◆ QQuickPathView()

QQuickPathView::QQuickPathView ( QQuickItem * parent = nullptr )

\qmltype PathView
\instantiates QQuickPathView
\inqmlmodule QtQuick
\ingroup qtquick-paths
\ingroup qtquick-views
\inherits Item
\brief Lays out model-provided items on a path.

A PathView displays data from models created from built-in QML types like ListModel
and XmlListModel, or custom model classes defined in C++ that inherit from
QAbstractListModel.

The view has a \l model, which defines the data to be displayed, and
a \l delegate, which defines how the data should be displayed.
The \l delegate is instantiated for each item on the \l path.
The items may be flicked to move them along the path.

For example, if there is a simple list model defined in a file \c ContactModel.qml like this:

\snippet qml/pathview/ContactModel.qml 0

This data can be represented as a PathView, like this:

\snippet qml/pathview/pathview.qml 0

\image pathview.gif

(Note the above example uses PathAttribute to scale and modify the
opacity of the items as they rotate. This additional code can be seen in the
PathAttribute documentation.)

PathView does not automatically handle keyboard navigation.  This is because
the keys to use for navigation will depend upon the shape of the path.  Navigation
can be added quite simply by setting \c focus to \c true and calling
\l decrementCurrentIndex() or \l incrementCurrentIndex(), for example to navigate
using the left and right arrow keys:

\qml
PathView {

... focus: true Keys.onLeftPressed: decrementCurrentIndex() Keys.onRightPressed: incrementCurrentIndex() } \endqml

The path view itself is a focus scope (see \l{Keyboard Focus in Qt Quick} for more details).

Delegates are instantiated as needed and may be destroyed at any time. State should never be stored in a delegate.

PathView attaches a number of properties to the root item of the delegate, for example {PathView.isCurrentItem}. In the following example, the root delegate item can access this attached property directly as PathView.isCurrentItem, while the child nameText object must refer to this property as wrapper.PathView.isCurrentItem.

    Component {
        id: delegate
        Column {
            id: wrapper
            opacity: PathView.isCurrentItem ? 1 : 0.5
            Image {
                anchors.horizontalCenter: nameText.horizontalCenter
                width: 64; height: 64
                source: icon
            }
            Text {
                id: nameText
                text: name
                font.pointSize: 16
            }
        }
    }

Note that views do not enable clip automatically. If the view is not clipped by another item or the screen, it will be necessary to set {clip: true} in order to have the out of view items clipped nicely.

Member Function Documentation

◆ cacheItemCount()

int QQuickPathView::cacheItemCount ( ) const

\qmlproperty int QtQuick::PathView::cacheItemCount This property holds the maximum number of items to cache off the path.

For example, a PathView with a model containing 20 items, a pathItemCount of 10, and an cacheItemCount of 4 will create up to 14 items, with 10 visible on the path and 4 invisible cached items.

The cached delegates are created asynchronously, allowing creation to occur across multiple frames and reducing the likelihood of skipping frames.

Note: Setting this property is not a replacement for creating efficient delegates. It can improve the smoothness of scrolling behavior at the expense of additional memory usage. The fewer objects and bindings in a delegate, the faster a view can be scrolled. It is important to realize that setting cacheItemCount will only postpone issues caused by slow-loading delegates, it is not a solution for this scenario.

◆ childMouseEventFilter()

bool QQuickPathView::childMouseEventFilter	(	QQuickItem *	item,
		QEvent *	event
	)

overrideprotectedvirtual

Reimplement this method to filter the pointer events that are received by this item's children.

This method will only be called if filtersChildMouseEvents() is true.

Return true if the specified event should not be passed on to the specified child item, and false otherwise.

Note: Despite the name, this function filters all QPointerEvent instances during delivery to all children (typically mouse, touch, and tablet events). When overriding this function in a subclass, we suggest writing generic event-handling code using only the accessors found in QPointerEvent. Alternatively you can switch on event->type() and/or event->device()->type() to handle different event types in different ways.; Filtering is just one way to share responsibility in case of gestural ambiguity (for example on press, you don't know whether the user will tap or drag). Another way is to call QPointerEvent::addPassiveGrabber() on press, so as to non-exclusively monitor the progress of the QEventPoint. In either case, the item or pointer handler that is monitoring can steal the exclusive grab later on, when it becomes clear that the gesture fits the pattern that it is expecting.

◆ delegate()

QQmlComponent * QQuickPathView::delegate ( ) const

\qmlsignal QtQuick::PathView::movementStarted()

This signal is emitted when the view begins moving due to user interaction.

