KDE Visual Design Group/HIG/Notification
Notifications are passive, they do not gain the focus, of events that happen in the background. E.g. arrival of new mails, incoming chat messages.
Is this the right control
- Use notifications to display information that does not require user action right away. E.g. don't use notifications for confirm changes. Use a Dialog if user interaction is required.
- Don't use notifications if your application might create them very often. Eg. Don't use a notification to show online / offline status of all contacts in a chat application
Notifications a shown for X seconds and then fade out. The user can see faded out notifications if she clicks on the notification icon in the system tray.
Notifications have a close icon and on configure icon on the top right
