For more details, refer to the online documentation +included in this distribution. The documentation is also available online: + +http://doc.qt.io/qt-5/index.html + +The Qt version 5.10 series is binary compatible with the 5.9.x series. +Applications compiled for 5.9 will continue to run with 5.10. + +Some of the changes listed in this file include issue tracking numbers +corresponding to tasks in the Qt Bug Tracker: + +https://bugreports.qt.io/ + +Each of these identifiers can be entered in the bug tracker to obtain more +information about a particular change. + +**************************************************************************** +* General * +**************************************************************************** + + - Added the QtQuick.Shapes plugin providing the Shape and ShapePath + types for rendering geometry-based stroked and filled paths. + Various types of Path existed already for defining movement trajectories + in PathView, but now they can be rendered too. + * PathLine, PathQuad, PathCubic, PathArc, PathCurve, and PathSvg + * Fill: solid color, linear, radial or conical gradients + * Stroke: colored and dashed lines + * Uses GL_NV_path_rendering on recent nVidia GPUs + + - Added the Qt.labs.handlers plugin, providing a Tech Preview version + of Pointer Handlers. These are intended as an improved way of handling + gestures and events from pointing devices (mouse, touchpad, and + touchscreen so far; stylus devices are coming in a future release). + Properties acceptedButtons, acceptedModifiers, acceptedDevices, and + acceptedPointerTypes enable scoping their reaction for specific use + cases, but by default, they work equally well with mouse (as applicable) + and touch devices. So far we have four of them available in QML: + * TapHandler is for detecting clicks and taps, double-clicks, + multi-clicks and taps, and long presses. + * DragHandler provides a way of declaring an Item draggable, and also + has properties which can be used for bindings to achieve + less-mainstream use cases. + * PinchHandler can react to a pinch gesture using two or more fingers + (as configured via properties) or to a native pinch gesture from the OS. + Declaring an instance inside an Item is enough to support pinching to + scale, rotate and move that Item; and it also has properties available + for bindings to enable other use cases. + * PointHandler does not directly manipulate an Item, but just provides + information about individual touchpoints or the mouse, for binding + purposes. It is intended mainly for interactive feedback, orthogonal + to whichever Handler or Item currently has the exclusive grab. + Along with this, control over grabbing has gotten more fine-grained: + the grabPermissions property in a Pointer Handler sets rules for how + Pointer Handlers and Items negotiate for the exclusive grab; and some + Pointer Handlers are able to handle some kinds of interaction with a new + type of grab, the passive grab. There are several new logging categories + you can enable to see how event delivery is done, the grab transitions, + and so on. + + As usual with Tech Preview material, we reserve the right to change it + substantially in future releases. + +**************************************************************************** +* Library * +**************************************************************************** + +QmlTest +------- + + - The returned object from TestCase::grabImage now has 'width', 'height', + and 'size' properties for additional verification. In addition, there is + a save() method to be able to persist the grabbed image to disk (for + diagnostics purposes, for example). + +Qt Quick +-------- + + - [QTBUG-58945] Added the properties ShaderEffectSource.samples and + Item.layer.samples to allow requesting MSAA rendering of an item + subtree, without enabling multisampling for the entire scene. + - [QTBUG-59462] Added support for samplerExternalOES sampler type in + ShaderEffect + - [QTBUG-60268] Added Qt.platform.pluginName property. + - [QTBUG-60268] Selecting software as default renderer moved from build + time to run time + - Resizing is done by setSize() in a couple of places, such that + the widthChanged() and heightChanged() are emitted after both + properties are updated. + + - Flickable: + * [QTBUG-38515] Added a boundsMovement