      hi
      u are using
      currentName=model->fileName(index);
      and I sort expect it to be
      currentName=model->fileName(mapped);
      if u still have sort on.
      //
      ui->tabWidget_2->setTabText(ui->tabWİdget_2->currentIndex(),ty+"*");//this not working

      ok. it looks strange. what are u trying to do ?

          ok
          and what part is not working?
          Is currentindex valid?

          int sel=ui->tabWİdget_2->currentIndex();
          qDebug () << "sel is:" << sel;
          ui->tabWidget_2->setTabText(sel,"test");

              Hi
              It should do the same in any slot or function.
              Are you sure its called
              and the index and text you use are valid?
              what did
              qDebug () << "sel is:" << sel;
              show you?

                  ok. ahh.
                  so index is not valid.
                  tabWİdget_2->currentIndex() is -1 which means there is no
                  current/active tab.
                  try clicking tab before testing the text changed or change to
                  the first one.

                  How many tabs did u add to it ?

                        sorry I am out of guesses.
                        if
                        ui->tabWidget_2->setTabText(0,"tabOne");
                        does not work, it have no idea then.

                        Did u place break point on it and made sure its called?
                        You are 100% sure you are adding tabs to ui->tabWidget_2 and not
                        ui->tabWidget_1 or something else ?

                            There is no reason that setTabText should not work.

                            please see this small sample that change tabtext when u write in edit

                                          hi
                                          you create a new version of main window here

                                          plaint::plaint(QWidget *parent):QPlainTextEdit(parent)
                                          {
                                            mw=new MainWindow();<<---------------- new main wind
                                            connect(this,SIGNAL(textChanged()),mw,SLOT(yildiz()));
                                          }
                                          

                                          mw is never shown and u never see u change the tabtext in this new version you create.

                                          in main.cpp, you already create a Mainwindow version so not sure why u create a new one. ?
