Hi, I'm trying to create a signal, but I can't see the code. I'm trying to prevent reading and writing to a file at the same time with QSetting. Is there perhaps another way? Thanks.

mainwindow.h

Qt Code: 
  1. #ifndef MAINWINDOW_H
  2. #define MAINWINDOW_H
  3.  
  4. #include <QtWidgets>
  5.  
  6. #include "parametres.h"
  7. #include "threadsondes.h"
  8. #include "gainable.h"
  9. #include "affichecons.h"
  10.  
  11. class MainWindow: public QWidget
  12. {
  13.     Q_OBJECT
  14.  
  15. public:
  16.     MainWindow(QWidget *parent = nullptr);
  17.  
  18. signals:
  19.     void lectureEnCours(bool m_lecture);
