Dustbin
© Alan Donovan 1993
Possible Future Version Alterations:
===================================
1) Compress the BASIC RunImage to save space, and
remove unnecessary arrays etc.
3) Try to trap fatal error arising when a file too
large to fit in dustbin is dropped on it from
another disc - it's a "Disc Full", but nearly
impossible to trap.
Development History:
===================
v2.65 Filer_action task now transfers all rubbish to a subdir,
'Delete', where it removes everything. This allows the
dustbin to be used IMMEDIATELY after emptying has been
initiated. The real reason that this very slightly crap
solution was used is because I don't know anything about
filer_action tasks and can't get my hands on the PRMs.
v2.60 Finally uses a Filer_Action task for the 'empty' option,
thus allowing abortion in mid-delete. However, it does open
a parallel window for every file deleted: much simpler to
use one task that deletes every file serially.
v2.50 Bug removed: multiple file drops used to cause errors
as the dustbin was first cleaned of objects with matching
names. Plus Wimpslot reduced. Also var_val routine
improved.
v2.41 Message window now re-centres itself when it is
opened.
v2.40 Icon changes (full to empty, etc.) improved and
updates more regularly: implemented by 'Needs Help'
and proper indirection of iconbar sprite.
v2.30 The Dustbin now bulges to show that it is not empty.
v2.23 Minor bug fix - less window-swapping when emptying.
v2.21 Minor bug fix - FNread_var_val($) routine wasn't working.
v2.20 Now there is the option for Backdrop (à la Mac) Icon Bar
Dustbin operation, by use of a variable "icon_bar%" in
the !RunImage file at the beginning.
v2.15 Removed 'Bad Rename' error which occured when ...$path
type filenames from other filing sytems were used. This
was not satisfactorily dealt with in v1.50. The Dustbin
now runs off any filing system with no alteration -
previously it worked only on a Watford ide hard disc.
v2.10 Now uses only 1 window instead of 3 for the confirm, move
and empty dialogues.
v2.00 Now runs off the backdrop like on the Apple Mac. The
reason that the pale-grey border surrounds the icon is to
make it contrast with the background - anyone care to
make a high-contrast sprite?
v1.50 Several bugs connected with the file transfer corrected -
most noticeably the 'Bad Rename' error encountered when
using ...$path type variables that were on a seperate FS
from the dustbin, and when trashing the dustbin itself.
v1.00 first version - worked... barely.
