You know when you want to update an area object, if you replace the 
text how do you make the cursor go to the home position? Outside 
of setting the para/scroll, there's some other value hanging around 
(I'm tired of looking for it with anamonitor!)

you may need to reset system/view/caret and face/line-info

Thanks. I thought you would know. You really have this stuff down, 
Gabriele.

Hi all, I want to launch a script from the command line using the 
-i option (to void the installation screen), something like

c:\> rebol.exe -i a-script.r


but the -i option only works if rebol is already installed , if is 
used after an uninstall (rebol -u) the install screen is shown.
is a known problem/bug?  someone known a solution? 
I'm using  view 1.3.2    win xp

ok, I need to play a bit more, the issue  happens just in few cases, 
I wil try to isolate the problem and then I'll be back with a new 
post

so, the issue is not only related to the -i option, but with launch 
function. 


if you start a rebol script from cli with -i option, and then the 
script launches a new process with launch function the  -i flag  
isn't passed to the new process, and the new process wil try to install 
rebol

i don't think launch will pass any arguments. you could try using 
call with system/options/boot

Experts;  What are the implications of removing  on-unfocus  from 
a face's flags block?  It has to do with a login panel firing on 
Enter (only) for the password field with a login button and some 
other fields that can cause an unfocus of the password (which by 
default fires the action...which can be inappropriate).

I think all the implications can be found in  system/view/screen-face/feel 
 (the global event handler).

I found this old article here about using user32.dll to control the 
mouse: 
http://www.rebolforces.com/zine/rzine-1-01/#sect6.1.
anybody tried to change mouse cursor with this?

yes.. what I know, Cyphre has working code for changing cursors... 
in R3 it will be possible without need to use the dll

Here's a handy-dandy little thing: http://rebol.hmkdesign.dk/vid-resize.r

Needs a bit of polish and some more testing, but it works.

router went down, sorry. link should be working now.

Is the only way to turn an image! into png with save/png ?

I believe so.

Hope we can fix this in R3.

Ie. have in memory transforms.

ah, yes that would be good for webserving.

made a better demo for vid-resize.r at the same url

have in memory transforms

 ... note that save accepts a target of type file!, url! or binary! 
 ... so you can always do:

	bin: make binary! 10000
	save/png bin load %test.jpg
	write/binary %test.png bin

good to know how this is done .. I have tried saving to binary! before 
without knowing how to do it!

I'm trying to add data to a drop-down widget, but I'm not able to 
get it to refresh to display the updated data list.

I've probed the /data-list and it shows teh new data. I then "show 
: the widget but no luck.

Also, when I clear fields of a form of which the drop-down is part, 
the item that was picked disappears from the drop-down list (but 
not the /daat-list its self.

;-- does this illustrate your setup?

view layout [
	dd: drop-down 150 "one" "two" "three"
	btn 150 "Add" [
		either tail? skip dd/list-data 3 [
			append dd/list-data ["four" "five"]
			face/text: "Remove" show face
		][
			clear skip dd/list-data 3
			face/text: "Add" show face
		]
	]

 btn 150 "Set" [set-face dd pick dd/list-data random length? dd/list-data]
]

hi guys ! 

i have a strange behaviour  when tracking events in feel/move func 
of my faces. 

I don't detect  events only when i entering or leaving the face (as 
expected).
Instead of that , i detect a flow of move events.

i must precise i don't use VID (where it works well)
I create my own layouts with make func.

!

hi all !
i try to detect move events in a feel/over func.

But i receive a flow of move events in my face instead of only 2 
events  (1 when entering, 1 when leaving).

I precise: 
I did'nt put the option [all-over] in the window.

I don't use VID but i construct my own layout with a serie of make 
face.

!*

!

arf, finally i can see my messages, sorry for the flood

Steeve, show us how you made the feel.

I suspect that you might have made the feel yourself using something 
like:
	feel: make object! [
		over: func [face over offset]
		...
	]

which would be wrong, as the view system is is sensitive to the order 
the words are defined in the feel object. The correct way is to make 
your feel from an existing feel, eg. 
	my-feel: make system/standard/face/feel [ ... ]

This ensures that the four feel functions are defined in the correct 
order in the object.

Making the object yourself, defining the functions out of order, 
explains why OVER sees events that normally appear in a DETECT or 
another function. I remember being quite confused by that.

If you make from another feel you don't have to worry about the order.

thanks Anton, i will test that soon

yeahaaaa ! it works well now, many thanks again Anton

chris, thanks for the help, nut my situation is a little different. 
I'm loading the data from a database. When I update the data base 
I read it again and store it in a word that I use to fill the drop-down 
with the "data"attribute. If I probe the word holding the updated 
database it shows the added data but the drop-down will not show 
the change.

EVen on your example above the drop down did not display "five"? 
I can not even scroll down to see it.  I had to increase the # of 
rows to se it   Bug?

Alan, show us some code. (try keep it small.)

I think I asked this a long time ago, but forgot the answer: Does 
anyone know how to detect when a window goes inactive?

Win32 API or View only solution? Dunno if it can be detected using 
View only ...

View only solution, if it's possible.

I don't care about other windows. I want to put up a warning that 
a window has gone inactive (critical that a text field is focused).

insert-event-func and watch for an 'inactive event I think.

Henrik, I think this was the best I could come up with:

http://anton.wildit.net.au/rebol/view/detect-all-windows-inactive.r

http://anton.wildit.net.au/rebol/gui/all-windows-inactive-handler.r

Would anybody have any clue where I could find this simple Rebol 
script demoing a shopping cart . I'm interested in the columnar hierarchical 
tree it used to navigate to the store's items. ?

Does the pen command of the draw dialect require tuples, or can we 
use 'red, 'blue and so on?

In View 1.3.1, 'red, 'blue and so on worked, but no longer...

actually, nevermind

something else is my problem

Here's my problem, from a new terminal session:


>> view layout [box 120x70 effect [draw [pen black polygon 0x0 119x0 
119x69 0x69]]]

>> view layout [box 120x70 effect [draw [pen black green polygon 
0x0 119x0 119x69 0x69]]]
Segmentation fault (core dumped)


..which should work fine, according to this Draw documentation:  
http://www.rebol.com/docs/draw.html#sect0.9.1.

If I recall correctly, that's a bug of View 1.3.1, specifying PEN 
with two colours.
