Handbook
Windows
As evidenced in the last section, when
an
icon
is
opened, a
window
is
often displayed
on
the Desktop.
As
we
saw earlier, a
window can be used to view the contents
of
an
icon. Windows
can be moved
around
the Desktop, their contents
can
be edited
or
scrolled
through,
and
their size
can
be changed. We will
discuss these various operations using the window created by
opening the System Disk icon. This window
is
depicted in
figures
3.11
and
3.12.
EXAMINING
THE
WINDOW
Examine the illustration
of
a window in figure 3.12. The
bar
along
the
top
of
the window
is
known
as the title bar.
The
title
bar
includes
the
close
box,
the title
of
the icon which the
window
is
referencing,
and
an
optional
group
of
six parallel
horizontal lines.
We will refer
to
these as active window lines. They indi-
cate which window
is
active. The Mac allows more
than
one
window
to
be displayed
on
the
Desktop
at
the same time.
When more
than
one window is displayed, the
Mac
needs
to
know
which one the user
is
working with. This window
is
known as the active window. When
an
icon is opened, it
automatically becomes the active window. We will discuss the
procedure for changing a
window's status to active
later
in this
chapter.
The
bar
immediately below the title
bar
displays
informa-
tion pertaining
to
the icon. In the System Disk icon example,
we
see
that
two items
are
stored in the icon; these items occupy
235K
of
disk space;
and
164K
of
disk space
is
available.
The
main
portion
of
the window is used
to
display the
icons stored in the icon
that
is
open.
From
our
example,
we
can
see
that
the System Folder, Empty Folder,
and
Font
Mover
icons are stored in the System Disk icon.
