The Qt Layout will resize the LayoutItem as appropriate, + taking its size hints into account, and you can propagate this to the other elements in your UI via anchors and bindings. + + This is a QGraphicsLayoutItem subclass, and the properties merely expose the QGraphicsLayoutItem functionality to QML. + See the QGraphicsLayoutItem documentation for further details. +*/ + +/*! + \internal + \class QDeclarativeLayoutItem + \brief The QDeclarativeLayoutItem class allows you to place your Fluid UI elements inside a classical Qt layout. +*/ + + +/*! + \qmlproperty QSizeF LayoutItem::maximumSize + + The maximumSize property can be set to specify the maximum desired size of this LayoutItem +*/ + +/*! + \qmlproperty QSizeF LayoutItem::minimumSize + + The minimumSize property can be set to specify the minimum desired size of this LayoutItem +*/ + +/*! + \qmlproperty QSizeF LayoutItem::preferredSize + + The preferredSize property can be set to specify the preferred size of this LayoutItem +*/ + +QDeclarativeLayoutItem::QDeclarativeLayoutItem(QDeclarativeItem* parent) + : QDeclarativeItem(parent), m_maximumSize(INT_MAX,INT_MAX), m_minimumSize(0,0), m_preferredSize(0,0) +{ + setGraphicsItem(this); +} + +void QDeclarativeLayoutItem::setGeometry(const QRectF & rect) +{ + setX(rect.x()); + setY(rect.y()); + setWidth(rect.width()); + setHeight(rect.height()); +} + +QSizeF QDeclarativeLayoutItem::sizeHint(Qt::SizeHint w, const QSizeF &constraint) const +{ + Q_UNUSED(constraint); + if(w == Qt::MinimumSize){ + return m_minimumSize; + }else if(w == Qt::MaximumSize){ + return m_maximumSize; + }else{ + return m_preferredSize; + } +} + +QT_END_NAMESPACE |
