When I click on the minimize button of the application window, changeEvent is called. When I press ALT+TAB to bring the application window in front, the changeEvent is not called.

What event is called when I press ALT+TAB to get my application back into focus.

Is it focusInEvent ? I tried even this but there is another widget that gets the focus when the window is shown.

Can someone please help me with this?

Thanks a lot.
