I understand that QT4.5.3 has partial support for hildon framework and QT4.6 will have the full support.
( source : http://qt4.garage.maemo.org/ )

Is this correct ?

I cant find any such info in the offial QT 4.5.3 documentation here ==> http://doc.trolltech.com/4.5/index.html

Im trying to figure out ways to create home screen and status menu widgets using QT.

for home screen widgets I came across a method by using ATOMs from X11 by which I could create a battery level widget(now in extras-devel) but Im sure QT would be having api's if its integrated with hildon , no ?
There is hardly any information at all about QT-hildon integration except what Ive stated above.

Can anybody with some more information about this integration help ?

is there anybody else who have been able to create QT widgets for desktop/status window ?

Thanks
