QTabWidget::currentIndex() will return the index of the active tab.

should I use it exactly like or using the Tab object because I already tried it like objTab->(..) there no currenIndex method ?? – Engine Feb 27 '13 at 09:14
@Engine - no, this is the actual method, you will use that on your instance. If you have a Designer UI form you will need to do something like `ui->myTabWidget.currentIndex()` or without the `ui->` if you instantiate the user interface programmatically. – dtech Feb 27 '13 at 09:17

It's a method of QTabWidget, not of individual tabs. – Frank Osterfeld Feb 27 '13 at 09:54

I prefer ui->QTabWidget->currentWidget() == ui->Tab In case you rearrange your tabs and the index changes.
