FadeTransition

This QDeclarativeListProperty can contain any QObject. When a QObject is added to property, the UIObject takes ownership of the attached object.

This feature is typically used from QML to specify business logic object or any other shared objects for the subnodes of this UIObject. In C++ the same functionality can be achived by setting a parent of a QObject to be attached to the QObject which is going to own it.

QML usage example (MyObject is a custom class registered for QML using the qmlRegisterType() function):

Container {
    Label { text: "Title: " + myObject.title } 
    Label { text: "Subject: " + myObject.subject }
    attachedObjects: [
        MyObject { id: myObject
            title: "Hello World"
            subject: "Nice Day"
        }
    ]
}

Once an animation is playing, changing its properties will not take effect until the next time animation is started.

The default delay is 0.

The value of this property must be non-negative. A duration of 0 milliseconds means the transition is instantaneous.

If the duration is 0, the value of AbstractAnimation::repeatCount is ignored (it is treated if it was 1).

If the animation was playing when this property is set the change will not take effect until the next time the animation is started.

The default value of this property is 300 milliseconds.

If the animation was playing when this property is set the change will not take effect until the next time the animation is started.

The default value of this attribute is StockCurve::CubicIn

As the objectName property is overridden from the QObject class, this signal will not be emitted if setObjectName() function is called directly on QObject.

The default value of this property is QString::null.

The parent of an object is specified using QObject::setParent(QObject*). The purpose of the property is to expose the object's parent to QML.

This property is read-only to prevent modifications from QML, where typically the parent is declaratively set. In C++ code, the parent can be explicitly set using QObject::setParent(QObject*), or implicitly set by adding it to a visual container.

The default value of this property is 0.

Once an animation is playing, changing its properties will not take effect until the next time animation is started.

To have an animation run forever, you can specify AnimationRepeatCount::Forever. Here's how you can set an animation to run forever in QML:

Container {
    background: Color.Black
    preferredHeight: 50
    preferredWidth: 50
    animations: [
        TranslateTransition {
            id: foreverandever
            fromX: 0
            toX: 500
            duration: 1000
            repeatCount: AnimationRepeatCount.Forever
        }
    ]
    onCreationCompleted: foreverandever.play()
}

The default value is bb::cascades:AnimationState::Stopped.

Even if a target is not explicitly set, the animation can have an implicit target in the following instances:

If an animation has children, setting the explicit target for the animation causes the children's implicit targets to change accordingly.

When the target node is explicitly set on the animation, the node it is attached to does not take ownership, meaning that if the target node is destroyed, the animation is not removed with it. To help manage the animation lifecycle, the ownership of an animation can assigned to a VisualNode by calling VisualNode::addAnimation(). This can help ensure that the animation's memory is cleaned up properly.

Once an animation is playing, changing its properties will not take effect until the next time animation is started.

The default value of this property is 0.
