B as ic ing redients

Qt 4.6

• Key goals• Enable better User Experience• Performance• Deploy everywhere

4

New in 4.6: New Platforms • Windows 7• Mac OS X 10.6• Symbian • Real-time operating systems: QNX, VxWorks• Maemo 5

Symbian: Today @ 1300 Room B

Maemo: Today @ 1600 Room C

RTOS: Tomorrow @ 1300 Room D

Symbian: Today @ 1300 Room B

Maemo: Today @ 1600 Room C

RTOS: Tomorrow @ 1300 Room D

New in 4.6: States and Transitions • A robust state chart implementation based on

Harel state-charts and SCXML

• Key benefits: – Simplify application semantics – Use states to improve maintainability – Solidify event-driven programming – Write verifiable application logic

6

State Machine Framework

Tomorrow @ 1300Room C

New in 4.6: Animation API • Allow users to create dynamic UIs

• Integrates with States and Transitions

• Key features: – Animate any QObject property

– Combine animations in groups

– Use easing curves

– Synchronized timer for better

CPU utilization

7

Animation Framework

Tomorrow @ 1415Room B

Tomorrow @ 1415Room B

New in 4.6: Graphics Effects • Apply graphical effects to graphics items or

widgets • Add highlight or accentuation to create visually

appealing user interfaces

• Key features: – Apply effects to any paint device – Common effects built in– Extend with your own effects

8

Special FX with Graphics View

Tomorrow @ 1015Room C

New in 4.6: Gestures & Multitouch • Enable interaction with more than one finger

• Combine sequential touch inputs to a ‘gesture’

• Key benefits – Allow users to interact with applications in better ways – Simplify finger-based interaction with UI components – Allowing common basic gestures

…as well as multi-touch gestures – Enable extensibility

Multitouch & Gestures

Tomorrow @ 0900Room C

Qt 4.7: Qt Kinetic project • Allow developers and designers to create flexible

and visually appealing user interfaces using intuitive code or GUI designer

• Key benefits – Declarative UI programming

– Encourages developer-designer collaboration – Faster time-to-market with rapid prototyping – Expressive language – Exposes Qt objects and properties

via JavaScript

Qt Future: Hybrid Development • Combine easily approachable web

technologies with powerful and scalable Qt C++

• Qt already provides rich features – QtWebKit – QtScript – QtXmlPatterns – QtNetwork

Qt Mobility

• The best framework also on mobile devices

• Cross-platform:– Symbian, Maemo, Windows Mobile, Embedded Linux – Desktop platforms (where appropriate)

• APIs under development: – Location, Messaging, Contacts,

System Information, Multimedia, Bearer Management, Sensors...

Future of Qt tools • Qt Creator

– Support for Symbian and Maemo

– C++ code refactoring tools

• Project “Bauhaus” – Graphical design tool for Qt Kinetic project – Targeted towards programmers and designers

• Continuous support for Visual Studio and Eclipse – Not limited to maintenance only
