QFile and FileRef for the same file

Question

I have a little problem with my Qt program.
There is a function which downloads a mp3 file (using QFile) and is called each time new datas are available to be written.
Once these datas have been written, I 'd like to construct a TagLib::FileRef variable, to read the bitrate of the file. The problem is this variable is always null, because the file is already opened.
How can I process, without having to close and re-open the file each time ?

Thanks

Answer 1

The data might not be written immediately by QFile to disk, so another file descriptor open on the same file wouldn't be able to read it.

Try to call QFile::flush() after each write.
