C++ (Cpp) FormEditorItem::mapFromScene示例

示例#1

void DragTool::createQmlItemNode(const ItemLibraryEntry &itemLibraryEntry, QmlItemNode parentNode, QPointF scenePos)
{
    MetaInfo metaInfo = MetaInfo::global();

    FormEditorItem *parentItem = scene()->itemForQmlItemNode(parentNode);
    QPointF pos = parentItem->mapFromScene(scenePos);

    m_dragNode = view()->createQmlItemNode(itemLibraryEntry, pos, parentNode);

    Q_ASSERT(m_dragNode.modelNode().isValid());

    QList<QmlItemNode> nodeList;
    nodeList.append(m_dragNode);    
    m_selectionIndicator.setItems(scene()->itemsForQmlItemNodes(nodeList));
}

示例#2
