The Shell Title

Presence

The shell title appears when
  • the object is top level, or
  • it is a popup whose `head attribute is 1 (the default);
its presence is not otherwise controllable.

Content

Its content is the value of `shelltitle if that attribute is non-empty.
Otherwise,
  • for the first top-level object shown or the object specified in s.WS, it is
    • 0_argv if _argv is not empty or else
    • the value of s.WSNAME, whose default is "A+";
    and
  • for all other objects, it is the name of the underlying variable.
Resetting the attribute to null causes the content to be selected as just described, but resetting it to the empty character vector is ignored.

The content can be all blank to give the appearance of no shell title.

The content must be a simple array.  If it is not a vector, its Ravel is displayed.  The content is not necessarily all shown, since the width of the shell title area is determined without reference to the shell title.

Font

The shell title font is controlled by the window manager; there is no A+ interface for it.

Color

The shell title color is controlled by the window manager; there is no A+ interface for it.
