    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.
