This example will determine whether or not the object under the given point is selected.
L_INT VecIsObjectSelectedExample( pVECTORHANDLE pVector, POINT* pPoint) { VECTOROBJECT Object; /* Object under point */ L_INT nRet; /* Get object under that point */ nRet = L_VecHitTest( pVector, pPoint, &Object ); /* Is there an object under that point? */ if( nRet == SUCCESS ) { /* Show the selection state of the object */ if( L_VecIsObjectSelected( pVector, &Object ) ) MessageBox(NULL, TEXT("Object is selected."), TEXT("Test"), MB_OK); else MessageBox(NULL, TEXT("Object is not selected."), TEXT("Test"), MB_OK); } return nRet; }
