Introduction to QML

Qt and Qt Quick Platform Overview Qt - Released publicly in 1995 by Trolltech Popular on Embedded platforms & Linux (KDE) 2010 - Nokia Qt SDK v1.0 was released (Qt 4.6) Qt Quick runs QML, introduced with Qt 4.7 - 2011 QML = Qt Meta Language / Qt Modeling Language

import QtQuick 1.0

Rectangle { id: canvas width: 200 height: 200 color: "blue" Image {

id: logo source: "pics/logo.png“anchors.centerIn: parent x: canvas.height / 5

}}

JavaScript CSS GUI Layer for Qt Apps Animations and Transitions Fluid UI Performance

(60FPS) Media APIs Qt Mobility APIs Qt C++ Plugins

Future of Qt Quick More Platforms like QNX, Android, iOS and maybe WP ;) Qt5 (summer 2012)

Powerful and high-performing C++ API QML as the best way to create rich interfaces Qt Quick 2 in Qt5 QML is our bet in "the next step in GUI programming" Should apply for most use-cases Qt Quick 2 uses the Google V8 Javascript Engine

Superfast JS support Architectures: x86, x86-64, ARM

Future of Qt Quick – Continued… Qt Quick 3D QML bindings for Qt3D Access to OpenGL and 3D graphics hardware QML Item3D elements live in 3D space

OpenGL, 3D hardware, and C++ convert this to 2D on screen Desktop support will continue to exist

Qt Quick components for Desktop are ready Qt Webkit in Qt5
