<div dir="auto">I think the redrawNeeded is there to force the target morph to redraw, and since it now has a halo the canvas will draw the coordinate system. But I don’t understand why it has to be made like that, why does the canvas have to know anything about halos, why cant HaloMorph draw the coordinate system instead?</div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, 4 Apr 2021 at 10:58 PM Pat Foley via Cuis-dev <<a href="mailto:cuis-dev@lists.cuis.st">cuis-dev@lists.cuis.st</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)">One more point I hadn't checked before:<br>

If you go ahead and apply 4548, and then in a workspace do<br>
<br>
w _ TheWorldMenu new buildWorldMenu.<br>
w popUpInWorld addHalo.<br>
<br>
then the halos are in the right place to start with, but unresponsive.<br>
<br>
So I guess next is to look at what makes halos act like halos?!<br>
