- I'm working on some drag 'n' drop stuff where I intend to use ghosting,
- a la File Viewer. I have an example app called ToolInspector that
- ghosts by compositing 50% NX_LTGRAY over the icon, and that's not
- bad. However, in studying File Viewer closely I've noticed that the
- ghosting behavior is more complex than that:
-
- 1. When dragging a file icon over an empty shelf slot, the ghosting
- leaves light gray and white alone, turns black into dark gray
- and dark gray into light gray.
-
- 2. A file that I have no permissions for appears on the shelf always
- ghosted, but differently than as described in 1.
-
- 3. I have access to a color machine, but I have no idea how to
- describe how the ghosting is done there, although there is still
- a difference between an icon being dragged over an empty shelf
- slot and an icon for a file I have no permissions to.
-
- I'm a compositing beginner, and I was not able to duplicate any of the
- above by experimenting with CompositeLab. Before I kill more brain
- cells trying to figure this out, does anyone know the rules for these?
- I'd like to have my ghosting behavior identical to File Viewer if
- possible.

- Thanx,
- Michael
