### Class

# Adw ViewStack

#### Description [src]

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

A view container for `AdwViewSwitcher`.

`AdwViewStack` is a container which only shows one page at a time. It is typically used to hold an application’s main views.

It doesn’t provide a way to transition between pages. Instead, a separate widget such as `AdwViewSwitcher`, `AdwInlineViewSwitcher` or `AdwViewSwitcherSidebar` can be used with `AdwViewStack` to provide this functionality.

`AdwViewStack` pages can have a title, an icon, an attention request, and a numbered badge that `AdwViewSwitcher` will use to let users identify which page is which. Set them using the `AdwViewStackPage:title`, `AdwViewStackPage:icon-name`, `AdwViewStackPage:needs-attention`, and `AdwViewStackPage:badge-number` properties.

`AdwViewStack` pages can also be grouped into sections, using the `AdwViewStackPage:starts-section` and `AdwViewStackPage:section-title` properties. Currently, only `AdwViewSwitcherSidebar` displays groups.

Unlike `GtkStack`, transitions between views can only be animated via a crossfade and size changes are always interpolated. Animations are disabled by default. Use `AdwViewStack:enable-transitions` to enable them.

`AdwViewStack` maintains a `AdwViewStackPage` object for each added child, which holds additional per-child properties. You obtain the `AdwViewStackPage` for a child with `adw_view_stack_get_page()` and you can obtain a `GtkSelectionModel` containing all the pages with `adw_view_stack_get_pages()`.

## AdwViewStack as GtkBuildable

To set child-specific properties in a .ui file, create `AdwViewStackPage` objects explicitly, and set the child widget as a property on it:

      <object class="AdwViewStack" id="stack">
        <child>
          <object class="AdwViewStackPage">
            <property name="name">overview</property>
            <property name="title">Overview</property>
            <property name="child">
              <object class="AdwStatusPage">
                <property name="title">Welcome!</property>
              </object>
            </property>
          </object>
        </child>
      </object>

## CSS nodes

`AdwViewStack` has a single CSS node named `stack`.

## Accessibility

`AdwViewStack` uses the `GTK_ACCESSIBLE_ROLE_TAB_PANEL` for the stack pages which are the accessible parent objects of the child widgets.
