Description: Reference for Gtk.ListBox

### Class

# GtkListBox

#### Description [src]

    final class Gtk.ListBox : Gtk.Widget {
      /* 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 element. See `gtk_list_box_set_placeholder()` for info.

# CSS nodes

    list[.separators][.rich-list][.navigation-sidebar]
    ╰── 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.

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.
