Thanks a lot Jacque and Jim; far much clearer for me now ;-))

So, as I need to get the number of cards of a given background "Bg1" each time I create a new card from one which has this background on it, I replaced copy/paste card (that I was trying before) with clone this card.

Indeed, with copy/paste the number of cards in background Bg1 does not increase by 1, while with clone this card it does.

Best regards from Grenoble

So, if one copy/paste a card including a group whose backgroundBehavior is set to true, the new card is not a part of the cards of the background despite the fact that this background is actually on the card. More, if one clone such a card (resulting of copy/paste) then the new card is not a part of the cards of the background!!

Yes, because when you copy/paste or clone, you are making a copy of the entire card including the background group. The new group looks identical but is really independent. It is the same as copy/pasting any other control, you get a new one.

The way to see this is to check the ID of the backgrounds.
I was missing that; OK, with copy/past card the name of the background remains but the ID changes

To include the cards as having the same bg ID, use the Place command.
it works with clone card too

It is also useful to rename backgrounds so that you don't get confused about which one is which.
In my case, I need to keep the same name

Also note: you can have multiple backgrounds on a single card, each having its own ID.
OK

In the stack script you could do this discovery technique:
on opencard
 put the backgroundIDs of this stack & "=stk" into  message box
 put cr & the backgroundIDs of this card & "=cd" after  message box
 put cr & the number of groups of this card & "=gr" after  message box
 pass opencard -- in case another handler is waiting for this
end opencard
Ok, I tried that, very usefull to better understand (I added "put cr & the number of cds in bg "bg1"

Also note that 'group' and 'background' are synonymous if the background behavior of a group it true.

You can use the Place and Remove as often as you like, since the (backgrounds and groups) belong to the stack, not the card.


Hope this helps,
