'setCurrentWidget' or 'setCurrentIndex' will do the job.

You can use either the pointer to the added widget or a numeric index.

See:

http://doc.qt.io/qt-5/qtabwidget.html#setCurrentWidget

http://doc.qt.io/qt-5/qtabwidget.html#currentIndex-prop

For example, if you have a tab widget with say 3 tabs, you can focus on the 2nd tab like this:

ui->tabWidget->setCurrentIndex(1);

If you just want to use the pointer to your widget (MyWidget of type QWidget) then here is another example:

MyWidget* pointerToMyWidgetInTab = new MyWidget();
ui->tabWidget->addTab(pointerToMyWidgetInTab,"Tab2")
ui->tabWidget->setCurrentWidget(pointerToMyWidgetInTab2);

Count the total number of tabs and set the last one:

ui->tabWidget->setCurrentIndex(ui->tabWidget->count()-1);

---

.h

private slots:
void setFocusAddedTab();
void on_addTabButton(); //Add Button

.cpp

void MainWindow::setFocusAddedTab() {
int x = ui->tabWidget->currentIndex()+1;
ui->tabWidget->setCurrentIndex(x)
   }

void MainWindow::on_addTabButton() {
ui->tabWidget->addTab(...,...);
setFocusAddedTab();
}
