Hi,

I added a popupmenu and it will only pop out on a project. I added
IProject objectclass.

I wanted also that the popupmenu will only show if my.xml is on that
project.

How will I do that? Is there any existing property tester in eclipse like
jdt.launching.hasNature?

I think the last time through this the most effective way to do this was
to set a persistent property on the project if the file exists. That
way you can easily test the property (assuming core expressions) using
existing org.eclipse.core.resources property tester.

The other alternative is to write your own property tester and when the
project is selected, go looking for your file.

Later,
