12 Power of Qt/C++ High level cross platform APIs Interface with other libraries Write and interface with device drivers, communication busses, etc. Modern C++11, C++14, VS2014. clang, etc. Best in class C++ API s Signals and Slots Full Introspection 12

13 Stable application platform Medical Automotive In-flight systems 13

14 QML New HW possibilities require new tools Declarative UI creation Rapid prototyping and device creation Collaborative Designer-Developer workflow Unlock unparalleled graphics performance 14

15 QML Native Look and Feel Custom UI design 15

16 Native and 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 16

25 Extending your Ecosystem 25 25

26 Qt as Technology Platform 26

27 Qt Creator Stable plugin architecture Many interesting customer projects Develop hybrid applications and UI s Emulator that enables desktop and device development on the same machine. 27

28 And where are we headed? Always forwards! New mobile OS es come and go every year. The Desktop and Mobile is seemingly merging Industrial applications look like app store games Continue to drive the state of the art UI development Every screen wants to have the same content and UX as a mobile No one screen size or platform suffers 28

29 Better Life Cycle Management Historically, shipping a Qt application has been a complicated task Goals 1. Simplify dependencies and packaging steps for Qt 5 applications (Framework tasks) 2. Provide wizard / automation tools to further improve workflow (Tooling tasks) Distribution Channel Independent As one potential distribution method the Qt Installer Framework will be integrated into Qt Creator Design Develop Package Distribute 29

30 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 Digia
