| \title What's New in Qt 5.4 |
| \brief Lists the new features in Qt 5.4. |
| |
| The focus for Qt 5.4 is mainly about improving the stability, performance, |
| and first-time user experience of the product. |
| |
| \section1 New Modules |
| |
| \list |
| \li \l[QtWebChannel]{Qt WebChannel} |
| \li \l[QtWebEngine]{Qt WebEngine} |
| \li \l[QtWebEngineWidgets]{Qt WebEngine Widgets} |
| \li \l[QtPlatformHeaders]{Qt Platform Headers} |
| \endlist |
| |
| \section1 New Supported Platforms |
| |
| \list |
| \li Qt for \WinRT now a supported platform |
| \li Windows Phone 8.1 minimum supported version |
| \endlist |
| |
| \section1 New Features in Qt 5.4 |
| |
| \section2 Qt GUI Module |
| \list |
| \li QOpenGLContext is now able to adopt existing native contexts |
| (EGL, GLX, and so on). This allows interoperability among Qt and other |
| frameworks, such as game engines. |
| \li OpenGL ES 3.0/3.1 support is improved. The header file for the highest |
| usable ES version (gl31.h, gl3.h or gl2.h) is now automatically included by |
| Qt's headers in -opengl es2 builds. Vertex array objects, framebuffer blits |
| and multisampling are now supported via the standard GLES3 functions, where |
| applicable. |
| \li Selecting the dynamic OpenGL implementation on application startup is |
| now available on Windows when configured with _-opengl dynamic_. This allows |
| using either opengl32.dll or ANGLE's OpenGL ES 2.0 implementation in Qt and |
| applications without the need for two separate builds of the binaries. |
| \li QOpenGLWidget: The modern replacement for QGLWidget and the counterpart |
| of QQuickWidget. |
| \li QOpenGLWindow: Convenience class for performing OpenGL drawing onto a |
| QWindow. |
| \li QRasterWindow: Covenience class for performing software-based drawing |
| via QPainter onto a QWindow. |
| \li Support for 10-bit per color channels images. These can be rendered to |
| and from, though internally the raster engine will still use 8-bit per |
| color channel. If used as the internal format of a QOpenGLFramebufferObject, |
| the OpenGL paint engine is able to render in full precision if supported by |
| the OpenGL driver. |
| \li \WinRT: Added support for native file dialogs. |
| \endlist |
| |
| \section2 Qt Core Module |
| \list |
| \li \WinRT: Added support for native settings container (local and roaming). |
| \li QStorageInfo: Class for providing information about currently mounted |
| storage volumes and drives. |
| \li QByteArrayList: Convenience class adding similar extra methods on top |
| of QList<QByteArray> as QStringList does to QList<QString>. |
| \li QTabletEvent: several improvements to the input information: added |
| information about the stylus buttons being pressed, the rotation and |
| tangential pressures now have consistent ranges across platforms, the |
| proximity events now include the type of stylus or other tool in use, and |
| manual tests and debug output are improved for better verification of |
| functionality. |
| \endlist |
| |
| \section2 Qt Widgets Module |
| \list |
| \li Improved scaling of widget styles based on DPI. |
| \endlist |
| |
| \section2 Qt Quick Module |
| \list |
| \li QQuickRenderControl is made public. This API allows efficient rendering |
| of Qt Quick 2 scenes into framebuffer objects. The contents can then be used |
| in arbitrary ways in Qt-based or 3rd party OpenGL renderers. |
| \li Introduced overlay and \e{pull back} headers and footers for ListView. |
| \li Added QQuickFontMetrics, which provides a subset of QFontMetricsF's API. |
| \li Added QQuickTextMetrics, which provides a declarative API for the |
| QFontMetricsF function arguments. |
| \li QQuickWidget is now supported on Android. |
| \endlist |
| |
| \section2 Qt Quick Controls Module |
| \list |
| \li Native \l{Android Style}{Android style} support on Android v3.0 |
| or later. |
| \endlist |
| |
| \section2 Qt Bluetooth Module |
| \list |
| \li Support for Bluez5. |
| \li Tech Preview of Bluetooth Low Energy (client side support only, on |
| Bluez 4 & 5). |
| \endlist |
| |
| \section2 QPA Plugins |
| \list |
| \li The Wayland platform plugin is now part of the release. |
| \li XCB will now support screen with a depth of 30 (10 bit per color |
| channel). |
| \li More font settings are parsed by fontconfig and GTK platform backends. |
| \li More categorized logging is in use so that you can enable it in the |
| standard ways (qtlogging.ini etc.) instead of needing to set obscure |
| environment variables or uncomment #defines. The log also provides more |
| complete information, especially about events. |
| \li Support for integer device pixel ratios larger than one has been added |
| to the XCB plugin. The ratio is controlled by the environment variable |
| \c QT_DEVICE_PIXEL_RATIO. |
| \endlist |
| |
| \section2 Qt WebKit Module |
| \list |
| \li Added support for OpenGL accelerated 2D canvas to |
| \l{Qt WebKit Widgets}. |
| \li The Qt WebKit module is considered \e done. It will be replaced by |
| Qt \WebEngine. This applies to the widgets as well as to the QML API of |
| Qt WebKit. |
| \endlist |
| |
| \section2 Qt Windows Extras Module |
| \list |
| \li Multiple thumbnail images when hovering over an application's taskbar. |
| \endlist |
| |
| \section2 Qt Sensors Module |
| \list |
| \li Windows Phone: Added compass and ambient light sensors. |
| \endlist |
| |
| \section2 Qt SQL Module |
| \list |
| \li Windows Phone: Added support for sqlite. |
| \endlist |
| |
| \section1 Deprecated Features |
| |
| \section2 Qt OpenGL Module |
| \list |
| \li The Qt OpenGL module (which contain classes that start with \e QGL) is |
| now deprecated in favor of the \l{Qt GUI} module (which contains classes |
| that start with \e QOpenGL). QGLWidget can now be replaced by QOpenGLWidget. |
| \endlist |
