| \title What's New in Qt 5.11 |
| \brief Lists the new features in Qt 5.11. |
| |
| \section1 New Features in Qt 5.11 |
| |
| \section2 Qt Core Module |
| \list |
| \li Added \l{QIODevice::NewOnly} and \l {QIODevice::ExistingOnly} |
| \c OpenMode flags. When used with QFile, \c NewOnly instructs |
| \c open() to (atomically) return \c false if the file to open |
| exists. \c ExistingOnly instructs \c open() to (atomically) return |
| \c false if the file does not exist. |
| \li QFloat16 now has two methods for bulk conversion between \c float16 |
| and \c float, using hardware SIMD acceleration if available at |
| runtime. |
| \li QVarLengthArray now has rvalue reference versions of prepend and |
| insert, and can hold movable-only datatypes such as |
| \c std::unique_ptr. |
| \li QVector now has rvalue reference versions of prepend and insert. |
| \li QUuid \c toString() and \c toByteArray() now take a parameter |
| specifying the generated format. |
| \li Updated Unicode support in QString, QChar, and |
| QTextBoundaryFinder to be compatible with Unicode 10. |
| \endlist |
| |
| \section2 Qt Network Module |
| \list |
| \li ALPN (via Secure Transport) and thus HTTP/2 negotiation are now |
| supported on iOS (starting from version 11). |
| \li QNetworkRequest now has the \c Http2DirectAttribute to start a |
| connection in HTTP/2 without first negotiating. |
| \endlist |
| |
| \section2 Qt QML Module |
| \list |
| \li The compiler pipeline is rewritten. We now directly generate byte code |
| from the AST, and store that as our intermediate representation. |
| \li Optimized handling of JS calls, bringing large improvements |
| especially when calling small functions. |
| \li Newly written byte code interpreter brings significant performance |
| improvements, at 80-90% of the JIT in Qt 5.10. |
| \li \c .qmlc files are now fully platform-independent and store byte |
| code instead of assembly. |
| \li New hotspot JIT that generates optimized assembly for byte code that |
| gets repeatedly executed. |
| \li \c {CONFIG += qtquickcompiler} now also works in the open source version, by |
| embedding the generated byte code at compile time. |
| \endlist |
| |
| \section2 Qt Quick Module |
| \list |
| \li Expanded support for loading compressed textures in Image element. |
| Now supports both \c .ktx and \c .pkm container file formats. |
| \endlist |
| |
| \section2 Qt Quick Controls 2 Module |
| \list |
| \li AbstractButton |
| \list |
| \li Promoted the \l {AbstractButton::}{autoRepeat} |
| property from \l [QML] Button to \c AbstractButton. |
| \li Added \l {AbstractButton::}{autoRepeatDelay} and |
| \l {AbstractButton::}{autoRepeatInterval} |
| properties. |
| \li Added \c pressX and \c pressY properties to expose the press |
| point to QML. |
| \endlist |
| |
| \li ButtonGroup |
| \list |
| \li Added a \c checkState property. It indicates the combined check |
| state of the entire group. |
| \endlist |
| |
| \li CheckBox and CheckDelegate |
| \list |
| \li No longer force tristate to \c true when setting \c checkState |
| to \c Qt.PartiallyChecked. This allows presenting a partially |
| checked state without being interactively tri-state. |
| \li No longer consider partially checked as checked. This fixes |
| check state cycling for a non-tri-state checkbox so that it goes |
| from partially checked to fully checked state. |
| \li Made it possible to implement \c nextCheckState() in QML. |
| \endlist |
| |
| \li ScrollBar and ScrollIndicator |
| \list |
| \li Added \c minimumSize, \c visualSize, and \c visualPosition |
| properties. |
| \endlist |
| |
| \li SpinBox |
| \list |
| \li Added a \c displayText property to allow styles to create a |
| light binding to display the textual value instead of having |
| to call the \c textFromValue() JS-function. |
| \endlist |
| \endlist |
| |
| \section2 Qt 3D Module |
