Adw.NavigationPage – libadwaita-1 – Vala Binding Reference

Description:

[ CCode ( type_id = "adw_navigation_page_get_type ()" ) ]
[ Version ( since = "1.4" ) ]
public class NavigationPage : Widget, Accessible, Buildable, ConstraintTarget

A page within [class@NavigationView] or [class@NavigationSplitView].

Each page has a child widget, a title and optionally a tag.

The [signal@NavigationPage:AdwNavigationPage:showing], [signal@NavigationPage:AdwNavigationPage:shown], [ signal@NavigationPage:AdwNavigationPage:hiding] and [signal@NavigationPage:AdwNavigationPage:hidden] signals can be used to track the page's visibility within its `AdwNavigationView`.

Header Bar Integration

When placed inside `AdwNavigationPage`, [class@HeaderBar] will display the page title instead of window title.

When used together with [class@NavigationView], it will also display a back button that can be used to go back to the previous page. Set [property@HeaderBar:show-back-button] to `FALSE` to disable that behavior if it's unwanted.
