It did.  No problems so far.

This does not work.  If I highlight Display, I get:

The source attachment does not contain the source for the file
Display.class.  You can change the source attachment by clicking Change
Attached Source below.

Project->Properties-> Java Build Path

SWT is there and under it is org.eclipse.swt.gtk.linux.x86.  And under
Native library location it has.../workspace/org.eclipse.swt.gtk.linux.x86/
- non modifiable.

"Build path contains duplicate entry: 'org.eclipse.swt.gtk.linux.x86' for
project test"  So I removed it here.

It works now.

FWIW, I have never had to manually add anything to do with SWT to my
projects before. 

Thanks for your help.
