Performance Considerations

Internally, the GtkListStore is implemented with a linked list with a tail pointer. As a result, it is fast at data insertion and deletion, and not as fast at random data access. The GtkListStore sets the GTK_TREE_MODEL_ITERS_PERSIST flag, which means that GtkTreeIters can be cached while the row exists. Thus, if access to a particular row is needed often, it is worth keeping the iter around.

struct GtkListStore

struct GtkListStore;

gtk_list_store_new ()

GtkListStore* gtk_list_store_new            (gint n_columns,
                                             ...);

Creates a new list store as with n_columns columns each of the types passed in. As an example, gtk_tree_store_new (3, G_TYPE_INT, G_TYPE_STRING, GDK_TYPE_PIXBUF); will create a new GtkListStore with three columns, of type int, string and GdkPixbuf respectively.

gtk_list_store_newv ()

GtkListStore* gtk_list_store_newv           (gint n_columns,
                                             GType *types);

Non-vararg creation function. Used primarily by language bindings.

gtk_list_store_set_column_types ()

void        gtk_list_store_set_column_types (GtkListStore *list_store,
                                             gint n_columns,
                                             GType *types);

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

gtk_list_store_set ()

void        gtk_list_store_set              (GtkListStore *list_store,
                                             GtkTreeIter *iter,
                                             ...);

Sets the value of one or more cells in the row referenced by iter. The variable argument list should contain integer column numbers, each column number followed by the value to be set. The list is terminated by a -1. For example, to set column 0 with type G_TYPE_STRING to "Foo", you would write gtk_list_store_set (store, iter, 0, "Foo", -1).

gtk_list_store_set_valist ()

void        gtk_list_store_set_valist       (GtkListStore *list_store,
                                             GtkTreeIter *iter,
                                             va_list var_args);

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

gtk_list_store_set_value ()

void        gtk_list_store_set_value        (GtkListStore *list_store,
                                             GtkTreeIter *iter,
                                             gint column,
                                             GValue *value);

Sets the data in the cell specified by iter and column. The type of value must be convertible to the type of the column.

gtk_list_store_remove ()

gboolean    gtk_list_store_remove           (GtkListStore *list_store,
                                             GtkTreeIter *iter);

Removes the given row from the list store. After being removed, iter is set to be the next valid row, or invalidated if it pointed to the last row in list_store.

gtk_list_store_insert ()

void        gtk_list_store_insert           (GtkListStore *list_store,
                                             GtkTreeIter *iter,
                                             gint position);

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 empty before this function is called. To fill in values, you need to call gtk_list_store_set() or gtk_list_store_set_value().

gtk_list_store_insert_before ()

void        gtk_list_store_insert_before    (GtkListStore *list_store,
                                             GtkTreeIter *iter,
                                             GtkTreeIter *sibling);

Inserts a new row before sibling. If sibling is NULL, then the row will be appended to the end of the list. iter will be changed to point to this new row. The row will be empty before this function is called. To fill in values, you need to call gtk_list_store_set() or gtk_list_store_set_value().

gtk_list_store_insert_after ()

void        gtk_list_store_insert_after     (GtkListStore *list_store,
                                             GtkTreeIter *iter,
                                             GtkTreeIter *sibling);

Inserts a new row after sibling. If sibling is NULL, then the row will be prepended to the beginning 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_list_store_set() or gtk_list_store_set_value().

gtk_list_store_prepend ()

void        gtk_list_store_prepend          (GtkListStore *list_store,
                                             GtkTreeIter *iter);

Prepends a new row to list_store. 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_list_store_set() or gtk_list_store_set_value().

gtk_list_store_append ()

void        gtk_list_store_append           (GtkListStore *list_store,
                                             GtkTreeIter *iter);

Appends a new row to list_store. 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_list_store_set() or gtk_list_store_set_value().

gtk_list_store_clear ()

void        gtk_list_store_clear            (GtkListStore *list_store);

Removes all rows from the list store.

gtk_list_store_iter_is_valid ()

gboolean    gtk_list_store_iter_is_valid    (GtkListStore *list_store,
                                             GtkTreeIter *iter);

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