findAttachedParent()

static QQuickAttachedPropertyPropagator * findAttachedParent ( const QMetaObject *  ourAttachedType, QObject *  objectWeAreAttachedTo  )

static

Tries to find a QQuickAttachedPropertyPropagator whose type is ourAttachedType and is attached to an ancestor of objectWeAreAttachedTo.

QQuickAttachedPropertyPropagator needs to know who its parent attached object is in order to inherit attached property values from it. This is called when an instance of QQuickAttachedPropertyPropagator is created, and whenever {objectWeAreAttachedTo}'s parent changes, for example.
