示例1: handleAttributeAdded
void QgsVectorLayerEditBuffer::handleAttributeAdded( int index )
{
// go through the changed attributes map and adapt indices
for ( int i = 0; i < mChangedAttributeValues.size(); ++i )
{
updateAttributeMapIndex( mChangedAttributeValues[i], index, + 1 );
}
// go through added features and adapt attributes
QgsFeatureMap::iterator featureIt = mAddedFeatures.begin();
for ( ; featureIt != mAddedFeatures.end(); ++featureIt )
{
QgsAttributes& attrs = featureIt->attributes();
attrs.insert( index, QVariant() );
}
}示例2: handleAttributeDeleted
void QgsVectorLayerEditBuffer::handleAttributeDeleted( int index )
{
// go through the changed attributes map and adapt indices
for ( int i = 0; i < mChangedAttributeValues.size(); ++i )
{
QgsAttributeMap& attrMap = mChangedAttributeValues[i];
// remove the attribute
if ( attrMap.contains( index ) )
attrMap.remove( index );
// update attribute indices
updateAttributeMapIndex( attrMap, index, -1 );
}
// go through added features and adapt attributes
QgsFeatureMap::iterator featureIt = mAddedFeatures.begin();
