Description: Reference for Gtk.ListBox

### Class

# GtkListBox

#### Description [src]

    final class Gtk.ListBox : Gtk.Widget
      implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget {
      /* No available fields */
    }

`GtkListBox` is a vertical list.

A `GtkListBox` only 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_list_box_prepend()`, `gtk_list_box_append()` and `gtk_list_box_insert()` 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, `GtkListBox::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.

# GtkListBox as GtkBuildable

The `GtkListBox` implementation of the `GtkBuildable` interface supports setting a child as the placeholder by specifying “placeholder” as the “type” attribute of a `<child>` element. See `gtk_list_box_set_placeholder()` for info.

# Shortcuts and Gestures

The following signals have default keybindings:

- `GtkListBox::move-cursor`
- `GtkListBox::select-all`
- `GtkListBox::toggle-cursor-row`
- `GtkListBox::unselect-all`

# CSS nodes

    list[.separators][.rich-list][.navigation-sidebar][.boxed-list]
    ╰── row[.activatable]

`GtkListBox` uses a single CSS node named list. It may carry the .separators style class, when the `GtkListBox:show-separators` property is set. Each `GtkListBoxRow` uses a single CSS node named row. The row nodes get the .activatable style class added when appropriate.

It may also carry the .boxed-list style class. In this case, the list will be automatically surrounded by a frame and have separators.

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

# Accessibility

`GtkListBox` uses the `GTK_ACCESSIBLE_ROLE_LIST` role and `GtkListBoxRow` uses the `GTK_ACCESSIBLE_ROLE_LIST_ITEM` role.
