Notification

open class Notification(pointer: <Error class: unknown class><<Error class: unknown class>>)

#GNotification 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 #GNotification and other similar APIs is that, if supported by the desktop environment, notifications sent with #GNotification 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 #GNotification should be able to be started as a D-Bus service, using #GApplication.

In order for #GNotification 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=true ]|

The 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 g_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 g_application_send_notification().
