Find file in folder recursive with Qt.

This function returns the absolute path of a file in a folder (or subfolder).
It searchs recursively in all subfolders until it finds the file or return an empty QString if the file is not found.

QString findFile( QString dir, QString fileName )

{

    QDir pathDir( dir );

    for( QFileInfo fileInfo : pathDir.entryInfoList() )

    {

        if( fileInfo.isFile() )

        {

            if( fileInfo.fileName() == fileName ) 

                return fileInfo.absoluteFilePath();

        }

        else if( !fileInfo.fileName().endsWith(".") )

        {

            QString found = findFile( fileInfo.absoluteFilePath(), fileName );

            if( !found.isEmpty() ) return found;

        }

    }

    return "";
