These properties provide the size hints + necessary for items to work in conjunction with Qt \l{Graphics View Framework}{Graphics View} layout classes + such as QGraphicsLinearLayout and QGraphicsGridLayout. The Qt layout mechanisms 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 its properties merely expose the QGraphicsLayoutItem functionality to QML. + + The \l{declarative/cppextensions/qgraphicslayouts/layoutitem}{LayoutItem example} + demonstrates how a LayoutItem can be used within a \l{Graphics View Framework}{Graphics View} + scene. +*/ + +/*! + \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 +*/ + +QDeclarative1LayoutItem::QDeclarative1LayoutItem(QDeclarativeItem* parent) + : QDeclarativeItem(parent), m_maximumSize(INT_MAX,INT_MAX), m_minimumSize(0,0), m_preferredSize(0,0) +{ + setGraphicsItem(this); +} + +void QDeclarative1LayoutItem::setGeometry(const QRectF & rect) +{ + setX(rect.x()); + setY(rect.y()); + setWidth(rect.width()); + setHeight(rect.height()); +} + +QSizeF QDeclarative1LayoutItem::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 |
