#4260 — Exit desktop on Task Manager menu.

Is there any remaining reason for having the Exit Desktop entry on the 
Task manager menu? I write as someone who occasionally clicks on this 
by mistake instead of on Shutdown, resulting in an unusable screen.
Just wondering ...

With best wishes,

Peter.

I'm sure someone somewhere uses it to drop out of the Wimp and run their 
old Arthur era software, such as GraphicWriter.

You can get back in to the desktop with *desktop, then use shutdown so 
the Iyonix switches off.

You need to *configure the MonitorType, Mode and Sync settings 
correctly. Try 5, 28 and 0

Does not work on the ARMini as I just found out!

It is not working on Iyonix 5.18, It does work with RiscPC 5.19

Is their different functionality to using F12? 
Actually it looks a better option than using F12, as I often nudge
the F12 by mistake. Cntrl+F12 doesn't have the same problem,
maybe it is possible to map F12 to Cntrl+Shift+F12 to avoid this.

There's a module that transposes F12 and Ctrl-F12.. Since it's only 207
bytes large (shorter than the text of this mail), I dare to challenge the
netiquette and attach it here.

Put it into your !Boot.Choices.Boot.Tasks directory and enjoy the pleasure
of invoking the much appreciated task window with a single press on F12.

Kind regards,

In the past - did anyone do module - that brought up the 'taskwindow'
from 'adjust clicking' on the Task icon?

But it is the plain F12 that gets accidentally hit while going for the
backspace key, -if both Task and TaskWindow needed a combination, this
couldn't happen.

I guess one reason you might want to be still at your mouse after
opening a TW would be to position the newly opened window.Another
might be if you have !Typer or similar loaded with commands to
send to it by mouseclick.

I think Peters query(complaint?) about the 'Exit desktop' is
quite right, as it leaves you with a hung computer. Also it is very
close to the 'Shutdown'.

The 'Exit Desktop' does appear to be shutting things down properly
as I get a similar delay with a normal shutdown. I wonder if you
would be left with any network to use?

Depends on your keyboard :-)

This oldish Dell (AT102W) I'm using has a good keycap height spacing
between the number keys row and the function key row. Looking across at my
wife's keyboard the spacing isn't much different to that btween the other
rows.

Exiting the desktop just quits any Wimp Tasks and exits to the 
supervisor command prompt. All the underlying OS facilities are still 
available including networking.

Shutdown quits all Wimp tasks and stops at a shutdown screen. 
Additionally on the Iyonix, and other more recent hardware with power 
management, it turns off the machine.

But both with the Iyo and with this ARMini there's never any command 
prompt. Hence the original whinge from me!

I have just tried it on my Iyonix here (5.18 OS) and it seems to just
do a normal shutdown (including warnings about unsaved files etc). It
certainly didn't go to any star prompt. On a test of one sample, it
seems to completely mirror the normal C-S-F12 or Shutdown from the
menu. I guess mthe ARMini will be similar - I'll try it tomorrow.

Now, that's strange. I tried again. It did get to the supervisor
prompt this time (there were no interruptions this time with files to
save or messages from Alarm etc since I had just rebooted - does
cancelling these alerts cause it to restart the exit as a normal
shutdown?). However, trying to reenter the desktop resulted in a
freeze at the RISC OS Banner. Resort to Alt-Break gave a Data abort
type of error. Ended up having to use the reset button.

That's what I get on my BB -xM though if I kill 'Unknown' after the
Alt-Break and wait a long time it returns to the desktop with the pinboard
image absent & the files and applications set to run don't. Configure works
though.

The Iyonix stops at a grey screen and an active mouse pointer.
Both Access and Moonfish are still working at this point.
If these are Wimp Tasks then the 'Exit Desktop' isn't completing.
How do you draw the line between a Wimp Task and an OS facility?
I assume polling is a low level OS function that always happens.

Both Access and Moonfish have wimp front ends to allow connections to be 
established from the desktop, but the actual remote filing system 
functionality is provided by modules, and is active regardless of 
whether the desktop is running.

