproxy); }); return a.exec(); }
