Struct gtk4::ListView

#[repr(transparent)]
pub struct ListView { /* private fields */ }

ListView presents a large dynamic list of items.

ListView uses its factory to generate one row widget for each visible item and shows them in a linear display, either vertically or horizontally.

The show-separators property offers a simple way to display separators between the rows.

ListView allows the user to select items according to the selection characteristics of the model. For models that allow multiple selected items, it is possible to turn on rubberband selection, using enable-rubberband.

If you need multiple columns with headers, see ColumnView.

To learn more about the list widget framework, see the overview.

An example of using ListView: ⚠️ The following code is in c ⚠️

static void
setup_listitem_cb (GtkListItemFactory *factory,
                   GtkListItem        *list_item)
{
  GtkWidget *image;

  image = gtk_image_new ();
  gtk_image_set_icon_size (GTK_IMAGE (image), GTK_ICON_SIZE_LARGE);
  gtk_list_item_set_child (list_item, image);
}

static void
bind_listitem_cb (GtkListItemFactory *factory,
                  GtkListItem        *list_item)
{
  GtkWidget *image;
  GAppInfo *app_info;

  image = gtk_list_item_get_child (list_item);
  app_info = gtk_list_item_get_item (list_item);
  gtk_image_set_from_gicon (GTK_IMAGE (image), g_app_info_get_icon (app_info));
}

static void
activate_cb (GtkListView  *list,
             guint         position,
             gpointer      unused)
{
  GAppInfo *app_info;

  app_info = g_list_model_get_item (G_LIST_MODEL (gtk_list_view_get_model (list)), position);
  g_app_info_launch (app_info, NULL, NULL, NULL);
  g_object_unref (app_info);
}

...

  model = create_application_list ();

  factory = gtk_signal_list_item_factory_new ();
  g_signal_connect (factory, "setup", G_CALLBACK (setup_listitem_cb), NULL);
  g_signal_connect (factory, "bind", G_CALLBACK (bind_listitem_cb), NULL);

  list = gtk_list_view_new (GTK_SELECTION_MODEL (gtk_single_selection_new (model)), factory);

  g_signal_connect (list, "activate", G_CALLBACK (activate_cb), NULL);

  gtk_scrolled_window_set_child (GTK_SCROLLED_WINDOW (sw), list);

ListView uses a single CSS node named listview. It may carry the .separators style class, when show-separators property is set. Each child widget uses a single CSS node named row. If the activatable property is set, the corresponding row will have the .activatable style class. For rubberband selection, a node with name rubberband is used.

The main listview node may also carry style classes to select the style of list presentation: .rich-list, .navigation-sidebar or .data-table.

Accessibility

ListView uses the AccessibleRole::List role, and the list items use the AccessibleRole::ListItem role.

Signals

activate

Emitted when a row has been activated by the user, usually via activating the GtkListView|list.activate-item action.

This allows for a convenient way to handle activation in a listview. See ListItem::set_activatable() for details on how to use this signal.

Widget

destroy

Signals that all holders of a reference to the widget should release the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

direction-changed

Emitted when the text direction of a widget changes.

hide

Emitted when @widget is hidden.

keynav-failed

Emitted if keyboard navigation fails.

See WidgetExt::keynav_failed() for details.

map

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with visible) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of unmap.

mnemonic-activate

Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates @widget if @group_cycling is false, or just makes @widget grab focus if @group_cycling is true.

move-focus

Emitted when the focus is moved.

Action

query-tooltip

Emitted when the widgets tooltip is about to be shown.

This happens when the has-tooltip property is true and the hover timeout has expired with the cursor hovering “above” @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for @widget. If this is the case true should be returned, false otherwise. Note that if @keyboard_mode is true, the values of @x and @y are undefined and should not be used.

The signal handler is free to manipulate @tooltip with the therefore destined function calls.

realize

Emitted when @widget is associated with a gdk::Surface.

This means that WidgetExt::realize() has been called or the widget has been mapped (that is, it is going to be drawn).

show

Emitted when @widget is shown.

state-flags-changed

Emitted when the widget state changes.

See WidgetExt::state_flags().

unmap

Emitted when @widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

unrealize

Emitted when the gdk::Surface associated with @widget is destroyed.

This means that WidgetExt::unrealize() has been called or the widget has been unmapped (that is, it is going to be hidden).
