QT_BEGIN_NAMESPACE QQuickParentAnimation::QQuickParentAnimation | ( | QObject * | parent = nullptr | ) |
\qmltype ParentAnimation \instantiates QQuickParentAnimation \inqmlmodule QtQuick
Animates changes in parent values.
ParentAnimation is used to animate a parent change for an \l Item.
For example, the following ParentChange changes blueRect
to become a child of redRect
when it is clicked. The inclusion of the ParentAnimation, which defines a NumberAnimation to be applied during the transition, ensures the item animates smoothly as it moves to its new parent:
A ParentAnimation can contain any number of animations. These animations will be run in parallel; to run them sequentially, define them within a SequentialAnimation.
In some cases, such as when reparenting between items with clipping enabled, it is useful to animate the parent change via another item that does not have clipping enabled. Such an item can be set using the \l via property.
ParentAnimation is typically used within a \l Transition in conjunction with a ParentChange. When used in this manner, it animates any ParentChange that has occurred during the state change. This can be overridden by setting a specific target item using the \l target property.
Definition at line 55 of file qquickitemanimation.cpp.
QQuickItem * QQuickParentAnimation::newParent | ( | ) | const |
\qmlproperty Item QtQuick::ParentAnimation::newParent The new parent to animate to.
If the ParentAnimation is defined within a \l Transition, this value defaults to the value defined in the end state of the \l Transition.
