It is used together with \l Rotation, \l State - and \l Transition elements to produce a flipping effect. - - The \l front and \l back properties are used to hold the items that are - shown respectively on the front and back sides of the flipable item. - - \section1 Example Usage - - The following example shows a Flipable item that flips whenever it is - clicked, rotating about the y-axis. - - This flipable item has a \c flipped boolean property that is toggled - whenever the MouseArea within the flipable is clicked. When - \c flipped is true, the item changes to the "back" state; in this - state, the \c angle of the \l Rotation item is changed to 180 - degrees to produce the flipping effect. When \c flipped is false, the - item reverts to the default state, in which the \c angle value is 0. - - \snippet doc/src/snippets/qtquick1/flipable/flipable.qml 0 - - \image flipable.gif - - The \l Transition creates the animation that changes the angle over - four seconds. When the item changes between its "back" and - default states, the NumberAnimation animates the angle between - its old and new values. - - See \l {QML States} for details on state changes and the default - state, and \l {QML Animation and Transitions} for more information on how - animations work within transitions. - - \sa {declarative/ui-components/flipable}{Flipable example} -*/ - -QDeclarative1Flipable::QDeclarative1Flipable(QDeclarativeItem *parent) -: QDeclarativeItem(*(new QDeclarative1FlipablePrivate), parent) -{ -} - -QDeclarative1Flipable::~QDeclarative1Flipable() -{ -} - -/*! - \qmlproperty Item QtQuick1::Flipable::front - \qmlproperty Item QtQuick1::Flipable::back - - The front and back sides of the flipable. -*/ - -QGraphicsObject *QDeclarative1Flipable::front() -{ - Q_D(const QDeclarative1Flipable); - return d->front; -} - -void QDeclarative1Flipable::setFront(QGraphicsObject *front) -{ - Q_D(QDeclarative1Flipable); - if (d->front) { - qmlInfo(this) << tr("front is a write-once property"); - return; - } - d->front = front; - d->front->setParentItem(this); - if (Back == d->current) - d->front->setOpacity(0.); - emit frontChanged(); -} - -QGraphicsObject *QDeclarative1Flipable::back() -{ - Q_D(const QDeclarative1Flipable); - return d->back; -} - -void QDeclarative1Flipable::setBack(QGraphicsObject *back) -{ - Q_D(QDeclarative1Flipable); - if (d->back) { - qmlInfo(this) << tr("back is a write-once property"); - return; - } - d->back = back; - d->back->setParentItem(this); - if (Front == d->current) - d->back->setOpacity(0.); - connect(back, SIGNAL(widthChanged()), - this, SLOT(retransformBack())); - connect(back, SIGNAL(heightChanged()), - this, SLOT(retransformBack())); - emit backChanged(); -} - -void QDeclarative1Flipable::retransformBack() -{ - Q_D(QDeclarative1Flipable); - if (d->current == QDeclarative1Flipable::Back && d->back) - d->setBackTransform(); -} - -/*! - \qmlproperty enumeration QtQuick1::Flipable::side - - The side of the Flipable currently visible.
