GraphicsObjectContainer helps provide these - functions to other QGraphicsObjects, so that they can be used unaltered in - a QML scene. QGraphicsObjects, which are not QDeclarativeItems, and which are - placed in a QML scene outside of a GraphicsObjectContainer, will not appear - on screen at all. - - A GraphicsObjectContainer can have one element inside it, and it must be a - QGraphicsObject or subclass which has been exposed to the QML engine. - The graphics object inside the GraphicsObjectContainer can then be used - like any other item in QML with the exception of not being reparentable - and not having the standard properties of QML items (such as anchors). - - As the contained object is positioned relative to the container, anchors - affecting the container item will affect the onscreen position of the - contained item. If synchronizedResizing is set to true, then anchors - affecting the container item's size will also affect the contained item's - size. - - Example: - \code - import Qt 4.7 - import MyApp 2.1 as Widgets - Rectangle{ - id: rect - property alias widgetPropertyThree: widget.myThirdProperty; - GraphicsObjectContainer{ - synchronizedResizing: true - anchors.margins: 10 - anchors.fill: parent - Widgets.MyWidget{ - myProperty: "A Value" - myOtherProperty: rect.color - } - } - } - \endcode -*/ - -/*! - \internal - \class QDeclarativeGraphicsObjectContainer - \brief The QDeclarativeGraphicsObjectContainer class allows you to add QGraphicsObjects into Fluid UI applications. -*/ - -QDeclarativeGraphicsObjectContainer::QDeclarativeGraphicsObjectContainer(QDeclarativeItem *parent) -: QDeclarativeItem(*new QDeclarativeGraphicsObjectContainerPrivate, parent) -{ -} - -QDeclarativeGraphicsObjectContainer::~QDeclarativeGraphicsObjectContainer() -{ -} - -QGraphicsObject *QDeclarativeGraphicsObjectContainer::graphicsObject() const -{ - Q_D(const QDeclarativeGraphicsObjectContainer); - return d->graphicsObject; -} - -/*! - \qmlproperty QGraphicsObject GraphicsObjectContainer::graphicsObject - The QGraphicsObject associated with this element. -*/ -void QDeclarativeGraphicsObjectContainer::setGraphicsObject(QGraphicsObject *object) -{ - Q_D(QDeclarativeGraphicsObjectContainer); - if (object == d->graphicsObject) - return; - - //### remove previously set item? - - d->setFiltering(false); - - d->graphicsObject = object; - - if (d->graphicsObject) { - d->graphicsObject->setParentItem(this); - - if (d->syncedResize && d->graphicsObject->isWidget()) { - QGraphicsWidget *gw = static_cast<QGraphicsWidget*>(d->graphicsObject); - QSizeF gwSize = gw->size(); //### should we use sizeHint? - QSizeF newSize = gwSize; - if (heightValid()) - newSize.setHeight(height()); - if (widthValid()) - newSize.setWidth(width()); - if (gwSize != newSize) - gw->resize(newSize); - - gwSize = gw->size(); - setImplicitWidth(gwSize.width()); - setImplicitHeight(gwSize.height()); - - d->setFiltering(true); - } - } -} - -QVariant QDeclarativeGraphicsObjectContainer::itemChange(GraphicsItemChange change, const QVariant &value) -{ - Q_D(QDeclarativeGraphicsObjectContainer); - if (change == ItemSceneHasChanged) { - QGraphicsObject *o = d->graphicsObject; - d->graphicsObject = 0; - setGraphicsObject(o); - } - return QDeclarativeItem::itemChange(change, value); -} - -bool QDeclarativeGraphicsObjectContainer::eventFilter(QObject *watched, QEvent *e) -{ - Q_D(QDeclarativeGraphicsObjectContainer); - if (watched == d->graphicsObject && e->type() == QEvent::GraphicsSceneResize) { - if (d->graphicsObject && d->graphicsObject->isWidget() && d->syncedResize) { - QSizeF newSize = static_cast<QGraphicsWidget*>(d->graphicsObject)->size(); - setImplicitWidth(newSize.width()); - setImplicitHeight(newSize.height()); - } - } - return QDeclarativeItem::eventFilter(watched, e); -} - -/*! - \qmlproperty bool GraphicsObjectContainer::synchronizedResizing - - This property determines whether or not the container and graphics object will synchronize their - sizes. - - \note This property only applies when wrapping a QGraphicsWidget. - - If synchronizedResizing is enabled, the container and widget will - synchronize their sizes as follows. - \list - \o If a size has been set on the container, the widget will be resized to the container. - Any changes in the container's size will be reflected in the widget. - - \o \e Otherwise, the container will initially be sized to the preferred size of the widget. - Any changes to the container's size will be reflected in the widget, and any changes to the - widget's size will be reflected in the container. - \endlist -*/ -bool QDeclarativeGraphicsObjectContainer::synchronizedResizing() const -{ - Q_D(const QDeclarativeGraphicsObjectContainer); - return d->syncedResize; -} - -void QDeclarativeGraphicsObjectContainer::setSynchronizedResizing(bool on) -{ - Q_D(QDeclarativeGraphicsObjectContainer); - if (on == d->syncedResize) - return; - - d->syncedResize = on; - d->setFiltering(on); -} - -void QDeclarativeGraphicsObjectContainerPrivate::_q_updateSize() -{ - if (!graphicsObject || !graphicsObject->isWidget() || !syncedResize) - return; - - QGraphicsWidget *gw = static_cast<QGraphicsWidget*>(graphicsObject); - const QSizeF newSize(width(), height()); - gw->resize(newSize); - - //### will respecting the widgets min/max ever get us in trouble?
