| **************************************************************************** |
| * Important Behavior Changes * |
| **************************************************************************** |
| |
| - Added multi-touch support for buttons and sliders. It is now possible to |
| touch-interact with multiple sliders and buttons at the same time. |
| - By popular demand, Slider, RangeSlider, and Dial have been changed to |
| report live value updates by default. This can be disabled by setting the |
| "live" property to false. |
| - [QTBUG-59920] Sliders and Dials now react immediately when using a |
| mouse. Now the initial drag threshold applies only on touch, to avoid |
| conflicting with flickables. |
| - [QTBUG-58667] ScrollBar now reacts immediately when using a mouse. |
| - [QTBUG-59629] Set explicit cursors on all interactive controls. |
| |
| **************************************************************************** |
| * Controls * |
| **************************************************************************** |
| |
| - AbstractButton: |
| * Added support for multi-touch. |
| * [QTBUG-57203] Added a toggled() signal that is emitted whenever a |
| checkable button is interactively toggled by the user by using either |
| touch, mouse, or keys. |
| |
| - ApplicationWindow: |
| * [QTBUG-58932] The "data" property has been renamed to contentData, as it |
| was documented. Notice that a "data" property still exists in QML |
| Window, but is no longer overshadowed in ApplicationWindow. |
| |
| - Control: |
| * [QTBUG-50992] Resolved the "Object destroyed during incubation" issue |
| that occurred randomly when customizing built-in delegates. |
| |
| - ComboBox: |
| * [QTBUG-53876] Added "editable" property. |
| * Added "down" property. |
| |
| - DelayButton: |
| * Added DelayButton that incorporates a delay before the button becomes |
| activated, to prevent accidental triggers. |
| |
| - Dial: |
| * Added a "live" property that determines whether the dial provides live |
| updates for the "value" property while the handle is dragged. |
| * Added support for wheel handling when wheelEnabled is set to true. |
| * [QTBUG-57203] Added a moved() signal that is emitted whenever the dial |
| is interactively moved by the user by using either touch, mouse, or |
| keys. |
| * Fixed handling of inverted wheel events (natural touchpad scrolling |
| direction on macOS). |
| |
| - Drawer: |
| * [QTBUG-53169] Added "interactive" property that specifies whether the |
| drawer reacts to swipes. This can be used to make drawer a |
| non-closable persistent side-bar. |
| |
| - Menu: |
| * Fixed populating Menus with a Repeater. |
| |
| - Popup: |
| * Allowed passing a Window as a parent when creating dynamic Popup |
| instances using eg. Component.createObject(). Previously, Popup |
| assumed the parent to be an Item, and would complain "cannot find |
| any window to open popup in" if a Window was passed. |
| * [QTBUG-58196] Allowed dynamic window changes after construction. |
| * Fixed the CloseOnRelease close policy for non-modal popups. |
| |
| - RangeSlider: |
| * Added a "live" property that determines whether the range slider |
| provides live updates for the first.value and second.value properties |
| while the respective handle is dragged. |
| |
| - ScrollBar: |
| * [QTBUG-56569] Added snapMode property for incremental or discrete |
| scrolling. |
| * Added an "interactive "property. A non-interactive ScrollBar is visually |
| and behaviorally similar to ScrollIndicator. This property is useful |
| for switching between typical mouse- and touch-orientated UIs with |
| interactive and non- interactive scroll bars, respectively. |
| * Added a "policy" property, which holds whether the scroll bar is shown |
| always/never/as needed (default). |
| |
| - ScrollView: |
| * Added ScrollView. On touch, ScrollView enables flicking and makes |
| the scroll bars non-interactive. When interacted with a mouse device, |
| flicking is disabled and the scroll bars are interactive. |
| |
| - Slider: |
| * Added support for multi-touch. |
| * Added a "live" property that determines whether the slider provides live |
| updates for the "value" property while the handle is dragged. |
| * [QTBUG-57203] Added a moved() signal that is emitted whenever the |
