        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 ?

                              Well i'm out of guesses. sorry.
                              There is no reason that setTabText should not work.

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