HP Motif/iX Programmer's Supplement

What Is HP Motif/iX? 

HP Motif/iX is the product name for the components of both MIT's X Window
System and the Open Software Foundation OSF/Motif widget set that enable
an application using X Window System and OSF/Motif routines to execute on
a 900 Series HP 3000 computer system.

The X Window System (or simply X) provides an industry-standard
programmatic interface for implementing graphical user interfaces on
high-resolution bitmapped displays.  It allows for distributed
applications using a variety of display hardware that can be developed
without the need to address display hardware specifics.  This makes the
application more portable because it does not have to contain
machine-dependent display information.

While the X components of HP Motif/iX do not impose a particular
interface style, consistent behavior and appearance is possible by using
the OSF/Motif widget set.  HP Motif/iX offers the benefits of a standard
interface while providing great flexibility for application architecture,
display options, and interface style.

X employs client/server architecture, in which a software server process
managing a bitmapped display handles requests for specific services from
one or more client applications.  A client application using X is called
an X client.  A server process managing displays for use by X clients is
called an X display server.  This separation of client and server
functions allows display-specific processing to be confined to the X
display server software.

The client/server nature of X is particularly useful for an application
that executes on MPE/iX. By using HP Motif/iX, an X client executing on a
900 Series HP 3000 computer system can present a graphical user interface
on a bitmapped display attached to another machine that is managed by an
X display server.  There are several options for such display server
support, including Series 300/400 HP 9000 computer systems and the HP
700/X family of X terminals.


NOTE  900 Series HP 3000 computer systems do not support the execution of
      an X display server.
