gio.notification
Module for [Notification] class
Types 3
[gio.notification.Notification] is a mechanism for creating a notification to be shown to the user — typically as a pop-up notification presented by the desktop environment shell.
The key difference between [gio.notification.Notification] and other similar APIs is that, if supported by the desktop environment, notifications sent with [gio.notification.Notification] will persist after the application has exited, and even across system reboots.
Since the user may click on a notification while the application is not running, applications using [gio.notification.Notification] should be able to be started as a D-Bus service, using [gio.application.Application].
In order for [gio.notification.Notification] to work, the application must have installed a .desktop file. For example:
[Desktop Entry]
Name=Test Application
Comment=Description of what Test Application does
Exec=gnome-test-application
Icon=org.gnome.TestApplication
Terminal=false
Type=Application
Categories=GNOME;GTK;TestApplication Category;
StartupNotify=true
DBusActivatable=true
X-GNOME-UsesNotifications=trueThe X-GNOME-UsesNotifications key indicates to GNOME Control Center that this application uses notifications, so it can be listed in the Control Center’s ‘Notifications’ panel.
The .desktop file must be named as org.gnome.TestApplication.desktop, where org.gnome.TestApplication is the ID passed to [gio.application.Application.new_].
User interaction with a notification (either the default action, or buttons) must be associated with actions on the application (ie: app. actions). It is not possible to route user interaction through the notification itself, because the object will not exist if the application is autostarted as a result of a notification being clicked.
A notification can be sent with [gio.application.Application.sendNotification].
