Rendering morph list items in NewList

Uko2
Hi,

when I use strings for list items of NewList - everything is fine, but if I use morphs - I get a strange artifacts if another window showers over them. Here is an example video: https://dl.dropboxusercontent.com/u/83145561/morphItems.mov

Maybe some morph gurus have an idea what’s wrong? For now I’ve discovered that all items render themselves with #listRenderOn:atRow:bounds:color:backgroundColor:from:

Cheers!

I can not reproduce this, how do you draw the items? Did you use NewListModel or do you use just NewList ?

Hello
I ve the impression that it is due to the redrawing of invalid rectangles. Maybe because of a lack of efficienty of the morph list

I use just NewList because I need a plain morph. For items I use a method like:

listItemFor: anObject
| listItem |
listItem := Morph new
“setup morph"
yourself.
“add submorphs"
^ listItem

Should I use another morph?

No, I still can not reproduce this one. Can you share your source?
