| * \inmodule QtDataVisualization |
| * \brief Proxy class for presenting data in item models with Q3DBars. |
| * \since QtDataVisualization 1.0 |
| * |
| * QItemModelBarDataProxy allows you to use QAbstractItemModel derived models as a data source |
| * for Q3DBars. 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}. |
