uppercase letter (this has always been the convention). Registration of

type names beginning with lowercase characters is now explicitly disallowed.

|
-------
|
|
|
|
- [QTBUG-50992] Fixed bugs related to deferred property bindings to avoid
|
|
item view delegate objects being destroyed during incubation or failing
|
|
to be created. This fixes a lot of related bugs in QtQuick Controls 2.
|
|
- [QTBUG-64548][QTBUG-62990][QTBUG-64367] Shortcut works in QQuickWidget
|
|
and QQuickRenderControl scenes
|
|
- [QTBUG-65789] An Image with an SVG source uses the SVG renderer to do
|
|
animorphic scaling sharply
|
|
- [QTBUG-64616] Fixed a bug with TextInput validators allowing invalid characters
|
|
- [QTBUG-52944] When a Loader loads a Window, its transient parent will now
|
|
be set to the Loader's window (i.e. the window manager should place it on top).
|
|
- Improved support for compressed textures
|
|
|
|
- Software rendering:
|
|
* [QTBUG-62867] Fixed bad clipping caused by incorrect background coordinates
|
|
|
|
- Item Views:
|
|
* [QTBUG-49218] Fixed an off-by-one layout error in GridView
|
|
* [QTBUG-64311] Fixed the removal transition animation when the last item
|
|
of a GridView or ListView is removed
|
|
|
|
- Shapes:
|
|
* [QTBUG-64951] Some rendering performance improvements; added
|
|
qt.shape.time.sync logging category
|
|
* [QTBUG-65173] Shapes work correctly in static builds
|
|
* [QTBUG-63105] Invisible Shapes can be used with OpacityMask and other
|
|
Qt Graphical Effects
|
|
|
|
- Pointer Handlers:
|
|
* [QTBUG-64692] Pointer Handlers receive events in the reverse of
|
|
declaration order, just as Items receive events in top-down Z order
|
|
* [QTBUG-65003] TapHandler consistently emits the canceled signal when
|
|
its passive or exclusive grab is taken over by another handler or item
|
|
* [QTBUG-64848] One pinch gesture cannot pinch two PinchHandlers at the
|
|
same time; to that end, we now test the target item's bounds correctly
|
|
when delivering native gesture events from trackpads
|
|
* A Pointer Handler with only a passive grab cannot prevent delivery to
|
|
other handlers by accepting all the points in the pointer event.
|
|
This enables Handlers to cooperatively modify behavior of existing controls.
|
|
* TapHandler.gesturePolicy is now DragThreshold by default (rather than
|
|
ReleaseWithinBounds), because this makes it easier for a TapHandler to
|
|
add additional onTapped behavior to existing controls. The reason is
|
|
that the DragThreshold policy only requires a passive grab, not an exclusive
|
|
grab, so it doesn't interfere with the pre-existing event delivery.
|
|
* Fixed a bug with target item translation in DragHandler
|
|
* Added plugins.qmltyles so that syntax highlighting and completion work
|
|
in Qt Creator
|
|
* Various improvements in the tests/manual/pointer manual tests
|
|
|
|
- Platform Specific Changes:
|
|
* [QTBUG-61882][QTBUG-65519] Fixed rendering of emoji on macOS
|
|
* [QTBUG-65663] Fixed re-rendering of window when dragged to a screen
|
|
with a different devicePixelRatio on macOS
