Content:

Creation methods:

• public TreeStore (int n_columns, ...)
  Creates a new tree store as with n_columns columns each of the types passed in.
• public TreeStore.newv (Type[] types)
  Non vararg creation function.

Methods:

• public void @set (TreeIter iter, ...)
  Sets the value of one or more cells in the row referenced by iter .
• public void append (out TreeIter iter, TreeIter? parent)
  Appends a new row to this.
• public void clear ()
  Removes all rows from this
• public void insert (out TreeIter iter, TreeIter? parent, int position)
  Creates a new row at position.
• public void insert_after (out TreeIter iter, TreeIter? parent, TreeIter? sibling)
  Inserts a new row after sibling.
• public void insert_before (out TreeIter iter, TreeIter? parent, TreeIter? sibling)
  Inserts a new row before sibling.
• public void insert_with_values (out TreeIter iter, TreeIter? parent, int position, ...)
  Creates a new row at position.
• public void insert_with_valuesv (out TreeIter iter, TreeIter? parent, int position, int[] columns, Value[] values)
  A variant of insert_with_values which takes the columns and values as two arrays, instead of varargs.
• public bool is_ancestor (TreeIter iter, TreeIter descendant)
  Returns true if iter is an ancestor of descendant.
• public int iter_depth (TreeIter iter)
  Returns the depth of iter.
• public bool iter_is_valid (TreeIter iter)
  WARNING: This function is slow.
• public void move_after (ref TreeIter iter, TreeIter? position)
  Moves iter in this to the position after position.
• public void move_before (ref TreeIter iter, TreeIter? position)
  Moves iter in this to the position before position.
• public void prepend (out TreeIter iter, TreeIter? parent)
  Prepends a new row to this.
• public bool remove (ref TreeIter iter)
  Removes iter from this.
• public void reorder (TreeIter? parent, int[] new_order)
  Reorders the children of parent in this to follow the order indicated by new_order.
• public void set_column_types (Type[] types)
  This function is meant primarily for Objects that inherit from TreeStore, and should only be used when constructing a new TreeStore.
• public void set_valist (TreeIter iter, va_list var_args)
  See @set; this version takes a va_list for use by language bindings.
• public void set_value (TreeIter iter, int column, Value value)
  Sets the data in the cell specified by iter and column .
• public void set_valuesv (TreeIter iter, int[] columns, Value[] values)
  A variant of set_valist which takes the columns and values as two arrays, instead of varargs.
• public void swap (TreeIter a, TreeIter b)
  Swaps a and b in the same level of this.
