Introduction to Qt cross-platform application and UI framework. Explaining what Qt does, some historical background, hybrid Internet Applications with Qt Webkit and the future with Qt Quick.

1. Qt (cute) Development Frameworks Meet Qt <where> by <your name> – <date>

3. Agenda 1 What, why and how Qt? 2 The future – where Qt is heading with Qt Quick 3 Qt everywhere - Addressable markets

4. Qt history, size and scale • Trolltech founded in 1994 • Trolltech acquired by Nokia in 2008 • More than 250 employees in eight locations worldwide • Trusted by over 5,000 customers worldwide • Used by more than 500,000 commercial and open source developers

5. A park bench in Trondheim, Norway – 1990 “ We need an object-oriented presentation system” - Haavard Nord and Eirik Chambe Eng How the whole thing started

6. Qt overview Qt: a tool for software developers to make the user experience better on different types of platforms • Qt is a powerful and rich application and UI framework for mobile, desktop and embedded platforms. • Using Qt, developers can reuse significant amounts of code when deploying their applications across desktop, mobile and embedded operating systems. For some use cases, Qt allows full cross platform deployment with without any changes to source code. “ Code less. Create more. Deploy everywhere ”

7. Qt is everywhere From embedded devices to mobile and desktop applications Used by leaders from many industries

8. Accelerated Qt growth The Qt SDK - downloads 2008: < 400,000 2010: > 1,500,000 Qt Developer Days 2008: 500 in Munich, 300 in San Fran 2010: 1000+ in Munich, 650 in San Fran 1,6M 2007 2008 2009 2010 0,4M 0,8M 1,2M 2,0M

9. Qt licenses provide flexibility Commercial LGPL v. 2.1 GPL v. 3 License Cost License fee charged No cost No cost Must provide source code for changes to Qt No, modifications can be closed Source code must be provided Source code must be provided Can create proprietary application Yes—no obligation to disclose source code Yes, if dynamically linked to Qt library No, application is subject to the GPL Support Yes, with valid maintenance agreement Not included, available separately Not included, available separately Charge for Runtimes Yes—in some instances* No, distribution is royalty free No, distribution is royalty free * Runtime charges apply when the Qt-based application is part of a joint hardware and software distribution and the main UI of the device is controlled by Qt.

11. Developer efficiency and out-of-the-box experience

12. Short time-to-market

13. Expanded support for embedded and smart phone development

15. Established a new benchmark-driven development culture

16. Increased focus on quality

18. Greater modularity in Qt framework

19. Designer – developer collaboration

20. Continue with quality-driven improvements to existing Qt

21. A new Qt architecture, optimized for direct touch manipulation, Qt Quick, WebKit and accelerated hardware

22. API completeness

23. Responding to market changes © 2010 Nokia From mouse/keypad to direct touch manipulation Accelerated hardware everywhere More iterative co-operation between designers and developers Web applications: solving deployment problems and increasing OS fragmentation

24. Using Qt makes developers happy :)

26. Windows, Mac, Linux, Symbian, MeeGo and more

27. Produce compact, high-performance applications

28. Qt lets you focus on innovation, not infrastructure coding

29. Choice of license – Commercial (via Digia), LGPL or GPL

30. Professional service, support and training

31. Active Qt ecosystem and developer network

32. Open Governance To empower developers using Qt, moving towards a system of Open Governance Open Governance = Nokia Qt developers and external contributors being equal Fair : Treat everyone contributing to Qt – the Qt dev team and external contributors - under the same rules Transparent : Decisions about Qt made in the open Meritocratic : Rights and duties assigned according to merit

33. Qt community and 'The virtuous cycle' Increased use of Qt Larger Qt ecosystem More feedback & contributions Faster pace of innovation = a better Qt Open Source Commercial

34. Qt Creator – the Qt IDE Cross platform, sophisticated code editing, version control, simulators, visual editors (Qt Designer)

35. Qt strength on the desktop Quot from the Hebrew Bible

36. Qt WebKit - Integrate web into your apps

37. Qt Quick: Qt User Interface Creation Kit © 2010 Nokia QML Qt Declarative

38. Challenge between design and implementation The UI design gets lost between idea and realization Designer´s Idea Proof of Concept Realized on Device

39. Qt Quick Fixes the UI design workflow Designer´s Idea Proof of Concept Realized on Device

40. Developers and designers work together! QML Qt C++ Qt Quick Designer

41. What's so Quick about it?

42. Addressable Qt market

43. The mobile consumer – Qt gets you on to more screens ASF - Qt SMS LT 11-24-2009 (piercey)

45. Reuse your code – deploy to multiple platforms

46. Benefit from the large, mature desktop and mobile

47. Qt developer community

48. Use Qt and Qt Quick to innovate and deliver brilliant UI and applications to desktop and embedded

49. Desktop example - Google Earth (Windows, Mac, Linux)

50. 15 years of building better software with Qt > 4460 applications Desktop example - KDE (Linux)

52. + =

53. Community ports take Qt even further* * Qt does not discourage community ports, however these ports, including the community Qt for Android port are not officially supported, or official Qt ports.

55. Create advanced applications. Concentrate on innovation, not basic coding!

56. Broad platform support across desktop mobile and embedded opens up hundreds of millions of devices that can be targeted

57. Community support is a strong part of Qt, and is getting stronger. Everyone contributes by either funding the ongoing development, or contributing code via GPL and LGPL

58. Qt Quick makes rich, quick mobile UIs and applications quicker and easier
