| __NOTOC__
| | {{ Moved To Community | KDE_Visual_Design_Group/HIG/Notifications }} |
| 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>
| |
| * Add origin and topic to the title. For instance: "Amarok: Now playing" or "Konsole: Event"
| |
| * Keep the notification content concise (no more than about three simple sentences).<span style="color:blue">Thomas: See David's comments in his mail</span>
| |
| * Customize notification with the origin's icon. (remark: word "origin" needs to be replaced; "icon" might be replaced by technical term)
| |
| * 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.") (remark: should be according actual text)
| |
| to be defined: Are all notifications configured in KCM? If not, how to separate?
