I've juste noticed the nice values we get for event key when pressing 
function keys !!!

in order: console listen tcp udp icmp dns local odbc oracle

is that 2.7? that is a bug, will be fixed in next release.

they should give f1 f2 etc of course :)

Hmmm, I've always gotten f1, f2, etc., though I don't use them much, 
so this may be new.

gregg, yes, they are supposed to be f1 etc.

I know they have been in the past.

there's a bug with 2.7 where event/key, when it should be a word, 
is wrong

that's probably because of the internal changes... probably wrong 
pointer or something like that

ins, del, home, end, pgup and pgdown have the same problem

1.3.2 is OK.

Ah, just 2.7 then; OK.

yep. the bug was introduced in 2.7

sorry... forgot to specify that its only 2.7 related... I just tought 
the values where funny... I assumed the break was that the keys didn't 
actually trigger... but then, on inspection... figured out what was 
really happening.

When is the next release, by the way ? I ask because we keep stumbling 
on this same bug, and I think it's an easy one to fix, judging by 
how fast those other string bugs were fixed.

i guess when Carl manages to escape from thread prison ;)

Does anyone know a way how to detect when all rebol windows are inactive 
(ie. because a non-rebol window became active) ?

I can trap inactive events sent to a rebol window, but I want to 
know whether that was because another rebol window was activated 
or a non-rebol application window was activated.

If it is a rebol window, that window gets an active event --- but 
this is *after* the previous inactive event.

another window in the same rebol process or a differen rebol process?

Same process.

I need something like a "none-active" event that lets me know when 
all rebol windows are inactive.

I would like to know that too. A program I'm making has a timer mechanism 
where the program must be active all the time and I want to display 
an alert if the window gets out of focus.

Maybe the system port ?

Let me dig around...

never messed with it

How many windows in your program ?

If only one, it's easy - just trap inactive event.

If more than one, and since you are running a timer, you can track 
the state of all windows and react when a timer event comes along 
after an inactive event which was not followed by an active event.

Probably that's my solution too - run a timer.

excellent, time events are still running even when all rebol windows 
are inactive. This means it's possible.

active-windows: []
insert-event-func event-func: func [face event][
	;print event/type 

 if event/type = 'active [if not find active-windows event/face [append 
 active-windows event/face]] 

 if event/type = 'inactive [if find active-windows event/face [remove 
 find active-windows event/face]] 
	if event/type = 'time [
		if none-active? <> empty? active-windows [
			none-active?: empty? active-windows
			if none-active? [
				print "all windows inactive!!"
			]
		]
	]
	event
]
view/new win1: layout [size 400x250]
view/new win2: layout [size 500x200]
win1/rate: 0 show win1 ; start time events
none-active?: false
do-events

Can you see any holes in this method ? (Apart from the fact that 
it requires time events.)

I discovered a problem when closing the first window which has RATE 
set. Now time events no longer flow and so the state isn't detected. 
But it is solved by catching the close event and setting RATE in 
a second window.

The above seems to be working satisfactorily. It has the limitation 
of setting the window/rate, though.

I handle this by patching the wake-event func and checking if the 
screen-face/pane has any faces within (which is the pane which holds 
the windows).  when ever this happens, it means all windows are closed. 
 and so I quit with none which disables the do-events.

obviously I verify after the part which handles any close event types, 
to make sure I trap any event which would have unviewed the last 
window or popup.

Seems like it should work Anton. Another way would be to catch the 
inactive event, set a "deadman switch" timer to go off shortly. When 
a window gets an 'active event, disable that timer.

oops... "so I quit with none" above should have read... "so I return 
with none"

hum. isn't it possible to have decimal rates?  I just tried using 
0.5 and am getting no 'time events. is this normal?

(v 2.7)

I believe it rounds them. If you want slower rates, use a time! value 
(e.g. 0:0:2 for every two seconds).

Maxim, catching all *inactive*, not simply closed.

Gregg, I'm working on that way now. For minimal impact, I only start 
time events if they aren't running already, and then I restore the 
window/rate after I catch the first time event.

This version uses the "deadman switch" timer idea and is working 
ok.

The reason I need this is for a pop-menu system (implemented with 
windows). When a completely different application window becomes 
active, I want to close all menues and submenues.

And it seems to be working for this application.. :) Now the long 
test...

oh no it's buggy. it works sometimes and sometimes not. Damn, time 
events are tricky.

ahhh didn't notice the subtility.

thanks gregg
