    Hello !
    first I'm new in c++ and i'm trying to make a Web Browser as a project for my exam
    i added an action add tab and it work but when i add a new tab it's not connected to the lineEdit so i cannot add a new link and the line Edit its connected only to the first tab the original one and this is how i add new tab
    @void MainWindow::on_actionAdd_tab_triggered( )
    {

    QWebView *webView = new QWebView();
        ui->tabWidget->addTab(webView, " NewPage " );
    

    ui->webView->load("http://"+ui->lineEdit->text());

    }

      Hi and welcome to devnet,

      Why does your UI have a webView, since you are adding them to the tabWidget ?

      What you can do for the line edit/ web view interaction is e.g. have a custom slot in MainWindow that will react on the line edit changes and call load on the current web view

      Hope it helps

        thank you for responding :)
        so the " tab calling action " have to be : @
        void MainWindow::on_actionAdd_tab_triggered( )
        {

        QWebView *webView = new QWebView();
            ui->tabWidget->addTab(webView, " NewPage " );
        

        }@

        and in the mainwindows i have to add

        @
        void MainWindow::on_Go_clicked()
        {
        ui->webView->load("http://"+ui->lineEdit->text()); //

        }
        void MainWindow::on_lineEdit_returnPressed()
        {
        on_Go_clicked(); // lineEdit react on go botton pressed
        }
        @

        so i think the problem is how to make UI interface with the current tab ?

          ui->webView just point to the web view you added in designer, not the one you just added. This one must be retrieved from your tab widget

              Not on your add tab method, in on_Go_clicked

              Have a look at QTabWidget's documentation to retrieve the current widget and qobject_cast to get the QWebView from that.

              Not everything you do includes using ui ;)
