Can't get Finger Scrolling to work for Qt4.5.3 Applications

[ibrahim]

Greetings;

I've been trying to enable Finger scrolling feature on Some Qt4.5 
controls (scrollArea and ListView). I tried the solutions suggested in :
http://wiki.maemo.org/Qt/Finger_Scrolling  AND
 http://wiki.maemo.org/Qt4_Hildon#FREMANTLE_.28Qt_4.5.29 :
that is : setting the property "FingerScrollable" OR "FingerScrolling" 
to true for the entire application or per each control. But it just 
Doesn't Work!!
using the code provided in the post:

but it didn't compile on my scratchbox's ARMEL target either as it 
didn't recognize " QMaemo5KineticScroller"

I am using the default libqt4 installed with the n900 device (that is : 
when running the command dpkg -l libqt4* prints :

the same applies for the ScratchBox ARMEL target except the "libqt4-dev 
" package is installed.

What am i missing ???
thanx in advance,
