The client window is sitting on top of (is the child of) a window
owned by the window manager. The window manager's window is usually
larger than the client's window and the extra space around the client
window holds the window decorations (title bar, etc...). When you
click on the window frame you are clicking on the window manager's
window and the window manager gets the events and takes the appropriate
action. The client doesn't know anything about it and was not involved
in the process at all. The client doesn't own the decorations and
has nothing to do with them.
