Note: This page is work in progress and should not be considered as final list of Qt 5.9 features before the beta release.

New Features (within existing modules)

  • Qt Core
    • Added new qfloat16 class.
    • QProcessEnvironment is now available on iOS, tvOS, watchOS, and VxWorks.
    • QRegularExpression now requires the PCRE2 library, at least version 10.20. Support for the PCRE1 library has been dropped. A copy of PCRE2 is shipped with Qt and will automatically be used on those platforms which lack it.
  • Qt GUI
    • QPainter's GL engine is now functional with core profile OpenGL contexts as well.
    • QImage introduced reinterpretAsFormat to change format without changing data.
    • Compute shaders are now supported in QOpenGLShader and QOpenGLShaderProgram also with OpenGL ES 3.1 and newer.
  • Qt QML
    • Add support for ahead-of-time generation of QML type caches
  • Qt Quick
    • OpenGL shader program binaries used by QtGui (QPainter's GL paint engine) and the Qt Quick scenegraph are now cached on disk, improving application startup and view initialization times.
    • Added an OpenVG backend for Qt Quick.
    • Window-screen associations can now be made directly from QML via Window.screen and Qt.application.screens. This allows creating multi-screen aware applications for desktop and embedded without involving C++ code.
    • Added a way to query information about the font actually used to render a Text element.
  • Qt Quick Controls 2
    • Introduced new QML types: DelayButton, ScrollView
    • Added multi-touch support
    • Editable ComboBox
    • Non-interactive persistent Drawer
    • Live value updates (by default) for Slider, RangeSlider, and Dial
    • Dedicated signals for notifying user interaction
      • AbstractButton::toggled(), Slider::moved(), SpinBox::valueModified(), ...
    • Incremental/discrete scrolling with ScrollBar
    • SwipeDelegate allows enabling/disabling the swipe, and opening programmatically
    • Vertical SwipeView
  • Qt Widgets
  • Qt WebEngine
    • Updated to Chromium 55 or 56
    • Switched internally to the new Chromium build-system GN
    • API for loading with HTTP POST
  • Qt Location
    • Support for map tilting
    • Support for map rotation
    • Touch gestures for rotating and tilting the map
    • Improved support for stacking multiple Map elements
    • New element MapCopyrightNotice to flexibly position the copyrights of multiple map elements on top
    • HTML copyright can now be styled using CSS
    • Support for handing the rendering of map items to the plugin
    • New "MapboxGL" plugin, based on the mapbox-gl-native mapping engine
    • New method fitViewportToVisibleMapItems to only consider visible items when fitting the viewport
    • New element MapItemGroup, to combine multiple map items in a separate qml file
    • Added a field of view property to the Map element to control the camera's field of view when the map is tilted
    • New element MapParameter, to expose and control plugin-specific runtime functionalities
  • Qt Multimedia
  • Qt Network
    • Added HSTS support (HTTP Strict Transport Security) to QNetworkAccessManager
    • Added redirects policy to QNetworkAccessManager (ManulRedirectsPolicy, NoLessSafeRedirectsPolicy, SameOriginRedirectsPolicy, UserVerifiedRedirectsPolicy)
  • Qt WebSockets
    • Added support to handle external QTcpSocket
  • Qt Charts
    • Added support for minor grid lines for logarithmic axes
    • Added options for legend marker shapes
    • Added support for more than one bar series per chart
  • Qt 3D
    • Render Qt Quick 2 scenes to a texture and interact with them within 3D world
    • Technical Preview of new animation subsystem. Non-blocking, keyframe animations on the threadpool. Export from animations from Blender.
    • Physics Based Rendering (PBR) material in Qt3DExtras. Greatly improved appearance when used with environment maps.
    • 3D text support in Qt3DExtras
    • Level of Detail component allows toggling based on projected screen size or distance. Comes with convenience loader class to load different QML files for you.
    • Mesh is now plugin based. Comes with plugins for Wavefront OBJ, PLY and FBX formats. Easy to add others.
    • Distance field based 2D textured text. Can be freely rotated but is based on planar geometry.
  • Qt Virtual Keyboard
    • Added support for selection handles for the dedicated (desktop) keyboard.
    • Changed behavior of shift handler to only activate caps lock if the shift key is double-clicked.
    • Added support for external keyboard layouts, which allows overriding and exclusion of the built-in keyboard layouts.
    • Added language selection popup for faster selection of input language.
    • Added support for automatic selection of the only remaining word in the suggestion list.
    • The word candidate list is now automatically hidden when inactive.
    • Added full screen input mode
  • Embedded platforms
    • Added experimental DRM dumb buffer support to the linuxfb platform plugin, in order to help devices that do not support the deprecated fbdev model (or have problems with fbdev emulation).
    • The evdevtouch plugin supports filtering and prediction of touch events.
  • Qt Bluetooth
    • Classic Bluetooth support for WinRT added
    • Android Peripheral support added

  • Qt Network Authentication (TP2) - Provides support for OAuth1 & OAuth2
  • Qt Speech (TP2) - Continues as tech preview, issues with packaging on Linux were resolved, MinGW not yet supported.
