Report in PDF format, I wanted something to customize the process to generate the report, because I was told that there tools that will help this part.
Hmmm... PDF format.... in Java I only know iText. In C++ I don't think there is any Open Source effort with API for us to read/write PDF format I think.
I'm sorry for not being specified. I have done a c + + application using the Qt Creator, and I want to create a report with data from a database (mysql) and show the user in PDF format.
I do not know any way to generate reports automatically, wanted an indication of a tool or library for generating reports in C + +. And I wanted a tool that is totally free, like LGPL.
I guess I was specific.
You still haven't explained what a "report" is supposed to be.
If you want to create a PDF document, you should just say so.
There are libraries that allow you to create PDF documents such as libharu (C) and libpodofo (C++).
