详细描述

QItemModelSurfaceDataProxy allows you to use QAbstractItemModel derived models as a data source for Q3DSurface . It uses the defined mappings to map data from the model to rows, columns, and surface points of Q3DSurface graph.

Data is resolved asynchronously whenever the mapping or the model changes. QSurfaceDataProxy::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:

若 useModelCategories property is set to true , this proxy will map rows and columns of QAbstractItemModel to rows and columns of Q3DSurface , and uses the value returned for Qt::DisplayRole as Y-position by default. Row and column headers are used for Z-position and X-position by default, if they can be converted to floats. Otherwise row and column indices are used. The Y-position role to be used can be redefined if Qt::DisplayRole is not suitable. The Z-position and X-position roles to be used can be redefined if the headers or indices are not suitable.
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 Y-position.
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.

For example, assume that you have a custom QAbstractItemModel storing surface topography data. Each item in the model has the roles "longitude", "latitude", and "height". The item model already contains the data properly sorted so that longitudes and latitudes are first encountered in correct order, which enables us to utilize the row and column category autogeneration. You could do the following to display the data in a surface graph:

QItemModelSurfaceDataProxy *proxy = new QItemModelSurfaceDataProxy(customModel,
                                                                   QStringLiteral("longitude"), // Row role
                                                                   QStringLiteral("latitude"), // Column role
                                                                   QStringLiteral("height")); // Y-position role

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 QRegularExpression &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 ItemModelBarDataProxy usage in Simple Bar Graph 范例。

enum QItemModelSurfaceDataProxy:: MultiMatchBehavior

Behavior types for QItemModelSurfaceDataProxy::multiMatchBehavior 特性。

常量	值	描述
`QItemModelSurfaceDataProxy::MMBFirst`	`0`	The position values are taken from the first item in the item model that matches each row/column combination.
`QItemModelSurfaceDataProxy::MMBLast`	`1`	The position values are taken from the last item in the item model that matches each row/column combination.
`QItemModelSurfaceDataProxy::MMBAverage`	`2`	The position values from all items matching each row/column combination are averaged together and the averages are used as the surface point position.
`QItemModelSurfaceDataProxy::MMBCumulativeY`	`3`	For X and Z values this acts just like `MMBAverage` , but Y values are added together instead of averaged and the total is used as the surface point Y position.
