TableTree [message #459613]

I am trying to work with the TableTree control. There is the viewer
abstraction that provides content and label support for Tables and Trees,
but I cannot find anything that provides the same level of abstraction for
the TableTree control. I have tried to apply the TableViewer to the
TableTree's table control -> new TableViewer(tableTree.getTable()), but it
doesn't work. Is there such an abstraction, or do I need to create my own
(or interface directly to the TableTree control)?

TableTree has been deprecated in 3.1- you can use Tree directly.
But if you insist, you can use org.eclipse.jface.viewers.TableTreeViewer.

Okay. does this mean that the tree can support the tree and table functions
now? Can I then use the TreeViewer too? What version of SWT/JFace did the
table functions get incorporated into the Tree, or am I missing something?

Sunil is right. TableTree should not be used any longer.

Below is the code for using a regular tree with columns:

Thank you for your input. I downloaded Eclipse 3.1. Installed it. Created
a project to test this. Added the necessary required libraries, but I
cannot run it due to the UnsatisfiedLinkError: no swt-win32-3138 in
java.library.path error:

I tried to:
1) add the -Djava.library.path= statement in the runtime VM arguments
2) changed my system path to point to the directory with the DLL
3) copied the DLL into my system and system32 folders, but nothing works

Did something else change in the new version of eclispe that prevents me
from setting this variable?

Try "Run As > SWT Application". This will always work.

If I had to guess, I bet you're point at the wrong DLLs. Did you
just add the SWT .jar file as a library dependency in your project? In
Eclipse 3.1, the SWT plug-in does some special Eclipse stuff, and so the
DLLs are extracted from the .jar file at runtime by the Eclipse plug-in
infrastructure.

The recommended way to use SWT in your app is to download the
standalone SWT .zip file and import it using the "External Plug-ins"
import wizard. This will put all the DLLs in a project in your
workspace in a sane way, and you can use "Run As > Java Application" and
it will "just work" without you having to add anything to your library path.
