- "Motif" generally refers either to:
-
- 1) a window-system look and feel;
-
- 2) a particular toolkit (OSF's Motif widget set) and window
- manager (OSF's "mwm") implementing that look and feel.
-
- "Open Windows" refers collectively to a number of different window
- system components:
-
- 1) Sun's X11/NeWS server;
-
- 2) those X11 client-side (library, include file, application,
- etc. components of the core X11R4 distribution that Sun
- supplies in a particular OW release;
-
- 3) the additional toolkits (XView, OLIT, TNT) and window manager
- ("olwm") that Sun supplies;
-
- 4) additional X11 and NeWS clients that Sun supplies (although
- some are, I guess, considered part of the DeskSet).
-
- As far as I know, it is possible to run various distributions of the
- Motif widget set and window manager on top of Sun's X11/NeWS server and
- those components of the core X11R4 distribution that Sun supplies in a
- particular OW release.
-
- There may be bugs in the X11/NeWS server, and in the Sun versions of the
- client-side core distribution components, that may get in the way of
- Motif or prevent it from working (I think there are server bugs in some
- OW versions, for example), but there may also be patches for them.
-
- I don't know whether the Motif toolkit will work with the fairly-vanilla
- version of the Xt Intrinsics that come with Open Windows (OW 2.0 isn't
- up to the final X11R4 patch level; OW 3.0 allegedly is); you may have to
- put in an OSF version of the Xt Intrinsics for Motif's use.
-
- Later versions of Motif may require X11R5-vintage libraries, which
- current OW releases don't supply.
-
- I.e., installing X11Rx, and installing Motif, are two separate actions.
- You can install X11Rx on your Sun without installing Motif, and I think
- you can successfully use Motif on your Sun without installing X11Rx,
- although you may need to get patches from Sun for various parts of Open
- Windows.
-
- If you plan to install and use the MIT X11Rx server, you won't be able
- to use AnswerBook; it relies on the X11/NeWS server. There exist
- mechanisms to use the AnswerBook files with a PostScript previewer; they
- may be described in the FAQ.
-
- I suspect at least some of the other programs will work with the MIT
- X11Rx server (I suspect NeWSprint may even do so; it'd have to run its
- own private version of the X11/NeWS server to render the Postscript into
- dots on paper, but I think it can do so without conflicting with the MIT
- X11 server).
-
- However, some of those applications, while they may not require the NeWS
- and may work with the MIT server, may:
-
- 1) require the "olwm" window manager;
-
- 2) require some OPEN LOOK toolkit.
-
- If they require the "olwm" window manager, you won't be able to run
- "mwm" (I say "require" here; they may merely *prefer* the "olwm"
- manager, but be able to work with other window managers, perhaps by
- turning some configuration option on either for the application or the
- window manager in question - I think OPEN LOOK pushpins are one place
- where an OPEN LOOK window manager may be preferred by the application,
- but not necessarily required).
-
- If they just require some OPEN LOOK toolkit, installing Motif shouldn't
- be a problem - the Motif widget set is just another toolkit, and you can
- have plenty of toolkits installed on your machine, as long as you have
- enough disk space to store them and enough memory to keep them from
- constantly fighting for pages, and as long as they don't do Evil Things
- that cause one another problems (if they conform to the ICCCM, they're
- probably less likely to do so).
-
- (I assume here that you already have Open Windows, and thus already have
- the OPEN LOOK toolkits in question, which you could run on top of the
- MIT X11 server - assuming that they're X11 and not NeWS toolkits - and
- can probably run with the MIT X11 libraries.)
