Not Evaluated If you try to append some text in an existing file it does not append rather it over writes it in the begining of the file, attached example shows this behavior
#include <QFile> #include <QDebug> int main(int argc, char *argv[]) { QFile file("myNewTestfile.txt"); bool ret = file.open(QIODevice::WriteOnly); Q_ASSERT(ret); file.write("Testing First line\nTesting other line"); ret = file.flush(); Q_ASSERT(ret); file.close(); Q_ASSERT(!file.isOpen()); ret = file.open(QIODevice::WriteOnly | QIODevice::Append); Q_ASSERT(ret); file.write("APPEND new Line"); ret = file.flush(); Q_ASSERT(ret); file.close(); }
It is reported that it is limited to Windows only it works good on Linux
