Hi,
	I have been using Unidraw for some of my applications. Now a 
	stage has come when I need to use the Connector Class inside 
my application. 
	I would really appreciate if someone could point me to some sample 
	code using the connector class.  A small sample code would be great.
	Thanks for your valuable time.

I've just started to use the doc document editor and have the 
problem that it produces postscript with font file names like:


18 /-adobe-times-medium-r-normal--18-180-75-75-p-94-iso8859-1 sf
18 /-adobe-times-bold-r-normal--18-180-75-75-p-99-iso8859-1 sf

which of course the posctscript printer doesn't understand, how
do I get it to produce normal font names ie

18 /Times-Roman sf
18 /Times-Bold sf

I have a very similar problem in a Unidraw program (IV 3.1beta, Sun OS 4.1.1,   sun C++ 2.1). 

We have a graphic editor which creates Nodes (derived from GraphicComps) and
deletes them later in the program. The program crashes after running for some
time and usually the error is not repeatable (doesn't crash at the same point always).

The program crashes in line browser(class Editor)->Update(); dbx shows that it is crashing in function ivUHashElem(.. ) which is accessing some Hash tables.

Following the pointers indicated that browser->Update() was trying to dereference pointers to Nodes which were earlier "Removed" and the memory explicitly deleted.

I am not able to create the exact error message now as I temporarily do not have the data of my program.

Hope this is a real bug and it get's fixed

Is there a way to insert an interactor into an open window (within an
inclosing interactor) without redrawing the entire window.  We now we
can do this if we call resize on the enclosing interactor, but that
causes the entire interactor (window) to be redrawn.  We are using an
in-house modified Unidraw with IV3.0, so switching to glyphs and using
patch is not on option.

I would like to develop something very similar to schem with
Interviews 3.1 in order to work on electrical network analysis.

I am trying to compile schem with Interviews 3.1 and I am running into
some undefined variables... I think I am doing everything right by
using -Div2_6_compatible, -I../../../.././src/include/IV-2_6 for my
compiler, etc.

For instance, one of those error is :

/depot/lang/bin/CC -I/usr/local/X11R5/include     -Dcplusplus_2_1
-Div2_6_compat
ible   -I../../../.././src/include/IV-2_6 -I../../../.././src/include
-I/usr/loc
al/X11R5/include  -pipe -c ../scmcmds.c
"../scmcmds.c", line 356: error:  member Parent undefined

Has anyone developped something similar for Interviews 3.1 or did
anyone ported schem to 3.1??

Any help would be much appreciated!

Schem is a simple schematic capture system that demonstrates how one
can use connectors (pins) in a Unidraw application.  It would help to
have a copy of my thesis to understand how.  You can order a copy for
a nominal charge from Naomi Schulman <schulman@shasta.stanford.edu>.
Ask for tech report CSL-TR-90-427 titled "Generalized Graphical Object
Editing."  You can ftp schem itself from interviews.stanford.edu in
pub/contrib/schem.tar.Z (InterViews 3.0.1-compatible) or
pub/contrib/schem-3.1b.tar.Z (3.1 compatible).

Even converting a postscript-file to a bitmap is not easy. For that
you need a Postscript interpreter. This is exactly what Ghostscript
is, and does. So, using ghostscript you could convert an arbitrary
postscript file to a bitmap (which you theoretically could import into
idraw). It probably doesn't do much good though, since all the objects
are lost (or "flattened").

HI

I am new to IV & need a bit of help...
Here is the problem.

It is a Unix based project with mutilpe process. All of these process 
communicate via sockets. There is one process which is an IV application.
The intention is that the IV process does its thing as well as 'listen' to
a number of sockets for data.

What has been tried upto now is the Dispatcher class. We had a couple of
problems and did not suit our needs very well. The idea of creating a child
process and assignning it the task of converting socket data to RPC data was
also considered.

Any comments or solutions would be greatly appreciated.

Thanks in advance.

This is not a problem with interviews, it is a problem with your
make command, which is looking for implicit rules.

From SunOS 4.1.1 man page for make:

     make reads in the standard set of implicit  rules  from  the
     file  <make/default.mk>, unless -r is in effect, or there is
     a default.mk file in  the  local  directory  that  does  not
     include that file.

Check /usr/include/make to see if default.mk exists.  It is part
of the standard SunOS4.1.1 distribution.

I don't believe Gnu make uses such a file, so probably someone
blew away that directory.  Ask your system administrator.

I'm more or less sure that i'm missing something obvious here, but i can't
for the life of me work out how to position a pushbutton at an arbitrary

I'm trying to create a canvas, on which there are both buttons & simple
graphics, and consequently i need a way to position the buttons in amongst
the graphics.

I can sort of see how i might get the same effect by creating a class with
my own redraw etc functions, but it seems a very elaborate way of getting a
simple effect.

thanks in advance

Corel Draw can import PostScript too  (it works the same way:
you have to ungroup if you want to make changes other than
resize/rotate/etc)

I thought the same thing until I saw Island Draw 3.0.  It
has an option to import Postscript, and it seems to accept
arbitrary Postscript.  I have fed it single page Postcript
files from Illustrator, Corel, Ventura, Designer, Eroff,
and hand-coded files, and it made Island Draw objects out
of them.  The file initially opens as one grouped object,
but if you ungroup, you get editible objects.  I was quite
impressed.  I don't doubt there are ways to fool the
interpreter, but it works for output from drawing and
publishing packages, which is what I need it for.

Using -monochrome or *gui: monochrome in Xdefaults doesn't do anything because
the monochrome kits aren't implemented (at least not in 3.1-beta on a Sparc
with cfront).  Have the mono kits been implemented in 3.1-beta3?
