Thanks, Bob. I'll try the occasional approach. That indeed seems to do what I want.<div class="gmail_extra"><br><br><div class="gmail_quote">On Thu, Nov 15, 2012 at 5:40 AM, Bob Arning <span dir="ltr"><<a href="mailto:arning315@comcast.net" target="_blank">arning315@comcast.net</a>></span> wrote:<br>

<div> thanks, but no thanks <blush>. I want to see the
update as fast as possible, even if it flickers like crazy. I
don't want to display the whole world, just the text morph in
question. </div>

<div> I submitted a run until feature for the
debugger to the Squeak inbox recently and would
commit it to trunk except that I'd like the option
of having the selection update on each step. But
I can't see how to do that. I *think* selection
update is done with a callback here in
Debugger>>contents:selection:</div>
<div><br>
</div>
<div>
<div><br>
</div>
<div><span style="white-space:pre-wrap"> </span>Smalltalk
isMorphic ifTrue:</div>
<div><span style="white-space:pre-wrap"> </span>[World</div>
<div><span style="white-space:pre-wrap"> </span>addAlarm:
#changed:</div>
<div><span style="white-space:pre-wrap"> </span>withArguments:
#(contentsSelection)</div>
<div><span style="white-space:pre-wrap"> </span>for:
self</div>
<div><span style="white-space:pre-wrap"> </span>at:
(Time millisecondClockValue + 200)].</div>
</div>
<div><br clear="all">
<div>And I'm not sure how this causes the
selection to update. Is it part of text morph
draw or a separate thing? This is too
convoluted to look through. So perhaps someone
can help e. If I want the selection to redraw
what's the minimum action necessary. This is as
part of a loop that looks like</div>
<div><br>
</div>
<div>
<div><span style="white-space:pre-wrap"> </span>[self
selectedContext == context</div>
<div><span style="white-space:pre-wrap"> </span>
and: [(value := receiver with: context
executeMethod: method) == false]] whileTrue:</div>
<div><span style="white-space:pre-wrap"> </span>[self
doStep].</div>
</div>
<div><br>
</div>
<div>i.e. after the doStep I'd like to force the
code pane to update its selection.</div>
