| \title What's New in Qt 5.9 |
| \brief Lists the new features in Qt 5.9. |
| |
| Qt 5.9 is a long-term support (LTS) release. |
| |
| \section1 New Features in Qt 5.9 |
| |
| \section2 Qt Core Module |
| \list |
| \li Added the \c {qfloat16 f} and \c {qfloat16 &f} overload functions to |
| the QDataStream class for writing a floating point number to the |
| stream and reading it from the stream. |
| \li Made the QProcessEnvironment class available on iOS, tvOS, watchOS, |
| and VxWorks. |
| \li QRegularExpression now requires the PCRE2 library version 10.20, or |
| later. Support for the PCRE1 library was dropped. A copy of PCRE2 |
| is shipped with Qt and will automatically be used on the platforms |
| that lack it. |
| \li Added the QOperatingSystemVersion class to provide convenient |
| access to the operating system and version. |
| \endlist |
| |
| \section2 Qt GUI Module |
| \list |
| \li Made the QPainter class' GL engine functional with core profile |
| OpenGL contexts. |
| \li Added the QImage::reinterpretAsFormat() function to change the image |
| format without changing the data. |
| \li Added support for \e {compute shaders} in QOpenGLShader::ShaderType |
| and QOpenGLShaderProgram also with OpenGL ES 3.1 and newer. |
| \li Enabled stem-darkening and gamma-correction on OpenType fonts on |
| platforms that use FreeType, if supported. |
| \endlist |
| |
| \section2 Qt Multimedia Module |
| Added the following QML properties: |
| \list |
| \li \l{CameraCapture::supportedResolutions} |
| {CameraCapture.supportedResolutions} |
| \li \l{CameraFlash::supportedModes}{CameraFlash.supportedModes} |
| \li \l{MediaPlayer::notifyInterval}{MediaPlayer.notifyInterval} (also |
| for the \l Audio and \l Video types) |
| \li \l{MediaPlayer::loops}{Video.loops} |
| \endlist |
| |
| \section2 Qt Network Module |
| \list |
| \li Added the QNetworkAccessManager::addStrictTransportSecurityHosts() |
| function to support HSTS (HTTP Strict Transport Security) policies. |
| \li Added the QNetworkAccessManager::redirectPolicy() function and the |
| QNetworkRequest::RedirectPolicy enumeration to determine whether the |
| Network Access API should automatically follow a HTTP redirect |
| response. |
| \endlist |
| |
| \section2 Qt QML Module |
| \list |
| \li Added support for ahead-of-time generation of QML type caches. |
| \endlist |
| |
| \section2 Qt Quick Module |
| \list |
| \li Enabled caching OpenGL shader program binaries used by the Qt GUI |
| module (QPainter's GL paint engine) and the Qt Quick scenegraph on |
| disk to improve application-startup and view-initialization times. |
| \li Added an OpenVG backend for Qt Quick. |
| \li Enabled making window-screen associations directly from QML by using |
| \l {Window::screen}{Window.screen} and \l{Qt::application} |
| {Qt.application.screens}. This enables creating multi-screen aware |
| applications for desktop and embedded without involving C++ code. |
| \li Added a way to query information about the font actually used to |
| render a \l [QtQuick] Text type. |
| \li Added an image provider that can share decoded image data and memory |
| between processes. |
| \endlist |
| |
| \section2 Qt Quick Controls 2 Module |
| \list |
| \li Introduced new QML types: \l DelayButton, \l ScrollView. |
| \li Added multi-touch support. |
| \li Made the \l ComboBox type editable. |
| \li Added the \l{Drawer::}{interactive} property for making a \l Drawer |
| type non-interactive and persistent. |
| \li Enabled live value updates (by default) for the \l Slider, |
| \l [QtQuickControls2] RangeSlider, and \l Dial types. |
| \li Added dedicated notification signals for user interaction: |
| AbstractButton::toggled(), Slider::moved(), |
| SpinBox::valueModified(), and so on. |
| \li Enabled incremental discrete scrolling with the \l ScrollBar type. |
| \li Added enabling and disabling the swipe for the \l SwipeDelegate |
| type. In addition, the swipe can now be opened programmatically. |
| \li Added support for the vertical orientation to the |
| \l {SwipeView::orientation}{SwipeView.orientation} property. |
| \endlist |
| |
| \section2 Qt 3D Module |
| \list |
| \li Added rendering Qt Quick 2 scenes to a texture and interacting with |
| them within a 3D world. |
| \li Added a Technical Preview of a new animation subsystem that enables |
| non-blocking, keyframe animations on the threadpool and exporting |
| from animations from Blender. |
| \li Added Physics Based Rendering (PBR) material |
| (\l{Qt3DExtras::}{QMetalRoughMaterial} and |
| \l{Qt3DExtras::}{QTexturedMetalRoughMaterial}) to Qt3DExtras for |
| improved appearance when used with environment maps. |
| \li Added 3D text support to Qt3DExtras. |
| \li Added the LevelOfDetail type to control the representation of an |
| entity based on distance from the observer or size on the screen. It |
| comes with a convenience loader class that loads different QML |
| files. |
| \li Made the Mesh type plugin based. It comes with plugins for the |
| Wavefront OBJ, PLY and FBX formats and makes it easy to add other |
| formats. |
| \li Added distance field based 2D textured text that can be freely |
| rotated but is based on planar geometry. |
| \endlist |
| |
| \section2 Qt Bluetooth Module |
| \list |
| \li Added Classic Bluetooth support for WinRT. |
| \li Added Bluetooth LE Peripheral support for Android. |
| \endlist |
| |
| \section2 Qt Charts Module |
| \list |
| \li Added support for minor grid lines for logarithmic axes. |
| \li Added options for legend marker shapes to QLegend::MarkerShape. |
| \li Added support for adding more than one bar series to a chart. |
| \endlist |
| |
| \section2 Qt Location Module |
| \list |
| \li Added support for rotating and tilting maps. |
| \li Added touch gestures for rotating and tilting maps. |
| \li Improved support for stacking multiple \l Map types. |
| \li Added the MapCopyrightNotice type to flexibly position the |
| copyrights of multiple map elements on top. |
| \li Enabled styling the HTML copyright using CSS. |
| \li Added support for handing the rendering of map items to the plugin. |
| \li Added the \e MapboxGL plugin that is based on the |
| \c mapbox-gl-native mapping engine. |
| \li Added the \l Map::fitViewportToVisibleMapItems() method to only |
| consider visible items when fitting the viewport. |
| \li Added the MapItemGroup type to combine multiple map items in a |
| separate QML file. |
| \li Added the \l{Map::fieldOfView}{Map.fieldOfView} property to control |
| the camera's field of view when the map is tilted. |
| \li Added the MapParameter type to expose and control plugin-specific |
| runtime functionality. |
| \endlist |
| |
| \section2 Qt NFC Module |
| \list |
| \li Enabled using NFC when running as an Android service. |
| \li Added support for communicating with ISO-DEP, NFC-A, NFC-B, NFC-F, |
| and NFC-V tags or smartcards, such as the German eID card, |
| using QNearFieldTarget::sendCommand() on Android. |
| \endlist |
| |
| \section2 Qt SerialBus Module |
| \list |
| \li Added the CAN FD Bitrate Switch (BRS) and Error State Indicator |
| (ESI) flags to QCanBusFrame (QCanBusFrame::hasBitrateSwitch() and |
| QCanBusFrame::hasErrorStateIndicator()). |
