Hi,
Jan is right, you have to use Q_OBJECT to use signals/slots in Qt.
An asynchronous pseudo code based on the example provided in MMQt source
code would look like:
SomeQWidget::someMethod()
{
ModemManager::ModemMessaging::Ptr messaging =
modemdevice->messagingInterface();
ModemManager::ModemMessaging::Message msg;
msg.number = "number";
msg.text = "message text";
QDBusReply<QString> sms = messaging->createMessage(msg);
ModemManager::Sms::Ptr tmp = messaging->findMessage(sms.value());
QDBusPendingReply<> reply = tmp->send();
// This is the important part:
QDBusPendingCallWatcher *watcher = new QDBusPendingCallWatcher(reply, this);
// This only works with Qt5:
connect(watcher, &QDBusPendingCallWatcher::finished, [reply, this]() {
// This code run after the message has been sent.
if (reply.isError()) {
qDebug() << reply.error().message();
}
});
}
