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.

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.

Since: 3.10

gtk_list_box_invalidate_sort ()

void
gtk_list_box_invalidate_sort (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.

Note that using a filter function is incompatible with using a model (see gtk_list_box_bind_model()).

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.

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.

Note that using a sort function is incompatible with using a model (see gtk_list_box_bind_model()).

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.

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.

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.

Versions of GTK+ prior to 3.18 called gtk_widget_show_all() on the rows created by the GtkListBoxCreateWidgetFunc, but this forced all widgets inside the row to be shown, and is no longer the case. Applications should be updated to show the desired row widgets.

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.

Note that using a model is incompatible with the filtering and sorting functionality in GtkListBox. When using a model, filtering and sorting should be implemented by the model.

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.

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.

Since: 3.10

gtk_list_box_row_is_selected ()

gboolean
gtk_list_box_row_is_selected (GtkListBoxRow *row);

void
gtk_list_box_row_set_header (GtkListBoxRow *row,
                             GtkWidget *header);
