Ok. I guess backgroundColor is a breeze. I got that working, and using a
little logic from your examples, I have the selection and highlight
colors showing.
This is only a third of the problem though, and the easy third I think.
If I'm thinking about this right, the List, for example, handles the
highlight and selection drawing itself? Not the individual renderers?
I've looked at the code for the default TreeItemRenderer and
ListItemRenderer and they don't do anything with highlighting and
selection colors. So to do what I want to do can I turn off the List's
highlighting and selection stuff, and handle it all in the itemRenderer
via changing the background color based on the isSelected and
isHighlighted bools?
I guess that will work, but seems hacky. I just wanted to:
setStyle("selectionColor", color);
setStyle("highlightColor", anotherColor);
Guess I'm pipe dreaming.
Thanks for the ideas.
