[Qt-interest] How to copy an embedded resource file to the file system?

[Marcelo Magno T. Sales]

Hello,

I would like to copy a file which is embedded in the executable (as a qt 
resource) to the file system. How to achieve that?
QFile::copy() fails with error 14 (copy error).

I've tried something like:
QFile(":/path/file").copy("/path/in/filesystem/file");

or

QFile file(":/path/file");
file.copy("/path/in/filesystem/file");

But it fails with the above mentioned error (checked with 
QFile::error())

Thanks,

Marcelo
