With a customized tab view, I have several tabs in a layout.  
(See [Customized tabbed view](https://discourse.slicer.org/t/customized-tabbed-view/24375)  
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.
