[Qt-interest] QPlainTextEdit and files larger than 1G

[anders.bakken at nokia.com]

I have a little Qt-based LGPL project that does this kind of thing (with limited formatting as well).

Feel free to check it out here:

It's functional and I don't know about a whole lot of bugs.

Kate has its own paging code. It reads chunks of the file and may save the
processed data to disk. It doesn't try to keep the entire Unicode decoding of
the file in memory, much less the entire rendered data.

That's the kind of stuff that QPlainTextEdit does not have. It was never meant
to be used with huge files.
