I have a stack where I use grouped objects as “wells” from which users can drag a copy for their own use. I need to be able to refer to the owner of these grouped objects but it’s also important for the groups to have names. The copied group has the same name as the original, but this is good, because the name is meaningful. Anyway, every newly created group has its own distinctive ID, so there should be no problem, right? Actually, wrong. If I have a group called “mygroup”, say ID 1004, which I copy and paste to create a new instance of “mygroup”, say ID 1015, my attempts to find out the owner of the objects in the second group always returns the owner of the first group instead.
In more detail, the original group and its copy both have a popup menu. I have given the button to whom the “menuPick” message is sent a “whoCalled” custom property, so that it resizes the proper controls depending on which instance was the source of the menu choice. Here’s my menuPick handler:
on menuPick theChoice
put the whoCalled of me into caller
put theChoice into word 1 of fld id caller
if theChoice is "towardsxy" then set the width of fld id caller to 188
else set the width of fld id caller to 240
put the long id of the owner of fld id caller into owningGroup
repeat with i=1 to the number of controls of owningGroup
get the name of control i of owningGroup
if word 1 of it is "group"
then set the right of control i of owningGroup to ((the right of fld id caller) - 5)
if word 1 of it is "image"
then set the left of control i of owningGroup to ((the left of fld id caller) + 4)
end repeat
end menuPick
(BTW is there not an easier way to get at the elements of a group than this? I hoped there was, and I was just too dense to figure it out. If so, please let me know. Any style tips, I would also be grateful to get.)
Everything in the handler works just fine until the command put the long id of the owner of fld id caller into owningGroup
What the variable “owningGroup” ends up containing is “Group ID 1004…” (using the same example as above), not “Group ID 1015…”, even when whoCalled is (correctly) referenced as one of the controls in Group ID 1015.
What can I do about this?
Short term: forget "the owner" and use the long ID instead, dropping the part before " group ID ".
Long term: All object references returned by the engine MUST be in their universal ID-based form unless the user specifically requests a potentially ambiguous alternative (like "long name").
Therefore I would consider this a bug, and would gladly vote for it in Bugzilla.
