7. Introduction KDE Mobile Plasma Mobile
The Plasma Project
An ionized gaz...
The beginning...
Design started somehow in 2006
First code was written in 2007
Came as a replacement of KDE3 technologies :
KDesktop, Karamba and Kicker
Released in KDE 4.0 (January 2008)

8. Introduction KDE Mobile Plasma Mobile
The Plasma Project
A long start...
The beginning...
First release was missing many features but add new
capabilities
Many KDE3 features were added during 4.1, 4.2, 4.3 and
4.4
Last release is KDE 4.4.1 two weeks ago

9. Introduction KDE Mobile Plasma Mobile
The Plasma Project
Plasma Everywhere...
Plasma today
A desktop user interface that will mature in 4.5
A netbook interface released with KDE 4.4 which will be
completed in 4.5
An upcoming interface for mobile phones

KDE on a phone, WTF? (1/4)
Well, we have Qt on phones now
KDE Today
Around 48 Mb on disk to use the full platform
Rumors says that on MeeGo 3rd party apps will have
32Mb
Kdelibs is one big beast

14. Introduction KDE Mobile Plasma Mobile

Solving the puzzle...
The strategy
Reduce KDE platform internal dependencies
Modular packaging so you install what you need
No Binary division like Full Desktop/Mobile phone
Alexis Menard — KDE Plasma for Mobile Phones 14/32

15. Introduction KDE Mobile Plasma Mobile
KDE on a phone, WTF? (3/4)
Let’s have a look on the menu...
Three profiles...
KDE Desktop : what we know today
KDE Tablet : mostly the full game aiming for very low
feature loss, but some modules aren’t recommended
KDE Mobile : only the most useful modules.
Dependencies are simplified as much as possible, useful
modules are marked as mobile suitable
Alexis Menard — KDE Plasma for Mobile Phones 15/32

16. Introduction KDE Mobile Plasma Mobile
KDE on a phone, WTF? (4/4)
The plan...
Action plan
We need to communicate with packagers in order to see
more fine graine packages built, at least for the
non-desktop variant of distros.
We need to add a CMake option to build KDE for a given
profile
Don’t enforce the KStyle on other platforms
The Mobile platform comes with much more constrains
and there are no kdelibs yet there, so no compatibility can
be broken. We might do some BC breakage here to allow
slimmer dependencies

The project
KDE strikes back...
Plasma Mobile
Some research has happened in Maemo Summit when
some people got a N900
Extra research on a complete Plasma in
November/December 2009
We officially kicked the project in February 2010

everything can change

Tokamak 4 (1/5)
The Plasma code camp...
The starting line...
An Intel Compal JAX10 with Moblin
A Nokia N900 with Maemo5
Qt, KDE, Plasma, three developers and a designer
Alexis Menard — KDE Plasma for Mobile Phones 20/32

21. Introduction KDE Mobile Plasma Mobile
Tokamak 4 (2/5)
The Plasma code camp...
The state of art...
Maemo5 (and almost all others) : Multiple ’desktops’
that you can slide + a gridview to launch applications
Moblin : No real dedicated user interface
So pretty crowded but still the same approach more or less

Our ideas
Make the navigation more context aware : where i am,
what i am doing, who i am
You should be able to define activities : work, messaging,
social, games
A solution
The desktop should be based on activities
No big gridviews with all applications, just the relevant
ones
An activity switcher not on your way

How activities work?
Activities can contain widgets (related to the activity
itself)
If you want to do more with a given widget you can
switch to full view

Technical bits : Plasma core technologies
No it’s not mega bits...
Applets
have a built-in way to react on form factors they’re
running on
shares data using data-engines
can be shared on the network
are SVG themable
Containments
are containers for applets
can layout them if you want to
and they are applets!

32. Introduction KDE Mobile Plasma Mobile
Technical bits : Plasma Mobile
How it works...
QML is built in
Applets and Containments can be written in QML
Designers can provide QML for different devices
QML script engine : you can package/ship QML applets
on kde-apps.org

Disclaimer about the demo
Plasma-mobile is running fullscreen alongside with
hildon-desktop
Applets used here are not related to the activities, well
it’s a demo :D
LOTS of things are missing
