HP Motif/iX System Administrator's Supplement

Chapter 4  Using an HP Motif/iX Client 

This chapter describes the steps necessary to set up and use an X client
application on MPE/iX. The application will be executing on an HP 3000
host while its user interface will be displayed on an X display server,
such as an HP 9000 workstation or an HP 700/X monitor.

When a client application is invoked, it must be informed to which
display it should send its user interface.  This may be accomplished
through either of the following:

   *   an MPE/iX command interpreter (CI) variable

   *   the INFO parameter of MPE/iX's RUN command[REV BEG]

   *   the POSIX.2 shell environment variable

   *   a parameter to the application in the POSIX.2 shell
       environment[REV END]

Each of these methods is described below.

Note that applications that parse the command line directly instead of
using Xt should use the DISPLAY CI or shell environment variable to
specify a display screen.

The following picture illustrates the relationship between X clients
executing on an HP 3000 host and an HP 9000 host, and displaying their
output on the same X display.


          Figure 4-1.    

In this picture the X client application pizza is executing on the HP
3000 host and it is sending its output to the X display.  At the same
time, another X client is executing on the HP 9000 host and it is sending
its output to the same X display.  The X display screen shows the output
of an application that is processing on another host system in the
network.
