Comet

Am I correct in my understanding that Comet only works when something changes serverside? Say, one client increments a counter (as per the example), then the server pushes the new value to all connected clients.

Is there a way that Comet can be set up to push information every so often? This way being independent from any user input.

If you want to do periodic updates, I would recommend having the
clients poll, rather than using Coment.

Comet is good for the case where you have events occurring at
unpredictable times and you need to push notification of them out to
all clients. In this case polling, is inefficient because you're
either wasting resources by checking for events when there aren't any,
or introducing latency when there is a new event but you're waiting
for the next poll. There's a trade-off between efficiency and latency
- the more frequently you poll the more resources you waste, but the
less frequently you poll, the more latency you introduce. Comet solves
this by using fewer HTTP requests, and sending events as they occur.

If I understand your situation correctly, you want to update clients
on a regular schedule. It's not a counter so much as a clock that's
being updated. In this case, polling is quite efficient. You know when
there will be new data, so you just have to schedule the clients to
poll at those times - high efficiency and low latency.

Sure. For example you can control any client connected to the
CTCounter application with something along the following lines from a
workspace:

CTCounter model count: 321.
CTCounter pusher javascript: [ :script |
script << (script jQuery: #count)
text: CTCounter model count ].

jQuery tabs

In reply to this post by Robert Sirois

I'm goin' all out with questions today I guess heh. The following is the functional test for the jQuery tabs. On the second to last line there is a method called #fullURL. I browsed it, but frankly I have no idea what it does. The anchors set up in tabs do not render anything in the tab without that method being called. What does it do and how does it work? Just out of curiosity.

renderContentOn: html
   html div
       script: html jQuery new tabs;
       with: [
           html unorderedList: [
               self berries keysAndValuesDo: [ :name :description |
                   html listItem: [
                       html anchor
                           url: (html jQuery ajax
                               html: [ :h | h text: description ];
                               fullUrl);
                           with: name ] ] ] ]

That's how the jQueryUI tabs work. If you want to load the contents of
the tabs lazily jQueryUI expects exactly this kind of HTML template
where the load actions are anchors within an unordered list. See the
jQueryUI documentation for details:
<http://jqueryui.com/demos/tabs/#Ajax_mode>.

Is there an addon for something like Prototype's periodic updater? I noticed there are a few out there, but is there a Seaside wrapper for them?

You can tell any Javascript object

aJavascriptObject interval: 1 second

to execute it every second.

RE: [ANN] JQWidgetBox now with font effect, week calendar and sheet

Oh... heh. That was gonna be my next question. I was trying to use the prototype periodic updater to change something that Comet responds to.

I added your #interval: method to an ajax callback and it seems to work just fine that way (only using CT/JQ). The other thing I was trying to do was make a separate Comet page that just... does the comet thing. This way someone could connect to a page that updates something while other peeps could connect to a page that just sees the changes.

I'll certainly try out any tips tonight :)

Server Events

Is there a way to set up a periodic event on the Seaside server independent of any clients? (I guess a Kom server, in this case.)

jQuery widget >> destroy

In reply to this post by Lukas Renggli

A dialog is a widget so I should be able to call 'destroy' on it, right?

script: (html jQuery new dialog onClose: html jQuery this destroy);

or something like that.

Object References (Smaltalk)

In reply to this post by Lukas Renggli

Is there a way to get a reference to a calling object from the object that is being called?

For example in WACounter if you wanted a reference to whatever was calling #increase you could use something like #'self caller' to do that?

No, unless you expect periodic requests. Seaside only gains control if
somebody requests something.

It is however easy in Smalltalk to have a background thread do
something from time to time:

[ [ (Delay forDuration: 1 minute) wait. "do something" ] repeat ] fork

There is also a package that allows you to schedule events in more
sophisticated ways, but I forgot how it is called.

"thisContext sender" gives you the calling stack frame, but I doubt
that this is any useful in application code.

If you want to reset the DOM to its state before the dialog, then yes.

why not just pass it as an extra argument?

counter increaseRequestFrom: something.

WACounter>>increaseRequestFrom: something

something doSomething orDoNothing.
self increase.
