Besides creating morphs according to the current preferences, we should<br>
think about how to update existing instances. For colors, there is<br>

#updateInstances. There is also ScrollBar class >> #refreshAllScrollBars.<br>
But this is rather specific and not reusable without carefully<br>
copy-and-paste. They make use of #allSubInstances -- is this the best way of<br>
doing it?<br>
<br>
Coming back to the original problem in this thread: Yes, we should add a<br>
preference to specify the background color in lists, trees, and text fields.<br>
Should be easy. :)<br></blockquote><div><br></div><div>Sounds promising ;-)</div><div><br></div><div>Best,</div><div>Karl </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
