| **************************************************************************** |
| * Qt 5.9.4 Changes * |
| **************************************************************************** |
| |
| QtQml |
| ----- |
| |
| - Added qt.qml.gc.statistics and qt.qml.gc.allocatorStats logging |
| categories for garbage collection statistics |
| - [QTBUG-56521][QTBUG-56532] Added private qmlUnregisterType(int) for |
| advanced use cases such as re-registering an enum, or cleaning up |
| when a plugin is unloaded |
| - [QTBUG-61209] Fixed handling of QML cache files during URL interception. |
| This changes the semantics of URL redirects. Previously a redirected URL |
| was used as the base URL for further URL resolution. This doesn't work |
| because redirection occurs after interception and interception should |
| not influence the resolution of further URLs. We now use the original |
| URL as base URL for resolution of further URLs and rely on the server to |
| redirect those, too. |
| - [QTBUG-63844] Fixed a crash in QMetaObject::activate() when using |
| a Loader to load items with animations |
| |
| QtQuick |
| ------- |
| |
| - QQuickWindow: |
| * Added logging category qt.quick.window.transient to check detection of |
| transient windows declared inside other Items and Windows |
| |
| - QQuickWidget: |
| * [QTBUG-64241] Synthesized mouse events delivered via QQuickWidget |
| have QMouseEvent::source() set so they can be identified as synthesized |
| * [QTBUG-64548] Shortcut now works in QQuickWidget |
| * Fixed coordinate transformation in QInputMethodQueryEvent as delivered |
| to QQuickWidget |
| |
| - Input Handling: |
| * [QTBUG-53036] When an application is deactivated (applicationState() is |
| no longer ApplicationActive), it's treated the same as window deactivation. |
| Thus on mobile devices MouseAreas no longer get stuck in pressed state, etc. |
| * [QTBUG-61144] Fixed the regression that when a mouse-handling Item |
| or Control is used in a Flickable with a pressDelay, the delegate item |
| did not receive touchscreen taps (in the form of mouse clicks) |
| * [QTBUG-63026] Flickable no longer jumps when reversing the direction of |
| scrolling on a pixel-delta-capable trackpad |
| * [QTBUG-64249] When pressing one MouseArea via mouse, then tapping another |
| via touch, then releasing, the first MouseArea correctly gets released |
| |
| - Item Views: |
| * [QTBUG-46488] Refilling is restarted when necessary due to changing |
| the model in a delegate's Component.onCompleted() |
| * [QTBUG-50992] Fixed a bug which caused Qt Quick Controls to often be |
| "destroyed during incubation" during asynchronous creation |
| * [QTBUG-54859] Fixed a crash when items in a Repeater are moved around |
| during asynchronous creation |
| * [QTBUG-61537] Fixed incorrect delegate geometry due to model changes |
| during delegate creation |
| * [QTBUG-62864] Fixed incorrect ListView and GridView highlight position |
| while scrolling through delegates backed by a lazy-loading model |
| * [QTBUG-63743] Fixed a bug with clipping of items in a ScrollView |
| |
| - Other: |
| * [QTBUG-62913] AnimatedImage.frameCount now has a NOTIFY signal |
| * [QTBUG-65156] Fixed a memory leak by releasing textures during resizing |
