Do something when a particular tab is selected

[BigBen]

I have a tab widget, with 2 tabs. The second tab has a label. I want to display a movie in that label only when that tab is clicked and becomes active.

Is there something I can use to check if that tab is active or not?

In a slot connected to QTabWidget::currentChanged(), if the new current index is the one of interest then start playback. If it is not the index of interest then stop playback.
