I'm working on my AttachmentMorphs, and am trying to add a mode where they won't be visible unless the mouse is over them.

But using mouseEnter: and mouseLeave: to control visibility doesn't work, since the mouseOver logic in the Hand ignores invisible Morphs.

I guess I could use step and query the cursor position every time, but is there a cleaner way?

(Actually, using step would let me make them visible when the mouse was merely near them. This might be better).

Ned -

You might want a global command (like to any pasteUp or the world) to make all attachers visible. I only mention this beacuse of, eg, the make-visible command in many text editors that lets you see all non-printing characters. This means you needn't be bothered by the attachers when you don't want them, and you don't have to fish for them when you do.

Mouse-over and proximity are certainly equally reasonable preferences to play with, though.
