      Then why not just show its content in a QLabel or a QTextEdit/QPlainTextEdit if you want to be able to modify it ?

            The function for send my keys is this:
            void enviarTecla(int tecla)
            {

            Display *display = XOpenDisplay(NULL);
            XKeyEvent event;
            
            switch (tecla)
            {
            case Qt::Key_Return:
                tecla = XK_Return ;
                break;
            case Qt::Key_Backspace:
                tecla = XK_BackSpace ;
                break;
            case Qt::Key_Escape:
                tecla = XK_Escape;
                break;
            case Qt::Key_Shift:
                tecla = XK_Shift_L ;
                break;
            case Qt::Key_CapsLock:
                tecla = XK_Caps_Lock;
                break;
            }
              int a;
              event.display = display;
              XGetInputFocus(display,&event.window,&a);
              event.root = 0;
              event.subwindow = None;
              event.time = CurrentTime;
              event.x = 1;
              event.y = 1;
              event.x_root = 1;
              event.y_root = 1;
              event.same_screen = TRUE;
            
              event.type = KeyPress;  //event.type = KeyRelease;
              event.keycode = XKeysymToKeycode (display,tecla);
              event.state = 0;
            
              XSendEvent(event.display, event.window, TRUE, KeyPressMask, (XEvent *)&event);
            
            
              event.display = display;
              XGetInputFocus(display,&event.window,&a);
              event.root = 0;
              event.subwindow = None;
              event.time = CurrentTime;
              event.x = 1;
              event.y = 1;
              event.x_root = 1;
              event.y_root = 1;
              event.same_screen = TRUE;
            
              event.type = KeyRelease;
              event.keycode = XKeysymToKeycode (display,tecla);
              event.state = 0;
            
              XSendEvent(event.display, event.window, TRUE, KeyReleaseMask, (XEvent *)&event);
              XCloseDisplay(display);

                               log.open(QFile::Append);
                               log.write("\n");//Jump the line in textfile
                               log.close();
                    
                            }
