hi folks,
I have a concerns on how MeeGo is alerting user.
In System UI (MeeGoTouch) there is a pop up notifications system.
These notifications cannot interact with user , they are simply
notifying events to user
In embedded systems, e.g a Phone device we do need to notify user with
interactive notifications e.g for an incoming call, a pin code dialog,
an appointment notification and so on.
the main aspects of these interactive notification are:
1 - they interact with user
2 - they pop over any ongoing activities.
3 - there have priorities : an incoming call notification has to preempt
an appointment interactive notification
usually to achieve that, we need systems components to manage
1 - z-ordering of windows,
2 - sharing screen access with priorities (to manage concurrent access)
3 - a component to manage user interactive notification - let's call it
an Attention Manager (this was an old PalmOS name for this)
Is there a system component that is handling z -ordering within MeeGo?
Is there a system component that is managing access to resources (screen
, sounds etc...) within user interaction context within MeeGo?
Is there a system component that is managing user interactive
notifications within MeeGo?
To manage resources access, I saw there is the Policy Resources Manager
, but it seems more sound, video, multimedia orientated, even if its
documentation is sometimes referring about sharing user interfaces.
Does this Policy manager is the component with which we should try to
manage screen concurrent access?
In Meego Touch Framework mCompositor is there to deal with windows.
Is mCompositor managing windows z-ordering?
As it seems to be a framework component and not a system component what
happens with non MTF application like QtQuick/QT apps?
Cordially,
Paul
