L_LVKRN_API L_INT 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.

Example

This example will set the new hit test settings.

L_INT VecSetHitTestExample(pVECTORHANDLE pVector) 
{ 
   VECTORHITTEST   HitTest;  /* Hittest settings */ 
   /* Allow for 4 pixels error calibration value */ 
   HitTest.nDistance = 4; 
   /* Allow hittest checking to be done inside closed figures as well */ 
   HitTest.dwFlags = VECTOR_HITTEST_CLOSEDFIGURES; 
   /* Set new hittest settings */ 
   return L_VecSetHitTest( pVector, &HitTest ); 
}
