\qmltype ViewTransition \nativetype QQuickViewTransitionAttached \inqmlmodule QtQuick
Specifies items under transition in a view.
With ListView and GridView, it is possible to specify transitions that should be applied whenever the items in the view change as a result of modifications to the view's model. They both have the following properties that can be set to the appropriate transitions to be run for various operations:
\list
populate - the transition to apply to the items created initially for the view, or when the model changes add - the transition to apply to items that are added to the view after it has been created remove - the transition to apply to items that are removed from the view move - the transition to apply to items that are moved within the view (i.e. as a result of a move operation in the model) displaced - the generic transition to be applied to any items that are displaced by an add, move or remove operation addDisplaced, removeDisplaced and moveDisplaced - the transitions to be applied when items are displaced by add, move, or remove operations, respectively (these override the generic displaced transition if specified) \endlist
For the \l Row, \l Column, \l Grid and \l Flow positioner types, which operate with collections of child items rather than data models, the following properties are used instead:
\list
populate - the transition to apply to items that have been added to the positioner at the time of its creation add - the transition to apply to items that are added to or reparented to the positioner, or items that have become \l {Item::}{visible} move - the transition to apply to items that have moved within the positioner, including when they are displaced due to the addition or removal of other items, or when items are otherwise rearranged within the positioner, or when items are repositioned due to the resizing of other items in the positioner \endlist
View transitions have access to a ViewTransition attached property that provides details of the items that are under transition and the operation that triggered the transition. Since view transitions are run once per item, these details can be used to customize each transition for each individual item.
The ViewTransition attached property provides the following properties specific to the item to which the transition is applied:
\list
- ViewTransition.item - the item that is under transition
- ViewTransition.index - the index of this item
- ViewTransition.destination - the (x,y) point to which this item is moving for the relevant view operation \endlist
In addition, ViewTransition provides properties specific to the items which are the target of the operation that triggered the transition:
\list
- ViewTransition.targetIndexes - the indexes of the target items
- ViewTransition.targetItems - the target items themselves \endlist
(Note that for the \l Row, \l Column, \l Grid and \l Flow positioner types, the move transition only provides these two additional details when the transition is triggered by the addition of items to a positioner.)
View transitions can be written without referring to any of the attributes listed above. These attributes merely provide extra details that are useful for customising view transitions.
Following is an introduction to view transitions and the ways in which the ViewTransition attached property can be used to augment view transitions.
