| \title What's New in Qt 5.5 |
| \brief Lists the new features in Qt 5.5. |
| |
| \section1 New Modules |
| |
| \list |
| \li \l[Qt 3D]{Qt 3D} |
| \list |
| \li Included as a technology preview. |
| \li C++ and QML APIs for easy inclusion of 3D graphics into Qt applications. |
| \li Supports OpenGL versions 2, 3 and 4, and OpenGL ES versions 2 and 3. |
| \li Data-driven renderer configuration. |
| \li Extensible beyond 3D graphics. Provides a full Entity Component System framework. |
| \li Supported platforms: |
| \list |
| \li Windows (not RT) |
| \li OS X |
| \li Linux/xcb |
| \li Android |
| \li Embedded Linux with ES 2 |
| \li (Support for QNX and iOS planned) |
| \endlist |
| \endlist |
| \li \l[QtLocation]{Qt Location} |
| \list |
| \li Included as a technology preview. |
| \li Adds mapping, (reverse-)geocoding, routing and place features to Qt. |
| \endlist |
| \endlist |
| |
| \section1 New Features in Qt 5.5 |
| |
| \section2 Qt Bluetooth Module |
| \list |
| \li Classic Bluetooth support added for \l{Qt for macOS}{\macos}. |
| \li Bluetooth Low Energy support added for \l{Qt for Android}{Android}, \l{Qt for iOS}{iOS} |
| and \l{Qt for MacOS}{\macos} |
| \endlist |
| |
| \section2 Qt Core Module |
| \list |
| \li Added a possibility to have Q_PROPERTY and Q_INVOKABLE within a Q_GADGET, |
| with a way to query the QMetaObject of such gadgets using the QMetaType |
| system. |
| \li Added Q_ENUM to replace Q_ENUMS, which allows to get a QMetaEnum at |
| compile time using QMetaEnum::fromType<T>. Such enums are now automatically |
| registered as metatypes, and can be converted to strings within QVariant, |
| or printed as string by qDebug(). |
| \endlist |
| |
| \section2 Qt GUI Module |
| \list |
| \li All Windows packages are now built with \c {-opengl dynamic}. |
| No OpenGL-only or ANGLE-only builds are provided anymore. |
| \li On Windows, the OpenGL implementation to use can now be configured |
| based on the GPU vendor and driver versions using JSON configuration |
| files. This allows shipping fine-grained card and driver blacklists |
| with the applications when necessary. |
| \li QImage: Added 8-bit alpha map and grayscale formats. |
| \endlist |
| |
| \section2 Qt Multimedia Module |
| \list |
| \li Added GStreamer 1.0 support. Note that the default is still 0.10. Version |
| 1.0 support can be enabled by configuring Qt with \c {-gstreamer 1.0}. |
| \li Added a new video filtering framework to integrate frameworks like OpenCV |
| or compute APIs such as OpenCL or CUDA with VideoOutput elements. |
| \li Added a new API to control camera viewfinder settings. |
| \li Improved camera support on iOS (focus, zoom, exposure, image and |
| viewfinder settings). |
| \li The QML MediaPlayer is now rendered in an OpenGL texture on iOS. This |
| means VideoOutput supports advanced transformation and shader effects, |
| and doesn't have to be always on top of other items anymore. |
| \endlist |
| |
| \section2 Qt NFC Module |
| \list |
| \li Ported to \l{Qt for Linux/X11}{Linux} using Neard v0.14 or later. |
| \endlist |
| |
| \section2 Qt Network Module |
| \list |
| \li Added a new SSL backend for iOS and OS X, based on Secure Transport. |
| \li Added support for \e libproxy. |
| \li Added support for TLS PSK ciphersuites. |
| \li Added support for elliptic curve certificates. |
| \li Added ability to select specific curves when using elliptic curve |
| ciphersuites. |
| \endlist |
| |
| \section2 Qt Platform Abstraction (QPA) |
| \list |
| \li Added support for Raspberry Pi 2. |
| \li On supported desktops, the xcb plugin now uses the D-Bus based |
| \c org.kde.StatusNotifier protocol for system tray icons, and |
| \c org.freedesktop.Notifications for notifications. |
| \li Added a KMS/DRM backend for EGLFS. This replaces the now deprecated |
