undo stack

Is there any documentation on the undo stack?

I am looking for information on how to trigger undo/redo for a transaction.

Hi,

You might be interested in the Manager class which is documented here.

Hi Chris,

thanks very much for the comments!

I just like to add that usually you won't need the manager object. The LayoutView#commit and LayoutView#transaction methods are usually sufficient:

# Begins the transaction (undo/redo support)
view.transaction("Description of your function")
begin

  # your code goes here and will be undo/redo-tracked

ensure
  # Always commit (also in case of an exception)
  view.commit
end
