Class
AdwNavigationView
since: 1.4
Description [src]
final class Adw.NavigationView : Gtk.Widget
implements Adw.Swipeable, Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget {
/* No available fields */
}
A page-based navigation container.
AdwNavigationView
presents one child at a time, similar to
GtkStack
.
AdwNavigationView
can only contain AdwNavigationPage
children.
It maintains a navigation stack that can be controlled with
adw_navigation_view_push()
and adw_navigation_view_pop()
. The whole
navigation stack can also be replaced using adw_navigation_view_replace()
.
AdwNavigationView
allows to manage pages statically or dynamically.
Static pages can be added using the adw_navigation_view_add()
method. The
AdwNavigationView
will keep a reference to these pages, but they aren’t
accessible to the user until adw_navigation_view_push()
is called (except
for the first page, which is pushed automatically). Use the
adw_navigation_view_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
adw_navigation_view_push()
method without calling
adw_navigation_view_add()
first.
Tags
Static pages, as well as any pages in the navigation stack, can be accessed
by their AdwNavigationPage:tag
. For example,
adw_navigation_view_push_by_tag()
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
, AdwHeaderBar
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 AdwHeaderBar:show-back-button
to FALSE
to disable this behavior
if 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:
- Escape (unless
AdwNavigationView:pop-on-escape
is set toFALSE
) - Alt+←
- 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
AdwNavigationView:animate-transitions
value.
Applications can also enable shortcuts for pushing another page onto the
navigation stack via connecting to the AdwNavigationView::get-next-page
signal, in that case the following shortcuts are supported:
- Alt+→
- Forward mouse button
- Swipe/scrolling towards the left
For right-to-left locales, the gestures and shortcuts are reversed.
AdwNavigationPage: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 callingadw_navigation_view_push_by_tag()
. -
navigation.pop
doesn’t take any parameters and pops the current page from the navigation stack, equivalent to callingadw_navigation_view_pop()
.
AdwNavigationView
as GtkBuildable
AdwNavigationView
allows to add pages as children, equivalent to using the
adw_navigation_view_add()
method.
