## Description

A GtkListBox is a vertical container that contains GtkListBoxRow children. These rows can by dynamically sorted and filtered, and headers can be added dynamically depending on the row content. It also allows keyboard and mouse navigation and selection like a typical list.

Using GtkListBox is often an alternative to GtkTreeView, especially when the list contents has a more complicated layout than what is allowed by a GtkCellRenderer, or when the contents is interactive (i.e. has a button in it).

Although a GtkListBox must have only GtkListBoxRow children you can add any kind of widget to it via `gtk_container_add()`, and a GtkListBoxRow widget will automatically be inserted between the list and the widget.

GtkListBoxRows can be marked as activatable or selectable. If a row is activatable, “row-activated” will be emitted for it when the user tries to activate it. If it is selectable, the row will be marked as selected when the user tries to select it.

The GtkListBox widget was added in GTK+ 3.10.

## Functions

### GtkListBoxFilterFunc ()

    gboolean
    (*GtkListBoxFilterFunc) (GtkListBoxRow *row,
                             gpointer user_data);

Will be called whenever the row changes or is added and lets you control if the row should be visible or not.

#### Parameters

row | the row that may be filtered |
user_data | user data. | [closure]

#### Returns

`TRUE` if the row should be visible, `FALSE` otherwise

Since 3.10

### GtkListBoxSortFunc ()

                           GtkListBoxRow *row2,
                           gpointer user_data);

Compare two rows to determine which should be first.

#### Parameters

row1 | the first row |
row2 | the second row |
user_data | user data. | [closure]

#### Returns

< 0 if `row1` should be before `row2` , 0 if they are equal and > 0 otherwise

Since 3.10

### GtkListBoxUpdateHeaderFunc ()

    void
    (*GtkListBoxUpdateHeaderFunc) (GtkListBoxRow *row,

                                   gpointer user_data);

Whenever `row` changes or which row is before `row` changes this is called, which lets you update the header on `row` . You may remove or set a new one via `gtk_list_box_row_set_header()` or just change the state of the current header widget.

#### Parameters

row | the row to update |
before | the row before `row` , or `NULL` if it is first. | [allow-none]

[transfer none]

Since 3.10

### gtk_list_box_invalidate_filter ()

    void
    gtk_list_box_invalidate_filter (GtkListBox *box);

Update the filtering for all rows. Call this when result of the filter function on the `box` is changed due to an external factor. For instance, this would be used if the filter function just looked for a specific search string and the entry with the search string has changed.

#### Parameters

box | a GtkListBox |

Since 3.10

### gtk_list_box_invalidate_headers ()

    void
    gtk_list_box_invalidate_headers (GtkListBox *box);

Update the separators for all rows. Call this when result of the header function on the `box` is changed due to an external factor.

#### Parameters

box | a GtkListBox |

Since 3.10

### gtk_list_box_invalidate_sort ()

    void
    gtk_list_box_invalidate_sort (GtkListBox *box);

Update the sorting for all rows. Call this when result of the sort function on the `box` is changed due to an external factor.

#### Parameters

### gtk_list_box_set_filter_func ()

    void
    gtk_list_box_set_filter_func (GtkListBox *box,
                                  GtkListBoxFilterFunc filter_func,
                                  gpointer user_data,
                                  GDestroyNotify destroy);

By setting a filter function on the `box` one can decide dynamically which of the rows to show. For instance, to implement a search function on a list that filters the original list to only show the matching rows.

The `filter_func` will be called for each row after the call, and it will continue to be called each time a row changes (via `gtk_list_box_row_changed()`) or when `gtk_list_box_invalidate_filter()` is called.

#### Parameters

box | a GtkListBox |
filter_func | callback that lets you filter which rows to show. | [closure user_data][allow-none]
user_data | user data passed to `filter_func` |
destroy | destroy notifier for `user_data` |

Since 3.10

### gtk_list_box_set_header_func ()

    void
    gtk_list_box_set_header_func (GtkListBox *box,
                                  GtkListBoxUpdateHeaderFunc update_header,
                                  gpointer user_data,
                                  GDestroyNotify destroy);

By setting a header function on the `box` one can dynamically add headers in front of rows, depending on the contents of the row and its position in the list. For instance, one could use it to add headers in front of the first item of a new kind, in a list sorted by the kind.

The `update_header` can look at the current header widget using `gtk_list_box_row_get_header()` and either update the state of the widget as needed, or set a new one using `gtk_list_box_row_set_header()`. If no header is needed, set the header to `NULL`.

Note that you may get many calls `update_header` to this for a particular row when e.g. changing things that don’t affect the header. In this case it is important for performance to not blindly replace an existing header with an identical one.

The `update_header` function will be called for each row after the call, and it will continue to be called each time a row changes (via `gtk_list_box_row_changed()`) and when the row before changes (either by `gtk_list_box_row_changed()` on the previous row, or when the previous row becomes a different row). It is also called for all rows when `gtk_list_box_invalidate_headers()` is called.

