OnCurveDesignerPointsChange event

Previous pageReturn to chapter overviewNext page

Remarks

 

Occurs when the curve inside a volume curve designer control is modified by dragging one of the control points through the mouse interaction.

 

 

This event replaces the usage of the CallbackCurveDesignerPointsChange delegate and is only intended for usage with applications developed using Visual Basic 6 (which results unreliable when dealing with delegates and callbacks) and, in order to be enabled, requires a call to the COMEventsEnable method.

 

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

For details about using Volume Automation refer to the How to manage Volume Automation tutorial.
