ViewSwitcherBar

class ViewSwitcherBar(pointer: <Error class: unknown class><<Error class: unknown class>>)

A view switcher action bar.

An action bar letting you switch between multiple views contained in a class@ViewStack, via an class@ViewSwitcher. It is designed to be put at the bottom of a window and to be revealed only on really narrow windows, e.g. on mobile phones. It can't be revealed if there are less than two pages.

AdwViewSwitcherBar is intended to be used together with AdwViewSwitcher in a header bar, and a class@Breakpoint showing the view switcher bar on narrow sizes, while removing the view switcher from the header bar, as follows:

<object class="AdwWindow">
  <child>
    <object class="AdwBreakpoint">
      <condition>max-width: 550sp</condition>
      <setter object="switcher_bar" property="reveal">True</setter>
      <setter object="header_bar" property="title-widget"/>
    </object>
  </child>
  <property name="content">
    <object class="AdwToolbarView">
      <child type="top">
        <object class="AdwHeaderBar" id="header_bar">
