  • Simplified Developer Experience with QMLinnovateDynamic UIsQtCreatorCross-platformperformancePrototypingOpenGLTransitions

  • Who are we?Testers @ Nokia, working on MeeGo middleware

  • Why are we here?Great TechnologyIt will make your life easierWe Love it and we want to share it with you

  • WidgetWidgetWidgetWidgetWidget ModelUIs using widgets are,Clearly structured / BulkyStaticEnforce standard platform look and feelVery useful for traditional applicationsWidgetWidget

  • What do we want?Express a UI the way we think about it: components, views, states, transitions, animations and effects.Connect the UI to real data and back-end functionalityEverything should be fast and easyIn fact so easy that also designers can do it (e.g: the sort of people doing Flash, Silverlight and Web)

  • What do we want?A world where developers and designers work directly together on the same projectA world where a UI is determined by its usability and not by limitations of the underlying technology.

  • Meet QMLQML is a new declarative language extension to QtIt maps almost directly to how you should think about a UI: components, views, states, transitions, animations etcThe declarative language itself is simple and intuitive, the rest is javascriptAll the power and freedom of Qt is still available

  • Declarative UI using QMLRectangle {id: pagewidth: 500; height: 200color: lightgrayText {id: helloTexttext: Hello Worldfont.bold: truefont.pointSize: 24}}Hello World

  • Example simple list based menu with features to launch app, preview app and update it.

    Qt CodeQMLGreat App

  • Common QuestionsCommon Components: Currently, many of the standard components like buttons, textboxes etc are missing. But, they are under development.
