Struct gio::Notification
source · #[repr(transparent)]pub struct Notification { /* private fields */ }
Expand description
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 Notification
and other similar APIs is
that, if supported by the desktop environment, notifications sent
with 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 Notification
should be able to be
started as a D-Bus service, using Application
.
In order for 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=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 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 ApplicationExt::send_notification()
.

Implementations§
source§impl Notification
impl Notification
sourcepub fn new(title: &str) -> Notification
pub fn new(title: &str) -> Notification
Creates a new Notification
with title
as its title.
After populating notification
with more details, it can be sent to
the desktop shell with ApplicationExt::send_notification()
. Changing
any properties after this call will not have any effect until
resending notification
.
title
the title of the notification
Returns
a new Notification
instance
Adds a button to self
that activates the action in
detailed_action
when clicked. That action must be an
application-wide action (starting with “app.”). If detailed_action
contains a target, the action will be activated with that target as
its parameter.
See Action::parse_detailed_name()
for a description of the format
for detailed_action
.
label
label of the button
detailed_action
a detailed action name
Adds a button to self
that activates action
when clicked.
action
must be an application-wide action (it must start with “app.”).
If target
is non-None
, action
will be activated with target
as
its parameter.
label
label of the button
action
an action name
target
a glib::Variant
to use as action
’s parameter, or None
sourcepub fn set_category(&self, category: Option<&str>)
Available on crate feature v2_70
only.
pub fn set_category(&self, category: Option<&str>)
v2_70
only.Sets the type of self
to category
. Categories have a main
type like email
, im
or device
and can have a detail separated
by a .
, e.g. im.received
or email.arrived
. Setting the category
helps the notification server to select proper feedback to the user.
Standard categories are listed in the specification.
category
the category for self
, or None
for no category
sourcepub fn set_default_action(&self, detailed_action: &str)
pub fn set_default_action(&self, detailed_action: &str)
Sets the default action of self
to detailed_action
. This
action is activated when the notification is clicked on.
The action in detailed_action
must be an application-wide action (it
must start with “app.”). If detailed_action
contains a target, the
given action will be activated with that target as its parameter.
See Action::parse_detailed_name()
for a description of the format
for detailed_action
.
When no default action is set, the application that the notification was sent on is activated.
detailed_action
a detailed action name
sourcepub fn set_default_action_and_target_value(
&self,
action: &str,
target: Option<&Variant>
)
pub fn set_default_action_and_target_value( &self, action: &str, target: Option<&Variant> )
Sets the default action of self
to action
. This action is
activated when the notification is clicked on. It must be an
application-wide action (start with “app.”).
If target
is non-None
, action
will be activated with target
as
its parameter.
When no default action is set, the application that the notification was sent on is activated.
action
an action name
target
a glib::Variant
to use as action
’s parameter, or None
sourcepub fn set_priority(&self, priority: NotificationPriority)
pub fn set_priority(&self, priority: NotificationPriority)
Sets the priority of self
to priority
. See
NotificationPriority
for possible values.
