Thanks, that helped. Even QDeclarativeGeoMap does not receive any
mouseEvents in touch screen device I still need to grab also mouse events.

Now I have made fixed version of QDeclarativeGeoMap that works with
flickable. It just requires implementing preventStealing functiuonality. I
also noticed that it would be usefull to prevent some marigin on edges
where it does not grab events so that i could flick flickable from swiping
from egges.
