[Qt-interest] QAbstractFileEngine problems

Apparently Yahoo's Webmail client is screwing up these days. Re-topic'ed.

Subject: Re: [Qt-interest] Qt Visual Studio Add-in for VS2010?

Thanks everyone! I got my stuff to work, only to find out that I can't use it. 
SQLite's BLOB handling is horrible. It has to load the entire thing into memory, 

which just won't work for me. (I also found that BLOBS cannot be incrementally 
appended to or read, which is an essential feature of write() an read()!)

So now I am have made a different AFE. But ran into a problem with my 
understanding.
Given that my serialized structure will be QMap archivemetadata, [(QString 
filename, QByteArray file), repeat as needed].
When I open the archive for writing, I need to write the archive metadata, but 
that depends on various settings.  How can I set these settings the first time 
it is opened, if some of the the settings come from various places?

// Copy a file into the archive. 
QFile in("1.jpg");
QFile out("wad:file.wad/1.jpg");
if (out.open(QIODevice::WriteOnly))
{
         // i need to write wad file metadata (QMap) here that is provided by a 
GUI. like 'sourceURL'
      // the metadata is on an archive basis and not an inner file basis. 
         //out.fileEngine()->setMetadata(map); // I want to do this

      while (!in.atEnd())
     {
          out.write(in.read(128*1024));
     }
}


What I want to do, is out.fileEngine()->setMetadata(map);

But unlike a QPainter, i don't have access to the engine? I figure this means I 
am doing something wrong. Any help?

Thanks!

That would be completely useless for you, since you can't link the VS 
integration libraries to LGPL software.

You know which company to complain to about that. :-/

PS: do you think you can configure your email client to properly quote emails?
