ListView#

class ListView(**properties: Any)#

Superclasses: ListBase, Widget, InitiallyUnowned, Object

Implemented Interfaces: Accessible, Buildable, ConstraintTarget, Orientable, Scrollable

Presents a large dynamic list of items.

GtkListView 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.

GtkListView 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 GtkListView:

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);

Actions#

GtkListView defines a set of built-in actions:

list.activate-item activates the item at given position by emitting the activate signal.

CSS nodes#

listview[.separators][.rich-list][.navigation-sidebar][.data-table]
├── row[.activatable]
│
├── row[.activatable]
│
┊
╰── [rubberband]

GtkListView 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#

GtkListView uses the list role, and the list items use the list_item role.

Constructors#

class ListView

classmethod new(model: SelectionModel | None = None, factory: ListItemFactory | None = None) → Widget#

Creates a new GtkListView that uses the given factory for mapping items to widgets.

The function takes ownership of the arguments, so you can write code like

list_view = gtk_list_view_new (create_model (),
  gtk_builder_list_item_factory_new_from_resource ("/resource.ui"));

Parameters:

model – the model to use
factory – The factory to populate items with

Methods#

class ListView

get_enable_rubberband() → bool#: Returns whether rows can be selected by dragging with the mouse.

get_factory() → ListItemFactory | None#: Gets the factory that’s currently used to populate list items.

get_header_factory() → ListItemFactory | None#: Gets the factory that’s currently used to populate section headers.

Added in version 4.12.

get_model() → SelectionModel | None#: Gets the model that’s currently used to read the items displayed.

get_show_separators() → bool#: Returns whether the listview should show separators between rows.

get_single_click_activate() → bool#: Returns whether rows will be activated on single click and selected on hover.

get_tab_behavior() → ListTabBehavior#: Gets the behavior set for the Tab key.

Added in version 4.12.

scroll_to(pos: int, flags: ListScrollFlags, scroll: ScrollInfo | None = None) → None#

Scrolls to the item at the given position and performs the actions specified in flags.

This function works no matter if the listview is shown or focused. If it isn’t, then the changes will take effect once that happens.

Added in version 4.12.

Parameters:

pos – position of the item. Must be less than the number of items in the view.
flags – actions to perform
scroll – details of how to perform the scroll operation or None to scroll into view

set_enable_rubberband(enable_rubberband: bool) → None#

Sets whether selections can be changed by dragging with the mouse.

Parameters:: enable_rubberband – whether to enable rubberband selection

set_factory(factory: ListItemFactory | None = None) → None#

Sets the GtkListItemFactory to use for populating list items.

Parameters:: factory – the factory to use

set_header_factory(factory: ListItemFactory | None = None) → None#

Sets the GtkListItemFactory to use for populating the ListHeader objects used in section headers.

If this factory is set to NULL, the list will not show section headers.

Added in version 4.12.

Parameters:: factory – the factory to use

set_model(model: SelectionModel | None = None) → None#

Sets the model to use.

This must be a SelectionModel to use.

Parameters:: model – the model to use

set_show_separators(show_separators: bool) → None#

Sets whether the listview should show separators between rows.

Parameters:: show_separators – whether to show separators

set_single_click_activate(single_click_activate: bool) → None#

Sets whether rows should be activated on single click and selected on hover.

Parameters:: single_click_activate – whether to activate items on single click

set_tab_behavior(tab_behavior: ListTabBehavior) → None#

Sets the Tab key behavior.

This influences how the Tab and Shift+:kbd:Tab keys move the focus in the listview.

Added in version 4.12.

Parameters:: tab_behavior – The desired tab behavior

Signals#

class ListView.signals

activate(position: int) → None#

Emitted when a row has been activated by the user.

Activation usually happens via the list.activate-item action of the GtkListView.

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