\brief A class that represents a modeless notification banner.
\ingroup views
\section MInfoBannerEventViewOverview Overview
- An event banner is a modeless notification banner that appears on screen on top of the given UI
(all but in certain exception cases, like full screen video playback).
- An event banner is used for events that should be persistent: i.e. if the user does not click on
the event banner when it is shown, they will be shown on the Home screen.
- The banner disappears from the screen after a timeout, after the timeout the incoming event can
be found from the Home view.
- The event banner has an action associated to it: usually tapping the notification opens the item
in a new task.
- If the application view where a new event occurs is in the foreground, no extra notification
should displayed, the update should be shown directly in the foreground UI.
- If there is several information updates happening at the same time the incoming event banners should
be shown one after another.
- The event banners should not overlap the virtual keyboard: if the VKB is
open, the preview should be positioned above the keyboard.
- Event banners have (currently) a fixed size.
