3 Four Concepts for the Multiscreen World

• Power of C++ • Implement anything. Now.

• QML • Native performance. Custom Look and Feel.

• Hybrid Application development • Deliver the same content, everywhere.

• Interconnectivity • Beauty in the Front. Logic in the Back. Data in the Cloud.

4 Application Development Device Creation - desktop and mobile - HMI’s and applications

Software Development Kits (SDK)

5 Industry Challenges Automotive Today

HUD

Instrument Infotainment cluster system

Mobile:

Android, iOS, Windows Phone, WindowsRT, BlackBerry 10, Sailfish

15 Stable application platform

• Medical • Automotive • In-flight systems

16 Qt Quick / QML

• New HW possibilities require new tools

• Declarative UI creation • Rapid prototyping and device creation • Collaborative Designer-Developer workflow

• Unlock unparalleled graphics performance

17 Qt Quick / QML

• Native Look and Feel • Custom UI design

18 Native & Web Hybrid Development

• Qt WebEngine to the rescue!

• Fully integrated graphics stack • Tap into the best of native performance, and the broad set of HTML5 ecosystem and apps available

19 Practical Example on multiple platforms

Qt graphics underneath the web page OpenGL shaders applied to web contents (colorize + 3D page curl) Actual web contents with Web Engine

Qt graphics overlaying Native Qt UI elements to interact web content with web content

20 Interconnectivity Beauty in the Front. Logic in the back. Data in the Cloud!

• Enginio Data Storage • Qt Managed WebSocket (MWS) • Qt Managed Application Runtime (MAR) • Qt WebChannel

30 Qt Creator New Licensing Option – LGPL v3

• LGPL v3 added as a licensing option to Qt 5.4 • Commercial licensing or community edition with GPL 3, LGPL 2.1 or LGPL 3 • LGPL v3 takes a clear stand to follow the spirit of the LGPL • Clear legal language • No patent retaliation • LGPL allows user’s to modify the application and underlying libraries and run the modified app • For Device Creation, creating completely locked devices is not allowed with LGPL v3 • New add-ons will be brought to Qt under commercial and (only) LGPL v3 licensing options • Allows The Qt Company to unify the ecosystem without business compromises • Qt WebEngine is available only under commercial and LGPL v3 options

33 Summary

• Comprehensive application framework • Rich set of application building blocks • Build advanced user interfaces, faster

• Support multiple platforms – desktop and embedded - from a single source • Boost productivity through integrated tools • Rely on professional service and support

• Keep control of your value chain and monetization
