Hi List,
My python plugin changes attribute values in a table using this line:
lyr.changeAttributeValue(feat.id(),fieldNum,result)
It appears to take approximately 250 ms to run single this line of code.
That makes my plugin really slow in case I want to change a lot of
values, which is what I want.
Does anyone know a faster way of doing this?
Thanks,
Raymond
