Since you are taking snapshots of other cards and the "preopen" is for
the control, I'm not sure you need to wait for the control to load. I
think the issue is the ID of the icon.
I just tried the handler you posted and there's more wrong than just the
icon ID.
on preOpenControl
import snapshot from the rect of card "Example"
set the icon of me to it
end preOpenControl
It might be a typo, but the first line will error without the "rect"
keyword: import snapshot from rect (the rect of cd "example"). Also,
snapshots use the 0,0 point of the monitor (not the stack) for
coordinates when dealing with cards, so the rect of a card will result
in the snapshot containing the top left portion of whatever's on the
monitor at that position. You'll need to translate the coordinates from
global to local coords. You can either do that using the globalloc
function or you can just use the rect of the stack instead of the rect
of the card. The second method won't always work if you have a menubar
on a Mac (which makes the stack shorter than the card.)
After either an import or an export, the "it" variable is not given a
value, so it becomes the string literal "it". You can't set an icon to a
string literal, you need an ID number.
While you can take snapshots of objects that aren't open, you can't take
them of cards that aren't open. Cards are not objects. I was unable to
get a snapshot of another card unless I went there first. This did work:
on test
get the rect of this cd
put globalloc(item 1 to 2 of it) into tRect
put globalLoc(item 3 to 4 of it) into item 3 to 4 of tRect
go cd 2
import snapshot from rect tRect
go back
set the icon of me to the short id of last img of cd 2
end test
The "export snapshot" offers more options. You can export a snapshot to
a variable and then put that variable into an image object. However, I
was still unable to get a snapshot without going to the card. This works:
on test2
lock screen
go cd 2
export snapshot from cd 2 to tVar as JPEG
go back
unlock screen
create img "iconImg"
set the text of img "iconImg" to tVar
set the icon of me to the short id of img "iconImg"
end test2
