		const QPointF &	startPos,
		const QVector2D &	activeTranslation,
		qreal	startScale,
		qreal	activeScale,
		qreal	startRotation,
		qreal	activeRotation )

Returns the new position (proposed values for the x and y properties) to which this item should be moved to compensate for the given change in scale from startScale to activeScale and in rotation from startRotation to activeRotation. centroidParentPos is the point that we wish to hold in place (and then apply activeTranslation to), in this item's parent's coordinate system. startPos is this item's position in its parent's coordinate system when the gesture began. activeTranslation is the amount of translation that should be added to the return value, i.e. the displacement by which the centroid is expected to move.

If activeTranslation is (0, 0) the centroid is to be held in place. If activeScale is 1, it means scale is intended to be held constant, the same as startScale. If activeRotation is 0, it means rotation is intended to be held constant, the same as startRotation.

\qmlproperty bool QtQuick::Item::anchors.alignWhenCentered

Anchors provide a way to position an item by specifying its relationship with other items.

Margins apply to top, bottom, left, right, and fill anchors. The \l anchors.margins property can be used to set all of the various margins at once, to the same value. It will not override a specific margin that has been previously set; to clear an explicit margin set its value to undefined. Note that margins are anchor-specific and are not applied if an item does not use anchors.

Offsets apply for horizontal center, vertical center, and baseline anchors.

\table \row

Text anchored to Image, horizontally centered and vertically below, with a margin. \qml Item { Image { id: pic ... } Text { id: label anchors.horizontalCenter: pic.horizontalCenter anchors.top: pic.bottom anchors.topMargin: 5 ... } } \endqml \row
Left of Text anchored to right of Image, with a margin. The y property of both defaults to 0.

\qml Item { Image { id: pic ... } Text { id: label anchors.left: pic.right anchors.leftMargin: 5 ... } } \endqml \endtable

\l anchors.fill provides a convenient way for one item to have the same geometry as another item, and is equivalent to connecting all four directional anchors.

To clear an anchor value, set it to undefined.

\l anchors.alignWhenCentered (default true) forces centered anchors to align to a whole pixel; if the item being centered has an odd \l width or \l height, the item will be positioned on a whole pixel rather than being placed on a half-pixel. This ensures the item is painted crisply. There are cases where this is not desirable, for example when rotating the item jitters may be apparent as the center is rounded.

Note: You can only anchor an item to siblings or a parent.

For more information see \l {anchor-layout}{Anchor Layouts}.

\qmlproperty list<QtObject> QtQuick::Item::data \qmldefault

The data property allows you to freely mix visual children and resources in an item. If you assign a visual item to the data list it becomes a child and if you assign any other object type, it is added as a resource.

So you can write: \qml Item { Text {} Rectangle {} Timer {} } \endqml

instead of: \qml Item { children: [ Text {}, Rectangle {} ] resources: [ Timer {} ] } \endqml

It should not generally be necessary to refer to the data property, as it is the default property for Item and thus all child items are automatically assigned to this property.

◆ deliveryAgent()

QQuickDeliveryAgent * QQuickItemPrivate::deliveryAgent ( )

Returns the delivery agent for the narrowest subscene containing this item, but falls back to QQuickWindowPrivate::deliveryAgent if there are no subscenes.

If this item is not sure whether it's in a subscene (as by default), we need to explore the parents to find out.

If this item is in a subscene, we will find that DA during the exploration, and return it.

If we find the root item without finding a DA, then we know that this item does NOT belong to a subscene, so we remember that by setting maybeHasSubsceneDeliveryAgent to false, so that exploration of the parents can be avoided next time.

In the usual case in normal 2D scenes without subscenes, maybeHasSubsceneDeliveryAgent gets set to false here.

Note: When a Qt Quick scene is shown in the usual way in its own window, subscenes are ignored, and QQuickWindowPrivate::deliveryAgent is used. Subscene delivery agents are used only in QtQuick 3D so far.

Ensures that this item, presumably the root of a subscene (e.g. because it is mapped onto a 3D object in Qt Quick 3D), has a delivery agent to be used when delivering events to the subscene: i.e. when the viewport delivers an event to the subscene, or when the outer delivery agent delivers an update to an item that grabbed during a previous subscene delivery. Creates a new agent if it was not already created, and returns a pointer to the instance.

item	The item that currently has the focus
forward	The direction

Returns: Whether the next item in the focus chain is found or not

If next is true, the next item visited will be in depth-first order relative to item. If next is false, the next item visited will be in reverse depth-first order relative to item.

Deliver the event to all this item's PointerHandlers, but skip HoverHandlers if the event is a QMouseEvent or QWheelEvent (they are visited in QQuickDeliveryAgentPrivate::deliverHoverEventToItem()), and skip handlers that are in QQuickPointerHandlerPrivate::deviceDeliveryTargets(). However if the event is a QTabletEvent, we do NOT skip delivery here: this is the means by which HoverHandler can change the cursor when the tablet stylus hovers over its parent item.

If avoidGrabbers is true, also skip delivery to any handler that is exclusively or passively grabbing any point within event (because delivery to grabbers is handled separately).

◆ localizedTouchEvent()

void QQuickItemPrivate::localizedTouchEvent	(	const QTouchEvent *	event,

Since: 6.0 \qmlproperty Palette QtQuick::Item::palette

This property holds the palette currently set for the item.

This property describes the item's requested palette. The palette is used by the item's style when rendering all controls, and is available as a means to ensure that custom controls can maintain consistency with the native platform's native look and feel. It's common that different platforms, or different styles, define different palettes for an application.

The default palette depends on the system environment. ApplicationWindow maintains a system/theme palette which serves as a default for all controls. There may also be special palette defaults for certain types of controls. You can also set the default palette for controls by either:

\list

passing a custom palette to QGuiApplication::setPalette(), before loading any QML; or
specifying the colors in the \l {Qt Quick Controls 2 Configuration File} {qtquickcontrols2.conf file}. \endlist

Items propagate explicit palette properties from parents to children. If you change a specific property on a items's palette, that property propagates to all of the item's children, overriding any system defaults for that property.

Item {
    palette {
        buttonText: "maroon"
        button: "lavender"
    }
 
    Button {
        text: "Click Me"
    }
}

See also: Window::palette, Popup::palette, ColorGroup, Palette, SystemPalette

Create a modified copy of the given event intended for delivery to this item, containing pointers to only the QEventPoint instances that are relevant to this item, and transforming their positions to this item's coordinate system.

Returns an invalid event with type \l QEvent::None if all points are stationary; or there are no points inside the item; or none of the points were pressed inside, neither the item nor any of its handlers is grabbing any of them, and isFiltering is false.

When isFiltering is true, it is assumed that the item cares about all points which are inside its bounds, because most filtering items need to monitor eventpoint movements until a drag threshold is exceeded or the requirements for a gesture to be recognized are met in some other way.

QQuickItemPrivate::dirty() calls transformChanged(q) to inform this item and all its children that its transform has changed, with transformedItem always being the parent item that caused the change. Override to react, e.g. to call update() if the item needs to re-generate SG nodes based on visible extents. If you override in a subclass, you must also call this (superclass) function and return the value from it.

This function recursively visits all children as long as subtreeTransformChangedEnabled is true, returns true if any of those children still has the ItemObservesViewport flag set, but otherwise turns subtreeTransformChangedEnabled off, if no children are observing.