I refer you to the RISC OS Programmers Reference Manuals if you want a 
fuller explanation.

No, polling is purely a Wimp thing. Underneath RISC OS is a single 
tasking command line based OS, just like DOS.

Do the PRMs actually spell this out? ;-)


I would suggest that something that offers functional SWIs, *commands 
and maybe service calls is an OS facility.
If it multitasks, it is a wimp task.

While there is some crossover for OS facilities (*Filer_OpenDir, text 
editor as a relocatable module, etc), it is a pretty safe bet that 
anything that runs in the wimp is a wimp task.


Best wishes,

Rick.

Confusingly, *Wimptask <command> gives the appearance of singletasking
and all other wimp (desktop) activity appears to be frozen.
F12 also gives this impression.
Obviously they are single task interfaces to the user, but is there
still wimptask polling going on below?

I feel Networking is an example of multitasking (without the wimp),
As it can do several things at any time.
Access with one computer and NFS with another would have to be in
the multitasking category.
But if you started a network ftp or whatever in a taskwindow, then
left the Desktop with Exit desktop would the connection stay alive?

As before, what about *Wimptask and F12 prompt?

I dont have experience with *ShellCLI or Exit desktop(Supervisor?)
but it sounds like at least Supervisor has no wimptasks/polling.

I have found very little on *ShellCLI and that is why Steves alias
caught my eye.

A bit of experimenting may reveal the answers to some of my questions.

Thanks Ron M.

It depends upon the command. *WimpTask is for starting multitasking 
tasks. If you run a single-tasking program, then it'll act as such. 
It doesn't magically convert software to work in the desktop (that's 
what TaskWindow is for).

No. The desktop operates co-operatively. Simple experiment - run 
WebJames, fetch a largish file from another computer, and in the 
middle press F12 and watch the transfer cease as in the command line 
the desktop (and all multitasking) is frozen.

Really, if we had a half-decent TaskWindow, we could consign F12 as 
another anacronism of the past...

So could a filing system on a BBC micro. Don't confuse "runs on 
timers and interrupts" with modern multitasking. That sort of thing 
has been the mainstay of computing since the dawn of time (there's a 
hell of a lot going on *besides* your program, on any computer 
anywhere).

Networking and such is designed to tuck itself away into the 
background and just provide useful services, like the Freeway module 
recently discussed. Multitasking, the modern definition, is a 
collection of user-facing applications side by side.

Probably not, as surely that would terminate the TaskWindow?

It doesn't.

I think it is an internal mechanism to call the supervisor command 
line within a desktop environment without it all going tits up.

Me? I'd just look at the sources. ;-)

Has an overview of the command line from the User manual.
It appears that 'Supervisor' doesn't necessarily mean anything other
than an ordinary command line.
There is a Wimp$State variable that is either Desktop or Commands,
indicating that leaving the Desktop on it's own and you still have
Wimp activity.
The Exit option leaves the Desktop and additionally closes any tasks,
making it different to the F12 alternatives.
I'm guessing Wimp activity is still there with the Wimp$State set
to Commands.

Anyway, for the OP, something new I have come across during this 
thread, is that you can do a fast shutdown using CNTRL+SHIFT+F12.

And for Clumsy typist's that find the live F12 key upsets the flow,
It can be disabled by using

Set Alias$ShellCLI ""
  
The good thing is that CNTRL+F12 still works for a TW Command Line,
and full functionality can be turned back on with

UnSet Alias$ShellCLI

Thanks to Steve for showing the way to this tip, There are much
larger utilities around that dont do it any better.

That's about it, yes. I think it's a hangover from the 6502 machines.

In a manner of speaking. The Wimp is still "there" but it is 
inactive. Much like if you aren't currently riding a bike, the bike 
doesn't cease being. The Wimp activity will restart upon returning to 
the desktop environment.

I think the Wimp$State is to be checked so you don't try to 
initialise yourself as a Wimp task outside of the Wimp; but few 
bother doing that as most people work in the ooooh-clicky! 
environment anyway. ;-)


Best wishes,

Rick.
