It uses the defined mappings to map data from the model to rows, columns, and * values of Q3DBars graph. * * The data is resolved asynchronously whenever mappings or the model changes. * QBarDataProxy::arrayReset() is emitted when the data has been resolved. * However, when useModelCategories property is set to true, single item changes are resolved * synchronously, unless the same frame also contains a change that causes the whole model to be * resolved. * * Mappings can be used in the following ways: * * \list * \li If useModelCategories property is set to true, this proxy will map rows and * columns of QAbstractItemModel directly to rows and columns of Q3DBars, and uses the value * returned for Qt::DisplayRole as bar value by default. * The value role to be used can be redefined if Qt::DisplayRole is not suitable. * * \li For models that do not have data already neatly sorted into rows and columns, such as * QAbstractListModel based models, you can define a role from the model to map for each of row, * column and value. * * \li If you do not want to include all data contained in the model, or the autogenerated rows and * columns are not ordered as you wish, you can specify which rows and columns should be included * and in which order by defining an explicit list of categories for either or both of rows and * columns. * \endlist * * For example, assume that you have a custom QAbstractItemModel for storing various monthly values * related to a business. * Each item in the model has the roles "year", "month", "income", and "expenses". * You could do the following to display the data in a bar graph: * * \snippet doc_src_qtdatavisualization.cpp 3 * * If the fields of the model do not contain the data in the exact format you need, you can specify * a search pattern regular expression and a replace rule for each role to get the value in a * format you need. For more information how the replace using regular expressions works, see * QString::replace(const QRegExp &rx, const QString &after) function documentation. Note that * using regular expressions has an impact on the performance, so it's more efficient to utilize * item models where doing search and replace is not necessary to get the desired values. * * For example about using the search patterns in conjunction with the roles, see * \l{Qt Quick 2 Bars Example}. * * \sa {Qt Data Visualization Data Handling} */ /*! * \qmltype ItemModelBarDataProxy * \inqmlmodule QtDataVisualization * \since QtDataVisualization 1.0 * \ingroup datavisualization_qml * \instantiates QItemModelBarDataProxy * \inherits BarDataProxy * \brief Proxy class for presenting data in item models with Bars3D. * * This type allows you to use AbstractItemModel derived models as a data source for Bars3D. * * Data is resolved asynchronously whenever the mapping or the model changes. * QBarDataProxy::arrayReset() is emitted when the data has been resolved. * * For ItemModelBarDataProxy enums, see \l{QItemModelBarDataProxy::MultiMatchBehavior}. * * For more details, see QItemModelBarDataProxy documentation. * * Usage example: * * \snippet doc_src_qmldatavisualization.cpp 7 * * \sa BarDataProxy, {Qt Data Visualization Data Handling} */ /*! * \qmlproperty model ItemModelBarDataProxy::itemModel * The item model. */ /*! * \qmlproperty string ItemModelBarDataProxy::rowRole * The item model role to map into row category. */ /*! * \qmlproperty string ItemModelBarDataProxy::columnRole * The item model role to map into column category. */ /*! * \qmlproperty string ItemModelBarDataProxy::valueRole * The item model role to map into bar value. */ /*! * \qmlproperty string ItemModelBarDataProxy::rotationRole * The item model role to map into bar rotation angle. */ /*! * \qmlproperty list ItemModelBarDataProxy::rowCategories * The row categories of the mapping.
