## 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.

### NotifyActionCallback ()

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

An action callback function.

`notification` : |
`action` : |
`user_data` : |

### 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()`.

`func` : | The function to cast.

### notify_notification_new ()

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

`summary` : | The required summary text.
`body` : | The optional body text.
`icon` : | The optional icon theme icon name or filename.
`attach` : | The optional widget to attach to.
Returns : | The new NotifyNotification.

### notify_notification_new_with_status_icon ()

    NotifyNotification * notify_notification_new_with_status_icon
                                                            (const char *summary,
                                                             const char *body,

`summary` : | The required summary text.
`body` : | The optional body text.
`icon` : | The optional icon theme icon name or filename.
`status_icon` : | The required GtkStatusIcon.
Returns : | The new NotifyNotification.

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()`.

`notification` : | The notification to update.
`summary` : | The new required summary text.
`body` : | The optional body text.
`icon` : | The optional icon theme icon name or filename.
Returns : | `TRUE`, unless an invalid parameter was passed.

Attaches the notification to a GtkStatusIcon. This will set hints on the notification requesting that the notification point to the status icon's location. If `status_icon` is `NULL`, the status icon will be unset.

`notification` : | The notification.
`status_icon` : | The GtkStatusIcon to attach to, or `NULL`.

### Warning

`notify_notification_set_icon_from_pixbuf` is deprecated and should not be used in newly-written code. use `notify_notification_set_image_from_pixbuf()` instead.
