      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.

                        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.
