Topics for Today● Catching up: Qt 4.7, Mobility 1.1● What’s next: Qt 4.8, Mobility 1.2● What to expect afterwards

3



Qt 4.7 has just been released● Released in September

● First update 4.7.1 last week● Included in MeeGo 1.1

● Also scheduled to be in MeeGo 1.2● Foundation for MeeGo API● Will be on millions of devices next year

4



Qt Quick● Three components to Qt Quick:

● QML – the language based on JavaScript● QtDeclarative – C++ module● Qt Creator 2.1 – editor and designer

● QtDeclarative is in Qt 4.7● Foundation of Nokia’s mobile strategy

5



Qt Quick● Major features:

● Integration with WebKit and mobile API● Declarative language inspired on CSS,

with JavaScript bindings● Easy to use for rapid UI

prototyping and development●

Open Governance

Why● Opening up is not

news● Qt is growing

● Faster than whatwe can grow

● Pool of talentedpeople:

● You

11

What● Decision-making● General roadmap,

schedules, platform

support, ...● Code reviews andacceptance

● Conflict resolution●

QA checks and results● more...

Now moving to implementation phase



What’s driving the roadmap?

How to get most out of HWaccelerated platforms with Qt?

How to make fluid direct

manipulation UIs with Qt?How improve designer & developer collaboration and productivity?

How to leverage mobile context withQt apps and integrate withweb?

Qt Quick Components●

Reusable UI controls and enablers● Perfect for blending differentiated UIs with

platform look and feel● Integration with platform input methods● Initial focus on MeeGo and Symbian

UX, plus one generic style

Qt Quick EnablersGesture AreaHigh Level gestures (Tap, Swipe, Pinch)

Low Level gestures (touch, sensor)

QML Canvas

Inspired by HTML5 CanvasEnable free-form drawing in QML elements

Early research

GestureArea { Pinch {

onStarted : rootWindow.color = "#a3e2ff" onUpdated : gestureText.text = "Pinch: scale = " + gesture.scaleFactor onFinished : rootWindow.reset()

}}



Qt WebKitPerformance

Publish benchmark resultsMulti-process support though WebKit 2

HTML5 and CSS3 compliance

Publish test suites and test resultsAdd more features such as Geolocation,WebGL, web workers, web socketsMost new features for all Qt’s platforms

Touch, gestures and tactile feedbackHaptics for mobile platforms onlyGestures and multipoint-touch on allcapable Qt platforms

17

WebGL on QtWebKit(in progress, not yet released!)





Other Qt current projects●

Threaded OpenGL rendering● Supported on Desktop and Mobile

● Performance improvements in Core● File I/O rewrite● Threading, HTTP engine, Sockets

● C++0x enablers

19



Qt Creator 2.2 and onwards●

Qt Quick Designer ● Qt Quick Components support planned

for 2.2

● QML Observer ● State and property

debugger ● Visual debugger ● Stepping in and out of C++

20



Qt Mobility 1.2●

MeeGo 1.2 as a target● Ensuring backends for MeeGo● Nokia engineers will use MeeGo as their

platform of choice for development● Improving existing modules with

platform-development APIs●

New: Bluetooth, Account API,IM support for Messaging
