Button images

Hi all

This should be easy but I am struggling with this at the moment. I
have been following the discussion on graphics in buttons with
interest, however I am stuck at step one!

I have a stack "Display" and a sub-stack "GraphicsStore". I can set a
button id 1005 (in the "Display" stack) to a image id 1234 in the
substack via the properties palette, however I am having trouble
changing the image via a script.

I can remove the icon by;

set the icon of button id 1005 to image id 0

however

set the icon of button id 1005 to image id 1234
or
set the icon of button id 1005 to image id 1234 of substack "GraphicsStore"

is not doing a thing.

I would appreciate any clues as to the correct syntax for changing
the button icons.

Thanks

Greg

Greg,

One way to set the button icons programmatically is to run the "setUp" handler below. It presumes that each button which is to receive an image icon has been given the same name as the image in the substack. It will run through all the cards in the main stack and if it finds a button whose name corresponds to an image in the substack, it will assign the image id to the button. (All images are located on the one card in the substack. It is relatively quick and painless.

On setUp
Lock screen
repeat with i =1 to the number of cards
set the defaultstack to "myStack"
go to card i
repeat with j = 1 to the number of buttons
put the short name of button j into tButtonName
set the defaultstack to "mySubstack"
if there is an image tButtonName then put the id of image tButtonName into tImageID
set the defaultstack to "images"
set the icon of button j to tImageID
end repeat
end repeat
unlock screen
end setUp
