Detailed Description

User Notifications (pop up messages).

Gio::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 Gio::Application.

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::send_notification().

Member Function Documentation

void Gio::Notification::add_button	(	const Glib::ustring&	label,
		const Glib::ustring&	detailed_action
	)

Adds a button to notification 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 g_action_parse_detailed_name() for a description of the format for detailed_action.

Since glibmm 2.40:

Parameters

label	Label of the button.
detailed_action	A detailed action name.

template <typename T_Value >

void Gio::Notification::add_button	(	const Glib::ustring&	label,
		const Glib::ustring&	action,
		const T_Value &	target
	)

Adds a button that activates action when clicked.

action must be an application-wide action (it must start with "app."). action will be activated with target as its parameter.

Since glibmm 2.40:

Parameters

label	Label of the button.
action	An action name.
target	action's parameter.

void Gio::Notification::add_button_variant	(	const Glib::ustring&	label,
		const Glib::ustring&	action,
		const Glib::VariantBase&	target
	)

Adds a button to notification that activates action when clicked.

action must be an application-wide action (it must start with "app.").

If target is non-nullptr, action will be activated with target as its parameter.

Since glibmm 2.40:

Parameters

label	Label of the button.
action	An action name.
target	A Variant to use as action's parameter, or `nullptr`.

static Glib::RefPtr<Notification> Gio::Notification::create ( const Glib::ustring& title )

static

Creates a new Notification with title as its title.

After populating notification with more details, it can be sent to the desktop shell with g_application_send_notification(). Changing any properties after this call will not have any effect until resending notification.

Since glibmm 2.40:

Parameters

title The title of the notification.

Returns: A new Notification instance.

static GType Gio::Notification::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

GNotification* Gio::Notification::gobj ( )

inline

Provides access to the underlying C GObject.

const GNotification* Gio::Notification::gobj ( ) const

inline

Provides access to the underlying C GObject.

GNotification* Gio::Notification::gobj_copy ( )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

Notification& Gio::Notification::operator= ( Notification&& src )

noexcept

void Gio::Notification::set_body ( const Glib::ustring& body )

Sets the body of notification to body.

Since glibmm 2.40:

Parameters

body	The new body for notification, or `nullptr`.

void Gio::Notification::set_default_action ( const Glib::ustring& detailed_action )

Sets the default action of notification 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 g_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.

Since glibmm 2.40:

Parameters

detailed_action A detailed action name.

template <typename T_Value >

void Gio::Notification::set_default_action	(	const Glib::ustring&	action,
		const T_Value &	target
	)

Sets the default action to action.

This action is activated when the notification is clicked on. It must be an application-wide action (start with "app."). 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.

Since glibmm 2.40:

Parameters

action	An action name.
target	action's parameter.

void Gio::Notification::set_default_action_variant	(	const Glib::ustring&	action,
		const Glib::VariantBase&	target
	)

Sets the default action of notification 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-nullptr, 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.

Since glibmm 2.40:

Parameters

action	An action name.
target	A Variant to use as action's parameter, or `nullptr`.

void Gio::Notification::set_icon ( const Glib::RefPtr< Icon >& icon )

Sets the icon of notification to icon.

Since glibmm 2.40:

Parameters

icon	The icon to be shown in notification, as a Icon.

void Gio::Notification::set_priority ( Priority priority = Priority::NORMAL )

Sets the priority of notification to priority.

See Gio::Notification::Priority for possible values.

Since glibmm 2.44:

Parameters

priority A Gio::Notification::Priority.

void Gio::Notification::set_title ( const Glib::ustring& title )

Sets the title of notification to title.

Since glibmm 2.40:

Parameters

title The new title for notification.

Glib::RefPtr< Gio::Notification > wrap	(	GNotification *	object,
		bool	take_copy = `false`
	)

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns: A C++ instance that wraps this C instance.
