| **************************************************************************** |
| * Important Behavior Changes * |
| **************************************************************************** |
| |
| - Control: |
| * Control::hoverEnabled has been made to inherit to children, to make it |
| possible to disable hover effects for a tree of controls in one place. |
| |
| - Tumbler: |
| * Changed the default value of visibleItemCount to 5 to make it visually |
| clearer that it's a Tumbler. |
| * [QTBUG-53587] Changed the default value of wrap to be false when count |
| is less than visibleItemCount. Explicitly setting wrap overrides this |
| behavior. |
| |
| **************************************************************************** |
| * Controls * |
| **************************************************************************** |
| |
| - AbstractButton: |
| * A plain AbstractButton now calculates its implicit size based on the |
| implicit size of the content item plus paddings, and the implicit size |
| of the background item. |
| * [QTBUG-51554] The checkable property has been made accessible from |
| QML. Previously it was only exposed for Button and MenuItem, but it is |
| now available for any AbstractButton to make it possible to create |
| custom QML-based checkable buttons. |
| * [QTBUG-57085] Fixed auto-repeat to not cancel on the tiniest mouse/touch |
| move, but keep repeating until moved outside the button. |
| * Fixed press-and-hold for checkable buttons to not toggle the checked |
| state on release after press-and-hold. |
| |
| - ButtonGroup: |
| * Added clicked(AbstractButton) signal for centralized click handling for |
| grouped buttons. |
| |
| - ComboBox: |
| * [QTBUG-56884] Added handling for Home and End keys. |
| * [QTBUG-56884] Added missing keyboard search functionality. |
| * [QTBUG-54935] Added a flat property that provides more suitable looks |
| for using ComboBox in a ToolBar. |
| |
| - Container: |
| * Added incrementCurrentIndex() and decrementCurrentIndex() methods for |
| changing the current index without losing its property binding. |
| * A plain Container now calculates its implicit size based on the |
| implicit size of the content item plus paddings, and the implicit size |
| of the background item. |
| |
| - Control: |
| * A plain Control now calculates its implicit size based on the implicit |
| size of the content item plus paddings, and the implicit size of the |
| background item. |
| |
| - Dialog: |
| * Added a new Dialog type to provide convenience for handling dialog |
| popups. Dialog integrates with DialogButtonBox, and provides convenient |
| accepted() and rejected() signals. |
| |
| - DialogButtonBox: |
| * Added DialogButtonBox to provide convenience for handling dialog buttons. |
| DialogButtonBox is able to create a set of standard buttons with a single |
| line of QML code, and provides convenient accepted() and rejected() signals. |
| |
| - Drawer: |
| * [QTBUG-55360] Made it possible to control the vertical position of a |
| horizontal drawer, and vice versa. This allows placing a drawer below |
| a header/toolbar, for instance. |
| |
| - MenuSeparator: |
| * [QTBUG-54862] Added MenuSeparator to visually distinguish between groups |
| of items in a menu. |
| |
| - Page: |
| * [QTBUG-56709] Page has been made to calculate its implicit size based |
| on the implicit size of the header, content, and footer plus paddings, |
| and the implicit size of the background item. |
| |
| - Popup: |
| * [QTBUG-56025] Fixed to respect explicitly set width and height. |
| * [QTBUG-56562] The QML Shortcut type from QtQuick has been fixed to |
| respect modal popups from QtQuick Controls 2. |
| * [QTBUG-56755] Fixed binding loops with size-dependent positioning. |
| |
| - RangeSlider: |
| * [QTBUG-50003] Added first.hovered and second.hovered properties that |
| hold whether the respective handles are hovered. |
| |
| - RoundButton: |
| * [QTBUG-54967] Added RoundButton. |
| |
| - Slider: |
| * [QTBUG-53847] Added valueAt() method for converting any position to a |
| value in the slider's range. It is also possible to use valueAt() to get |
| continuous value updates. |
| |
| - SpinBox: |
| * [QTBUG-50003] Added up.hovered and down.hovered properties that hold |
| whether the respective buttons are hovered. |
| * [QTBUG-57085] Fixed auto-repeat to not cancel on the tiniest mouse/touch |
| move, but keep repeating until moved outside the button. |
| |
| - StackView: |
| * Added attached StackView.activated(), StackView.deactivated(), |
| StackView.activating(), and StackView.deactivating() signals that are |
| convenient for initializing and cleaning up item-specific resources. |
| * [QTBUG-55405] Added StackView.removed() attached signal to provide a |
| way to delete items that StackView won't. |
| * Made it possible to choose the visual transition type for any operation. |
| This allows using for example push and pop transitions with replace(), |
| which allows implementing an "infinite" back and forward navigation |
| pattern while keeping the amount of instantiated items constant. |
| |
| - SwipeDelegate: |
| * [QTBUG-54651] Added swipe.close() for setting swipe.position to 0. |
| * [QTBUG-54651] Added swipe.completed() for responding to completion of |
| swipes. |
| * [QTBUG-54651] Added attached SwipeDelegate.pressed property and |
| SwipeDelegate.clicked() signal for detecting when non-interactive |
| left/right/behind items are pressed and clicked. |
| * [QTBUG-56312][QTBUG-57285] Fixed spurious clicked() signal emission when |
| released outside the delegate. |
| * [QTBUG-57271] Fixed swipes that begin over a child item of a delegate. |
| |
| - SwipeView: |
| * Added SwipeView.isNextItem and SwipeView.isPreviousItem attached |
| properties to make it straight-forward to use Loader for unloading |
| pages that are outside the reach. |
| * [QTBUG-54268] Added interactive property for controlling whether swipe |
| interaction is enabled. |
| |
| - TextArea: |
| * [QTBUG-51009] Added pressed() and released() signals. |
| |
| - TextField: |
| * [QTBUG-51009] Added pressed() and released() signals. |
| * Aligned the name of the pressAndHold() argument with TextArea |
| |
| - ToolSeparator: |
| * [QTBUG-54862] Added ToolSeparator to visually distinguish between groups |
| of items in a toolbar by separating them with a line. It can be used in |
| horizontal or vertical toolbars. |
| |
| - Tumbler: |
| * [QTBUG-53587] Added wrap property to control whether or not tumbler |
| wraps when it reaches the top and bottom. |
| |
| **************************************************************************** |
| * Styles * |
| **************************************************************************** |
| |
| - Added support for specifying the fallback style for custom styles via |
| :/qtquickcontrols2.conf, QT_QUICK_CONTROLS_FALLBACK_STYLE or |
| QQuickStyle::setFallbackStyle(). |

| |
| - [QTBUG-50003] Implemented ripple and hover effects. |
| - Fixed (optional) elevation effects for Frame, GroupBox, Pane, and |
| TabBar. |

| system theme colors. |
| |
| Universal |
| --------- |
| |
| - [QTBUG-50003] Implemented hover effects |
| - Added Universal.System theme enum value, that can be used to let the |
