You may have guessed I hadn't used Jobs much before.
Then I was surprised that I couldn't find much about Jobs in either��
Pharo By Example, Deep Into Pharo or Enterprise Pharo.

From digging around I made a minimal example I report��
to help others' searches, and open it for improvement.

x := 1.
[
[x < 100] whileTrue:
[ x := x + 10.��
0.1 seconds wait.
]
] forkAt: 30 named: 'worker'.��

[ :job |
[ x < 100 ] whileTrue:��
[ job current: x.
0.1 seconds wait.
]
] asJob��
�� title: 'Work progress...';
�� min: 0;
max: 100;
run.

Ben,

You disappoint me, as I would expect you to trace senders/users of #signalProgress: ;-)

:P��
Yeah I knew I was being slack.�� I couldn't really follow its operation and was a bit tired.
Actually maybe part of my confusion is that #signalProgress feels more like a command than a status.
I've a slight feeling it would be better as #signallingProgress.

ZnClient only signals certain Notifications which a UI around it should deal with.

For example,

[ :bar |
�� bar title: 'Downloading Sources...'.
�� [
�� �� ZnClient new
�� �� �� url: 'http://files.pharo.org/sources/PharoV30.sources';
�� �� �� signalProgress: true;
�� �� �� downloadTo: FileLocator temp ]
�� �� on: HTTPProgress
�� �� do: [ :progress |
�� �� �� progress isEmpty ifFalse: [ bar current: progress percentage ].
�� �� �� progress resume ] ] asJob run.

Thanks, that worked, but its a bit convoluted for my goldfish memory to remember each time.
I'd expect having that as a convenience method would be useful to many.

ZnClient��
showProgress: 'Downloading sources...'
during: [ :znClient |��
znClient downloadTo: FileLocator imageDirectory ].��

ZnClient class >> showProgress: title during: clientBlock
|client|
client := ZnClient new.
client signallingProgress: true.
[ :bar |
�� bar title: title.
�� [clientBlock value: client]
�� �� �� on: HTTPProgress
�� �� do: [ :progress |
�� �� �� progress isEmpty ifFalse: [ bar current: progress percentage ].
�� �� �� progress resume ] ] asJob run.

Easily discoverable as the only class-side method of ZnClient,��
and this would also make a useful howto reference.��

��
But there are other UI approaches as well.��

Sven

Thanks for you prompt response.
