The T object is a list model for use with a Gtk.Gtk.TreeView.T widget. It implements the Gtk.Gtk.TreeModel.T interface, and consequentialy, can use all of the methods available there. It also implements the Gtk.Gtk.TreeSortable.T interface so it can be sorted by the view. Finally, it also implements the tree drag and drop interfaces.

Non vararg creation function. Used primarily by language bindings.

Non vararg creation function. Used primarily by language bindings.

Appends a new row to tree_store. If parent is non-NULL, then it will append the new row after the last child of parent, otherwise it will append a row to the top level. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or SetValue.

Removes all rows from tree_store

Creates a new row at position. If parent is non-NULL, then the row will be made a child of parent. Otherwise, the row will be created at the toplevel. If position is larger than the number of rows at that level, then the new row will be inserted to the end of the list. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or SetValue.

Inserts a new row after sibling. If sibling is NULL, then the row will be prepended to parent 's children. If parent and sibling are NULL, then the row will be prepended to the toplevel. If both sibling and parent are set, then parent must be the parent of sibling. When sibling is set, parent is optional.

iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or SetValue.

Inserts a new row before sibling. If sibling is NULL, then the row will be appended to parent 's children. If parent and sibling are NULL, then the row will be appended to the toplevel. If both sibling and parent are set, then parent must be the parent of sibling. When sibling is set, parent is optional.

iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or SetValue.

Creates a new row at position. iter will be changed to point to this new row. If position is larger than the number of rows on the list, then the new row will be appended to the list. The row will be filled with the values given to this function.

Calling gtk_tree_store_insert_with_values (tree_store, iter, position, ...) has the same effect as calling

gtk_tree_store_insert (tree_store, iter, position);
gtk_tree_store_set (tree_store, iter, ...);

A variant of InsertWithValues which takes the columns and values as two arrays, instead of varargs. This function is mainly intended for language bindings.

Returns TRUE if iter is an ancestor of descendant. That is, iter is the parent (or grandparent or great-grandparent) of descendant.

Returns the depth of iter. This will be 0 for anything on the root level, 1 for anything down a level, etc.

WARNING: This function is slow. Only use it for debugging and/or testing purposes.

Checks if the given iter is a valid iter for this T.

Moves iter in tree_store to the position after position. iter and position should be in the same level. Note that this function only works with unsorted stores. If position is NULL, iter will be moved to the start of the level.

Moves iter in tree_store to the position before position. iter and position should be in the same level. Note that this function only works with unsorted stores. If position is NULL, iter will be moved to the end of the level.

Prepends a new row to tree_store. If parent is non-NULL, then it will prepend the new row before the first child of parent, otherwise it will prepend a row to the top level. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or SetValue.

Removes iter from tree_store. After being removed, iter is set to the next valid row at that level, or invalidated if it previously pointed to the last one.

Reorders the children of parent in tree_store to follow the order indicated by new_order. Note that this function only works with unsorted stores.

See gtk_tree_store_set(); this version takes a va_list for use by language bindings.

This function is meant primarily for GObjects that inherit from T, and should only be used when constructing a new T. It will not function after a row has been added, or a method on the Gtk.Gtk.TreeModel.T interface is called.

See gtk_tree_store_set(); this version takes a va_list for use by language bindings.

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 variant of SetValist which takes the columns and values as two arrays, instead of varargs. This function is mainly intended for language bindings or in case the number of columns to change is not known until run-time.

Swaps a and b in the same level of tree_store. Note that this function only works with unsorted stores.
