Scripting Cut/Copy/Paste in custom menus

[Kay C Lan]

Your suggestion, if it didn't break many stacks, would certainly slow them down.

I mainly work with a Stack, a single card with anywhere between 10s to
over a 100 fields, and a database. Going Next or Previous record
populates those fields by using 'put' statements. Currently, even with
100+ fields it all happens in a blink of the eye. The user is then
left to check the data, and if any are wrong those individual fields
are changed, the closeField message is sent, which normally goes
through some convoluted data verification process which includes not
only checking the format of the data but also checking the MAX, MIN
and UNIQUE entries in the database. Once all that is done the record
is updated and everything is sweet.

With what you are suggesting, every time I go Previous or Next the
closeField message would be triggered 100+ times which is just a
complete waste of time. The current logic of not triggering a
closeField message has been with us since the birth of HyperCard.

Frankly I wouldn't be surprised if you don't already have 1000s of
situations across all your own stacks that already rely on this
behaviour; the initial opening of your stack with all the fields
prepopulated with data immediately comes to mind.

>From memory I handled your situation by setting a custom property in
each field if data was pasted into it and then 'on exitField' testing
to see if data had been pasted in:

In the Edit Menu Script something like this:

   ...
    case "Copy"
         set the clipboardData["Text"] to the selectedText of the focusedObject
         break
      case "Paste"
         put clipboardData["text"] into the focusedObject
         set the cFldModByPaste of the focusedObject  to true
         break
     ...

and then in every fld script * something like this:

on closeField
   --do what you need to here
end closeField

on exitField
   if (the cFldModByPaste of me = true) then
      --content change by paste so do closefield
      set the cFldModByPaste of me to false
      send closeField to me
   else
      --content hasn't been pasted in or changed
   end if
end exitField

* if groups of flds do exactly the same thing then you can save time
by placing these scripts in a button and using behaviors.

This has the net effect of *disabling* cut/copy/paste/clear. I can live with that, because I have scripted the necessary menus to mimic the behaviors of those actions, but I am finding some quirks.

I assumed this was because the field was not getting selectionChanged, so I sent selectionChanged to the focusedObject after the cut/copy operations. Still, closeField does not get sent when I tab out of it. closeField DOES get sent if I simply edit the field then tab out.
