I hadn't thought about implementing this, but it seems it might be
useful. It may be that it would require some serious hacking in some
of the backends (if they don't support this sort of thing)...
Anyway, if we do implement it, I think perhaps using the "enabled"
attribute of the given window might be a natural way of doing it. I.e.
new_win = Window(title='dialogish window thingy')
old_win.enabled = 0
app.add(new_win)
And then set old_win.enabled = 1 in the code dealing with the new
window. (Of course some utility class or something could be created to
deal with the normal case of "modal windows" here, perhaps.)
I can't guarantee that this will be done in release 0.2, though (and
maybe not even 0.3) since I haven't looked into how hard it would be
to implement in the various backends.
What you could do while working with 0.1 (which doesn't have anything
like this) is to create some central mechanism for all your event
handlers (i.e. an instance with lots of event-handling methods). This
mechanism could then be told which windows were allowed to perform
actions and which weren't -- or something. (Not ideal, certainly...)
Anyway, I'll add this to the TODO list :)
