    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

                            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. ?

                                well It really depends what u want ?
                                Im not sure why you have
                                class plaint:public QPlainTextEdit
                                Instead of just using QPlainTextEdit directly ?

                                update:
                                i fixed the sample to do what u talked about first.
                                To change the tabtext for the tab.
