Reorders the children of parent in self to follow the order
indicated by new_order. Note that this function only works with
unsorted stores.
A TreeIter, or None
an array of integers mapping the new position of each child
to its old position before the re-ordering,
i.e. new_order``[newpos] = oldpos.
Sets the data in the cell specified by iter and column.
The type of value must be convertible to the type of the
column.
A valid TreeIter for the row being modified
column number to modify
new value for the cell
