I found a script in www.rebolforce.com with a new widget : the dropdown widget.
The code of this widget is :
dropdowns: stylize [
dropdown: text
black white 100 edge [color: 110.120.130 size: 2x2 effect: 'ibevel]
font [shadow: none]
middle
with [
list-lay: none
show-arrow?: true
rows: 4
size: 100x24
line-list: action: none
list-data: copy []
dd-feel: make face/feel [
over: redraw: detect: none
engage: func [face action event][
switch action [
time [if not face/state [face/blinker: not face/blinker]]
down [face/state: on]
alt-down [face/state: on]
up [if face/state [face/show-dropdown] face/state: off]
alt-up [if face/state [do-face-alt face none] face/state: off]
over [face/state: on]
away [face/state: off]
]
show face
]
]
arrow-button: does [
layout [
origin 0x0 arrow down [self/show-dropdown]
edge [color: 110.120.130 size: 2x2 effect: 'ibevel] 128.128.128 14x20
]
]
show-dropdown: func [/local tl picked][
if not list-lay [
list-lay: layout [
origin 0x0 at 0x0
tl: text-list data self/list-data bold to-pair reduce [size/x
rows * 15 + 4]
self/font/color self/color
[ self/data: self/text: value show list-lay
wait 0:0:0.03 ; long enough to see selection
hide-popup show self
]
do [if picked: find self/list-data self/text [append clear
tl/picked first picked]]
]
list-lay/offset: to-pair reduce [self/offset/x self/offset/y +
self/size/y]
]
show-popup/window list-lay self/parent-face
do-my-events/away list-lay
do-face self self/data
]
reset: does [list-lay: none]
resize: does [
reset ; so list-pane will redraw at correct size
{Reset if a change has been made to the data}
size/x: max 32 size/x
size/y: max 24 size/y
either show-arrow? [

pane/offset: 0x0 pane/offset/x: self/size/x - arrow-button/size/x - 4

]
pane: none

]
]
It appears that this widget doesn't operate in the new version of Rebol/view
like it did with the previous version because the do-events function is not
the same.
In the previous version of Rebol/View, the do-events function was :
do-events: func [
"Process all View events."
/only "Restrict events to only a single window face" face
/away "Same as only, but event outside cancels" wf
/ports port-block [block!] "Port/action dispatch list"
/local flag event no-btn
][
if away [only: true face: wf]
wf: either all [only face/parent-face] [face/parent-face/pane]
[system/view/screen-face/pane]
if not flag: event-port [event-port: open [scheme: 'event]]
ports: reduce [event-port]
either port-block [
foreach [port job] port-block: reduce port-block [
if any [number? port time? port] [if none? timeblk [timeblk: :job]]
append ports port
]
] [port-block: copy []]
insert/only port-block either only [
if block? get in face 'pane [
no-btn: foreach item face/pane [if get in item 'action [break/return
false] true]
]
[
event: first event-port
either any [
event/face = face
within? event/offset win-offset? face face/size
] [
if any [all [event/type = 'up no-btn] event/type = 'close] [hide-popup
break]
do event
] [
if away [
if not find [move time] event/type [hide-popup]
do event
]
]
]
] [[do first event-port]]
insert/only port-block event-port
while either only [[find wf face]] [[not empty? wf]] [
either awake: wait/all ports [
foreach item awake [
set/any 'result do select port-block item item
if all [value? 'result 'break = :result] [break]
]
if all [value? 'result 'break = :result] [break]
] [do :timeblk]
]
if not flag [close event-port event-port: none]
]
And now the do-events function source is :
do-events: func [
"Process all View events."
][
wait []
]
Can anyone expain me how to do now ?
Thank you
