//
// AdwNavigationView presents one child at a time, similar to gtk.Stack.
//
// AdwNavigationView can only contain navigationpage children.
//
// It maintains a navigation stack that can be controlled with
// navigationview.Push and navigationview.Pop. The whole navigation stack can
// also be replaced using navigationview.Replace.
//
// AdwNavigationView allows to manage pages statically or dynamically.
//
// Static pages can be added using the navigationview.Add method. The
// AdwNavigationView will keep a reference to these pages, but they aren't
// accessible to the user until navigationview.Push is called (except for the
// first page, which is pushed automatically). Use the navigationview.Remove
// method to remove them. This is useful for applications that have a small
// number of unique pages and just need navigation between them.
//
// Dynamic pages are automatically destroyed once they are popped off
// the navigation stack. To add a page like this, push it using the
// navigationview.Push method without calling navigationview.Add first.
//
// # Tags
//
// Static pages, as well as any pages in the navigation stack, can be accessed
// by their navigationpage:tag. For example, navigationview.PushByTag can be
// used to push a static page that's not in the navigation stack without having
// to keep a reference to it manually.
//
// # Header Bar Integration
//
// When used inside AdwNavigationView, headerbar will automatically display a
// back button that can be used to go back to the previous page when possible.
// The button also has a context menu, allowing to pop multiple pages at once,
// potentially across multiple navigation views.
//
// Set headerbar:show-back-button to FALSE to disable this behavior in rare
// scenarios where it's unwanted.
//
// AdwHeaderBar will also display the title of the AdwNavigationPage it's placed
// into, so most applications shouldn't need to customize it at all.
//
// # Shortcuts and Gestures
//
// AdwNavigationView supports the following shortcuts for going to the previous
// page:
//
// - <kbd>Escape</kbd> (unless navigationview:pop-on-escape is set to FALSE)
//
// - <kbd>Alt</kbd>+<kbd>←</kbd>
//
// - Back mouse button
//
// Additionally, it supports interactive gestures:
//
// - One-finger swipe towards the right on touchscreens
//
// - Scrolling towards the right on touchpads (usually two-finger swipe)
//
// These gestures have transitions enabled regardless of the
// navigationview:animate-transitions value.
//
// Applications can also enable shortcuts for pushing another page onto the
// navigation stack via connecting to the navigationview::get-next-page signal,
// in that case the following shortcuts are supported:
//
// - <kbd>Alt</kbd>+<kbd>→</kbd>
//
// - Forward mouse button
//
// - Swipe/scrolling towards the left
//
// For right-to-left locales, the gestures and shortcuts are reversed.
//
// navigationpage:can-pop can be used to disable them, along with the header bar
// back buttons.
//
// # Actions
//
// AdwNavigationView defines actions for controlling the navigation stack.
// actions for controlling the navigation stack:
//
// - navigation.push takes a string parameter specifying the tag of the page to
// push, and is equivalent to calling navigationview.PushByTag.
//
// - navigation.pop doesn't take any parameters and pops the current page from
// the navigation stack, equivalent to calling navigationview.Pop.
//
// # AdwNavigationView as GtkBuildable
//
// AdwNavigationView allows to add pages as children, equivalent to using the
// navigationview.Add method.
//
// Example of an AdwNavigationView UI definition:
//
//	<object class="AdwNavigationView">
//	  <child>
//	    <object class="AdwNavigationPage">
//	      <property name="title" translatable="yes">Page 1</property>
