QT: QFileInfo().exists() doesnt work

I have a network folder, mountet in /mnt/test. Now I would like to know, if the folder is available. I tried to check, if the folder 'tmp' exists.

This doesnt work for me. To check, if the folder is online, the function is called every 1-2 second.

if(QFileInfo(path + "tmp/").exists()) 
     test = dir.entryList();
else
     // device is not available

But every time, the programm tries to read the entryList().

Although there's nothing technically wrong with what you're doing, the method was never designed to be used in a polling scenario - QFileSystemWatcher is though.
