Abstract

An OS/2* "command-entry" Window allows a user to enter various commands and start programs as if working within an OS/2 full screen session. With new lines of information displayed in the OS/2 Window, previous lines of information scroll upward until no longer on the window. Much of the information scrolled off the window is no longer available and not retrievable by any current means. A method is required whereby the lost display information can be retrieved for further reference.

OS/2 Window Scroll Mode Option to Keep All/Extend Scrolled Information

      An OS/2* "command-entry" Window allows a user to enter various
commands and start programs as if working within an OS/2 full screen
session.  With new lines of information displayed in the OS/2 Window,
previous lines of information scroll upward until no longer on the
window.  Much of the information scrolled off the window is no longer
available and not retrievable by any current means.  A method is
required whereby the lost display information can be retrieved for
further reference.

      The OS/2 Presentation Manager* is a windowed environment.  Many
methods of displaying information in a windowed environment involve
the use of scroll bars in a window.  Some examples are Program Groups
(i.e. Main), File Manager and Printer Manager.  Scroll bars are
manipulated using the desktop pointer.  OS/2 Windows have scroll bars
and the vertical scroll bar is currently limited to a specific number
of lines.  OS/2 Windows lack extended scroll bar support causing
almost all of the information scrolled off the windowed area to no
longer be viewable.

      This invention describes vertical extended scroll bar support
for OS/2 Windows and methods for abling, disabling and working with
this support.  Vertical extended scroll bar support for OS/2 Windows
allows as much scrolled information to be retrieved by a user as is
desired.

      OS/2 Windows do not have extended scroll bar support currently
and with this invention the default is to not provide support upon
OS/2 Window invocation.  A user enables an OS/2 Window with extended
scroll bar support taking advantage of one of two available methods.

      The first method is to select "Extend..."  from the system menu
of the OS/2 Window.  This action displays the "Extended Scroll Bar"
dialog from which a user can specify the extra number of lines to
keep.  This specification is in addition to the normal number of
displayed and kept lines.  The OS/2 Window will immediately begin
keeping scrolled lines up to the specified number.  The number of
lines available for keeping is unlimite...
