Abstract

This article describes a method for reducing the number of windows used for a hypermedia application. The presence of hypermedia link markers in large numbers can significantly degrade system performance. The total number of windows used by the active applications directly affects the performance of a windowing environment. As applications add more windows, system performance (especially in the area of screen painting) degrades. Because hypermedia link markers are implemented as windows, they can exacerbate the too-many-windows problem.

Conservation of Windows in a Hypermedia Environment

       This article describes a method for reducing the number
of windows used for a hypermedia application.  The presence of
hypermedia link markers in large numbers can significantly degrade
system performance.  The total number of windows used by the active
applications directly affects the performance of a windowing
environment.  As applications add more windows, system performance
(especially in the area of screen painting) degrades.  Because
hypermedia link markers are implemented as windows, they can
exacerbate the too-many-windows problem.

      A method to reduce the number of windows used for a hypermedia
application is required.  Windows should only exist for link markers
that are visible or enabled.  Link markers should not have windows
created for them until they become enabled or visible.  When an
application (or user) disables a link marker, the hypermedia link
manager program should determine whether the link marker is visible.
If it is not visible after being disabled, then its underlying window
should be destroyed.  When an application (or user) makes a link
marker invisible, the hypermedia link manager program should check to
see if it is enabled.  If it is disabled after being made invisible,
then its underlying window should be destroyed.

      The hypermedia link manager program should use different
handles for the link markers and their underlying windows.  The
handle for the...
