L_VecGetHitTest

Summary

Gets the current hit test settings.

Syntax

#include "ltvkrn.h"

L_LVKRN_API L_INT L_VecGetHitTest(pVector, pHitTest)

Parameters

const pVECTORHANDLE pVector

Pointer to a vector handle.

pVECTORHITTEST pHitTest

Pointer to a VECTORHITTEST structure to be updated with the current hit test settings.

Returns

Value	Meaning
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.

The hit test settings can be changed by calling L_VecSetHitTest.

For more information on possible hit test settings, refer to the VECTORHITTEST structure.

Example

This example will toggle dwFlags when doing hit testing.

L_LTVKRNTEX_API L_INT VecGetHitTestExample(pVECTORHANDLE pVector) 
{ 
   L_INT nRet; 
   VECTORHITTEST   HitTest;  /* Hittest settings */ 
 
   /* Get the hit test settings */ 
   nRet = L_VecGetHitTest( pVector, &HitTest ); 
   if(nRet != SUCCESS) 
      return nRet; 
 
   /* Toggle checking for closed areas */ 
   if( HitTest.dwFlags & VECTOR_HITTEST_CLOSEDFIGURES ) 
      HitTest.dwFlags &= ~VECTOR_HITTEST_CLOSEDFIGURES; 
   else 
      HitTest.dwFlags |= VECTOR_HITTEST_CLOSEDFIGURES; 
 
   /* Set new hit test settings */ 
   nRet = L_VecSetHitTest( pVector, &HitTest ); 
 
   return nRet;
