| **************************************************************************** |
| * Important Behavior Changes * |
| **************************************************************************** |
| |
| QtQml |
| ----- |
| |
| * [QTBUG-44934] Assigning a char to a string will now create a string |
| with the actual character instead of a string representation of the |
| character's code-point. A side effect of this change is that a |
| one-character string also can be assigned to a character type. |
| |
| QtQuick |
| ------- |
| |
| * Flickable.DragAndOvershootBounds value changed from 2 to 3. This will |
| only affect you if you've worked around enum type checking and have |
| the integer value explicitly in your code. |
| |
| |
| **************************************************************************** |
| * Library * |
| **************************************************************************** |
| |
| |
| Android |
| ------- |
| |
| - [QTBUG-43515] Fixed a vertex shader compilation issue on certain OpenGL |
| drivers. |
| |
| QtQml |
| ----- |
| |
| - [QTBUG-29769] Custom C++ value types annotated with Q_GADGET are now |
| fully accessible in the QML and QJSEngine JavaScript environment. |
| |
| - Added qjsEngine(QObject*) getter similar to qmlEngine(object) that |
| allows retrieving the engine for an exposed object. |
| |
| - Added Qt.hsva() function |
| |
| - XMLHttpRequest: |
| * [QTBUG-35892] XMLHttpRequest now supports the OPTION method in |
| HTTP requests. |
| * QQmlXMLHttpRequest now supports "arraybuffer" binary response type. |
| * Support for synchronous requests |
| |
| QtQuick |
| ------- |
| |
| - BorderImage: Add support for @2x HiDPI border images. This means, no more need to |
| multiply the border sizes by the device pixel ratio. |
| |
| - [QTBUG-37946] Image: An autoTransform property has been added to control |
| whether metadata image transforms such as EXIF orientation are |
| automatically applied. By default it enabled for TIFF images and |
| disabled for JPEG. |
| |
| - Changed to use the threaded render loop by default on Windows when |
| running with desktop OpenGL (opengl32.dll). |
| - [QTBUG-42813] QQuickRenderControl can now be used to render the Qt Quick |
| scene on a dedicated render thread, similarly to how the built-in |
| threaded render loop operates. |
| - Added Window.width and Window.height attached properties |
| - Added a Shortcut utility type for catching keyboard shortcuts |
| |
| - Flickable: |
| * Introduced Flickable.OvershootBounds behavior that allows content |
| overshooting the boundary when flicked, but does not allow dragging |
| content beyond the boundary of Flickable. |
| * [QTBUG-22407] Flickable handles pixel deltas from trackpad gestures as |
| drags, for a more native feel |
| |
| - PinchArea: |
| * Pinch gestures are recognized by the operating system on OSX |
| * Fix infinite recursion when TouchCancel events are received. |
| |
| - TextInput: |
| * SetFocusOnTouchRelease is honored |
| |
| - [QTBUG-44743] Text: Fixed assert when setting an invalid width or height on an |
| <img> tag in a text element. |
| |
| - TextEdit: |
| * [QTBUG-44492] Fixed positioning of text decoration with some fonts. |
| * [QTBUG-45032] Fixed issues with using other vertical alignments than |
| AlignTop. |
