Re: GWT architecture MVP/EventBus (mentioned at Google I/O)
Hi, Everyone I start to work on my app which has requirement to have some kind of action buffer in the client side. All the actions will push to this buffer and make request to server every 2 or 3 seconds. Basically it is doing batching. So it should be a good use case to use command pattern to achieve this. My question is if I am not using RPC but RequestBuilder, what should I achieve this? And for batching, there are different ways: 1) I can communicate with the server every 5 actions, for example 2) or I can communicate with server every 2 seconds. Can I do both with the command pattern? Thanks!

I answered these questions here (http://groups.google.com/group/mvp4g/ browse_thread/thread/d8ee207598bf02fa) event type=displayMessage calledMethod=onDisplayMessage handlers=rootPresenter eventObjectClass=java.lang.String / Isn't displayMessage and onDisplayMessage redundant? I, for one, wouldn't mind simply: event type=displayMessage handlers=rootPresenter eventObjectClass=java.lang.String / and expect onDisplayMessage to be called automatically (ie. event click fires onClick()) Good idea, I created an issue to make the calledMethod optional. Other than that, +1! It sure got my attention. Thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: oophm on a mac
I have run oophm on mac in eclipse. I think I just followed the guideline in GWT wiki page. I have not tried command line yet. -Ben On Jul 31, 11:56 am, Tom Malone tomjmal...@gmail.com wrote: running from command line with ant tried it on a linux vm image and seemed to work, just seems to be a mac thing.

Re: GWT Incubator project
Joe, thanks for your experiences. From the demo in the incubator project now, it seems like the PagingScrollTable is really powerful. -Ben On Jul 30, 9:22 pm, Joe Cole profilercorporat...@gmail.com wrote: We have been using the ScrollTable in production for a over a year. Things we have had to implement on our own (not sure if this stuff is covered in the current drops): - sorting using comparators - tablemodel interface (supporting paging) - storing of current sorting indices to original row indices. - We built our own paging mechanism, but if doing it again would probably use the incubators - On window resize recalculate columns. It works really well though, no complaints here. On Jul 31, 12:09 pm, Ben benzhe...@gmail.com wrote: Is there anyone using GWT incubator project in production?

Re: Composite - disabling click events
Check out GWT implementation of CustomButton.
It seems that the goal can be achieved by overwrite onBrowserEvent
(Event event) method without using the method proposed above.
FYI

Ok,
I used just basic approach, if anyone is interested in enabling/
disabling click events on your
own composite here it is:
public class MyButton extends Composite implements HasClickHandlers,
ClickHandler {
private final HashSetClickHandler clickHandlers;
private boolean enabled;
public MyButton() {
clickHandlers = new HashSet();
addDomHandler(this, ClickEvent.getType());
...
initWidget(your_complex_widget);
}
public HandlerRegistration addClickHandler(ClickHandlerhandler) {
clickHandlers.add(handler);
// don't care about the return value, nobody should need it
// if necessary return some convenient class extending
HandlerRegistration
// or create some special method for removing the clickhandlerfrom
the clickHandlers list
return null;
}
public void onClick(ClickEventevent) {
if (enabled) {
for (ClickHandlerhandler: clickHandlers) {
handler.onClick(event);
}
}
}
public void setEnabled(boolean enabled) {
this.enabled = enabled;
}
}
Any suggestions for improvements are welcome.

Re: GWT architecture MVP/EventBus (mentioned at Google I/O)
So if for a TextBox I need to bind both FocusHandler and BlurHandler,
I need to have two interfaces and combine them?
How does that work?

Does anyone have a working MVP/Eventbus sample of something simple
like the PhoneEditor?
I don't think I'm doing it right. The code from the IO presentation
leaves out enough details so that I'm not sure what to do.
For instance, in my Presenter.class,
I have something like this:
public class Presenter {
...
private Display display;
interface Display {
HasClickHandlers getSaveButton();
HasClickHandlers getCancelButton();
HasClickHandlers getNumberField();
HasClickHandlers getLabelPicker();
}
void editPhone(Phone phone) {
this.phone = Phone.from(phone);
display.getNumberField().setValue(phone.getNumber());
display.getLabelPicker().setValue(phone.getLabel());
}
...}
Obviously, a HasClickHandlers object doesn't have a setValue method.
It doesn't feel like I should be casting to the widget here, since we
went through all the trouble of using the Display interface.
I started looking at Mvp4g, but it seems to go off on a tangent with a
code generation class to wire up presenters and views via
xml.http://code.google.com/p/mvp4g/
It's also intertwined with some mvc4g classes.
I just want something basic that works, so I can seed my project from
there. A minimalist, working command style RPC example would be nice
too.
Anyone? If you're in the DC area, I'll buy you a drink!
interface Display {
HasClickHandlers getSaveButton();
HasClickHandlers getCancelButton();
HasValueString getNumberField();
HasValueString getLabelPicker();
}
This will work for this example at least. If you want to bind events
AND set a value to those fields you'd need to combine the two
interfaces in a new one, or perhaps have two accessor methods.