property that allows disabling + the default bounce effect and implementing custom edge effects. + + - Item Views: + * [QTBUG-34576] ListView velocities remain correct during index-based + programmatic scrolling + + - Important Behavior Change: + * [QTCREATORBUG-15000] The implicitWidthChanged2 and + implicitHeightChanged2 signals of QQuickImplicitSizeItem have been + removed. Although these were undocumented and hence private API, any + applications currently using them should use the public + implicitWidthChanged and implicitHeightChanged signals. + + - Item: + * Add QQuickItem::size() and document QQuickItem::setSize(). + * When subclassing QQuickItem, you should call setAcceptTouchEvents(true) + if you need the item to receive touch events. It will be required later on. + * Added a ItemEnabledHasChanged value to the ItemChange enum. + QQuickItem::itemChange(ItemEnabledHasChanged) gets called when the + item's effective enabled state has changed. The new enabled state is + stored in ItemChangeData::boolValue. + + - Window: + * It is now possible to set the default render type of text-like + elements globally via the QQuickWindow::setTextRenderType() function. + If you were using the (undocumented) QT_QUICK_DEFAULT_TEXT_RENDER_TYPE + macro when building Qt Quick for the same purpose, note that the macro + value needs now to be set to the "NativeTextRendering" value, instead + of "NativeRendering". + + - Screen: + * Added manufacturer, model and serial number. + + - TextEdit: + * Added tabStopDistance property + + - Text: + * [QTBUG-56728] Added "advance" property to Text element. + * [QTBUG-56728] Added "font.preferShaping" property to Text, TextEdit + and TextInput. This makes it possible to improve performance at the + expense of some cosmetic font features. + * [QTBUG-56728] Added "kerning" property to the font type to support + disabling kerning on text. + * [QTBUG-61984] Fixed an issue when the family of an application font + was hardcoded and applied to text before the font itself was loaded. + + - Image: + * [QTBUG-59872][QTBUG-29451] Allow direct loading of pkm texture files + into Image. For example: Image { source: "myImage.pkm" } + + - QtTest: + * [QTBUG-53381] Added keySequence() function in TestCase. + +QtQml +----- + + - [QTBUG-58493] "const" variable declarations are now available in JS as + well as QML mode. + - [QTBUG-58493] "const" variable declarations now require an initializer, + bringing them closer to the required spec behavior. + - [QTBUG-58493] "const" variable declarations now throw a SyntaxError if + multiple attempts to declare the same variable name are found. Note that + "const" is still not fully spec-compliant (i.e. reassignment at runtime + is not disallowed). + - Object.assign from the ES6 specification is now implemented. + - Number now contains the MAX_SAFE_INTEGER, MIN_SAFE_INTEGER, isInteger + and isSafeInteger properties from the ES6 specification. + - [QTBUG-24799] The instanceof keyword in JavaScript has been extended to + work on QML types and instances. This means that you are now able to use + it to verify that a var is indeed the type you expect (e.g. someVar + instanceof Rectangle). + - [QTBUG-54961] Support C++11 scoped enums in QML. These can now be + accessed as .. + - The QML engine can now emit informational messages (in the + "qt.qml.binding.removal" logging category) whenever a binding is lost + due to an imperative assignment. This can be used to debug issues due to + broken bindings. + - [QTBUG-61599] Allow sending binary data, encoded as ArrayBuffer objects, + via XMLHttpRequest's send() method. + - [QTBUG-14861] Enums can now be declared directly in QML. + - [QTBUG-63464] Fix Number.isNaN() returning incorrect values with some + glibc versions. + - [QTBUG-52515] Qt.platform.os returns "qnx" when running on QNX + platforms. + - [QTBUG-60133] std::vector and QVector are now on par with QList as a + Q_INVOKABLE return type and as a property type + + - QQmlEngine: + * [QTBUG-15602] Added retranslate() slot and QEvent::LanguageChange + support to refresh bindings when changing the language at runtime. + +qmlscene +-------- + - Added --core-profile option to request that type of OpenGL context + - Added --apptype option to set the application class (like the qml + runtime tool already had) -- cgit v1.2.3
