This topic has been discussed a lot when I started the developpment of the now defunct DevQt. You should find the thread using the search function of QtCentre and typing something like "text editor with line numbers".

I myself have written such a widget for my IDE project (BTW version 0.4.2 of Edyuk is out. Get it on Sourceforge ! ;) ) and pasnox, author of Monkey Studio, aka Qt4DS, as also writen one. These sources being released under GPL you won't have any problem to adapt them to your needs.

The text folding is a little more complicated because it is a low-level interaction with the data of the document being displayed by your editor. Townk has made a little editor that allowed text folding but it was a little buggy with nested folding and I don't know if he progressed. For more information check out member list and try to contact him.
