Marking a Window for Closing

As described in The Skeleton, the "close" status of a Window is often used for loop control:

until window.should_close?
  # application logic
end

A Window is marked for closing either when a user "exes out" of it or when your application logic manually marks it. The window is not actually "closed" until it is destroyed.

should_close?

You can check whether or not a Window is currently marked for closing with the should_close? method:

window = Window.new
window.should_close? # => false

should_close? returns true if the Window is currently marked for closing, and returns false otherwise.

should_close? must be called from within a run block definition.

should_close and should_not_close

If you'd like to manually mark a Window for closing, you can do so with the should_close method:

window.should_close? # => false

# manually mark the window for closing.
window.should_close

window.should_close? # => true

Alternatively, you can explicitly mark a Window to not be closed with should_not_close:

window.should_close? # => true

# manually mark the window for not closing
window.should_not_close

window.should_close? # => false

should_close and should_not_close must be called from within a run block definition.
