<pre wrap="">Hi Bob,
Thanks for the answer. I will give:
self changed.
a try tomorrow. #stepTime returns 1000. The code is called every second. I have checked with
messages to the transcript. The method #displayDateTimeHeader is called every second. It
clears the area. Most of the text is repeated until the minute changes but the seconds change
with every call. I don't understand why it doesn't redraw. I may be breaking some rule with
how the morph is defined. If so, I'm not sure what it is. If sending self changed doesn't
work, maybe I will post a fileout of the whole morph, if you would be kind enough to take a
look.

<pre wrap="">Morphs redraw when something has changed -- not much point in wasting
cycles if everything is the same. So somewhere, like the Calendar... or
an inner morph that only contains the time needs 2 methods like:
step
self changed
stepTime
^1000 "or less"

<pre wrap="">Hi All,
I'm making a CalendarDisplayMorph. The code below is called every second. I'm sure it is
being called every second. But the seconds don't change every second. It does change if I
click on the morph and select or move it or something.
I'm testing it with this:
(TransformationMorph new asFlexOf: CalendarDisplayMorph new) openInWorld.
What am I missing?
