How to get mouse click event in GUI application regardless of widgets

[Seishin]

I'm working on adding a screensaver to my GUI application.
The issue is I want to get the general mouse click event and use it to update the timer of screensaver.
However right now when I click some push buttons or list items, only the clicked widget get the click event but outside container doesn't.
I wonder is there a way to get the general click event in the application instead of rewrite all the widgets to pass click event to their parents widgets?

Thanks in advance.

All UI events pass through the main application instance.
You can install an event filter on it to see them as they pass through.

See QObject::eventFilter().

Thanks. The eventFilter() works well for me. But the the thing annoying to me is I have to install the filter on each widget in my container. I wonder is there a more direct way to handle the "global click event" in application?

I already answered that, didn't I?
Maybe you only clicked the link instead of also reading the text of the previous comment?

I did read your comment but misunderstood to install the filter on children widgets, which is what I always did with event filter.
Now I installed the filter on qApp and it works like a charm.

Also I found a post with code explaination for who met the same issue.
