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.

Details

NOTIFY_EXPIRES_DEFAULT

#define NOTIFY_EXPIRES_DEFAULT -1

The default expiration time on a notification.

NOTIFY_EXPIRES_NEVER

#define NOTIFY_EXPIRES_NEVER    0

The notification never expires. It stays open until closed by the calling API or the user.

NotifyNotification

typedef struct _NotifyNotification NotifyNotification;

This is an opaque structure representing a notification. This should not be used directly. Use the accessor functions below.

enum NotifyUrgency

typedef enum
{
        NOTIFY_URGENCY_LOW,
        NOTIFY_URGENCY_NORMAL,
        NOTIFY_URGENCY_CRITICAL,

} NotifyUrgency;

The urgency level of the notification.

NOTIFY_URGENCY_LOW

 Low urgency. Used for unimportant notifications.

NOTIFY_URGENCY_NORMAL

 Normal urgency. Used for most standard notifications.

NOTIFY_URGENCY_CRITICAL

 Critical urgency. Used for very important notifications.