| slider is interactively moved by the user by using either touch, |
| mouse, wheel, or keys. |
| * Fixed handling of inverted wheel events (natural touchpad scrolling |
| direction on macOS). |
| |
| - SpinBox: |
| * [QTBUG-56837] Added inputMethodHints and inputMethodComposing |
| properties for controlling the input method when using editable spin |
| boxes. |
| * [QTBUG-57203] Added a valueModified() signal that is emitted whenever |
| the value of a spin box has been interactively modified by the user by |
| using either touch, mouse, wheel, or keys. |
| * [QTBUG-60356] Forwarded focus to the internal editor of an editable |
| spin box. |
| |
| - StackView: |
| * [QTBUG-56801] Added attached "StackView.visible" property that can be |
| used to control whether items below the top- most item are kept |
| visible. |
| * [QTBUG-57266] Prevented pushing duplicate items. |
| * [QTBUG-59034] Fixed pop/replace exit transition leak, sometimes leading |
| to random crashes since a transition could have been left running in the |
| background at destruction time. |
| * [QTBUG-59098] Prevented StackView filtering mouse ungrab events to avoid |
| MouseAreas being stuck in the pressed state. |
| * [QTBUG-59634] Improved component creation errors by using the standard |
| QML warning system that gives a context/location for the error. |
| |
| - SwipeDelegate: |
| * [QTBUG-57192] Added "swipe.enabled" property to allow disabling of |
| swiping. |
| * Added swipe.open(side) method that can be used to programmatically |
| open the side item on the specified side, which can be either |
| SwipeDelegate.Left or SwipeDelegate.Right. |
| * Added swipe.opened() and swipe.closed() signals, which are emitted |
| when the delegate has been opened or closed by swipe, and the |
| respective transition has finished. |
| * Added a swipe.transition property that holds the transition that is |
| applied when a swipe is released, or swipe.open() or swipe.close() is |
| called. |
| |
| - SwipeView: |
| * [QTBUG-56031] Added "orientation" property. |
| |
| - TabBar: |
| * [QTBUG-57858] Added contentWidth and contentHeight properties that are |
| automatically calculated based on the total size of the tab items, but |
| can be manually overridden if desired. This fixes an issue that TabBar |
| was not able to reliably calculate an implicit size, and could in |
| certain scenarios enter an infinite loop due to a circular dependency |
| between the items' sizes and the tabbar's size. |
| |
| - TextArea: |
| * [QTBUG-55999] Fixed the horizontal alignment of the placeholder text |
| in right-to-left UIs. |
| * TextArea has been made to work inside ScrollView, providing necessary |
| scroll bars out of the box. |
| |
| - TextField: |
| * [QTBUG-55999] Fixed the horizontal alignment of the placeholder text |
| in right-to-left UIs. |
| |
| - Tumbler: |
| * Added a "moving" property that describes whether the tumbler is |
| currently moving, due to the user either dragging or flicking the |
| tumbler. |
| |
| **************************************************************************** |
| * Styles * |
| **************************************************************************** |
| |
| - Added support for a QT_QUICK_CONTROLS_STYLE_PATH environment variable, |
| which can be used to specify lookup paths for Qt Quick Controls 2 |
| styles. This allows device manufacturers and Linux distributions to |
| specify a system-wide style installation folder that may be located |
| outside the Qt installation tree. |
| - Added support for a QT_QUICK_CONTROLS_STYLE_CONF environment variable, |
| which can be used to override the default location of the Qt Quick |
| 2 Controls configuration file (:/qtquickcontrols2.conf). |
| - QQuickStyle: |
| * Added availableStyles() method that returns the list of available |
| built-in styles. |
| |
| Default |
| -------- |
| - Visualized RangeSliders's range. |
| |
| Material |
| -------- |
| - [QTBUG-58797] Fixed cursor visibility for read-only editors. |
| |
| **************************************************************************** |
| * Platform * |
| **************************************************************************** |
| |
| - Menu: |
| * Fixed sub-menu handling when using the Qt Widgets fallbacks on |
| platforms that do not support native menus (Windows, for example). |
