Hello!

I already know how to read a text from a .txt file using QFile, QTextStream and so forth, but I don't know how to open a .pdf file and read its content. I tried to do it in the same way recently, and what I got was:

So how do I open a .pdf file and read its content inside a Qt software?

Thanks!
