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

Er, sorry, I did not describe what I am doing correctly. Let me try again:
try {
IRunnableWithProgress runnable = makeRunnableWithProgress(...);
PlatformUI.getWorkbench().getProgressService().
busyCursorWhile(runnable);
} catch (InvocationTargetException ite) {
logError(ite.getCause());
} catch (InterruptedException ie) {
; // since 'cancel' == false, this should never happen
}
// and then, the body of the method makeRunnableWithProgress() is:
return new IRunnableWithProgress() {
public void run(final IProgressMonitor monitor)
throws InvocationTargetException, InterruptedException {
if (null != monitor) {
String msg = ...;
monitor.beginTask(msg, IProgressMonitor.UNKNOWN);
}
try {
myLongTask();
} finally {
if (null != monitor) {
monitor.done();
}
}
}
};
