QScintillna (Want to check memory usage of lines in following Qt code in a profiler tool

[Qt Enthusiast]

void GQSciEdit::loadSourceFile(const QString& ofilename)

{
if (ofilename.isEmpty()) {
setText("<EMPTY FILE>");
filename = "";
return;
}

 if (ofilename.endsWith(".gpg") || ofilename.endsWith(".odb")) {
   setText("<ENCRYPTED FILE>");
   filename = "";
   return;
 }

 if (filename != ofilename) {
   QString msg = QString("Loaded file %1").arg(ofilename);
     if (FILE* fp = UFile::open(ofilename.toLatin1(), "r")) {
   QTextStream ts(fp, QIODevice::ReadOnly);
       setText(ts.readAll());
   setModified(FALSE);
   UFile::close(fp);
   d_filename = ofilename;
   emit fileNameChanged(ofilename);
      }
   }
}

I want to check memory usage of following line in above code setText(ts.readAll()); Can some one tell me the tool for it

Profilers are typically dependent on OS. You may have a look to gprof

On the other hand profilers eat a lot of CPU. Therefore do not try it on your large file. Probably it is much easier for you to measure time and required time with QElapsedTimer.