| KMS platform plugin. It allows running applications with eglfs on |
| the console on systems with Mesa and devices that come with DRM |
| support. |
| \li Added a plugin-based backend mechanism for EGLFS, in addition to |
| the existing, statically compiled-in solution. Most compiled-in |
| hooks are converted to be dynamically loaded plugins that are built |
| based on configure time tests. This reduces the reliance on the |
| device makespecs for Raspberry Pi, i.MX6 and Mali-based devices. |
| \li Input handling is now unified for EGLFS and LinuxFB, avoiding the |
| need to launch and configure LinuxFB-based applications differently |
| compared when using EGLFS. |
| \li \e tslib is now better integrated with EGLFS and LinuxFB to provide |
| support for resistive single-touch touchscreens often used in |
| industrial environments. |
| \li xcb is refactored to move GLX and EGL support into plugins. |
| \li Added a TUIO Touch plugin for receiving remote touch events via UDP. |
| \li Added a \e libinput plugin. |
| \li iOS: Added support into QFileDialog for browsing system photos using a |
| native image picker dialog. Selected photos can be loaded using QFile. |
| \endlist |
| |
| \section2 Qt QML Module |
| \list |
| \li Added a possibility to conveniently expose custom C++ value types into |
| the JavaScript environment of QML and QJSEngine. |
| \li Added support for JavaScript typed arrays. |
| \li Various performance improvements, notably QJSValue. |
| \li Added a convenience qJsEngine(QObject*) getter function. |
| \endlist |
| |
| \section2 Qt Quick Module |
| \list |
| \li Windows now defaults to the threaded Qt Quick render loop when using |
| desktop OpenGL (\c opengl32.dll). |
| \li Added support for threaded rendering in QQuickRenderControl. |
| \li Improved behavior of \l [QML] {Flickable} on OS X trackpads using |
| pixel deltas from native gestures. |
| \li Added support for PinchArea to handle native pinch gestures when the |
| OS provides them (so far, only on OS X). |
| \li Added a smart zoom signal to PinchArea to react to that gesture on an |
| OS X trackpad. |
| \li Added a \l {QtQuick::MouseArea::}{scrollGestureEnabled} property to |
| MouseArea to control whether native scroll gestures from the OS will |
| be handled by the wheel signal handler. |
| \endlist |
| |
| \section2 Qt Quick Controls Module |
| \list |
| \li \l [QtQuickExtras]{Qt Quick Extras}, formerly Qt Quick Enterprise |
| Controls, was added under the QtQuick.Extras import. |
| \li Added a TreeView control for QAbstractItemModel-derived models. |
| Supports QItemSelectionModel selection. |
| \endlist |
| |
| \section2 Qt WebEngine Module |
| \list |
| \li Added WebEngineProfile for controlling storage and cache paths and |
| related policies. |
| \li Added support for a JavaScript Geolocation API with \l[QtLocation] |
| {Qt Location} as a backend. |
| \li Added API for managing downloading of files. |
| \li Added API for controlling cache and cookie paths and policy. |
| \li Added API for \WebEngine settings. |
| \li Various experimental QML APIs promoted to public. |
| \li Added QtWebChannel integration API over Chromium IPC. |
| \li Updated Chromium snapshot to version 40. |
| \endlist |
| |
| \section2 Qt WebView Module |
| \list |
| \li Added native implementations for OS X. |
| \li Added API for running JavaScript (Requires API 19+ on Android). |
| \li Added API for setting the HTML content. |
| \li Added API for load status notifications. |
| \endlist |
| |
| \section1 Deprecated Functionality |
| |
| The following modules are deprecated in Qt 5.5: |
| \list |
| \li Qt WebKit |
| \li Qt Declarative (Qt Quick 1) |
| \li Qt Script |
| \endlist |
| |
| These modules are still included in Qt 5.5, but are considered for removal |
| in future releases. |
