Hi all. I have an import wizard that does some searching for a specific
file extension. I am trying to show a ProgressIndicator to the user to
indicate that the searching is taking place, as the search may take a
long time depending on the directory being searched. I found out the
hard way that if I call ProgressIndicator.beginAnimatedTask() and then
call my search, they both run in the UI thread and the ProgressIndicator
is not displayed. I am now trying to use a Job for my searching so that
I can display the ProgressIndicator to the user while the searching is
going on. The problem I'm having now, however, is that
ProgressIndicator.done() is being called before the search begins, and
the ProgressIndicator is not being displayed. The basic flow is as follows:
progressIndicator.beginAnimatedTask();
Job searchJob = new Job("Searching") {
@Override
protected IStatus run(IProgressMonitor monitor) {
searcher.search(directory);
}
}
searchJob.schedule();
progressIndicator.done();
I have read some articles about jobs and I have searched the e.platform,
e.rcp, and e.swt newsgroups for someone having a similar problem, but I
can't find anything that I have been able to apply to the situation that
I am in. Can anyone help?
Thanks in advance,
Brandon

Brandon,
I'm not sure whether it'll work in your case or not but you can try this
progressIndicator.beginAnimatedTask();
Job searchJob = new Job("Searching") {
@Override
protected IStatus run(IProgressMonitor monitor) {
searcher.search(directory);
return Status.OK_STATUS;
}
}
searchJob.addJobChangeListener(new JobChangeAdapter() {
@Override
public void done(IJobChangeEvent event) {
if (event.getResult().equals(Status.OK_STATUS)) {
progressIndicator.done();
}
}
};
searchJob.schedule();
All this does is that it ensures that progressIndicator.done() gets
called only when job is finished.
Hope that helps.
