- TrashIcon V2.2 © 1993 Mark McPherson
- =======================================
-
- Overview
- ========
-
- TrashIcon is a program which places an icon on the WorkBench, and will
- delete any files dragged to that icon by the user - ie it uses the WB2
- feature of AppIcons. Because of this it will only work under WB2.04 and
- above.
-
- The standard trashcan in use on the Amiga has several difficulties. It
- can only delete files on the disk containing the trashcan, and also doesn't
- delete files immediately. TrashIcon overcomes these difficulties.
-
- TrashIcon is highly configurable and gives the user great flexibility
- over what is deleted. It will, unlike some other similar programs, keep
- the WorkBench in step with what you are deleting. You can also format disks
- either quickly or fully.
-
-
- Distribution
- ============
-
- All code is Copyright © 1993 Mark McPherson. It may be copied and
- distributed so long as no commercial profit is made out of it. it may not
- be modified, sold, or included in any commercial distribution without my
- written permission. Public Domain vendors are not allowed to sell this
- program for more than the price of a regular disk, which should be no
- more than the equivalent of 5 Dollars. The author takes no responsibility
- for any loss or damage resulting from the use of this program.
-
- This distribution should contain the following files:
-
- TrashIcon
- TrashIcon.info
- TrashIcon.doc
- TrashIcon.doc.info
-
- though they may of course be archived with a program such as LhA.
-
-
- Installation
- ============
-
- TrashIcon works best when started from the WBStartup drawer of your
- boot disk. It can also be started simply by double clicking on the
- TrashIcon program icon. It should not be started from the CLI.
-
- To automatically run, simply copy the program and its icon to the
- WBStartup drawer. Otherwise just copy them to where you want the program
- to reside. Make sure that the program and its icon stay together else
- TrashIcon will most likely fail to work. You can copy the documentation
- to anywhere you like, or simply deleted if you never want to use it again.
-
-
- Usage
- =====
-
- TrashIcon has many different features available making it flexible
- and configurable to how you want to use it.
-
- The icon that is placed on the WorkBench is simple the program icon,
- and may be changed if you don't like the icon supplied. All of the
- program options are set by the icon's ToolTypes, but can be changed and
- set completely from within the program. The position of this icon can be
- set on the WorkBench if you want.
-
- The main use of TrashIcon is obviously to delete files. This is done
- by dragging an icon (or selection of icons) of the objects to delete, to
- the icon on the WorkBench. If you drag a disk icon to TrashIcon, then
- you will be given the option of formatting that disk. You can choose, if
- the confirm option is set, to delete some or all of the files you have
- dragged. If you drag a drawer, you can choose to delete both the drawer
- and all its contents or only delete it if it is empty. Some files may be
- protected from deletion and you can choose whether you want to delete
- these automatically, not delete them, or be asked whether you want to
- delete them.
-
- By double clicking on the TrashIcon icon, you will bring up an options
- window where you can change the current settings of the program. You can
- also make these changes permanent or simply temporary, or even forget them.
- Repeatedly double clicking on the icon will close and reopen this window.
- Note that while this window is open you can still drag icons to be deleted
- to the TrashIcon on the WorkBench, or even drag them into the window itself.
- It is this feature which is one of the major differences between this version
- of TrashIcon and earlier versions, or other similar programs.
-
-
- Options
- =======
-
- TrashIcon has many different options, all of which may be changed from
- its options window. Each option is detailed below.
-
- The window itself is controlled by clicking on the buttons marked:
-
- QUIT - this will cause TrashIcon to finish all deletion of files
- and then close the window, remove the icon, and quit.
-
- ABOUT - this will bring up an "about" requestor with details about
- the version of the program etc.
-
- USE - this will close the options window, retaining any changes
- to the current options that you have set.
-
- SAVE - this will cause the current options to be saved, so that the
- next time TrashIcon is run, those will be the default options.
