qt-update-notifier is a community based project that seek to create a KDE technology based update notifier.
1.It waits for 24 hours before it automatically check for new updates.A user can do out of schedule checks anytime.The automatic check will then be done after 24 hours have passed since automatic or user initiated check.
2.After it is started up,it waits for 5 minutes before checking if 24 hours have passed since the last update.The delay is there to give time to users who may not network connection at log in like those who have to manually connect to wireless network first.
3 icons are used to identify 3 states the application may be in.
Greenish: No updates where found on the last check.
Blueish: In the process of checking for updates.
Reddish: Updates were found in the repository on the last check.
The application can be in two states,"passive" and "need attention".
The application will go to a "need attention" state when it found updates in the repository.KDE plasma will display the icon when it is in this state and will hide it when it is not.
The different icons are a primary way the application communicates its state with the user.
