It's handled in the TreeView.  There's really no nice way to handle it
from there, though.

If it's a controlled environment, I can think of a kind of ugly
approach.  First, change the theme's selection color to be the same as
the bg color.  This will make it look like nothing is selected.  Then,
write custom cellrenderers that handle selection themselves.  You are
passed in the selected state in the flags argument.  You can then draw
the selection image of your choice.

Good Luck,
