Well, here it is. I've touched it up a bit since Perry and I
originally put this together, I hope everyone likes it. It's
something I've wanted ever since I got my machine and ever
since I read Andy Hertzfeld's quote about Amiga windows...
Well Andy, now what do you have to say? :-)

03/18/87 DropCloth 1.0 by Eric Lavitsky/Perry Kivolowitz
DropCloth (tm) is an enhancement for your WorkBench. The original
functional program was written in one all night hacking session
on February 8, 1987 by Eric Lavitsky and Perry Kivolowitz.
DropCloth replaces the standard blank WorkBench backdrop with a
pattern. DropCloth will only run with the WorkBench up, and will
properly refresh the WorkBench screen when icons are moved.
To use DropCloth from the CLI, type:
DropCloth nn ... or
Run DropCloth nn
where nn is a number between 0 and 64. The number specifies the
intensity of the pattern used for the backdrop, 0 will render
nothing into the display while 64 will render a solid backdrop.
If you don't specify a number, DropCloth will default to 32.
Experiment and have fun!
DropCloth opens a window in the upper right hand corner of the
WorkBench screen. The window cannot be depth arranged, is only as
tall as the screen title bar and cannot be resized. To close
DropCloth, click on the close box in the DropCloth Window.
When DropCloth is running, you will lose some memory that the
system uses to create backup areas or "scratchpads" for the
WorkBench screen when DropCloth is run - all the memory will be
recovered when you exit DropCloth. The program has never been
tested with MoreRows, but we believe it will work with it.
DropCloth may also impact WorkBench preformance - note how a delay
is introduced from the time you select an icon to the time the
icon becomes highlited or active when DropCloth is running.
Windows may also be redrawn at a slightly slower rate while the
system reconstructs the newly exposed pattern areas on the
WorkBench backdrop. It is up to you to choose between the nice
patterned display or the slightly better preformance/memory use.
Please note that DropCloth is not public domain, but may be freely
distributed by anyone so long as this message remains intact with
the distribution. DropCloth remains the property of ASDG and may
not be sold for profit. Feel free to send me bug reports and I'll
try and figure out what's going on.

The dropcloth looks neat. Thank you
However, when I close a window, the dropcloth did not refresh.
Is that a bug or a feature?
By the way, I was running on 1.1. Was it the problem?

Well, you could use the background run program that Rob Peck wrote - I believe it was recently reposted to the net. If you don't have it, I could mail you a uuencoded binary (or the source, whichever you prefer). Then you can run DropCloth (and other things) from the startup-sequence and close the original CLI window...

[-------------------------------------------------------]
Assuming you're going to open a new cli window in your startup
sequence, you can put "run dropcloth" and/or "run foo" in s file, and
use the "from" option when you open the new cli window. Of course,
then you won't be able to close *that* window, but you'll have no
trouble closing the main window. This works for what I want to do,
but the run-in-background program Eric mentioned sounds good too.
Could someone email it to me? Thanks, Ken

The reason the old cli won't go away from startup-sequence is that you have spawned a process that needs to point back to that console's control structures (the Process structure and the CLI structure, as I recall). There is a way around it, but only if your program DOES NOT DO ANYTHING WITH STDIN OR STDOUT. The correct way to specify (at least under 1.1... I'm writing this from memory and don't have the Amiga here) in the startup sequence is: RUN > NIL: < NIL: YOURPROGRAM > NIL: < NIL: or RUN TO NIL: FROM NIL: YOURPROGRAM TO NIL: FROM NIL: This disconnects a lot of stuff from the originating CLI and lets the startup CLI window close down, with just your program running on the workbench. From a program that DOES require CLI input, another program can be spawned using the Execute function of AmigaDOS, such that when the originating program closes down, the window can go away, even though the program has started. Use the exact same string as shown above, but this time in the Execute function. I forget, but it may also be necessary to pass in a handle to NIL: (my notes are at home... this stuff almost made it into the Prog. Guide, but not quite). struct FileHandle *fh; fh = Open("NIL:",MODE_NEWFILE); /* (check the mode, memory again) */ success = Execute(" that-very-same-string ", fh, fh); Close(fh); /* now go away */ If I recall correctly, using Execute("string",0,0) leaves you with the same problem as initially reported (cannot close down the originating CLI) because the 0,0 causes stdin and stdout to be passed to the spawned process, whether it needs it or not. Anyway, hope this helps. Rob Peck hplabs!dana!rap

I'm writing this from memory and don't have the Amiga here) in the startup sequence is: RUN > NIL: < NIL: YOURPROGRAM > NIL: < NIL: or RUN TO NIL: FROM NIL: YOURPROGRAM TO NIL: FROM NIL: This disconnects a lot of stuff from the originating CLI and lets the startup CLI window close down, with just your program running on the workbench. From a program that DOES require CLI input, another program can be spawned using the Execute function of AmigaDOS, such that when the originating program closes down, the window can go away, even though the program has started. Use the exact same string as shown above, but this time in the Execute function. I forget, but it may also be necessary to pass in a handle to NIL: (my notes are at home... this stuff almost made it into the Prog. Guide, but not quite). struct FileHandle *fh; fh = Open("NIL:",MODE_NEWFILE); /* (check the mode, memory again) */ success = Execute(" the-above-mentioned-string ", fh, fh); Close(fh); /* now go away */ If I recall correctly, using Execute("string",0,0) leaves you with the same problem as initially reported (cannot close down the originating CLI) because the 0,0 causes stdin and stdout to be passed to the spawned process, whether it needs it or not.

The reason the old cli won't go away from startup-sequence is that you have spawned a process that needs to point back to that console's control structures (the Process structure and the CLI structure, as I recall). There is a way around it, but only if your program DOES NOT DO ANYTHING WITH STDIN OR STDOUT. The correct way to specify (at least under 1.1... I'm writing this from memory and don't have the Amiga here) in the startup sequence is: RUN > NIL: < NIL: YOURPROGRAM > NIL: < NIL: or RUN TO NIL: FROM NIL: YOURPROGRAM TO NIL: FROM NIL: This disconnects a lot of stuff from the originating CLI and lets the startup CLI window close down, with just your program running on the workbench.

Is the source to DropCloth available? It's cute, but a little annoying. It would be much more pleasant to the eye if you could put an image in there... or just 2x1 halftoning instead of 1x1. I seem to recall seeing it on the net. -- -- Peter da Silva `-_-' ...!seismo!soma!uhnix1!sugar!peter (I said, NO PHOTOS!)
