That is still not as loosely-coupled as subscribe/unsubscribe to a
string ID.

Hi Kenny,
I think you underestimate the power of databinding - it is a different
animal compared with the message system --- which I use myself a lot
I am not talkinf about data binding, just plain events (there are too types,
one allowing to sent data along). Cheers, Fritz

T.
I don't see the fundamental difference between custom (data) events and
messages.
But if somebody has an example for something what can't be done with an event
and can be done with the message bus or some guideline when to use which this
would be useful.
Cheers,

Took a look at that. I see your point now.

Thanks for the input. I am going to take a look at using events.
It may not be an widget event that determines which widgets to
access/manipulate. It could be the content of data returned from the
server or the value of a user input that determines which widgets to
manipulate.

I am currently on vacation in the Swiss country side and have only limited
internet access and even less time (three little kids ...). I hope fls's
example gets you further. Search for addListener and fireEvent in the API
manual. You can also look at the framework code (use grep to search
Idunno how you do it with other frameworks, in qooxdoo it's very swing-ish,
but more flexible, javascript being dynamically typed and not requiring
statically declared and implemented interfaces. Whatever object needs to be
aware of changes/events in another object simply registers a listener f
Fritz,
Could you post a simple example. Don't think I understand how that would
work.
Thanks

You could add event handlers to your widgets an fire a custom event whenever
you want to update them. This way you don't have to keep track of them.

Hi, Brand new to qooxdoo but pretty impressed so far. I'm coming from
application programming with PerlTk and Wxperl. Looking at qooxdoo for a
cross platform migration of a wxperl app. The interface is fairly
complicated and various callbacks need to supply data to
widgets/elements and enable/disa
