When does the finish event get called in shoes?

Question

Using Shoes, I would like to have a block executed upon window destruction. I thought I could use the finish event, but in the following piece of code, "Starting" is displayed, but "Finished" is never shown.

---

Shoes.app(:title => "Test") do

    flow do
        start do |obj|
            alert("Starting")
        end

        finish do |obj|
            alert("Finished")
        end

        button "Hello"
    end
end

Answer 1

After doing some more researching...

It appears that the finish event in Shoes is currently only used for downloads.

In addition, it appears there is no onclose event currently, but it has been discussed.

Apologies for answering my own question, but putting the knowledge out there for others.
