Property Documentation

itemModel : QAbstractItemModel*

This property holds the item model to use as a data source for a 3D scatter series.

Access functions:

Notifier signal:

rotationRole : QString

This property holds 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 QQuaternion, or as one of the string representations: "scalar,x,y,z" or "@angle,x,y,z". The first will construct the quaternion directly with given values, and the second one will construct the quaternion using QQuaternion::fromAxisAndAngle() method.

Access functions:

Notifier signal:

rotationRolePattern : QRegExp

This property holds whether 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.

Access functions:

Notifier signal:

See also rotationRole and rotationRoleReplace.

rotationRoleReplace : QString

This property holds the replace content to be used in conjunction with the rotation role pattern.

Defaults to an empty string. For more information on how the search and replace using regular expressions works, see QString::replace(const QRegExp &rx, const QString &after) function documentation.

Access functions:

Notifier signal:

See also rotationRole and rotationRolePattern.

xPosRole : QString

This property holds the item model role to map into the X position.

Access functions:

Notifier signal:

xPosRolePattern : QRegExp

This property holds whether 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.

Access functions:

Notifier signal:

See also xPosRole and xPosRoleReplace.

xPosRoleReplace : QString

This property holds the replace content to be used in conjunction with the x position role pattern.

Defaults to an empty string. For more information on how the search and replace using regular expressions works, see QString::replace(const QRegExp &rx, const QString &after) function documentation.

Access functions:

Notifier signal:

See also xPosRole and xPosRolePattern.

yPosRole : QString

This property holds the item model role to map into the Y position.

Access functions:

Notifier signal:

yPosRolePattern : QRegExp

This property holds whether 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.

Access functions:

Notifier signal:

See also yPosRole and yPosRoleReplace.

yPosRoleReplace : QString

This property holds the replace content to be used in conjunction with the y position role pattern.

Defaults to an empty string. For more information on how the search and replace using regular expressions works, see QString::replace(const QRegExp &rx, const QString &after) function documentation.

Access functions:

Notifier signal:

See also yPosRole and yPosRolePattern.

zPosRole : QString

This property holds the item model role to map into the Z position.

Access functions:

Notifier signal:

zPosRolePattern : QRegExp

This property holds whether 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.

Access functions:

Notifier signal:

See also zPosRole and zPosRoleReplace.

zPosRoleReplace : QString

This property holds the replace content to be used in conjunction with the z position role pattern.

Defaults to an empty string. For more information on how the search and replace using regular expressions works, see QString::replace(const QRegExp &rx, const QString &after) function documentation.
