◆ QQuickStackView()

QQuickStackView::QQuickStackView ( QQuickItem * parent = nullptr )

explicit

Provides a stack-based navigation model.

\qmltype StackView
\inherits Control

! \instantiates QQuickStackView \inqmlmodule QtQuick.Controls

Since: 5.7

StackView can be used with a set of inter-linked information pages. For example, an email application with separate views to list the latest emails, view a specific email, and list/view the attachments. The email list view is pushed onto the stack as users open an email, and popped out as they choose to go back.

The following snippet demonstrates a simple use case, where the mainView is pushed onto and popped out of the stack on relevant button click:

\qml ApplicationWindow { title: qsTr("Hello World") width: 640 height: 480 visible: true

StackView { id: stack initialItem: mainView anchors.fill: parent }

Component { id: mainView

Row { spacing: 10

Button { text: "Push" onClicked: stack.push(mainView) } Button { text: "Pop" enabled: stack.depth > 1 onClicked: stack.pop()

} Text { text: stack.depth } } } } \endqml

◆ childMouseEventFilter()

bool QQuickStackView::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. If you return true, you should also \l {QEvent::accept()}{accept} or \l {QEvent::ignore()}{ignore} the event, to signal if event propagation should stop or continue. The event will, however, always be sent to all childMouseEventFilters up the parent chain.

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.

◆ pop()

void QQuickStackView::pop ( QQmlV4FunctionPtr args )

\qmlmethod Item QtQuick.Controls::StackView::pop(item, operation)

Pops one or more items off the stack. Returns the last item removed from the stack.

If the item argument is specified, all items down to (but not including) item will be popped. If item is null, all items down to (but not including) the first item is popped. If not specified, only the current item is popped.

Note: A pop() operation on a stack with depth 1 or 0 does nothing. In such cases, the stack can be emptied using the \l clear() method.

pop-ownership

An operation can be optionally specified as the last argument. Supported operations:

\value StackView.Immediate An immediate operation without transitions. \value StackView.PushTransition An operation with push transitions (since QtQuick.Controls 2.1). \value StackView.ReplaceTransition An operation with replace transitions (since QtQuick.Controls 2.1). \value StackView.PopTransition An operation with pop transitions (since QtQuick.Controls 2.1).

If no operation is provided, PopTransition will be used.

Examples:

stackView.pop()
stackView.pop(someItem, StackView.Immediate)
stackView.pop(StackView.Immediate)
stackView.pop(null)

Note: If you are \l {The QML script compiler}{compiling QML}, use the strongly-typed \l popToItem, \l popToIndex or \l popCurrentItem functions instead.

Here is the call graph for this function:

◆ push()

void QQuickStackView::push ( QQmlV4FunctionPtr args )

\qmlmethod Item QtQuick.Controls::StackView::push(item, properties, operation)

Pushes an item onto the stack using an optional operation, and optionally applies a set of properties on the item. The item can be an \l Item, \l Component, or a \l [QML] url. Returns the item that became current.

StackView creates an instance automatically if the pushed item is a \l Component, or a \l [QML] url, and the instance will be destroyed when it is popped off the stack. See \l {Item Ownership} for more information.

The optional properties argument specifies a map of initial property values for the pushed item. For dynamically created items, these values are applied before the creation is finalized. This is more efficient than setting property values after creation, particularly where large sets of property values are defined, and also allows property bindings to be set up (using \l{Qt::binding} {Qt.binding()}) before the item is created.

Pushing a single item:

stackView.push(rect)
 
// or with properties:
stackView.push(rect, {"color": "red"})

Multiple items can be pushed at the same time either by passing them as additional arguments, or as an array. The last item becomes the current item. Each item can be followed by a set of properties to apply.

Passing a variable amount of arguments:

stackView.push(rect1, rect2, rect3)
 
// or with properties:
stackView.push(rect1, {"color": "red"}, rect2, {"color": "green"}, rect3, {"color": "blue"})

Pushing an array of items:

stackView.push([rect1, rect2, rect3])
 
// or with properties:
stackView.push([rect1, {"color": "red"}, rect2, {"color": "green"}, rect3, {"color": "blue"}])

An operation can be optionally specified as the last argument. Supported operations:

\value StackView.Immediate An immediate operation without transitions. \value StackView.PushTransition An operation with push transitions (since QtQuick.Controls 2.1). \value StackView.ReplaceTransition An operation with replace transitions (since QtQuick.Controls 2.1). \value StackView.PopTransition An operation with pop transitions (since QtQuick.Controls 2.1).

If no operation is provided, Immediate will be used if the stack is empty, and PushTransition otherwise.

Note: Items that already exist in the stack are not pushed.; If you are \l {The QML script compiler}{compiling QML}, use the strongly-typed \l pushItem or \l pushItems functions instead.

◆ replace()

void QQuickStackView::replace ( QQmlV4FunctionPtr args )

\qmlmethod Item QtQuick.Controls::StackView::replace(target, item, properties, operation)

Replaces one or more items on the stack with the specified item and optional operation, and optionally applies a set of properties on the item. The item can be an \l Item, \l Component, or a \l [QML] url. Returns the item that became current.

pop-ownership

If the target argument is specified, all items down to the target item will be replaced. If target is null, all items in the stack will be replaced. If not specified, only the top item will be replaced.

StackView creates an instance automatically if the replacing item is a \l Component, or a \l [QML] url. The optional properties argument specifies a map of initial property values for the replacing item. For dynamically created items, these values are applied before the creation is finalized. This is more efficient than setting property values after creation, particularly where large sets of property values are defined, and also allows property bindings to be set up (using \l{Qt::binding} {Qt.binding()}) before the item is created.

Replace the top item:

stackView.replace(rect)
 
// or with properties:
stackView.replace(rect, {"color": "red"})

Multiple items can be replaced at the same time either by passing them as additional arguments, or as an array. Each item can be followed by a set of properties to apply.

Passing a variable amount of arguments:

stackView.replace(rect1, rect2, rect3)
 
// or with properties:
stackView.replace(rect1, {"color": "red"}, rect2, {"color": "green"}, rect3, {"color": "blue"})

Replacing an array of items:

stackView.replace([rect1, rect2, rect3])
 
// or with properties:
stackView.replace([rect1, {"color": "red"}, rect2, {"color": "green"}, rect3, {"color": "blue"}])

An operation can be optionally specified as the last argument. Supported operations:

\value StackView.Immediate An immediate operation without transitions. \value StackView.PushTransition An operation with push transitions (since QtQuick.Controls 2.1). \value StackView.ReplaceTransition An operation with replace transitions (since QtQuick.Controls 2.1). \value StackView.PopTransition An operation with pop transitions (since QtQuick.Controls 2.1).

If no operation is provided, Immediate will be used if the stack is empty, and ReplaceTransition otherwise.

The following example illustrates the use of push and pop transitions with replace().

StackView {
    id: stackView
 
    initialItem: Component {
        id: page
 
        Page {
            Row {
                spacing: 20
                anchors.centerIn: parent
 
                Button {
                    text: "<"
                    onClicked: stackView.replace(page, StackView.PopTransition)
                }
                Button {
                    text: ">"
                    onClicked: stackView.replace(page, StackView.PushTransition)
                }
            }
        }
    }
}
