I'm guessing that the widgets might move to something more like java.
It's great that the JVM is now shipped with the IDE, I've had
difficulties initialising the java bridge prior to this release.
All I have to do is
setenv IDLJAVAB_LIB_LOCATION /usr/local/itt/idl70/idlde/bin.linux.x86/
jre/lib/i386/client
/usr/local/itt/idl70/bin/idl -32
and my IDL-java bridge is ready.

Personal communication at a public meeting. The plan,
as I understand it, is not for them to be either
removed or significantly changed. The plan is for
them to be abandoned for something "WAY BETTER".
(If you have heard this story before, I apologize.)
The idea would be to have...I'm not sure what to call
them...GUI Units, I guess... that work identically on
all platforms and require a single code base to maintain.
This is unlike the current widget infrastructure, which
requires a great deal of effort, especially for Motif,
and over the years has evolved functionality that is different
on different platforms.
At the same time as these new "whatchies" are being
developed, a GUI Builder will be created that can
create GUI programs that do not involve jumping through
a lot of hoops to pass data around, etc.
All of this is a "long-term" goal, which in the context of
the meeting, meant sometime in the next 5 years or so.
I think you can rest assured that your widget programs
will still run far into the future. However, I think you
can abandon hope that you will ever have a TABLE_WIDGET
that works well.
Cheers,
David

Can you please expand on this and/or supply a reference? Is support for
widgets being removed or significantly changed?
Thanks,

Great tips! Works great. And it seems to integrate with my SVN
repository, too.

Hi Mark,
I think that what you describe is pretty typical for most users, so
don't despair. The problem with the old DE was that its projects
didn't necessarily have anything to do with the files as they existed
out on disk. You could have a project with files, each of which came
from a different location on your hard drive. The old projects were
really only useful for creating save files, not for maintaining
organization.
With the new IDL Workbench, there is a single Workspace, as you
describe. (You can have more than one Workspace, but let's ignore that
for now.) The Workspace contains multiple projects. A project is
simply a collection of files and folders, that is laid out *exactly*
as they exist on your drive. These files and folders have to *all*
reside within a Project folder, which can be located either within
your Workspace or in a separate location.
Here is what I would recommend:
1. See if you can organize your 203 directories into a few logical
high-level directories. It sounds like you might already have it
organized this way.
2. Use the "New IDL Project" wizard to import these high-level
directories into your Workspace, with one project per directory.
* Fire up the "New IDL Project" wizard (via the File->New->IDL
Project or from the Toolbar button)
* Give your project a name, e.g. "Work Project 1", "Utilities",
etc.
* For Location, choose "Create the new project from an existing
directory", and choose your desired directory to import.
* Since you are managing the path yourself, be sure to deselect the
"Update IDL path preference" toggle.
Once you hit Finish, your new Project will get created. Note that the
files are still in their original locations - they are not copied. But
now the Workspace contains a new Project that contains a reference to
all of the files and folders within that subdirectory.
Now... try something cool like Search (Ctrl+H) across multiple files.
Or try Ctrl+Shift+R, to bring up the Open Resource dialog. Then start
typing the name of one of your files, to quickly locate it. Or you can
do things like use "; TODO" markers in your IDL comments.
Let me know if you have more questions.

It is SO nice to know I'm not alone in the world.

You can imagine how vindicated all those people who
never used widgets will feel in the next release!
(Or is it the release after that? My head is starting
to hurt with all this new stuff. Where is the plug,
by the way, for that Subversion stuff? I'm all for subversion.)
Cheers,
David
