Reopen the stack

[liveCode]

How can I make the pile closed? He will ask "Do you want to close?" And if not then he will return the pile?

[richmond62]

One or 2 odd things here:

1. What do you mean by a 'pile'?

2. Isn't 'livecode' an odd user name?

Anyway, as far as I can understand from your posting let's imagine a button:

and let's give it some code:

Code: Select all

on mouseUp
   answer "Do you want to quit?" with "Yes" and "No"
   if it is "Yes" then
      quit
   end if
end mouseUp

[liveCode]

I need it that if the answer is no, then LiveCode will go back to the stack
That is, when I close the app

[richmond62]

Try my sample stack and see what happens when you select "No".

[liveCode]

Nothing happens but I need when exiting the app then it will go back in about such a code:
on closeStack
answer "exit?" with "no" and "yes"
if it is "no"
then
// Return to the app
end if
end closeStack

[richmond62]

That looks very odd to me, I suggest you try to work out how to do that by yourself.

[liveCode]

What's odd?

[richmond62]

If there is nothing odd about it you shouldn't have to ask the question.

Hi livecode,

welcome to the forum!

To learn more about the basics of Livecode, I recommend these stacks:
http://www.hyperactivesw.com/revscriptc ... ences.html

If the user wants to close a window via the button in the title bar, the -> closestackrequest
message is sent to LC. So just put this into the stackscript:

Code: Select all

on closestackrequest
   answer "Really close the stack?" with "no" and "yes"
   if it = "yes" then
     # we let the message pass, so LC will close the stack:
    pass closestackrequest
  end if
  ## No need to take action if user clicks "no", understand why?
end closestackrequest

Best

I want this to happen when someone closes the app on the phone and then it asks if to exit or not

[liveCode]

When the user closes the app on the phone then even if he clicks "No"
Then it will close because the phone closes the app

[Klaus]

I am afraid we cannot do this on the mobile platform!
Because the user can use the hardware button on the phone and we cannot "trap" this.

[liveCode]

It can be detected by on closeStack Was I wrong?

[Klaus]

No, but this does not work as expected on mobile, as you already experienced:

When the user closes the app on the phone then even if he clicks "No"
Then it will close because the phone closes the app

The closeStack message is sent when the app is quitting. It allows you to do some things before it shuts down. For example, you can use that message to save user preferences to a file, or to reset controls on the card. But the message does not allow you to stop the shutdown because it is already happening.

If you have a Quit button you can control the shutdown by using Klaus' handler. But as he said, you can't control the hardware phone button behavior.
