L_VecSetHitTest

#include "lvkrn.h"

L_INT EXT_FUNCTION L_VecSetHitTest(pVector, pHitTest)

pVECTORHANDLE pVector;

/* pointer to a vector handle */

const pVECTORHITTEST pHitTest;

/* pointer to a structure */

Sets the new hit test settings.

Parameter

Description

pVector

Pointer to a vector handle.

pHitTest

Pointer to a VECTORHITTEST structure that contains the new hit test settings.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

The hit test settings determine the behavior of the hit test. The hit test itself is performed by calling L_VecHitTest.

To get the current hit test settings, call L_VecGetHitTest.

For more information on possible hit test settings, refer to the VECTORHITTEST structure.
