Hi,

I am new to ResourceChangeListeners and I was wondering how I can get
notified of a projects deletion or add. Is there any sample code?

I tried with if(event.getKind()==IResourceDelta.REMOVED) but that didnt
work for me.

So I am a bit stucked.

You add a resource change listener with the pre_close and pre_delete mask.

Here is a simple one that I use:

project.getWorkspace().addResourceChangeListener(resourceTra cker,
IResourceChangeEvent.PRE_CLOSE | IResourceChangeEvent.PRE_DELETE);

private class ResourceTracker implements IResourceChangeListener{
public void resourceChanged(IResourceChangeEvent e) {
// About to close or delete the project and it is ours, so we need to
cleanup.
// Performance: It has been noted that dres.equals(...) can be slow
with the number
// of visits done. Checking just the last segment (getName()) first
before checking
// the entire resource provides faster testing. If the last segment is
not equal,
// then the entire resource could not be equal.
IResource eventResource = e.getResource();
if (eventResource.getName().equals(getProject().getName()) &&
eventResource.equals(getProject())) {
cleanup(false);
return;
}
// Note: the BeaninfoModelSynchronizer takes care of both .classpath
and .beaninfoconfig changes
// in this project and any required projects.
}
