move_to_row
Description:
Synchronizes the values of the parameters in this with the values at the row row.
If row is not a valid row, then the returned value is false, and the "current-row" property is set to -1 (which means
that is_valid would return false), with the exception that
if row is -1, then the returned value is true.
This function can return false if it was not allowed to be moved (as it emits the "validate-set" signal before being moved).
When this function returns true, then this has actually been moved to the next row, but some
values may not have been read correctly in the row, in which case the correcsponding Holder
will be left invalid.
Parameters:
| this |
a DataModelIter object |
| row |
the row to set this to |
Returns:
