If you've reached the end of the file, atEnd() returns TRUE. The file handle is returned by handle(). Here is a code fragment that uses QTextStream to read a text file line by line. It prints each line with a line number. \code QStringList lines; QFile file( "file.txt" ); if ( file.open( IO_ReadOnly ) ) { QTextStream stream( &file ); QString line; int i = 1; - while ( !stream.eof() ) { + while ( !stream.atEnd() ) { line = stream.readLine(); // line of text excluding '\n' printf( "%3d: %s\n", i++, line.latin1() ); lines += line; } file.close(); } \endcode Writing text is just as easy.
