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.

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.
