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.
Ongoing Changes The dominant UI paradigm is changing from a static mouse, keyboard and keypad paradigm into a more dynamic direct touch manipulation experience Increasing role of UI designers and iterative co-operation between designers and developers Accelerated hardware, especially Open GL and Open GL ES, are becoming ubiquitous Web applications and cloud computing become more common and solve many software deployment problems. Importance of the native OS decreases, which adds fragmentation – e.g. Mac OS X market share is growing. Impact to Qt Qt already well positioned with multi-touch and gestures support, Graphics View canvas, and Qt Quick – however all these areas require further development, and the use cases need to be extended to WebKit Increased focus on Qt Quick and its Visual tooling support, and WebKit Research on new graphics architecture optimized for hardware acceleration Qt’s cross-platform benefits increasingly important for professional applications. WebKit is a key component for server driven Uis.
We focus on the areas that will have a positive impact on Nokia and Ovi in the coming 2-3 years. We move into these segments to pave the way for Ovi, but also to “provide alternative” to Apple and Android platform – M2 opportunity. We will isolate Apple and Android due to their limited openess by doing this right We can’t win in the mkt by just making mobile phone assets happy. Where are there low cost hardware opportunities for Nokia? Where are their services opportunities for Nokia? Multiple competitors in each segment Its got to be hybrid to compete in these markets!

Ideen med bildet er å illustrere litt hvor Qt står i dag. Her ser vi Google earth, vår favoritt applikasjon som kjører på windows Vista. Den er en Qt applikasjon og vi ser dermed at Qt brukes og at det funker.

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

Qt roadmap in brief Up to Qt 4.6 <ul><li>Cross-platform requirement
Developer efficiency and out-of-the-box experience
Active Qt ecosystem and developer network </li></ul>
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
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
Qt Creator – the Qt IDE Cross platform, sophisticated code editing, version control, simulators, visual editors (Qt Designer)
