Target multiple platforms from a single source

Shorter development time – faster time to market

Reduced maintenance expense

Avoid OS - subgroups in development organization

Enjoy true platform independence

Target a new platform in weeks, not months

Rapidly respond to evolving market requirements

Remain insulated from platform changes

Actively maintained and developed to support all new mainstream OS variants

Focus development efforts towards value-adding innovation

Delivers real, lasting competitive advantage

Increases developer productivity by making C++ programming faster, easier and more intuitive

Qt development tools eliminate common bottlenecks in the development process: GUI Design & Layout - Qt Designer

Translation/Localization - Qt Linguist

Documentation - Qt Assistant

Cross-platform build system – qmake

Delivers true platform freedom Target a new platform in days or weeks, not months or years

One source code base Less maintenance time and expense – multiplying results of

development efforts

Full access to complete source code on all platforms Development teams can adapt and extend Qt to meet their unique

needs, expediting the development process.January 13 MISTRAL CONFIDENTIAL 17

Sandwiching the middleware and multimedia stack between Qt HMI and GStreamer will provide a complete Linux based infotainment system

Will help bring down the time to develop and to market the solution

Key is to ensure that all stacks, middleware and related IPs – are completely OS agnostic.
