Problems using SWT [message #97506] Wed, 13 July 2005 03:26 Go to next message

I've installed the versions of GEF and EMF that are attached to the
current VE build and they seem to be working correctly. My problem is
that whenever I try running one of the SWT smoke test samples, I get the
following stacktrace...

I've made sure to include the SWT library variable (even with JFace
support) on my build path. Not the jars, but the actual library. I am
using Java 1.5, but have set my compile settings to 1.4 for the project.

So I installed all the same plugins for the test pass on my thinkpad which
has JRE 1.5 installed, instead of my home Win2k SP4 machine running JDK
1.5. Everything now works without issue.

One thing I neglected to mention earlier, was that I could run the smoke
test shells as java beans just fine. The problem was that I couldn't look
at them in the VE.

On my win2k box I've also noticed the following trace, which I may have
missed the first time...

After talking with Gili it would seem this is due to alpha blending being
enabled. I'm going to pick up a newer build than the I20050708 and try
again.
