desktop::notify::notification

Desktop::Notify::Notification(3pm)			User Contributed Perl Documentation			Desktop::Notify::Notification(3pm)

NAME

       Desktop::Notify::Notification - a notification object for the desktop notifications framework

VERSION

       Version 0.03

SYNOPSIS

	   # $notify is an existing Desktop::Notify object
	   my $note = $notify->create(summary => 'Rebuilding FooBar',
				      body => 'Progress: 10%');
	   $note->show;

	   ...

	   # Update the notification later
	   $note->body('Progress: 20%');
	   $note->show;

	   ...
	   # Take it off the screen
	   $note->close;

DESCRIPTION

       Desktop notification objects are represented as objects of this class.  They are created by a Desktop::Notify object.  Displaying, closing,
       and modifying the notification is done by using methods in this class.

METHODS

   new $notify, %params
       This is called internally by Desktop::Notify to create a new notification object.

   show
       Display the notification on the screen. If this notification had previously been shown and not closed yet, it will replace the existing
       notification.

       Show can be called multiple times on the same notification, probably with attribute changes between calls, and later show calls will cause
       the server to seamlessly replace the existing notification.

   close
       Close the notification if it is already being displayed.

ATTRIBUTES

       The following parameters can be set when creating the object or later modified using accessors (descriptions are from the specification at
       <http://www.galago-project.org/specs/notification/0.9/x408.html>)

       summary
	   The summary text briefly describing the notification.

       body
	   The optional detailed body text. Can be empty.

       timeout
	   The timeout time in milliseconds since the display of the notification at which the notification should automatically close.

	   If -1, the notification's expiration time is dependent on the notification server's settings, and may vary for the type of
	   notification. If 0, never expire.

       The following extra parameters are included in the specification but not supported by Desktop::Notify at this time

       app_icon
	   The optional program icon of the calling application.

       actions
	   Actions are sent over as a list of pairs. Each even element in the list (starting at index 0) represents the identifier for the action.
	   Each odd element in the list is the localized string that will be displayed to the user.

       hints
	   Optional hints that can be passed to the server from the client program.
