Re: How to show a load screen during rpc call?
Hi, what I'd to is:
1.) Display an image with some loading... animation
2.) Start the RPC asynchronously, e.g. like
tagDatabaseService.loadAllTagsForPerson(new TagQueryMessage(
tagQuery), new
AsyncCallbackTagListMessage() {
public void onSuccess(TagListMessage
result) {
// HERE
3.) at the spot marked with //HERE, remove the image again and do
something with the result you obtained via RPC
Hope this helps...

Hi,
I need to load a few things from my server after a user gives input.
Can somebody give an example how I can show a load screen as long as
the rpc is not finished? I structured the app in mvp style ... any
example would help me
Best regards
Thanks

Have a look at the following loading panel: http://www.sencha.com/examples/explorer.html - you can find the explorer src and the loading image here: http://www.sencha.com/products/gwt/download.php -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to show a load screen during rpc call?
This doesn't answer your question directly but it should give you some
ideas:
public abstract class ActionCallbackResultType implements
AsyncCallbackResultType {
@Override
public final void onFailure(Throwable caught) {
BusyIcon.hide();
Window.alert(RPC Error: + caught.getMessage());
handleFailure(caught);
}
@Override
public final void onSuccess(ResultType result) {
BusyIcon.hide();
handleSuccess(result);
}
/* Override to handle event failure result */
protected abstract void handleFailure(Throwable caught);
/* Override to handle event success result */
protected abstract void handleSuccess(ResultType result);
}

Re: How to show a load screen during rpc call?
OK, I have not used RpcRequestBuilder yet and only used RequestBuilder to alter the target of the request. How exactly would you use RpcRequestBuilder to hide the panel? And also from what I understood RpcRequestBuilder has nothing to do with actually sending the request so displaying a panel on creation of the request is kind of a short moment too early. I think I'd stick to a combination of a subclass of RequestBuilder where in send() the panel is shown and an implicitly assigned custom abstract AsyncCallBack implementation where onSuccess()/onFailure methods hide the panel and delegate the onSuccess()/onFailure() to a subclass. This of course depends on two things: 1) usage of return type in async service interface 2) possibility to use a subclass of RequestBuilder in async service interface (not sure about that but I might give it a try) Andreas On 3 Jul., 23:27, Thomas Broyer t.bro...@gmail.com wrote: On 3 juil, 21:45, andreas horst.andrea...@googlemail.com wrote: This sounds really great Thomas, haven't tried that yet.

How exactly would you use RpcRequestBuilder to hide the panel? And also from what I understood RpcRequestBuilder has nothing to do with actually sending the request so displaying a panel on creation of the request is kind of a short moment too early. Anyway, display will only be updated after your code is done processing the event and yield to the browser, so doing it before the new RequestBuilder or after the request.send() does change anything (provided you don't yield to the browser in between). I think I'd stick to a combination of a subclass of RequestBuilder where in send() the panel is shown and an implicitly assigned custom abstract AsyncCallBack implementation where onSuccess()/onFailure methods hide the panel and delegate the onSuccess()/onFailure() to a subclass. The advantage of RpcRequestBuilder#setCallback wrapping the RequestCallback passed in argument, rather than an abstract AsyncCallback, is that it doesn't change anything at the call site: your don't have to remember to use the MyAsyncCallback abstract class. Unless that's what you mean by implicitly assigned custom AsyncCallback. This of course depends on two things: 1) usage of return type in async service interface 2) possibility to use a subclass of RequestBuilder in async service interface (not sure about that but I might give it a try) You'd have to provide your own RpcRequestBuilder, overriding doCreate(), to use your own RequestBuilder subclass. Which means you can have void or Request method return type, because GWT-RPC will call send() itself on your subclass returned by doCreate. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

This sounds really great Thomas, haven't tried that yet. Can this be done by subclassing RequestBuilder?

Re: How to show a load screen during rpc call?
You could show your load screen (for example a popup panel or even just a label) right after issuing the RPC and hide it in onSuccess() and onFailure().
