Detailed Description

FileReader is a helper class to read a file.

Reading a file can be done easily by using QFile and QTextStream, but adding some error checking introduces additionnal code every time. File reader does some checks for common cases and fills a error, avaibale in lastError().

Typical usage:

#include <Mdt/PlainText/FileReader.h>
#include <Mdt/ErrorDialog.h>
using Mdt::PlainText::FileReader;
using Mdt::ErrorDialog;
// In your function
FileReader reader;
QString filePath = "/some/path/to/file.txt";
if(!reader.readFile(filePath, "UTF-8",2*1024*1024)){
  ErrorDialog dialog(reader.lastError());
  dialog.exec();
  return;
}
