VECTORHITTEST

typedef  struct  tagVECTORHITTEST 
{ 
   L_INT  nSize; 
   L_INT  nDistance; 
   L_UINT32  dwFlags; 
}  VECTORHITTEST,  *  pVECTORHITTEST; 

The VECTORHITTEST structure holds information about hit test options.

Members

L_INT nSize

Size of this structure. Used for versioning.

L_INT nDistance

Distance from the point, in pixels. This value indicates how close the point must be to an object in order to "hit" the object.

L_UINT32 dwFlags

Flag that determines which objects to consider when hit testing. Possible values are:

Value Meaning
VECTOR_HITTEST_CLOSEDFIGURES Determine whether the hit test point is inside closed objects.
VECTOR_HITTEST_IGNORESELECTED Do not test objects that are already selected.

Comments

The L_VecGetHitTest and L_VecSetHitTest functions, get and set the current hit test options. The L_VecHitTest actually performs the hit test.

The hit test options must be set before calling the L_VecHitTest function.

pVECTORHITTEST is a pointer to a VECTORHITTEST structure.
