back to [[Projects/Usability/HIG|Human Interface Guidelines]]
 
== Purpose ==
 
A ''notification'' is an information that is not directly relevant to the user's current task. It is displayed via a certain [[Projects/Usability/HIG/NotificationMechanism|notification mechanism]] on a panel above/below the taskbar notification area. Notifications inform users about non-critical problems, but they don't prevent them.
 
 
 
Notifications pop up and overlay all other windows. Multiple notifications are stacked vertically. Notifications disappear after a short period automatically (unless the cursor hovers over them), but can be closed by the user at any point. Each notification has its own [[Projects/Usability/HIG/CentralConfiguration|central configuration]] which can be reached by a button next to the close button.
 
== Examples ==
 
(remark: pictures only?)
 
=== Positive ===
 
* Email received
 
* New update available
 
* Download completed
 
* Low battery power
 
todo: picture
 
=== Negative ===
 
* Low space on medium (this information becomes relevant for file managers and invoked as modal message in this case)
 
todo: picture
 
== Guidelines ==
 
* Do not use notifications for user assistance (consider to use [[Projects/Usability/HIG/Tooltip|tool-tips]] or [[Projects/Usability/HIG/Balloon|balloons]] 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/MessageDialog|message dialog]].
 
* Do not add controls to notification. <span style="color:blue">Thomas: I would remove this. Adding action buttons is allowed in the API and has reasonable use cases, other controls simply cannot be added technically)</span>
 
* Do not override system settings. (remark: more specific)  <span style="color:blue">Thomas: Which settings do you mean here?</span>
 
* Provide title and content text (remark: not precise enough) <span style="color:blue">Thomas: guidelines regarding the wording of title and content are indeed very important. Maybe celeste can help here.</span>
 
* 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).
 
* Customize notification with the origin's icon.  <span style="color:blue">Heiko: (remark: word "origin" needs to be replaced; "icon" might be replaced by technical term) </span>
 
* Provide actionable information (e.g. "Low battery power" "Only 13 min (2%) capacity remaining. Please save your stuff now. Your system will get shut down soon.") <span style="color:blue">Heiko: (remark: should be according actual text)</span>
 
* <span style="color:blue">Heiko: to be defined: Are all notifications configured in KCM? If not, how to separate?</span>