- It also saves the current position of the options window. This
- is all done by setting the ToolTypes of the program icon. You
- should never have to set these manually, except to add those
- such as DONOTWAIT which are used by the WorkBench and
- not TrashIcon. Clicking on this button will also close the
- options window.
-
- CANCEL - this will close the options window and revert to the original
- settings before the window was opened.
-
-
- Icon X Position - this is the horizontal coordinate on the WorkBench
- of TrashIcon's icon. If something else occupies
- this position then the WorkBench will decide where
- to put the icon.
-
- Icon Y Position - same as above, but for the vertical coordinate.
-
- Icon text - this is the text that appears below the icon on
- the WorkBench. It defaults to the program name,
- but can be changed to anything else, including
- a blank name.
-
- Open Window - if this is set, then when the program is started,
- the options window will open immediately.
-
- Ignore Protection - this is set to what should happen if you try to
- delete a file that is protected from deletion.
- if set to ASK, then you will be given the option
- of deleting the file. If set to YES, then such
- files will always be deleted. If set to NO, then
- such files will never be deleted.
-
- Recursive Delete - if this is set, then when you drag a drawer to
- TrashIcon, both it and its contents will be
- deleted. If not, then the drawer will only
- be deleted if it is empty.
-
- Confirm Deletion - if this is set, then before any deletion takes
- place, you will be given the choice of either
- continuing (OK) in which case the deletion will
- take place as normal, stopping (CANCEL) and not
- deleting anything, or CONFIRM EACH where you
- will be asked before deleting every file. If
- CONFIRM EACH is selected, then for every file you
- will be asked if you want to delete that file and
- continuing (YES), deleting that file and every one
- after it without any more prompting (ALL), not
- deleting that file and continuing (NO), or stopping
- at that point (NONE).
-
-
- Technical Notes
- ===============
-
- To delete a particular file, TrashIcon goes through the following steps:
-
- - it will first check if the file has an icon.
- - if so then it will delete the file and its icon.
- - if it is a drawer, and WorkBench has its window open, then TrashIcon will
- first delete the icon in order to get WorkBench to close the window. It
- will then try to delete the drawer. If it still can't delete the drawer,
- then it will put the icon back.
- - if the file has no icon or if it is an icon with no associated file then
- it will delete this.
- - if the object is a drawer icon but there is no associated drawer, then
- TrashIcon will open its options window. This isn't a bug in TrashIcon,
- but an unfortunate side-effect of the way WorkBench tells TrashIcon what
- to delete. Note that many other programs have similar behaviour.
- - if an object cannot be deleted, then neither will its icon.
-
- REMEMBER: that non-empty directories cannot be deleted. eg, if a file
- in a directory is locked for some reason and cannot be deleted,
- then the directory will not be able to be removed - not even
- with the Recursive Delete option set.
-
-
- The History of TrashIcon
- ========================
-
- TrashIcon has had many different versions - some of which have been
- released, some of which haven't. Public release means that I have
- distributed that version properly. Semi-Public release means that I
- have freely given copies of the program to people, but haven't actually
- released it properly. Internal release means that only I and a couple
- of close friends have used that version.
-
- V0.1 - 15/01/93 Internal release
- The first version of the program. Had an appicon and could
- recusively delete files, but had no options window. It also
- didn't update the WorkBench in all cases.
-
- V0.5 - 20/01/93 Internal release
- Added an options window. Could now override the protection on
- files.
-
- V0.6 - 20/02/93 Public release
- Made the position of the icon user-definable. Also added initial
- confirmation of deletion of files. Wrote some documentation!!!
-
- V1.0 - 22/02/93 Internal release
- Added purge option for wiping a file completely.
-
- V1.1 - 24/02/93 Internal release
- Fixed a minor bug in the options window, and made the purge option
- even more secure.
-
- V1.2 - 26/02/93 Public release
- Totally removed purge option due to finding MAJOR unreliability in
- the method used. Decided that I wouldn't implement this until there
- was a fool-proof method available. Added extra confirmation handling,
- and the ability to format disks.
