Functions
gtk_tree_store_new ()
GtkTreeStore *
gtk_tree_store_new (gint n_columns,
...);
Creates a new tree store as with n_columns
columns each of the types passed
in. Note that only types derived from standard GObject fundamental types
are supported.
As an example, gtk_tree_store_new (3, G_TYPE_INT, G_TYPE_STRING,
GDK_TYPE_PIXBUF); will create a new GtkTreeStore with three columns, of type
gint, gchararray, and GdkPixbuf respectively.
gtk_tree_store_newv ()
GtkTreeStore *
gtk_tree_store_newv (gint n_columns,
GType *types);
Non vararg creation function. Used primarily by language bindings.

gtk_tree_store_set_column_types ()
void
gtk_tree_store_set_column_types (GtkTreeStore *tree_store,
gint n_columns,
GType *types);
This function is meant primarily for GObjects that inherit from
GtkTreeStore, and should only be used when constructing a new
GtkTreeStore. It will not function after a row has been added,
or a method on the GtkTreeModel interface is called.
gtk_tree_store_set_value ()
void
gtk_tree_store_set_value (GtkTreeStore *tree_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_tree_store_set ()
void
gtk_tree_store_set (GtkTreeStore *tree_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_tree_store_set (store, iter, 0, "Foo", -1).
The value will be referenced by the store if it is a G_TYPE_OBJECT, and it
will be copied if it is a G_TYPE_STRING or G_TYPE_BOXED.
gtk_tree_store_set_valuesv ()
void
gtk_tree_store_set_valuesv (GtkTreeStore *tree_store,
GtkTreeIter *iter,
gint *columns,
GValue *values,
gint n_values);
A variant of gtk_tree_store_set_valist() 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.

gtk_tree_store_remove ()
gboolean
gtk_tree_store_remove (GtkTreeStore *tree_store,
GtkTreeIter *iter);
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.
Returns
TRUE if iter
is still valid, FALSE if not.
gtk_tree_store_insert ()
void
gtk_tree_store_insert (GtkTreeStore *tree_store,
GtkTreeIter *iter,
GtkTreeIter *parent,
gint position);
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 -1 or 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
gtk_tree_store_set_value().
gtk_tree_store_insert_before ()
void
gtk_tree_store_insert_before (GtkTreeStore *tree_store,
GtkTreeIter *iter,
GtkTreeIter *parent,
GtkTreeIter *sibling);
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 gtk_tree_store_set_value().
gtk_tree_store_insert_after ()
void
gtk_tree_store_insert_after (GtkTreeStore *tree_store,
GtkTreeIter *iter,
GtkTreeIter *parent,
GtkTreeIter *sibling);
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 gtk_tree_store_set_value().
gtk_tree_store_insert_with_values ()
void
gtk_tree_store_insert_with_values (GtkTreeStore *tree_store,
GtkTreeIter *iter,
GtkTreeIter *parent,
gint position,
...);
Creates a new row at position
. iter
will be changed to point to this
new row. If position
is -1, or 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
with the different that the former will only emit a row_inserted signal,
while the latter will emit row_inserted, row_changed and if the tree store
is sorted, rows_reordered. Since emitting the rows_reordered signal
repeatedly can affect the performance of the program,
gtk_tree_store_insert_with_values() should generally be preferred when
inserting rows in a sorted tree store.
Since: 2.10
gtk_tree_store_insert_with_valuesv ()
void
gtk_tree_store_insert_with_valuesv (GtkTreeStore *tree_store,
GtkTreeIter *iter,
GtkTreeIter *parent,
gint position,
gint *columns,
GValue *values,
gint n_values);
A variant of gtk_tree_store_insert_with_values() which takes
the columns and values as two arrays, instead of varargs. This
function is mainly intended for language bindings.

Since: 2.10
gtk_tree_store_prepend ()
void
gtk_tree_store_prepend (GtkTreeStore *tree_store,
GtkTreeIter *iter,
GtkTreeIter *parent);
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 gtk_tree_store_set_value().
gtk_tree_store_append ()
void
gtk_tree_store_append (GtkTreeStore *tree_store,
GtkTreeIter *iter,
GtkTreeIter *parent);
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 gtk_tree_store_set_value().
gtk_tree_store_is_ancestor ()
gboolean
gtk_tree_store_is_ancestor (GtkTreeStore *tree_store,
GtkTreeIter *iter,
GtkTreeIter *descendant);

is an ancestor of descendant
gtk_tree_store_iter_depth ()
gint
gtk_tree_store_iter_depth (GtkTreeStore *tree_store,
