I start Job.shedule(); and before end of run method
I try open same Dialog. How do I get shell from RCP ?

PlatformUI.getWorkbench().getDisplay() don't work,
because it is not UI thread.

I haven't tried it in this context, but Display.getCurrent() or
getDefault() might work.

Hi Janko,

You might try something like the following:

In your Action (or other code that is on a UI thread, pass the Display
as a parameter to your Job (for example, in its constructor).

Then open your dialog within the run() method of display.asyncExec

class RequestMailDownloadServiceJobChangeAdapter extends JobChangeAdapter
{
Display display;
public RequestMailDownloadServiceJobChangeAdapter (Display display)
{
this.display = display;
}// public RequestCertificateJobChangeAdapter (Composite parent)
//////////////////////////////////////////////////////////// ////////////////
public void done (final IJobChangeEvent iJobChangeEvent)
{

display.asyncExec
(
new Runnable ()
{
public void run ()
{
Shell shell = display.getActiveShell();
Job job = iJobChangeEvent.getJob();
RequestMailDownloadServiceJob requestMailDownloadServiceJob =
(RequestMailDownloadServiceJob) job;
int encryptedObjectCount =
requestMailDownloadServiceJob.getEncryptedObjectCount();
String message = "";
if (0 == encryptedObjectCount)
message = "No Messages available for download";
else
message = "Sucessfully downloaded " + encryptedObjectCount + "
messages";
;
MessageDialog.openInformation(shell, "Message Download Request",
message);
}// public void run ()
}// new Runnable ()
); // display.asyncExec

}// public void done (IJobChangeEvent iJobChangeEvent)
}// class RequestMailDownloadServiceJobChangeAdapter extends
JobChangeAdapter
//////////////////////////////////////////////////////////// ////////////////

Hope this helps.

Just a side note ... if possible, be careful with getActiveShell() ...
content assist and those little transient javadoc popups are also
shells, and you wouldn't want to have it disappear on you. Sometimes
it's OK, but where possible perhaps pass in a solid shell ... like the
workbench window shell, that's it no likely to disappear on you (but of
course, you still have to be careful ... what happens to your Job when
someone closes your workbench window).
