Auto save on close stack

[AlexAdams]

How can I have a stack save itself everytime it closes without a user dialog? Is there a preCloseStack message or something similar?

Thanks,

[Klaus]

Hi Alex,

omit the "pre" and you are done

Add these lines to your closestack handler, that will do the trick:

Code: Select all

on closestack
  save this stack
end closestack

Klaus,

I am prompted to save the stack before the closeStack message handler has a chance to do anything.

Any other ideas?

Hi Alex,

ah, yes, that is an ugly inconvenience of the IDE that you cannot switch off
But this will NOT happen in a standalone, if that is what you mean.

Thanks. I'll setup a machine to test that. Does it work the same if the person is using Revolution Player?

Hi Alex,

yes the Rev Player behaves like a standalone.

Hi,

I would recommend using closeStackRequest instead of closeStack. In the closeStackRequest handler, you still have the possibility to cancel the close "message". For example:

Code: Select all

on closeStackRequest
  -- you might remove the line below, the next line and the
  -- last line if you want to auto-save without asking the user
  answer "Really?" with "Yes" or "No"
  if it is "Yes" then
    save this stack
    if the result is empty then
      lock messages
      -- do any additional cleaning up here
      if the environment contains "dev" then
        close this stack
      else
        quit
      end if
    else
      beep
      answer "Could not save. Want to close anyway?" with "Yes" or "No"
      if it is "Yes" then
        lock messages
        -- do any additional cleaning up here
        if the environment contains "dev" then
          close this stack
        else
          quit
        end if
      end if
    end if
  end if
end closeStackRequest

You might want to replace the quit command with this handler. Just make sure to just it in case you don't use MySQL or if there are any other libraries and externals that need to be stopped before quitting.

If you open the stack as modeless inside the IDE, the IDE won't ask you whether to save it and the only messages would be those from the script above.

Best,

Mark
