CallbackCurveDesignerPointsChange delegate

Previous pageReturn to chapter overviewNext page

Remarks

 

Callback delegate invoked when the curve inside a volume curve designer control is modified by dragging one of the control points through the mouse interaction: this callback can be set through a call to the CallbackCurveDesignerPointsChangeSet method.

 

For further details about callback delegates see the How to synchronize the container application through callback delegates tutorial.

For details about using the Curve Designer refer to the How to create custom volume curves tutorial.
