Boost performance of Widget creation by using DocumentFragment, Range.createContextualFragment or something else?
Hi folks, I work with an app that builds hundreds of widgets and obviously has a performance hit. I'm well aware of performance improvements of the sort of: reduce the number of widgets, use directly html, use cell widgets, etc, however those paths are not helpful for me. I'm just interested in making widget creation even faster. There's well known techniques using DocumentFragment or Range.createContextualFragment: https://developer.mozilla.org/en/docs/Web/API/DocumentFragment https://developer.mozilla.org/en-US/docs/Web/API/range.createContextualFragment http://ejohn.org/blog/dom-documentfragments/ I noticed that in the GWT code and noticed that whenever creating widgets using UiBinder, GWT creates a hidden div that is directly attached to the DOM: https://gwt.googlesource.com/gwt/+/master/user/src/com/google/gwt/uibinder/client/UiBinderUtil.java (line 84) So apparently operations are not on an unattached DOM element which theoretically makes thing slower. I tried to attach it to a DocumentFragment instead and while it seems that I'm seeing a small performance improvement, it's still hard to prove as the numbers that I get still vary a lot. Anyway, my question for you guys is that if you know of attempts to improve the speed of widget creation and what approaches have been taken?

Re: SuperDevMode
Thanks so much for helping out! I got things up and running, your explanations and the video were really clear, thanks!

At that point, you don't need to have the SuperDevMode page open in the browser. Now you need to load the page the GWT app is hosted within.. I can often just go to my GWT project's war file and double-click the html file to load it into chrome, then choose the Dev Mode On bookmark to compile and run. If your page needs to talk to a server, then you'll want to launch from the server address (like the hosted Jetty in the video). In either case, once you have the SuperDevMode code server running, you then want to load your GWT host page then do the Dev Mode On compile.

Re: Firefox in OS X freezes in DevMode.
Thanks Colin, yeah that's what I figured, initially I thought that it would be a problem in the plugin given that it was only blocking Firefox and only in OS X (given that Chrome worked and also Firefox but under Linux). I started debugging and got all the way there. I doubt that it's a breakpoint or having to wait for a long time as I did leave the browser for a few minutes, there's no breakpoints and CPU is not peaking, so I'd think there's something else waiting. I'll follow your suggestion and check now the other side, but it's good to know that you haven't had an issue with FF and Mavericks as then that would sadly imply that there's something wrong with my computer :(.

Re: Firefox in OS X freezes in DevMode.
I really appreciate your help Colin. At this point I believe it's some misconfiguration in my computer. I tried to do a jconsole on the devmode process and it said it couldn't connect to it. I then did a jstack and said the same but this time the utility suggested to use a -F to force it, when I did that, I was able to see the threads. I then tried to launch firefox and sudo mode, and voila, that worked! So I open Firefox in normal mode, it can't connect to the plugin, I then try it in root mode and works... The devmode process and eclipse are running with my account, so I can't tell what else I could have messed up but the important is that I can work and move on. I appreciate the help, On Saturday, November 9, 2013 3:10:58 PM UTC-5, Colin Alworth wrote: If you can repro this on at least one other machine and get the details of what the JVM is doing, that'd be helpful. I have a very basic familiarity with the dev mode code from researching the FF dev mode memory leak, and would be happy to take a closer look. From your description it sounds like the JVM is either also waiting for the browser (and we'll need to figure out how it got into that bad state with one having ignored a message from the other), or the JVM is blocked on something else entirely, the real source of the bug. My bet is on the latter, that something funny is going on there. Recent updates to Dev Mode were made for all platforms, nothing mac-specific, so that seems unlikely. Getting an old copy of firefox and an old (pre-ff25) copy of the plugin would probably be worth testing as well if you are able to repro this on more than one box. Note: the FF-devmode memory leak has to do with the old pages failing to shut down the plugin correctly, so make certain that you don't load more than once. If you do, your JVM will have two different threads trying to talk to the browser, and it may be difficult to tell which one is the current one, versus the 'memory leak' one.

Hello,
I'm using GWT for 2 years now and i did many great things with it.
However, i'm still looking for how to implements KeyboardHandlers on
the BodyElement.
The only way i found is writing something like this in the HTML file :
bodyonkeypress=return keyPress(event); onkeydown=returnkeyDown(event);
onkeyup=return keyUp(event);
And something like that in the EntryPoint
public void onModuleLoad() {
// publish();}
private native final void publish() /*-{
$wnd[keyPress] = function(event) {
@webapp.client.Application::keyPress(Lcom/google/gwt/dom/client/
NativeEvent;)(event);
}
$wnd[keyUp] = function(event) {
@webapp.client.Application::keyUp(Lcom/google/gwt/dom/client/
NativeEvent;)(event);
}
$wnd[keyDown] = function(event) {
@webapp.client.Application::keyDown(Lcom/google/gwt/dom/client/
NativeEvent;)(event);
}
}-*/;
But i'm really not satisfied with that solution.
Any ideas please ?

ui:image, image within an anchor or a button
I'd like to have an image within an anchor or a button tag. I'm using
the UiBinder and I need the anchor or button to be a widget so I can
use their HasClickHandlers interface.
I wanted to use an image widget so I can use an ImageResource,
something like this:
!DOCTYPE ui:UiBinder SYSTEM http://dl.google.com/gwt/DTD/xhtml.ent;
ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'
ui:with field='res' type='com.test.Test.Resources'/
g:HTMLPanel
g:Anchorg:Image resource={res.add} / Add/g:Anchor
/g:HTMLPanel
/ui:UiBinder
But since neither the Anchor nor the Button can take widgets, I get
the Found widget in an HTML context error.
I've seen posts mentioning the ui:image tag but couldn't find
documentation on how to use it and I couldn't get it to work.
If I do:
!DOCTYPE ui:UiBinder SYSTEM http://dl.google.com/gwt/DTD/xhtml.ent;
ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'
g:HTMLPanel
ui:image src=add.gif /
/g:HTMLPanel
/ui:UiBinder
It's doing something since it won't compile if add.gif is not under
the right package. However when I see it in the browser, the ui:image
didn't get compiled into an image.
Do you know what am I missing here?
Thanks!

