You can see how is GetField working:
PdfField PdfPage::GetField( int index )
{
int nCount = 0;
int nAnnots = this->GetNumAnnots();
PdfAnnotation* pAnnot = NULL;
for( int i=0;i<nAnnots;i++ )
{
pAnnot = this->GetAnnotation( i );
// Count every widget annotation with a FieldType as PdfField
if( pAnnot->GetType() == ePdfAnnotation_Widget )
{
if( nCount == index )
{
return PdfField( pAnnot->GetObject(), pAnnot );
}
else
++nCount;
}
}
PODOFO_RAISE_ERROR( ePdfError_ValueOutOfRange );
}
