World: r3wp

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.

You are missing line-pattern in your code... this is working:

view layout [box 120x70 effect [draw [pen black green line-pattern 
1 5 polygon 0x0 119x0 119x69 0x69]]]

(anyway.. it's a bug.. which should be easy to fix I guess)

if you don't want to use line-pattern you should not use 2 colors 
for pen..

Darn..  =P   I was taking it as, for polygon, the line would be the 
first color and the inside would be the second.


Are there any more recent draw docs, then, so I don't get overly 
confused like this time?

but it is in the doc.. (the link above) If you want to make fill 
use fill-pen

...I was about to say, "then why is it called 'foreground' and 'background' 
color under pen?", then took another look - I somehow completely 
missed the last line under the "Pen" section...

Okay, just a lot of my mistakes..  ~innocent grin~

Challenge;  A REBOL face face.  Ok all you graphically inclined; 
come up with a face that is a face.

Given this graphically PT version ... what can you do to make the 
face of REBOL.

face-block: [
    pen blue ellipse 150x150 100x120           ; head

    fill-pen green circle 110x110 10  circle 190x110 10             ; 
    eyes
    fill-pen black circle 110x110 3  circle 190x110 3
    fill-pen pink ellipse 150x150 10x20        ; nose
    fill-pen red ellipse 150x200 25x10         ; mouth
]


view layout compose/deep/only [box 300x300 sky effect [draw (face-block)]]


Extra points for blinking, winking and moving lips, but simple is 
better  - plans is to show students.  :)
(For those that need to know ... PT is short for part-tard).

hoping for some help. I copied my desktop view install to a usb pen 
drive for my laptop and made the mistake of not doing an install 
so now it does not see my local dir.I used regedit to delete all 
calls to view I could find rebooted and still the same problem :( 
Any hints ? Thanks !

What happens if you actually do an install?

Is http://www.rebol.com/docs/easy-vid.htmlthe only documentation 
from REBOL Tech we have for vid  ?

Surely not - there is at least one other ...

and also very precise View documentation - just go to rebol.com docs 
section