\qmlsignal QtQuick::PathView::movementEnded()

This signal is emitted when the view stops moving due to user interaction. If a flick was generated, this signal will be emitted once the flick stops. If a flick was not generated, this signal will be emitted when the user stops dragging - i.e. a mouse or touch release.

\qmlsignal QtQuick::PathView::flickStarted()

This signal is emitted when the view is flicked. A flick starts from the point that the mouse or touch is released, while still in motion.

\qmlsignal QtQuick::PathView::flickEnded()

This signal is emitted when the view stops moving due to a flick.

\qmlsignal QtQuick::PathView::dragStarted()

This signal is emitted when the view starts to be dragged due to user interaction.

\qmlsignal QtQuick::PathView::dragEnded()

This signal is emitted when the user stops dragging the view.

If the velocity of the drag is suffient at the time the touch/mouse button is released then a flick will start.

\qmlproperty Component QtQuick::PathView::delegate

The delegate provides a template defining each item instantiated by the view. The index is exposed as an accessible index property. Properties of the model are also available depending upon the type of \l {qml-data-models}{Data Model}.

The number of objects and bindings in the delegate has a direct effect on the flicking performance of the view when pathItemCount is specified. If at all possible, place functionality that is not needed for the normal display of the delegate in a \l Loader which can load additional components when needed.

Note that the PathView will layout the items based on the size of the root item in the delegate.

Here is an example delegate:

    Component {
        id: delegate
        Column {
            id: wrapper
            opacity: PathView.isCurrentItem ? 1 : 0.5
            Image {
                anchors.horizontalCenter: nameText.horizontalCenter
                width: 64; height: 64
                source: icon
            }
            Text {
                id: nameText
                text: name
                font.pointSize: 16

so as to stay with the current item.

The below example demonstrates how to make a simple highlight.  Note the use
of the \l{PathView::onPath}{PathView.onPath} attached property to ensure that
the highlight is hidden when flicked away from the path.

\qmlmethod QtQuick::PathView::positionViewAtIndex(int index, PositionMode mode)

Positions the view such that the index is at the position specified by mode:

\value PathView.Beginning position item at the beginning of the path. \value PathView.Center position item in the center of the path. \value PathView.End position item at the end of the path. \value PathView.Contain ensure the item is positioned on the path. \value PathView.SnapPosition position the item at \l preferredHighlightBegin. This mode is only valid if \l highlightRangeMode is StrictlyEnforceRange or snapping is enabled via \l snapMode.

Note: methods should only be called after the Component has completed. To position the view at startup, this method should be called by Component.onCompleted. For example, to position the view at the end:

Component.onCompleted: positionViewAtIndex(count - 1, PathView.End)

◆ preferredHighlightBegin()

qreal QQuickPathView::preferredHighlightBegin ( ) const

\qmlproperty real QtQuick::PathView::preferredHighlightBegin \qmlproperty real QtQuick::PathView::preferredHighlightEnd \qmlproperty enumeration QtQuick::PathView::highlightRangeMode

These properties set the preferred range of the highlight (current item) within the view. The preferred values must be in the range from 0 to 1.

Valid values for highlightRangeMode are:

\value PathView.NoHighlightRange no range is applied: the highlight will move freely within the view. \value PathView.ApplyRange the view will attempt to maintain the highlight within the range, however the highlight can move outside of the range at the ends of the path or due to a mouse interaction. \value PathView.StrictlyEnforceRange the highlight will never move outside of the range. This means that the current item will change if a keyboard or mouse action would cause the highlight to move outside of the range.

The default value is PathView.StrictlyEnforceRange.

Defining a highlight range is the correct way to influence where the current item ends up when the view moves. For example, if you want the currently selected item to be in the middle of the path, then set the highlight range to be 0.5,0.5 and highlightRangeMode to PathView.StrictlyEnforceRange. Then, when the path scrolls, the currently selected item will be the item at that position. This also applies to when the currently selected item changes - it will scroll to within the preferred highlight range. Furthermore, the behaviour of the current item index will occur whether or not a highlight exists.

Note: A valid range requires preferredHighlightEnd to be greater than or equal to preferredHighlightBegin.

This property determines how the items will settle following a drag or flick. The possible values are:

\value PathView.NoSnap (default) the items stop anywhere along the path. \value PathView.SnapToItem the items settle with an item aligned with the \l preferredHighlightBegin. \value PathView.SnapOneItem the items settle no more than one item away from the item nearest \l preferredHighlightBegin at the time the press is released. This mode is particularly useful for moving one page at a time.

snapMode does not affect the \l currentIndex. To update the \l currentIndex as the view is moved, set \l highlightRangeMode to PathView.StrictlyEnforceRange (default for PathView).
