#include "lvkrn.h"
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 ); }
