QtQml
|
||||
------
|
||||
New types and properties in this version can be accessed using
|
||||
"import QtQml 2.2".
|
||||
|
||||
- New class QQmlFileSelectors allows applying a QFileSelector to QML assets
|
||||
and types. One is automatically set on QQmlApplicationEngines from now on,
|
||||
plain QQmlEngines must set their own in order to be affected.
|
||||
|
||||
- QML Singletons can now be defined in QML using the "pragma Singleton"
|
||||
directive, combined with a singleton entry in a qmldir file.
|
||||
|
||||
- The Locale type (from Qt.local()) is now available from the QtQml import as
|
||||
well as from the QtQuick import.
|
||||
|
||||
- New qmlProtectModule function for preventing type injection into built-in
|
||||
QML modules.
|
||||
|
||||
- Qt.application gained several new members
|
||||
* enumeration "state" replaces boolean "active", so as to indicate more
|
||||
states than just active/inactive
|
||||
* strings "organization" and "domain" added, exposing those properties
|
||||
from QCoreApplication.
|
||||
|

QtQuick
|
||||
------
|
||||
New types and properties in this version can be accessed using
|
||||
"import QtQuick 2.2".
|
||||
|
||||
- New scene graph renderer should reduce state changes, number of draw calls,
|
||||
CPU->GPU bandwidth and generally improve performance.
|
||||
|
||||
- QTBUG-33993: There is now one render thread per window in QtQuick.
|
||||
|
||||
- Textures in the scene graph can now be entered into an atlas, facilitating
|
||||
in better batching in the renderer. Atlas textures are enabled by passing
|
||||
QQuickWindow::TextureCanUseAtlas to QQuickWindow::createTextureFromImage()
|
||||
|
||||
- New "Animator" types available for running QtQuick animations on the render
|
||||
thread. This allows certain animations to continue when the GUI thread is
|
||||
blocked.
|
||||
|
||||
- Text gained a hoveredLink signal.
|
||||
|
||||
- TextEdit gained an append method for easier programmatic text controls.
|
||||
|
||||
- TextInput gained an editingFinished signal.
|
||||
|
||||
- Drag and DropArea elements now handle drag'n'drop from other applications.
|
||||
|
||||
- Screen type gained a pixelDensity property, deprecating logicalPixelDensity,
|
||||
as logicalPixelDensity is less portable across some mobile platforms.
|
||||
|
||||
- QTBUG-34368: Click signals are no longer propagated to disabled MouseAreas
|
||||
|
||||
- QTBUG-33644: Windows created dynamically now respond appropriately when
|
||||
modality is set.
|
||||
|
||||
- QTBUG-33699: PathView now follows the same pattern as Flickable for
|
||||
grabbing the mouse.
|
||||
|
||||
- QTBUG-32078: qmlClearTypeRegistrations now works when using QtQuick.
|
||||
|
||||
- QTBUG-33112: Setting an items state too early no longer crashes.
|
||||
|
||||
- QTBUG-32920: Dragging a MouseArea nested in a Flickable now works with touch
|
||||
to mouse translation.
|
||||
|
||||
- QTBUG-32513: Crash fix when changing image source repeatedly.
|
||||
|
||||
- QTBUG-32750: Fix over-clipping text on smaller fonts.
