L_LVKRN_API L_INT L_VecGetHitTest(pVector, pHitTest)
Pointer to a vector handle.
Pointer to a VECTORHITTEST structure to be updated with the current hit test settings.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
The hit test settings determine the behavior of the hit test. The hit test itself is performed by calling L_VecHitTest.
The hit test settings can be changed by calling L_VecSetHitTest.
For more information on possible hit test settings, refer to the VECTORHITTEST structure.
This example will toggle dwFlags when doing hit testing.
