## Description

A GtkStackSidebar enables you to quickly and easily provide a consistent "sidebar" object for your user interface.

In order to use a GtkStackSidebar, you simply use a GtkStack to organize your UI flow, and add the sidebar to your sidebar area. You can use `gtk_stack_sidebar_set_stack()` to connect the GtkStackSidebar to the GtkStack.

When circumstances require it, GtkStackSidebar adds the .needs-attention style class to the widgets representing the stack pages.
