Passing data between windows, is usually a mute point, as usually you
wouldn't associate the data with the window, but with an class instance.
The usual method I go about in setting up data storage, is to create a
class, be it specific, or just a simple Struct class, that will store the
data that I want referenced throughout the app, then create an instance
stored as a constant, which would make it available no matter what class
your dealing with. An example of this would be:
# ProgInfo.rb
require 'struct'
ProgInfo = Struct.new(:info_a, :info_b, :info_c)
GlobalProgInfo = ProgInfo.new
# WindowControllerA.rb
class MyWindowControllerA
def some_event()
GlobalProgInfo[:info_a] = "This is a dummy string"
GlobalProgInfo[:info_b] = 32
GlobalProgInfo[:info_c] = "Yet another dummy string"
-- Open Window code to open up your next xib instance.
do_window_b_open()
self.close()
end
end
# WindowControllerB.rb
class MyWindowControllerB
def some_other_event()
some_text_edit.setStringValue(GlobalProgInfo[:info_a])
end
end
This of course is some mock code, but it gives you the general idea of what
you should follow, to make it work. And I am sure, this is but one of many
different ways in which you can pass data between instances.
hth,
Mario
