What is Qt?

What is Qt?

High-level C++ application frameworkModules (including a UI toolkit)

Language features

Bought by NokiaUnify mobile development

Cross-platform“write once, run anywhere”

Platform subtleties...

ArchitectureHow did we build it?

Architecture

MVC-inspired:

Model

Controller

View

Architecture

libirail: API wrapperQt C++

Asynchronously (in a pleasant way)

Relatively lightweight

Reusability!

PlatformsWhere can we use Qt?

Maemo

Linux-based mobile platform

Power-user devicesInternet tablets: N800, N810

“Mobile computers”: N900

Why Maemo?Easy to develop for

Afterwards: port to other platforms

Qt through package (shipped by default)

MeeGo

Merge of Maemo and Moblin

Not only phonesNetbook

TV

In-Vehicle computers

Native Qt!

First usable release: 2011/04

Symbian

Open-source phone platform

Smartphones (mid- and high-end)Symbian^1: Series 60

Symbian^3

Not Series 40 (“mobile phones”)

Qt through package (easy to install)

Many devices: UI reimplementation (easy)

Desktop

Possible (libirail)

Not a priority

Future

Future

Maemo: almost finishedPublic beta (2011/02/14-19)
