iter_children

Description:

public abstract bool iter_children (out TreeIter iter, TreeIter? parent)

Sets iter to point to the first child of parent.

If parent has no children, false is returned and iter is set to be invalid. parent will remain a valid node after this function has been called.

If parent is null returns the first node, equivalent to `gtk_tree_model_get_iter_first ( tree_model, iter);`

Parameters:

this	a TreeModel
iter	the new TreeIter-struct to be set to the child
parent	the TreeIter-struct, or null

Returns:

true, if iter has been set to the first child
