Hi Brett,
Here is a little VID style element you can use to perform a particular
action onload. This will fire up after the
screen shows. The 'action is whatever is in the [] just like normal vid
stuff.
gadget: stylize [
onload image [
size: 1x1
rate: 1
cue: none
feel: make feel [
engage: func [face action event][
if action = 'time [
do face/action
face/rate: 0
feel/engage: none
show face
]
]
]
]
]
main-face: layout [styles gadget
size 440x220
at 0x0 onload [output/text: read http://www.rebol.com show output]
at 20x20 output: area
Button "Close" [quit]
]
view main-face
It can also be used to display a message, before and after the action like
this.
main-face: layout [styles gadget
size 440x220
at 0x0 status: onload "Loading..." 120x24 [
output/text: read http://www.rebol.com show output
status/text: "Loaded" show status
]
at 20x20 output: area
Button "Close" [quit]
]
view main-face
Hope this helps..
Cheers,
Allen K
