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

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

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
