## Detailed Description

SwipeView provides a swipe-based navigation model.

SwipeView is populated with a set of pages. One page is visible at a time. The user can navigate between the pages by swiping sideways. Notice that SwipeView itself is entirely non-visual. It is recommended to combine it with PageIndicator, to give the user a visual clue that there are multiple pages.

     SwipeView {
         id: view

         currentIndex: 1
         anchors.fill: parent

         Item {
             id: firstPage
         }
         Item {
             id: secondPage
         }
         Item {
             id: thirdPage
         }
     }

     PageIndicator {
         id: indicator

         count: view.count
         currentIndex: view.currentIndex

         anchors.bottom: view.bottom
         anchors.horizontalCenter: parent.horizontalCenter
     }

As shown above, SwipeView is typically populated with a static set of pages that are defined inline as children of the view. It is also possible to add, insert, move, and remove pages dynamically at run time.

When SwipeView is paired with another container such as TabBar, it is necessary to make a two-way binding between the currentIndex property of each control. To do this without breaking bindings, avoid setting `currentIndex` directly, and instead use setCurrentIndex(), for example. See Managing the Current Index for more information.

To perform an action when `currentIndex` changes, use the `onCurrentIndexChanged` property change signal handler:

     onCurrentIndexChanged: {
         print("currentIndex changed to", currentIndex)
         // ...
     }

It is generally not advisable to add excessive amounts of pages to a SwipeView. However, when the amount of pages grows larger, or individual pages are relatively complex, it may be desirable to free up resources by unloading pages that are outside the immediate reach of the user. The following example presents how to use Loader to keep a maximum of three pages simultaneously instantiated.

     SwipeView {
         Repeater {
             model: 6
             Loader {
                 active: SwipeView.isCurrentItem || SwipeView.isNextItem || SwipeView.isPreviousItem
                 sourceComponent: Text {
                     text: index
                     Component.onCompleted: console.log("created:", index)
                     Component.onDestruction: console.log("destroyed:", index)
                 }
             }
         }
     }

Note: SwipeView takes over the geometry management of items added to the view. Using anchors on the items is not supported, and any `width` or `height` assignment will be overridden by the view. Notice that this only applies to the root of the item. Specifying width and height, or using anchors for its children works as expected.

## Property Documentation

horizontal : bool `[read-only, since QtQuick.Controls 2.3 (Qt 5.10)]`

This property holds whether the swipe view is horizontal.

This property was introduced in QtQuick.Controls 2.3 (Qt 5.10).

See also orientation.

interactive : bool `[since QtQuick.Controls 2.1 (Qt 5.8)]`

This property describes whether the user can interact with the SwipeView. The user cannot swipe a view that is not interactive.

The default value is `true`.

This property was introduced in QtQuick.Controls 2.1 (Qt 5.8).

orientation : enumeration `[since QtQuick.Controls 2.2 (Qt 5.9)]`

This property holds the orientation.

Possible values:

Constant | Description
--- | ---
`Qt.Horizontal` | Horizontal (default)
`Qt.Vertical` | Vertical

This property was introduced in QtQuick.Controls 2.2 (Qt 5.9).

See also horizontal and vertical.

vertical : bool `[read-only, since QtQuick.Controls 2.3 (Qt 5.10)]`

This property holds whether the swipe view is vertical.

This property was introduced in QtQuick.Controls 2.3 (Qt 5.10).

See also orientation.
