Message sent when object placed onto card

[marksmithhfx]

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

NO, no message is sent.

BUT, if you do this:

Code: Select all

put the id of the last control

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?

Look up "new" in the dictionary for a complete list.

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

Works for me as well. How could it not?

[Klaus]

Yes, Richmond, how could it not?

Posting a tiny stack example is right up your alley.
