move_to_row

Description:

public virtual bool move_to_row (int row)

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
