Description

NotifyNotification represents a passive pop-up notification. It can contain summary text, body text, and an icon, as well as hints specifying how the notification should be presented. The notification is rendered by a notification daemon, and may present the notification in any number of ways. As such, there is a clear separation of content and presentation, and this API enforces that.

Functions

NotifyActionCallback ()

void
(*NotifyActionCallback) (NotifyNotification *notification,
                         char *action,
                         gpointer user_data);

An action callback function.

NOTIFY_ACTION_CALLBACK()

#define NOTIFY_ACTION_CALLBACK(func) ((NotifyActionCallback)(func))

A convenience macro for casting a function to a NotifyActionCallback. This is much like G_CALLBACK().

Parameters

func

The function to cast.

notify_notification_new ()

NotifyNotification *
notify_notification_new (const char *summary,
                         const char *body,
                         const char *icon);

Creates a new NotifyNotification. The summary text is required, but all other parameters are optional.

Parameters

summary	The required summary text.
body	The optional body text.	[allow-none]
icon	The optional icon theme icon name or filename.	[allow-none]

Returns

The new NotifyNotification.

notify_notification_update ()

gboolean
notify_notification_update (NotifyNotification *notification,
                            const char *summary,
                            const char *body,
                            const char *icon);

Updates the notification text and icon. This won't send the update out and display it on the screen. For that, you will need to call notify_notification_show().

Parameters

notification	The notification to update.
summary	The new required summary text.
body	The optional body text.	[allow-none]
icon	The optional icon theme icon name or filename.	[allow-none]

Tells the notification server to display the notification on the screen.

Parameters

notification	The notification.
error	The returned error information.

Returns

TRUE if successful. On error, this will return FALSE and set error .

                                  const char *app_name);

Sets the application name for the notification. If this function is not called or if app_name is NULL, the application name will be set from the value used in notify_init() or overridden with notify_set_app_name().

Parameters
