Tab changed event in customized tabbed view

With a customized tab view, I have several tabs in a layout.
(See Customized tabbed view
Within each tab, there are a group of views. I need to place some action code when the active tab is changed. Help to capture this tab changed event is appreciated.

You can look up the child widget using slicer.util.findChildren function and connect your callback function to the relevant signal.

Yes, the tab widget is found by this method. Thanks.
