  20. 20. Symbian – Mac / Linux• Symbian binaries cannot be compiled on Mac or Linux * – Legacy Symbian tool chain restriction• Use Remote Compiler instead – Compilation done on Nokia servers in the cloud – Compiler log messages displayed in real-time in Qt Creator – Binaries delivered back to you• Enable Remote Compiler during SDK installation or later using the SDK maintenance tool – Found under the “Experimental” section 27 © 2011 Nokia Qt App Development v. 3.4.6 January 17, 2012 Andreas Jakl * Experimental Linux support for building Symbian apps: http://projects.forum.nokia.com/symbian_linux_qtsdk
  21. 21. Qt SDK: Simulator• Efficient Testing – Quick – Scripting (JavaScript) – Simulate phone events – Battery, messages, etc. – Simulate mobile environment – Location, contacts, etc. – Skins28 © 2011 Nokia Qt App Development v. 3.4.6 January 17, 2012 Andreas Jakl

  23. 23. QWidgets• UI Elements (QLabel, QPushButton, etc.) – Use platform UI design – Support style sheets – Drag & drop UI designer Great for desktop. Static layouts make effects difficult. Small UI, different interaction paradigms.32 © 2011 Nokia Qt App Development v. 3.4.6 January 17, 2012 Andreas Jakl
  24. 24. Graphics View• Manage 2D scenes with a scene graph – Can manage thousands of items with hierarchies – Collision detection, affine transformations, drag and drop support – Hardware acceleration and integration with QWidget possible High level Conceptually nice and flexible No ready-made common UI components available Qt 5 development focus on Qt Quick33 © 2011 Nokia Qt App Development v. 3.4.6 January 17, 2012 Andreas Jakl
  25. 25. Qt Quick• Qt Quick – QML language and JavaScript – Declarative syntax, animations and states – Drag & drop UI designer Very easy to make slick, fluid UIs. Most important for mobile devices! UI components for desktop still experimental35 © 2011 Nokia Qt App Development v. 3.4.6 January 17, 2012 Andreas Jakl * Project page: http://bugreports.qt.nokia.com/browse/QTCOMPONENTS
  26. 26. OpenGL• Very low level – Basic setup provided by Qt Angry Birds and Bounce by Rovio Complete control over GL Good if you have existing codebase & assets, cross-platform OpenGL is hard work (but there’s more Qt coming for that *)36 © 2011 Nokia Qt App Development v. 3.4.6 January 17, 2012 Andreas Jakl * Project page: http://doc.qt.nokia.com/qt-quick3d-snapshot/index.html
  27. 27. QtWebKit• Open source browser engine – Display HTML(5) and JavaScript – Combine Qt QML / C++ and web code if needed to get best of both worlds Use your existing web skills to create the UI Reuse web components (online help, etc.) Complex UIs and interaction probably more difficult Less performance than native code (but improving)37 © 2011 Nokia Qt App Development v. 3.4.6 January 17, 2012 Andreas Jakl

  36. 36. Qt Quick Components• Simplify building rich UIs with Qt Quick – Provides widgets for Qt Quick – Title bar, actions, list items, buttons, etc. – Styles to integrate with native look & feel – MeeGo / Symbian slightly different46 © 2011 Nokia Qt App Development v. 3.4.6 January 17, 2012 Andreas Jakl
