You need to understand how focus in X works first.

You set the focus, or the apps set the focus when you send a TAKE_FOCUS
protocol message, then the focus may actually change and Openbox will
receive all sorts of FocusIn and FocusOut events which it filters and/or
uses.

The focus_client is the client currently focused, which is tracked from the
FocusIn/Out events.

X Focus is the most evil thing in the world.