Re: Is there a way to mock JSONObject?
Not as good or ideal as a mockobject but you could use the GWTTestCase. On Feb 2, 4:19 pm, Kevin Q kevin.jing@gmail.com wrote: Our application consumes JSON web services. We're using JSONParser, returning a JSONObject, and construct domain models from the result JSONObject.

JSONObject is an interface, so EasyMock can't help here. (correct me if I'm wrong) Also, I tried creating a class MockJSONObject extending JSONObject, and replace the put/get logic with HashMap based implementation but still no avail, because the JSONObject constructor calls native JS code as well...

UiBinder and non standard CSS properties.
Hi,
UiBinder can't seem to take non standard CSS properties.
I have the following:
ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'
ui:style
.test {
-moz-border-radius: 4px;
}
/ui:style
g:HTMLPanel
input type=text class={style.test} /
/g:HTMLPanel
/ui:UiBinder
And it shows the following warning when trying to display the page:
21:01:53.994 [WARN] [gwtsandbox] Line 3 column 20: encountered -.
Was expecting one of: } ; IDENT
Is this as designed that you can't use non standard CSS properties?
Thanks,

Re: Blank Screen in IE8 but Normal in FF3.5
I have the same problem and also for me the x-ua-compatible tag
fixed it.
I created a project using the gwt eclipse plugin, here's the java
file:
===
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.GWT;
import com.google.gwt.uibinder.client.UiBinder;
import com.google.gwt.user.client.ui.LayoutPanel;
import com.google.gwt.user.client.ui.RootLayoutPanel;
public class GwtSandbox implements EntryPoint {
interface Binder extends UiBinderLayoutPanel, GwtSandbox { }
private static final Binder binder = GWT.create(Binder.class);
public void onModuleLoad() {
LayoutPanel panel = binder.createAndBindUi(this);
RootLayoutPanel.get().add(panel);
}
}
===
Here's the ui xml file:
ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'
g:LayoutPanel
g:layer
g:LabelLorem ipsum.../g:Label
/g:layer
g:layer left='25%' right='25%' top='4px' height='10em'
g:LabelHeader/g:Label
/g:layer
/g:LayoutPanel
/ui:UiBinder
I can see it working in Chrome and in FF, however in IE8 I don't see
anything, if I inspect it using the DeveloperTool I see that the
markup is there but is not displayed. If I add the x-ua-compatible
tag to the html where the gwt script (nocache.js) is included, then it
works in IE8.

However, I have tested a simple DockLayoutPanel including a map (which
I thought could be the problem) and it all seems to work fine in IE8
standards mode - so there must be some other factor in my code that
prevents the DockLayoutPanel from displaying. I am happy for now with
the meta tag but will try to figure out what the cause is some time.

Validating ClientBundles ?
Hi, After upgrading the Eclipse plugin to GWT 2.0, whenever I import my Eclipse projects, Eclipse crashes. After importing the projects, I see multiple multiple (~12) jobs spawned called Validating ClientBundles, then it either shows a warning saying that it ran out of memory or just closes. When inspecting the Eclipse log, I found this: !ENTRY org.eclipse.core.jobs 4 2 2009-12-22 11:07:17.178 !MESSAGE An internal error occurred during: Refreshing workspace. !STACK 0 java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:597) at org.eclipse.core.internal.jobs.WorkerPool.jobQueued (WorkerPool.java:145) at org.eclipse.core.internal.jobs.JobManager.schedule(JobManager.java: 1001) at org.eclipse.core.internal.jobs.InternalJob.schedule (InternalJob.java:391) at org.eclipse.core.runtime.jobs.Job.schedule(Job.java:435) at com.google.gdt.eclipse.core.BuilderUtilities.revalidateCompilationUnits (BuilderUtilities.java:170) at com.google.gwt.eclipse.core.clientbundle.ClientBundleResourceChangeListener $1.visit(ClientBundleResourceChangeListener.java:154) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:68) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:79) at org.eclipse.core.internal.events.ResourceDelta.accept (ResourceDelta.java:48) at com.google.gwt.eclipse.core.clientbundle.ClientBundleResourceChangeListener.visitResourceDelta (ClientBundleResourceChangeListener.java:124) at com.google.gwt.eclipse.core.clientbundle.ClientBundleResourceChangeListener.resourceChanged (ClientBundleResourceChangeListener.java:116) at org.eclipse.core.internal.events.NotificationManager$2.run (NotificationManager.java:291) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.NotificationManager.notify (NotificationManager.java:285) at org.eclipse.core.internal.events.NotificationManager.broadcastChanges (NotificationManager.java:149) at org.eclipse.core.internal.resources.Workspace.broadcastPostChange (Workspace.java:313) at org.eclipse.core.internal.resources.Workspace.endOperation (Workspace.java:1022) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run (InternalWorkspaceJob.java:45) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) === These are my JVM settings in eclipse.ini: --launcher.XXMaxPermSize 256m -Xms256m -Xmx1024m -Xss1024k Is there a way to turn off this validation upon importing the project.
