        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();
                      
                              }
