Description

Functions

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. 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 GtkListStore with three columns, of type int, string and GdkPixbuf respectively.

Parameters

n_columns

number of columns in the list store

 

Varargs

all GType types for the columns, from first to last

 

Returns

a new GtkListStore


gtk_list_store_newv ()

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

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

Parameters

n_columns

number of columns in the list store

 

types

an array of GType types for the columns, from first to last.

[array length=n_columns]

Returns

a new GtkListStore.

[transfer none]


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.

Parameters

list_store

A GtkListStore

 

n_columns

Number of columns for the list store

 

types

An array length n of GTypes.

[array length=n_columns]

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).

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.

Parameters

list_store

a GtkListStore

 

iter

row iterator

 

Varargs

pairs of column number and value, terminated with -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.

Parameters

list_store

A GtkListStore

 

iter

A valid GtkTreeIter for the row being modified

 

var_args

va_list of column/value pairs

 

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.

Parameters

list_store

A GtkListStore

 

iter

A valid GtkTreeIter for the row being modified

 

column

column number to modify

 

value

new value for the cell

 

gtk_list_store_set_valuesv ()

void
gtk_list_store_set_valuesv (GtkListStore *list_store,
                            GtkTreeIter *iter,
                            gint *columns,
                            GValue *values,
                            gint n_values);

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

Parameters

list_store

A GtkListStore

 

iter

A valid GtkTreeIter for the row being modified

 

columns

an array of column numbers.

[array length=n_values]

values

an array of GValues.

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 .

Parameters

list_store

A GtkListStore

 

iter

A valid GtkTreeIter

 

Returns

TRUE if iter is valid, FALSE if not.


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

Parameters

list_store

A GtkListStore

 

iter

An unset GtkTreeIter to set to the new row.

[out]

position

position to insert the new row

 

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

Parameters

list_store

A GtkListStore

 

iter

An unset GtkTreeIter to set to the new row.

[out]

sibling

A valid GtkTreeIter, or NULL.

[allow-none]

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().

Parameters

list_store

A GtkListStore

 

iter

An unset GtkTreeIter to set to the new row.

[out]

sibling

A valid GtkTreeIter, or NULL.

[allow-none]

gtk_list_store_insert_with_values ()

void
gtk_list_store_insert_with_values (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 filled with the values given to this function.

Calling gtk_list_store_insert_with_values(list_store, iter, position...) has the same effect as calling

1
2
gtk_list_store_insert (list_store, iter, position);
gtk_list_store_set (list_store, iter, ...);

with the difference that the former will only emit a row_inserted signal, while the latter will emit row_inserted, row_changed and, if the list store is sorted, rows_reordered. Since emitting the rows_reordered signal repeatedly can affect the performance of the program, gtk_list_store_insert_with_values() should generally be preferred when inserting rows in a sorted list store.

Parameters

list_store

A GtkListStore

 

iter

An unset GtkTreeIter to set to the new row, or NULL.

[out][allow-none]

position

position to insert the new row

 

Varargs

pairs of column number and value, terminated with -1

                                    gint position,
                                    gint *columns,
