WinXP; R3.3
I seem to recall that there is already some way to get the following
behavior in Eclipse (but searching the help and these newsgroups turned
up no answer):
I have a long-running operation, which in some cases will complete in
(say) 1-2 sec, and in others will complete in more like 30-60 sec. It
has not yet proven possible to compute, in advance and reliably, how
long a given case will run.
So I would like to have the busy cursor appear, and then (if the
operation lasts longer than some time), to have the progress-monitor
dialog open.
I know how to do the first:
BusyIndicator.showWhile(someDisplay, someRunnable);
And the second looks like this:
try {
new ProgressMonitorDialog(someShell).run(false, false,
someRunnableWithProgress);
} catch (InvocationTargetException ite) {
logError(ite.getCause());
} catch (InterruptedException ie) {
; // since 'cancel' == false, this should never happen
}
Is there any built-in Eclipse way? Or is it a matter of my writing a
multithreaded timer, that monitors a Job, and then creates the
ProgressMonitorDialog on the fly if more than the specified time has
gone by?
thanks,
Paul

There seems to be something wrong in your code.
You wrote you are calling busyCursorWhile INSIDE your run method?
Your code should look like the following:
IRunnableWithProgress myRunnableWithProgress = new IRunnableWithProgress() {
public void run(IProgressMonitor monitor) {
monitor = (monitor == null) ? new NullProgressMonitor() : monitor;
try {
monitor.beginTask(...);
...
} finally {
monitor.done();
}
}
};
PlatformUI.getWorkbench().getProgressService().
busyCursorWhile(myRunnableWithProgress);
