Abstract

Multi-Media support requires the ability to link different objects on the display screen for consequential update of information. By simply updating a spreadsheet, which may be linked to a graph, the graph will be updated. Current solutions require the linking of a library for an API to perform a linking interface. This requires a distribution and support for vendors' applications to implement Multi-Media linking. In addition, when designing this API, all aspects of the definition of linking must be thought through; this could never be a complete solution since unknown new ideas will occur.

Multi-media Update Linking

       Multi-Media support requires the ability to link
different objects on the display screen for consequential update of
information.  By simply updating a spreadsheet, which may be linked
to a graph, the graph will be updated.  Current solutions require the
linking of a library for an API to perform a linking interface.  This
requires a distribution and support for vendors' applications to
implement Multi-Media linking.  In addition, when designing this API,
all aspects of the definition of linking must be thought through;
this could never be a complete solution since unknown new ideas will
occur.

      The Presentation Manager* (PM) product uses a message passing
system for updating the presentation of information on the screen.
This is called painting and the message is WM_PAINT.  For a solution
which does not require a library for an API, a new message called the
WM_LPAINT  message is to be defined which encapsulates the ability to
perform the link process and link updating.  The inherit
characteristic of a message provides the ability for communication
between unknown applications.  By simply knowing the protocol for the
message, one can link applications.

      The physical connecting of applications is performed by the
user through the mouse interface.  The user can simply "click on" one
application window and drag a rubberbanding link to another
application.  It is possible under the PM system to provide this
interface.  The underlying management of information needs to be
defined to enable this link interaction.

      The WM_LPAINT provides a solution which requires very little
overhead, and allows for future modification for unknown new ideas to
be included.  If an application wishes to support Multi-Media, it
must support the WM_LPAINT mes...