#### Parameters

box | a GtkListBox |
update_header | callback that lets you add row headers. | [closure user_data][allow-none]
user_data | user data passed to `update_header` |
destroy | destroy notifier for `user_data` |

Since 3.10

### gtk_list_box_set_sort_func ()

    void
    gtk_list_box_set_sort_func (GtkListBox *box,
                                GtkListBoxSortFunc sort_func,
                                gpointer user_data,
                                GDestroyNotify destroy);

By setting a sort function on the `box` one can dynamically reorder the rows of the list, based on the contents of the rows.

The `sort_func` will be called for each row after the call, and will continue to be called each time a row changes (via `gtk_list_box_row_changed()`) and when `gtk_list_box_invalidate_sort()` is called.

#### Parameters

box | a GtkListBox |
sort_func | the sort function. | [closure user_data][allow-none]
user_data | user data passed to `sort_func` |
destroy | destroy notifier for `user_data` |

Since 3.10

### gtk_list_box_drag_highlight_row ()

    void
    gtk_list_box_drag_highlight_row (GtkListBox *box,
                                     GtkListBoxRow *row);

This is a helper function for implementing DnD onto a GtkListBox. The passed in `row` will be highlighted via `gtk_drag_highlight()`, and any previously highlighted row will be unhighlighted.

The row will also be unhighlighted when the widget gets a drag leave event.

#### Parameters

box | a GtkListBox |
row | a GtkListBoxRow |

Since 3.10

### gtk_list_box_drag_unhighlight_row ()

    void
    gtk_list_box_drag_unhighlight_row (GtkListBox *box);

If a row has previously been highlighted via `gtk_list_box_drag_highlight_row()` it will have the highlight removed.

#### Parameters

box | a GtkListBox |

Since 3.10

### GtkListBoxCreateWidgetFunc ()

    GtkWidget *
    (*GtkListBoxCreateWidgetFunc) (gpointer item,
                                   gpointer user_data);

Called for list boxes that are bound to a GListModel with `gtk_list_box_bind_model()` for each item that gets added to the model.

#### Parameters

item | the item from the model for which to create a widget for. | [type GObject]
user_data | user data. | [closure]

#### Returns

a GtkWidget that represents `item` .

[transfer full]

Since 3.16

### gtk_list_box_bind_model ()

    void
    gtk_list_box_bind_model (GtkListBox *box,
                             GListModel *model,
                             GtkListBoxCreateWidgetFunc create_widget_func,
                             gpointer user_data,
                             GDestroyNotify user_data_free_func);

Binds `model` to `box` .

If `box` was already bound to a model, that previous binding is destroyed.

The contents of `box` are cleared and then filled with widgets that represent items from `model` . `box` is updated whenever `model` changes. If `model` is `NULL`, `box` is left empty.

It is undefined to add or remove widgets directly (for example, with `gtk_list_box_insert()` or `gtk_container_add()`) while `box` is bound to a model.

#### Parameters

box | a GtkListBox |
model | the GListModel to be bound to `box` . | [allow-none]
create_widget_func | a function that creates widgets for items |
user_data | user data passed to `create_widget_func` |
user_data_free_func | function for freeing `user_data` |

Since 3.16

### gtk_list_box_row_new ()

    GtkWidget *
    gtk_list_box_row_new (void);

Creates a new GtkListBoxRow, to be used as a child of a GtkListBox.

#### Returns

a new GtkListBoxRow

Since 3.10

### gtk_list_box_row_changed ()

    void
    gtk_list_box_row_changed (GtkListBoxRow *row);

Marks `row` as changed, causing any state that depends on this to be updated. This affects sorting, filtering and headers.

Note that calls to this method must be in sync with the data used for the row functions. For instance, if the list is mirroring some external data set, and *two* rows changed in the external data set then when you call `gtk_list_box_row_changed()` on the first row the sort function must only read the new data for the first of the two changed rows, otherwise the resorting of the rows will be wrong.

This generally means that if you don’t fully control the data model you have to duplicate the data that affects the listbox row functions into the row widgets themselves. Another alternative is to call `gtk_list_box_invalidate_sort()` on any model change, but that is more expensive.

#### Parameters

row | a GtkListBoxRow |

Since 3.10

### gtk_list_box_row_is_selected ()

    gboolean
    gtk_list_box_row_is_selected (GtkListBoxRow *row);

Returns whether the child is currently selected in its GtkListBox container.

#### Parameters

row | a GtkListBoxRow |

#### Returns

`TRUE` if `row` is selected

Since 3.14

### gtk_list_box_row_get_header ()

    GtkWidget *
    gtk_list_box_row_get_header (GtkListBoxRow *row);

Returns the current header of the `row` . This can be used in a GtkListBoxUpdateHeaderFunc to see if there is a header set already, and if so to update the state of it.

#### Parameters

row | a GtkListBoxRow |

#### Returns

the current header, or `NULL` if none.

[transfer none]

Since 3.10

#### Parameters

row | a GtkListBoxRow |
header | the header, or `NULL`. | [allow-none]

Since 3.10

### gtk_list_box_row_get_index ()

Flags: Action

### The `“move-cursor”` signal

    void
    user_function (GtkListBox     *listbox,
                   GtkMovementStep arg1,
                   gint            arg2,
                   gpointer        user_data)

Flags: Action

### The `“row-activated”` signal

    void
    user_function (GtkListBox    *box,
                   GtkListBoxRow *row,
                   gpointer       user_data)
