What controls the location of the trash icon on the desktop?
Where are the coordinates stored for that icon?
How can they be modified?
Thanks.

The offset of the upper-left corner of the Trash icon with respect to this point is stored in the last four bytes of CODE segment number 3, that is the one called "Init". (I only looked at version 6.1 of the Finder. I don't know about older versions.) More explicitely (on my SE): y coordinate x coordinate ============ ============ lower-right corner of the screen: 342 = $0156 512 = $0200 last four bytes of CODE resource 3: -58 = $FFC6 -56 = $FFC8 ------------ + ------------ + upper-left corner of Trash icon: 284 = $011C 456 = $01C8 Notice that both offsets are negative, and that the vertical offset is stored first (because that is the proper order for Points). I hope this helps. Greetings, Freek "Digitalistengebroed" Wiedijk Path: uunet!fwi.uva.nl!freek #P:+/ = #+/P?*+/ = i<<*+/P?*+/ = +/i<<**P?*+/ = +/(i<<*P?)*+/ = +/+/(i<<*P?)**