-
- V1.3 - 28/02/93 Semi-Public release
- Changed the deletion code significantly and fixed a couple of minor
- bugs in the process.
-
- V1.4 - 13/05/93 Public release
- Note the time lapse - I had exams!!! Removed all Enforcer hits.
- Unfortunately, this version has a VERY large bug which I didn't spot
- until too late. This version been put on a Fred Fish disk - I hope
- nobody uses it!
- 10/9/93 - Amiga Shopper reviewed this version and gave it 9/10. Do
- they really test the programs they review???
-
- V1.5 - 27/05/93 Public release
- Fixed the bug in V1.4. Added the Icon Text option.
-
- V1.6 - 23/06/93 Public release
- Completely rewrote the file deletion routines. This version keeps
- WorkBench in step with deleted files MOST of the time...
-
- V2.0 - 01/07/93 Semi-Public release
- Code was rewritten from scratch. The options window was made into
- an AppWindow so that files could be dragged to it as well as the icon.
- Also made ALL the options changeable here. Up until now, options could
- only be set by changing the program icon's ToolTypes. Made the program
- multitask while formatting a disk. The delete routine now ALWAYS keeps
- WorkBench in step with it. All these new options and TrashIcon has
- actually got SMALLER!
-
- V2.1 - 12/09/93 Semi-Public release
- Changed the way in which deletion of .info files without a program
- file was handled. This makes the program run faster and also makes
- the code tidier, but does make the program a few bytes larger ;o)
-
- V2.2 - 29/09/93 Public release
- Made changing the icon's positioning and text occur when USE or SAVE
- is clicked on. These only worked when first running TrashIcon in earlier
- releases. Also changed the SAVE routine - making it smaller, more
- efficient, and more importantly removing a (possible) bug. The program
- is now even smaller than V2.0!
-
-
- Thanks and Testing
- ==================
-
- This version of TrashIcon has been tested under V37.175, V39.106 and
- V40.003 of the Operating System, on both accelerated and unaccelerated
- machines. I have yet to test it on an '040 machine since I don't know
- anybody with one! It should work on one OK though. It definitely works
- on A500's, A600's, A2000's, A1200's, A3000's and A4000/030's.
-
- I have had a lot of people saying that TrashIcon doesn't seem to work
- properly when deleting from the RAM disk. I don't know why this happens,
- especially since I do most of my testing in RAM: (for obvious reasons!)
- If it DOES happen then send me a report specifying your setup and the
- circumstances in which it happened (a snoopdos or similar program's report
- would be handy!)
-
- In all testing I must say thank you to Matt Jennings for allowing me to
- use his Amiga 3000. Without this, finding and removing Enforcer hits would
- have been nearly impossible! Thanks also to everybody who wrote to me
- and told me what bugs there were. I'm pretty sure that this version is
- finally bug free, but who knows ;-)

- About the Author
- ================
-
- Hi! TrashIcon was written by me, Mark McPherson, in my spare time
- while studying for a BSc in Compter Science at the University of Kent
- at Canterbury, in England. I have never asked for money for this program,
- but have on one occasion been sent some! I like to hear from all people
- who use this program, and any suggestions on how to improve it are
- welcomed. When I started on this project, I simply wanted a small but
- fast program that deleted my files! All the other similar programs
- around simply didn't do what I wanted, or were ridiculously large for
- what they did. TrashIcon finally does everything that I want it to
- do, but I will continue to support it and update it if there is a need.
-
- I can be contacted on the Internet by E-Mail at "msm@ukc.ac.uk", so please
- send me some E-Mail if you can. For those of you without such access,

-
- Note that if you want the latest version of this program then either
- contact me via E-Mail and I'll send you the latest version, or send me a
- blank disk and the cost of return postage, and I'll post it to you.
-
-
- Anyway, I hope you like this program.
