Qtabwidget addtab duplicates tab on second click

Ucn_

Hello
I have two buttons with two slots, on click I add a new tab to my qtabwidget, this works. However, It only works the way I want if I have one button, I can click multiple times it won't duplicate the tab, but If I click the second button which creates a second tab, then click the first button it duplicates the tab. If I come back to second it duplicates too. And it keeps duplicating. I would like to know how I can prevent from duplicating on second click. Thanks
my code:

bool MainWindow::control_tab(QString addst){

    bool kontrol = false;

    for(int i=0; i < ui->open_tools_tab->count(); i++)
    {
        if(addst == ui->open_tools_tab->tabText(i))
        {

            kontrol = true;
        }

        else if (addst != ui->open_tools_tab->tabText(i))

        {

            kontrol = false;

        }

    }
    return kontrol;
}

void MainWindow::on_tB_add_students_clicked()
{
    addst = "Add student";

    if (control_tab(addst) == true)
        {
             for(int i=0; i < ui->open_tools_tab->count(); i++)
             {
                 if(addst == ui->open_tools_tab->tabText(i))
                 {

                    ui->open_tools_tab->setCurrentIndex(i);

                 }}
             ui->tab_menu->setCurrentIndex(1);

    }

        else
                 {

                    ui->open_tools_tab->addTab(new QWidget(), icon, addst);

                }
}


void MainWindow::on_tB_add_teachers_clicked()
{
    addst = "Add teacher";

    if (control_tab(addst) == true)
        {
             for(int i=0; i < ui->open_tools_tab->count(); i++)
             {
                 if(addst == ui->open_tools_tab->tabText(i))
                 {

                    ui->open_tools_tab->setCurrentIndex(i);

                 }}
             ui->tab_menu->setCurrentIndex(1);

    }

        else
                 {

                    ui->open_tools_tab->addTab(new QWidget(), icon, addst);

                }
}

What are you trying to achieve? Only adding the tab once? Then you should fix your control_tab() function to return true once the tab with the given name is found.

Christian Ehrlicher, Thanks. Removing the "else if" and returning "true" in the control_tab() fixed.
