I'm running into difficulty retrieving values from a service call that is supposed to return an array of integers. The method call in the interface xml file is defined as:
<method name="PurpleFindBuddies">
<annotation name="org.qtproject.QtDBus.QtTypeName.Out0" value="QList<int>"/>
<arg name="accountId" type="i" direction="in" />
<arg name="screenName" type="s" direction="in" />
<arg name="buddies" type="ai" direction="out" />
</method>
qdbusxml2cpp generates the following method:
inline QDBusPendingReply<QList<int> > PurpleFindBuddies(int accountId, const QString &screenName)
{
QList<QVariant> argumentList;
argumentList << QVariant::fromValue(accountId) << QVariant::fromValue(screenName);
return asyncCallWithArgumentList(QLatin1String("PurpleFindBuddies"), argumentList);
}
I have also added
Q_DECLARE_METATYPE(QList<int>)
at the top of the generated .h file. And in main.cpp, I'm making the following call
QDBusPendingReply<QList<int> > buddies = pidgin->PurpleFindBuddies(accountId, "email@gmail.com");
buddies.waitForFinished();
if ( buddies.isError() ) {
qDebug() << buddies.error();
return -1;
}
qDebug() << buddies.argumentAt(0).toList().size();
When I launch the program, I can see from the enabled debug output that I am getting results, as shown below, but the qDebug() line prints 0. I cannot figure out how to correctly retrieve the results.
QDBusConnectionPrivate(0x138fbc0) got message reply (async): QDBusMessage(type=MethodReturn, service=":1.135", signature="ai", contents=([Argument: ai {859}]) )
What am I missing? Any assistance would be greatly appreciated.
So apparently everything was configured correctly. However, when trying to retrieve the data, instead of doing:
qDebug() << buddies.argumentAt(0).toList().size();
I should have been doing:
qDebug() << QString::number(buddies.value().size());
To retrieve the individual ids
foreach(int id, buddies.value() )
qDebug() << QString::number(id);
// or simply
QList<int> ids = buddies.value();
