Detecting the last empty line in a file

[Ti_Thom]

Hi,
i am writing a piece of code where i modify a file (add and remove entire lines).
The problem is that i am unable to grab the last empty line. The current code is :

QStringList file_text;
while (!in.atEnd()) {
  QString line = in.readLine();
  file_text.push_back(line);
}
file.close();
//processing the lines and then save

QStringList file_text;
while (!in.atEnd()) {
  QString line = in.readLine();
  file_text.push_back(line);
}
file.close();
//processing the lines and then save

To copy to clipboard, switch view to plain text mode 

is there any way to get the last empty line ? (or at least to detect if there is one)

Well,

if (line.size() != 0) {
    // do something
}

if (line.size() != 0) {
    // do something
}

To copy to clipboard, switch view to plain text mode 

should do the job, I guess.

May be something like this:

QStringList file_text;
do {
  QString line = in.readLine();
  file_text.push_back(line);
} while (!in.atEnd());
file.close();
//processing the lines and then save

QStringList file_text;
do {
  QString line = in.readLine();
  file_text.push_back(line);
} while (!in.atEnd());
file.close();
//processing the lines and then save

To copy to clipboard, switch view to plain text mode
