Later I want to display the same File whenever user want to read it.

There is no Qt functionality to display a PDF file. You need Poppler or some other third party library/application to do that.

You have a general answer to general question. We do not know what your code is doing that makes TXT files work and not PDF... you don't show us anything that would let us diagnose the problem.
