Problem with QScrollview and QPainter

[Sarma]

That would be better. Iam sending you again two files and the complete code. These are the files that iam sending:

small.txt (that contains the small file for which small.gif is sent).
large.txt ( that contains the large file for which large.gif is sent) and
source.cpp ( where the code has been written).

Note: The "/tmp/parsetext.txt " in the code at any time contains the file for which graph has to be generated. And sir, I have not changed the code as you said previously (reading the file in another method). I have tried that but I faced the same problem of over-writing for large files. Kindly take time to see this and help me in what ever way possible.

Thanks alot for your co-operation.
with regards,
sarma.
