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

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
Webkit 2 architecture
