==Finger Scrolling== 

Kinetic scrolling is present by default in most scrolling widgets, eg. <code>QTextBrowser</code>, <code>QTableView</code>. If you want to tweak the kinetic scrolling parameters like inertia and acceleration then you can instaniate a <code>QAbstractKineticScroller</code> object like this: 

 QAbstractKineticScroller ks =  
   scrollArea->property("kineticScroller").value<QAbstractKineticScroller *>(); 

where scrollArea could be <code>QScrollArea</code> with some widgets added to it, or you could use implementations like <code>QTextBrowser</code>. 

You can tweak scrolling like this: 
 ks->setDragInertia( (double)value / 100.0) 
 ks->setMode(QAbstractKineticScroller::PushMode) 
 
etc., refer to the examples here for details: http://qt.gitorious.org/+qt-developers/qt/x11-maemo/blobs/4.6-fremantle/examples/maemo5/kineticscroller/main.cpp
