@code{vertical-scroll-bars}.

@defun window-frame &optional window
This function returns the specified @var{window}'s frame---the frame
active. If @var{minibuffer} is neither @code{nil} nor @code{t}, the
minibuffer window is never included.
-Note that the window returned by @code{minibuffer-window} called with
-the argument @var{frame} is returned by @code{window-list} called with
-the same argument if and only if that window actually belongs to
-@var{frame}. If the minibuffer window is owned by another frame, it is
-not returned by this invocation.

The optional argument @var{window}, if non-@code{nil}, must be a live
window on the specified frame; then @var{window} will be the first
element in the returned list. If @var{window} is omitted or @code{nil},
