Re: Emulating CompletableFuture with Promise

2016-09-05 Thread Ian Preston

Thanks, Andrei. That looks great! Is there a reason you've changed the 
signatures on some of the CompletableFuture methods?

E.g. in the JRE,
public  CompletableFuture thenApply(Function 
fn)

has become

public  CompletionStage thenApply(Function fn)

[gwt-contrib] Missing JsInterop 1.0.0-SNAPSHOT

2016-09-05 Thread Colin Alworth

Looks like somehow the JsInterop jars are missing from the google-snapshots 
repo now, making it difficult to use the latest nightlies.

http://build.gwtproject.org/job/gwt/615/console shows creating, signing,

But the jars can't be found in maven

and the latest bom depends on 
it

  com.google.jsinterop
  jsinterop
  1.0.0-SNAPSHOT
  pom
  import




Oddly enough, there is a 1.0.0.j7-SNAPSHOT, apparently generated and 
deployed from http://build.gwtproject.org/job/gwt-java7/, but unless you 
happen to use GWT 2.8.0.j7-SNAPSHOT, this isn't terribly useful.

Any ideas how this might have disappeared (as well as all old versions), 
despite apparently being deployed fresh about 12 hrs ago?

[gwt-contrib] Re: ScriptInjector seems to be broken (2.8-SNAPSHOT)

2016-09-05 Thread Jens

Hm wondering how it ever worked for you as JsInterop usually qualifies JS 
code with $wnd but your D3.js has been injected into the GWT iframe. So 
AFAICT with JsInterop you would had to use TOP_WINDOW anyways. You can make 
it work within the GWT iframe but then you can't use JsPackage.GLOBAL but 
use a namespace that points to the iframe content window.

Also 
see: https://groups.google.com/d/msg/google-web-toolkit/GcsWUuzexvE/ApUg3sLZCQAJ

So it looks like this behavior has changed? But yes you would need to use 
"window" now to references the iframe's content window if you inject the 
code into the iframe.

It looks like this might be a side-effect of 
https://github.com/gwtproject/gwt/commit/c511029eaae4ec66ff874d7e69efd9516ccc78db
 

I am using JsInterop to interact with the D3 library, Using 
namespace=JsPackage.GLOBAL. I guess I will have to use "window" instead ?

[gwt-contrib] ScriptInjector seems to be broken (2.8-SNAPSHOT)

2016-09-05 Thread stuckagain

It looks like the ScriptInjector is no longer working properly in the 
snapshot.

I had code like this: 

ScriptInjector.*fromString*(pBundle.d3JS().getText()).inject();

To load D3 using a TextResource.


Since today (just came back after 2 weeks of holidays) the D3 object is no 
longer available in $wnd.


I changed the code to this:

ScriptInjector.*fromString*(pBundle
.d3JS().getText()).setWindow(ScriptInjector.*TOP_WINDOW*).inject();


and then it works.

This is the side-effect of a bugfix:

GWT2.8RC : onResize() calls changed

2016-09-05 Thread 'Thomas Lacroix' via GWT Users


Hello,
I have a class that implements ResizeComposite and overrides onResize().
A change I see migrating from 2.7 to 2.8RC2 is that the onResize() method 
is called much more frequently (i.e. when the widget is shown from a 
tabPanel) whereas this method used to be called only (mostly?) when I 
resized the window manually with 2.7.
I am not sure if this is a bug (hidden state may be considered to have a 
null size ?) but it is a change of behavior to take into account.
Thomas
PS : Thx for 2.8!

Re: Emulating CompletableFuture with Promise

2016-09-05 Thread Andrei Korzhevskii

I guess you need to super-source this class so the gwt compiler could use 
it.

You can take a look at my initial CompletableFuture implementation here:

https://github.com/nordligulv/gwt/tree/completable-future
https://github.com/nordligulv/gwt/commit/ea70c5358bac3c939cb0c1628a58ccc462cd7423

Feel free to use it but note that I haven't tested it properly yet.
