As I explained in other posts, I'm trying to build an application that should be able to show a very long strings, just as shown at the image below.
I've already tried with some techniques in order to solve this problem: labels for any row, just writing in a scene as a graphicScene item / object, into a table, into a Simple text area...
But I get always the same low performance. Maybe I should I use openGL with an orthogonal projection (I just need 2D, it's just text) or something like that. There would be some trick to solve it, because I've seen some old applications that are able to load and show this kind of data, why not Qt?
Some help here?
