Struct gtk4::Stack

source ·
pub struct Stack { /* private fields */ }
Expand description

Stack is a container which only shows one of its children at a time.

In contrast to Notebook, Stack does not provide a means for users to change the visible child. Instead, a separate widget such as StackSwitcher or StackSidebar can be used with Stack to provide this functionality.

Transitions between pages can be animated as slides or fades. This can be controlled with set_transition_type(). These animations respect the gtk-enable-animations setting.

Stack maintains a StackPage object for each added child, which holds additional per-child properties. You obtain the StackPage for a child with page() and you can obtain a SelectionModel containing all the pages with pages().

§GtkStack as GtkBuildable

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

  <object class="GtkStack" id="stack">
    <child>
      <object class="GtkStackPage">
        <property name="name">page1</property>
        <property name="title">In the beginning…</property>
        <property name="child">
          <object class="GtkLabel">
            <property name="label">It was dark</property>
          </object>
        </property>
      </object>
    </child>

§CSS nodes

Stack has a single CSS node named stack.

Stack uses the AccessibleRole::TabPanel for the stack pages, which are the accessible parent objects of the child widgets.
