Message sent when object placed onto card

Hello,
Is a message sent to the card when an object is placed on the card? Like when a new field or button is added? I need to grab the object ID of the newly added object.
Thanks
M

NO, no message is sent.
BUT, if you do this:
you will get what you need.

The message(s):
newcard
newbutton
newfield
etc.
is/are sent to the newly created object, so you could "catch" that in your card script.

You guys are a great tag team
on newWidget
put the id of the last control into NewWidgetID
end newWidget
should be just the fix I was looking for!!
Thank you!

There are at least a dozen "new..." messages sent whenever anything, er, new is created. They are invaluable. Look up "new" in the dictionary for a complete list.

Hi Klaus, is it possible to do this "catch" thing in pointer mode? If so, script in card or somewhere else?
Thanks

Hi Craig, I am presuming (based on some experiments) that these messages are not sent up the message path to the card in pointer mode? Which leads to a broader question, are any messages sent in pointer mode? (and to clarify, I am referring to drag/drop actions from the tools palette).
Cheers,
Mark

Hi Mark,
just made a test:
Created a new stack with an opaque graphic, because a "naked" card does not accept any DRAG_XXX message.
Added this script:
Code: Select all
on dragEnter
set the dragaction to "copy"
end dragEnter
on newbutton
put the seconds
end newbutton
Then I used the message box in POINTER mode :
Code: Select all
create button in cd 1 of stack "test"
and got the seconds.
Then I dragged a file onto the card, still in POINTER mode and saw the PLUS cursor.
I think the LC tools palette also works with DRAG_XXX messages.
Hope that will answer your questions.
Best
Klaus
P.S.
Not sure, but maybe the IDE will catch the "new_xxxx" messages if you drag'n'drop
an object from the tools palette?

I did, AND there seems to be no
newControl or
newObject,
or, for the sake of argument just
new by itself.
THIS, in the cardScript does nothing:
Code: Select all
on newButton
put the name of the last control && the id of the last control
end newButton

Your script in my card shows this correctly in the msg:
button id 1003 1003

Richmond.
Posting a tiny stack example is right up your alley.
