C.10 Using DDD with LessTif
===========================

DDD includes a number of hacks that make DDD run with _LessTif,_ a free
M*tif library without loss of functionality.  Since a DDD binary may be
dynamically bound and used with either an OSF/Motif or LessTif library,
these _lesstif hacks_ can be enabled and disabled at run time.

   Whether the _lesstif hacks_ are included at run-time depends on the
setting of the `lessTifVersion' resource:

 -- Resource: lessTifVersion (class LessTifVersion)
     Indicates the LessTif version DDD is running against.  For LessTif
     version X.Y, the value is X multiplied by 1000 plus Y--for
     instance, the value `79' stands for LessTif 0.79 and the value
     `1005' stands for LessTif 1.5.

     If the value of this resource is less than 1000, indicating LessTif
     0.99 or earlier, DDD enables version-specific hacks to make DDD
     work around LessTif bugs and deficiencies.

     If DDD was compiled against LessTif, the default value is the
     value of the `LessTifVersion' macro in `<Xm/Xm.h>'.  If DDD was
     compiled against OSF/Motif, the default value is `1000', disabling
     all LessTif-specific hacks.

   To set the `lessTifVersion' resource at DDD invocation and to
specify the version number of the LessTif library, you can also use the
option `--lesstif-version' VERSION.

   The default value of the `lessTifVersion' resource is derived from
the LessTif library DDD was compiled against (or `1000' when compiled
against OSF/Motif).  Hence, you normally don't need to worry about the
value of this resource.  However, if you use a dynamically linked DDD
binary with a library other than the one DDD was compiled against, you
must specify the version number of the library using this resource.
(Unfortunately, DDD cannot detect this at run-time.)

   Here are a few scenarios to illustrate this scheme:
   * Your DDD binary was compiled against OSF/Motif, but you use a
     LessTif 0.88 dynamic library instead.  Invoke DDD with
     `--lesstif-version 88'.

   * Your DDD binary was compiled against LessTif, but you use a
     OSF/Motif dynamic library instead.    Invoke DDD with
     `--lesstif-version 1000'.

   * Your DDD binary was compiled against LessTif 0.85, and you have
     upgraded to LessTif 0.90.  Invoke DDD with `--lesstif-version 90'.

   To find out the LessTif or OSF/Motif version DDD was compiled
against, invoke DDD with the `--configuration' option.

   In the DDD source, LessTif-specific hacks are controlled by the
string `lesstif_version'.
