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:
true if no error occurred |
