I want to know what is optimal size of bufferSize in following code
class myView : public QScintilla {
void myView::readFile(QString ofilename) {
if (FILE* fp = fopen(ofilename.toLatin1().constData() "r")) {
QTextStream ts(fp, QIODevice::ReadOnly);
int bufferSize = 8192;
do {
QString s = ts.read(bufferSize);
append(s);
} while(!ts.atEnd());
setModified(FALSE);
UFile::close(fp);
d_filename = ofilename;
emit fileNameChanged(ofilename);
}
}
}
so that we do not see any run time issues
