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:

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.
