GdaDataProxy
Proxy to hold modifications for any #GdaDataModel, and provides the #GdaDataModel interface itself
This object stores modifications made to a #GdaDataModel object which is proxied until asked to make the changes
inside the #GdaDataModel, it also filters the proxied data model to show only a sample (a defined number of continuous
rows) of it.
Specifically, for a proxied data model having nb_cols columns and nb_rows rows,
the #GdaDataProxy object has the following attributes:
2 * nb_cols columns:
the first (>= 0) nb_cols columns are the current values stored in the
proxy (which correspond to the values of the proxied data model if the considered row has not been
changed). The associated values are writable.
the last nb_cols columns are the values stored in the proxied data model,
at column col - nb_cols
a variable number of rows depending on the following attributes:
if the proxy is configured to have an empty row as the first row
if the proxy only displays parts of the proxied data model
if new rows have been added to the proxy
Note that unless explicitely mentionned, the columns are read-only.
