error " use of undeclared idetifier IO_ReadOnly ..."
-
Using this example I am obviously missing "OpenMode flags"
This resource does no help
https://www.digitalfanatics.org/projects/qt_tutorial/chapter08.html
defining the flags.Is this something QT specific ?
QStringList lines;
// QFile file;
QFile file( "file.txt" );
// OpenMode flags
// file.open()
if ( file.open( IO_ReadOnly ) ) {
QTextStream stream( &file );
QString line;
int i = 1;
while ( !stream.atEnd() ) {
line = stream.readLine(); // line of text excluding '\n'
printf( "%3d: %s\n", i++, line.latin1() );
lines += line;
}
file.close();

If you look at the foot of the example page you quote you will seeCopyright (c) 2002-2004 by Johan Thelin (e8johan -at- digitalfanatics.org).You must not use such an old example, it was written for Qt 3. Many things have changed since then. The newer constant for
IO_ReadOnlyisQIODevice::ReadOnly, which should make this compile, but I strongly suggest you simply ditch this example code as there may be other problems (e.g. I don't think yourline.latin1()will work) or deprecated code.
