[kde-guidelines] Styleguide: Notifications (Was: KStyleguide)

[Heiko Tietze]

I applied the new structure and removed questionable items.

User Assistance > System triggered notification
* Use a notification as system-triggered message to acknowledge about events out of the current context.

http://techbase.kde.org/Projects/Usability/HIG/Notifications

== Purpose ==
A ''notification'' is an information that is not directly relevant to the user's current task. It is displayed via a certain notification mechanism on a panel above/below the taskbar notification area. Notifications inform users about non-critical problems, but they don't prevent them.

== Examples ==

== Guidelines ==
=== Is this the right control ===
* Use a notification to inform about a non-critical problem that is not directly relevant to the user's current task. 
* Do not use notifications for user assistance (consider to use [[Projects/Usability/HIG/Tooltip|tool-tips]] for short information, or refer to [[Projects/Usability/HIG/HelpSystem|help system]] for extended text).
* Do not use notifications for context relevant information that might interfere with the actual workflow (consider to use a [[Projects/Usability/HIG/Messages|message dialog]]).

=== Behavior ===
* Notifications disappear after a short period automatically (unless the cursor hovers over them), but can be closed by the user at any point. 
* Stack multiple notifications vertically.
* Provide access to the configuration for each notification per button next to the close button.

=== Appearance ===
* Make sure to make the origin of the notification clear from the notification title. For instance: "Amarok: Now playing" or "Konsole: Event".
* Keep the notification content concise (no more than about three simple sentences).
* Provide actionable information (e.g. "Low battery power: Approximately 13 min (2%) capacity remaining.").

== Implementation ==
