The Mobility Project
- 1. The Mobility Project Alex Luddy
- 2. Purpose • Fuel your ideas for using the Qt APIs from the Mobility project 1
- 3. Agenda • Background • Content Overview – Some examples • Questions 2
- 4. Traditional Qt 3
- 5. Qt Going Forward 4
- 6. Mobility Project 5
- 8. Qt Mobility Details • The Mobility project is creating Qt APIs • APIs will have supported functional back-ends on all platforms where it makes sense • Some APIs on Qt labs now 7
- 9. The Story of Bob the Developer • Wants to make a mobile application • Wants the application to be cross-platform • A Web feed reader… 8
- 10. Bearer Management • Enables roaming between connections • Choose most appropriate connection • Manage connections 9
- 11. Bearer Management 10
- 12. Bearer Management Demo 11
- 13. Bearer Management Example class BearerCloud : public QGraphicsScene { // ... QNetworkConfigurationManager manager; }; 12
- 14. Bearer Management Example connect(&manager, SIGNAL(configurationAdded(QNetworkConfiguration)), this, SLOT(configurationAdded(QNetworkConfiguration))); connect(&manager, SIGNAL(configurationUpdated(QNetworkConfiguration)), this, SLOT(configurationUpdated(QNetworkConfiguration))); 13
- 15. Bearer Management Example void BearerCloud::configurationAdded( const QNetworkConfiguration& configuration) { const QNetworkConfiguration::StateFlags state = config.state(); // position in cloud based on state } 14
- 16. Back to Bob • Efficient Internet connection • Web feed reader with contact interest information… 15
- 17. Contacts • Work with contact data • Add custom data • Introspect contact data • Enumerate contact stores – Local and remote 16
- 18. Contacts 17
- 19. Contacts Example: Show Contacts // prepare fetch request QContactManager* manager = new QContactManager(); QContactFetchRequest* fetchRequest = new QContactFetchRequest; fetchRequest->setManager(manager); connect(fetchRequest, SIGNAL(progress(QContactFetchRequest*,bool)), this, SLOT(showContacts(QContactFetchRequest*,bool))); m_fetchRequest->start() 18
- 20. Contacts Example: Show Contacts void Example::showContacts(QContactFetchRequest* request, bool appendOnly) { QList<QContact> results = request->contacts(); // handle append only case // access contacts for display for (int i = 0; i < results.size(); ++i) { QString display = results[i].displayLabel().label(); // ... 19
- 21. Back to Bob • Efficient Internet connection • Access contact details – Add “interest” as custom data • Web feed reader that can send messages to contacts about relevant information.. 20
- 22. Messaging • Send (Email, SMS, MMS) • Work with stored/remote messages • Access message accounts • New message notifications • Retrieve 21
- 23. Messaging 22
- 24. Messaging Example: Send Message // get to address QString to = contact.detail<QContactEmailAddress>().emailAddress(); // prepare message QMessage message; message.setType(QMessage::Email); message.setTo(QMessageAddress(to, QMessageAddress::Email)); message.setSubject(“Boating”); message.setBody(“Here is a link you might like...”); 23
- 25. Messaging Example: Send Message // send QMessageServiceAction service; connect(&service, SIGNAL(stateChanged(QMessageServiceAction::State)), this, SLOT(stateChanged(QMessageServiceAction::State))); service.sendMessage(message); // check send result void MessageSender::stateChanged( QMessageServiceAction::State state) { if (state == QMessageServiceAction::Successful) // all good 24
- 26. Back to Bob • Efficient Internet connection • Access contact details • Send messages to contacts • The “I am going to be late” application… 25
- 27. Location • Where am I? – Stream location data • Be notified when within range of a location • Underlying location technology agnostic 26
- 28. Location 27
- 29. Location Demo 28
- 30. Location Example // create source source = new QNmeaPositionInfoSource( QNmeaPositionInfoSource::SimulationMode, this); // open NMEA data file and set as device for source source->setUpdateInterval(1500); connect(source, SIGNAL(positionUpdated(QGeoPositionInfo)), this, SLOT(positionUpdated(QGeoPositionInfo))); 29
- 31. Location Example void MapWindow::positionUpdated(const QGeoPositionInfo& info) { if (info.hasProperty(QGeoPositionInfo::Heading)) // ... QString url = /* ... */ .arg(QString::number( info.coordinate().latitude())) // ... 30
- 32. Back to Bob • Efficient use of network • Accessing contact details • Sending messages to contacts • Knows where user is 31
- 33. Other APIs for Application Developers • Multimedia • System Information • Calendar (coming next year) • Sensors (coming next year) • More to come… 32
- 34. System Developer APIs • Use case is focused more on development of a system rather than an application • Publish and subscribe • Service framework 33
- 35. Publish and Subscribe • Unifies various sources of hierarchical data into a single consistent model • Uses QVariant /Device/Buttons = 3 /Device/Buttons/1/Name = Context /Device/Buttons/1/Usable = true /Device/Buttons/2/Name = Select 34
- 36. Service Framework • Discover and work with services • Central service registry • XML definition • Out-of-process support coming next year 35
- 37. Service Framework 36
- 38. Content Summary • Bearer Management, Contacts, Messaging, Location, Multimedia, System Information, Publish and Subscribe, Service Framework • … 37
- 39. Summary • Rich cross-platform applications • Qt brilliant developer offering everywhere 38
- 40. Questions • http://labs.qt.nokia.com/page/Projects/QtMobility • All API feedback appreciated 39
