Completely deleting substack / stack

[shawnblc]

I have a stack with a substack. On the substack I have a button and I want it to delete the substack. I believe I did this about 3 years ago. I guess I need to spend more time with LC What am I doing wrong?

Basically I want the substack to show only once during the lifetime of the application.

On the substack I have:

Code: Select all

on mouseUp
      answer "Hello"
      wait 5 milliseconds
      delete stack "testCard"
end mouseUp

On the main stack I have:

Code: Select all

on closeStack
      save stack "mainStack"
end closeStack

Hi Shawn,

I think LC does not like to delete a stack while a script IN that stack is being executed.
Just like you cannot delete controls with/in their own script(s).

Add a handler in the MAINSTACK thaqt will delete the substack:

Code: Select all

command el_deleto
  delete stack "testCard"
end el_deleto

Then just call this handler in the substack:

Code: Select all

on mouseUp
      answer "Hello"
      wait 5 milliseconds
      del_deleto
end mouseUp

That should do the trick.

Thanks Klaus, but I'm still having issues.

Hi Shawn,

you need to type a bit more careful:

Code: Select all

on elDeleto
   ## if there is a stack stack "testCard" then
   if there is a stack "testCard" then
      delete stack "testCard"
   end if
...

With this script I got it working:

Code: Select all

on mouseUp
   answer "hello"
   wait 5 milliseconds
   
   ## No script must be running when we remove the stack!
   close this stack
   
   ## we need to add a tiny dealy here, or the script is still considered running and we get an error
   send "elDeleto" to stack "Test" in 1
   
   ## If eldeleto does work, this line will throw an error, since the stack is not present anymore!
   ## close stack "testCard" of stack "Test"
end mouseUp

Excellent Klaus. Got it working. Thanks.

I need to try and spend an hour or so with LC every day instead of dropping off and not using it for years at a time. Every time I go back to LC and tinker, I'm amazed.