| \list |
| \li Scrub through animations with the \c normalizedTime property of |
| QAbstractClipAnimator. |
| \li Issue arbitrary ray casts in world space or screen space. |
| \li Improved SIMD support. |
| \endlist |
| |
| \section2 Qt Location Module |
| \list |
| \li New Qt.labs.location plugin containing experimental QML types. |
| \endlist |
| |
| \section2 Qt WebEngine Module |
| \list |
| \li Updated to Chromium 65. |
| \li Embedded DevTools without using a port and separate browser. |
| \li Installable cookie filter. |
| \li Quota permissions. |
| \endlist |
| |
| \section2 QDoc Documentation Generator |
| \list |
| \li QDoc now uses libclang for parsing C/C++ code. |
| \endlist |
| |
| \section2 Qt Designer Tool |
| \list |
| \li Added support for ID-based translations. |
| \endlist |
| |
| \section2 Qt GUI Module |
| \list |
| \li On Windows Desktop, the accessibility support was updated and |
| vastly improved. The implementation is now based on Microsoft UI |
| Automation (it was formerly based on Microsoft Active Accessibility). |
| \li The widgets themes available on Windows Desktop were updated to |
| better support High-DPI displays, including fixes for several |
| rendering issues, providing improved appearance and functionality. |
| \li Linux Printing now supports more CUPS options with the advanced tab |
| in QPrintPropertiesDialog, allowing many additional settings |
| (amongst them arbitrary page ranges). |
| \li Updated the Unicode bidirectional text algorithm to be compliant |
| with Unicode 10. |
| \endlist |
| |
| \section2 Qt Widgets Module |
| \list |
| \li Added quick text selection by mouse to QLineEdit. |
| \endlist |
| |
| \section2 Qt Serial Bus Module |
| \list |
| \li Added J2534 Pass-Thru CAN plugin for communication between a |
| computer and a vehicle. |
| \li Added description, serial number and channel to QCanBusDeviceInfo, |
| as far as supported by the various plugins. |
| \li Introduced categorized logging to the CAN bus module which can be |
| enabled by the \e "qt.canbus" and |
| \e "qt.canbus.plugins.<pluginname>" filters. |
| \li QCanBusFrame::isValid() now checks for invalid CAN FD payload |
| lengths. E.g. 24 is a valid CAN FD payload length, but 28 is not. |
| \endlist |
| |
| \section2 Qt Bluetooth Module |
| \list |
| \li Ported Bluetooth Low Energy Central role implementation to BlueZ's |
| DBus LE API (minimum version to enable is BlueZ 5.42). |
| \endlist |
| |
| \section1 New Modules |
| No new modules were added in this version. |
| |
| \section1 Platform Changes |
| \list |
| \li MSVC2013 support removed from the code base. |
| \li Qt \WebEngine now requires MSVC 2017 on Windows. |
| \li QNX 6.6 no longer supported (note: QNX 7 remains fully supported). |
| \li macOS 10.10 no longer supported. |
| \li Improved Accessibility support on Win32 by adopting the Windows UI |
| Automation framework. |
| \li XCB: Support for missing 'dead keys' such as dasia and diaeresis. |
| |
| \li eglfs |
| \list |
| \li Added support for framebuffer formats other than XRGB8888 |
| (RGB565, ARGB8888). |
| \li Added experimental screen cloning support (by scanning out the |
| same framebuffer on multiple displays). |
| \li Added support for operating with DRM render nodes |
| (/dev/dri/renderDnn) in a headless mode transparent to |
| applications. |
| \li Added a makespec for Renesas R-Car M3. |
| \li Added experimental backend for compositing Qt content with other |
| hardware layers via VSP2 on Renesas devices. |
| \endlist |
| \endlist |
| |
| \section1 Technology Preview Modules |
| \list |
| \li Qt Remote Objects (TP3) - A module that allows you to easily share |
| QObject interfaces (Signals/Slots/Properties) between processes or |
| devices. |
| \li Qt WebGL Streaming Plugin (TP2) - Stream applications to browsers |
| over the network. |
| \endlist |
