| == 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 using [[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 using a [[Projects/Usability/HIG/MessageDialog|message dialog]].
| |
| * Do not add controls to notification.
| |
| * Do not override system settings.
| |
| * Provide title and content text.
| |
| * 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.
| |
| * 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.")
