Thanks for Reply.

Ok, I will try your code but want to ask one thing where u pass the file Bytes into the text edit.

Can this function is enough to do the job or I have to implement some other feature also of text edit.

Also I want to know whether function like
getAddressFromPosition
is inbuild function or they are defined by you.

m_pProgamWindow->setText(text); //where text is QString and m_pProgamWindow is object of text editor

Hey Rajesh is Text edit sufficient to handle the large amount of data ?
I mean if the data is of 20 Gb of a single file?

Almost certainly not if you are intending to load the entire file into RAM. You'll need a 64-bit environment, probably 64GB+ of RAM, and lots of coffee for waiting time to even have a chance.

Loading a small working section, ie.e page at a time, of a file is trivial enough using seek() and read(). Alternatively you can use QFile::map() to make part of a huge file appear in-memory.
