[Qt-interest] how to support pinch/unpinch

[_h_]

Hi Denis Dzyubenko,

Thank you for more information.
As there are various brand of laptops available in market with
touchpad support, so Qt-4.6 would be supporting all these hardware OR
only subset of them ?

I am more curious to know, how Qt will be getting touch events from
platforms that just have multitouch hardware, can you please share
some knowledge.

Thank you.
