Proxy class for presenting data in item models with Scatter3D. More...
Import Statement: | import QtDataVisualization |
Since: | QtDataVisualization 1.0 |
Instantiates: | QItemModelScatterDataProxy |
Inherits: |
This type allows you to use AbstractItemModel derived models as a data source for Scatter3D.
The data is resolved asynchronously whenever the mapping or the model changes. QScatterDataProxy::arrayReset() is emitted when the data has been resolved.
For more details, see QItemModelScatterDataProxy documentation.
Usage example:
ItemModelScatterDataProxy { itemModel: model // E.g. a list model defined elsewhere containing point coordinates. // Mapping model roles to scatter series item coordinates. xPosRole: "xPos" yPosRole: "yPos" zPosRole: "zPos" }
See also ScatterDataProxy and Qt Data Visualization Data Handling.
itemModel : model
The item model to use as a data source for Scatter3D.
rotationRole : string
The item model role to map into item rotation. The model may supply the value for rotation as either variant that is directly convertible to quaternion, or as one of the string representations: "scalar,x,y,z"
or "@angle,x,y,z"
. The first format will construct the quaternion directly with given values, and the second one will construct the quaternion using QQuaternion::fromAxisAndAngle() method.
rotationRolePattern : regExp
When set, a search and replace is done on the value mapped by the rotation role before it is used as item rotation. This property specifies the regular expression to find the portion of the mapped value to replace and rotationRoleReplace property contains the replacement string.
See also rotationRole and rotationRoleReplace.
rotationRoleReplace : string
This property defines the replace content to be used in conjunction with rotationRolePattern. Defaults to an empty string. For more information on how the search and replace using regular expressions works, see QString::replace(const QRegularExpression &rx, const QString &after) function documentation.
See also rotationRole and rotationRolePattern.
xPosRole : string
The item model role to map into the X position.
xPosRolePattern : regExp
When set, a search and replace is done on the value mapped by the x position role before it is used as an item position value. This property specifies the regular expression to find the portion of the mapped value to replace and xPosRoleReplace property contains the replacement string.
See also xPosRole and xPosRoleReplace.
xPosRoleReplace : string
This property defines the replace content to be used in conjunction with xPosRolePattern. Defaults to an empty string. For more information on how the search and replace using regular expressions works, see QString::replace(const QRegularExpression &rx, const QString &after) function documentation.
See also xPosRole and xPosRolePattern.
yPosRole : string
The item model role to map into the Y position.
yPosRolePattern : regExp
When set, a search and replace is done on the value mapped by the y position role before it is used as an item position value. This property specifies the regular expression to find the portion of the mapped value to replace and yPosRoleReplace property contains the replacement string.
See also yPosRole and yPosRoleReplace.
yPosRoleReplace : string
This property defines the replace content to be used in conjunction with yPosRolePattern. Defaults to an empty string. For more information on how the search and replace using regular expressions works, see QString::replace(const QRegularExpression &rx, const QString &after) function documentation.
See also yPosRole and yPosRolePattern.
zPosRole : string
The item model role to map into the Z position.
zPosRolePattern : regExp
When set, a search and replace is done on the value mapped by the z position role before it is used as an item position value. This property specifies the regular expression to find the portion of the mapped value to replace and zPosRoleReplace property contains the replacement string.
See also zPosRole and zPosRoleReplace.
zPosRoleReplace : string
This property defines the replace content to be used in conjunction with zPosRolePattern. Defaults to an empty string. For more information on how the search and replace using regular expressions works, see QString::replace(const QRegularExpression &rx, const QString &after) function documentation.
