A dialog box is a variant of a pop-up menu---it looks a little
different, it always appears in the center of a frame, and it has just
! one level and one pane. The main use of dialog boxes is for asking
! questions that the user can answer with ``yes'', ``no'', and a few other
! alternatives. The functions @code{y-or-n-p} and @code{yes-or-no-p} use
! dialog boxes instead of the keyboard, when called from commands invoked
! by mouse clicks.
! @defun x-popup-dialog position contents
This function displays a pop-up dialog box and returns an indication of
what selection the user makes. The argument @var{contents} specifies

@code{x-popup-menu}, but the precise coordinates or the individual
window don't matter; only the frame matters.
+ If @var{header} is non-nil, the frame title for the box is
+ ``Information'', otherwise it is ``Question''. The former is used
+ for @code{message-box} (@pxref{The Echo Area}).

In some configurations, Emacs cannot display a real dialog box; so
instead it displays the same items in a pop-up menu in the center of the
frame.
