hi friends,
i am having a stacked widget having six pages, each page having an identical frame
i added a new page to my stacked widget and a new frame .. when i added this one and start make and run ..
in my console its printing
" prev value: in = 0xff
post value: in = 0xd0"

i dont know where it is printing .. can any body solve this one before ...?
please help ...!

why are you concerned about that value..isnt your application working fine?

yes its working fine ... i thought it was some warnings ... !

so, have you grep'd for "prev value" in your sources?

yes i greped the value
grep -ri "post value" * and find it..
