Integration of SI/ComboBox and SI/NumericText
	    ----------------------------------------------

This directory contains the files required to integrate the SI
public domain ComboBox 1.31a of 20/3/1995, and NumericText 1.31a of
20/3/1995 widgets into WorkShop Visual (version 6.0).

Files contained in this directory are as follows:

	README          - These notes.

	Makefile        - creates an visu binary with the
			  chosen SI widgets integrated.

	SI.xdc          - visu_config configuration file for SI widgets.

	SI_stubs.c      - additional code for the SI/table integration.

	app-defaults/   - Resources for widgets in WorkShop Visual integration.

	bitmaps/*.bm    - bitmap files to represent SI/ComboBox and 
			  SI/NumericText widgets on WorkShop Visual
			  widget palette.


Acquiring the SI Widget Set
---------------------------

The following contact should work:

	Institut fuer Geometrie und Praktische Mathematik
	RWTH Aachen, Germany

Integrating SI/ComboBox, SI/NumericText with WorkShop Visual
----------------------------------------------------------

1.  Start visu_config and use the File/Open menu option to load the
SI.xdc file.  Three families will be listed:

	SI/family   - contains SI/ComboBox, SI/NumericText widget
		      classes.

	ComboBox    - contains SI/ComboBox widget class only.

	NumericText - contains SI/NuemricText widget class only.


2. Select the 'Config file' option from the Generate menu. 

	The Generate dialog contains a toggle button for each
	family.

	Select one or more of these families depending on the
	combination of widgets that are to be integrated into
	WorkShop Visual.

	Simplest is just to select "SI"

	Click on OK to generate the config.c file. 

	Repeat this procedure for the 'Code file' menu option to
	generate code.c.

3. Check that the Makefile is configured for your system and that
pathnames are correct.

	Simply type "make".

	After the build has successfully completed a
	'visu.bin' executable incorporating the required SI
	widgets will have been created in the local directory.

4. This binary may be invoked by setting the environment variable
USER_WIDGETS to the name of this directory (i.e. USER_WIDGETS=SI)
and invoking WorkShop Visual as normal. 

	For this to work, you should install this directory as SI
	into the user_widgets sub-directory of your WorkShop Visual
	distribution.

5. This widget integration can be made the default for your site by
moving or copying this directory to 'local' (including any bitmap
and app-defaults sub-directories) within the WorkShop Visual
distribution.
