MaterialSearch - issues

Hi Everyone -

The GWT Material Design is a great contribution. I'm trying to use it in our project (http://peruselab.com), we plan to release in Aug 2016.

One of the component I'm trying to use is the MaterialSearch. It's well designed and works as expected. However, the behavior of this is inconsistent across browsers. This may be a known issue but I'm sharing it here for the benefit of others. If anyone has found a work around please let me know. You may verify my findings at the demo site.

Works in

Opera Version 36.0 on Windows 10.x

Safari Version 9.1.x on Mac

Chrome Version 49.0.2623.112 on Mac but Version 50.x failed

Works but not as expected in -

Chrome Version 51.0.2704.29 beta-m (64-bit) on Windows 10.x

Chrome Version 50.0.x on Mac failed (Harrrr... why did I update?)

Haven't tried 32 bit version of Chrome yet

MS Edge Version 25.10... on Windows 10 (results list is shown even before start searching)

Firefox Version 24 (yes, I have this version to debug GWT apps in classic mode, occassionally) on Windows 10.x

Does not appear in (actually the search icon momentarily appears and disappears) --

Firefox Version 44.0.2 & 46 on Mac

Firefox Version 46 on Windows 10

Have a great rest of the weekend!

Thanks

Sam Velu

Data grid has multiple columns and each column has cell to display each row which is regular implementation.

Re: RAM memory continously increasing while using GWT Application in IE Browser

Thamarai Kannan:

Any reason you chose GWT 2.5.1 instead of the latest version? As Gilberto responded it would be easier to pinpoint the problem if you could share your code, unless you are restricted.

We are also using GWT 2.5.1, and we faced a memory leak under IE. I'm not sure whether it applies to you, but we did find the root cause of a leak for Cell Tables.

Announcing Ahomé Desk

We are so excited to share Ahomé Desk Beta 1

A year ago @Elom and I had a vision of creating a unique and personal cloud experience. An intelligent layer over the things you care the most.

The cloud is everywhere. And the number of services we use increases exponentially. Document, , Photos, Videos, Musik, Contacts, Friend, Events, Locations, Social Networks etc ...

We found ourselves using more and more applications every day. Keeping track on all this services becomes even more challenging.

And because most of those services are not designed to play nice with each other, as users we found ourselves switching back and fort between them. Loosing focus. Wasting time.

Ahomé Desk is our attempt fix this situation. Our attempt to intelligently organise the way we use the cloud.

A place where you access the things that are important to you in a simple familiar, beautiful interface. Organized and synchronized across devices.

A place where the user is at the center and not the services that she uses.

Your Home in the Cloud

Please keep in mind that this is a beta release. So expect bugs and things that or not polished and or finished yet.

We are just at the beginning of our journey, we have lots of things in the pipeline and cant wait to share with you what s coming next.

We need you to make this a great product.
Please visit link below and let us know what you think.

Re: What needs to be done after a successful login

One of the great things about "single page apps" if, not a security issue, you can let the user carry on where they left off... text box input, pending file uploads, tab position...

Re: execute perl from gwt

Hello,

it is not possible because gwt it's as babel/typescript - client side.

Everything what you can do - it's to send a request to server side, invoke perl script there and return result back to the client side.

error

Don't use it?

java.lang.Runtime isn't part of the emulated classes you can use in client-side code to be compiled by GWT: http://www.gwtproject.org/doc/latest/RefJreEmulation.html#Package_java_lang

error

how can i resolve these error

java.lang.Runtime can not be found in source packages. Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly.

execute perl from gwt

can anyone tell me how to execute perl script from gwt step by step process as I am just start working with gwt.

Re: Global Event bus for separate compilation modules

I understand the turducken model that but I not suggest the linked implementation because the gwt compiler in that way will produce redundant code in each module and this can cause some problems at runtime of js code. I suggest to use a global js object and reference it trough a native jsni method. Using window.post is a specific way to reuse a global JS object and obtain a messaging mechanism with a single call and without the problems I see in re-writing the bus as a gwt module. With gwt 2.8 this problem is solved with jsinterop.

Re: Global Event bus for separate compilation modules

I have just suggestion to use some JS eventbus, expose it as global JS object and get reference on that in both modules.

Global Event bus for separate compilation modules

No, I think Ahmad is talking about the "turducken" architecture. I just stumbled on http://gwtdaily.com/post/79849550460/gwt-interappeventbus which should answer the question (with link to the presentation about the original concept)

Global Event bus for separate compilation modules

What do you mean for separate modules? Gwt enables to develop separate modules but during compilation time you will get a unique javascript source... if you mean that you have more than one entry point I can imagine that you are running them in separate window or separate iframe. If so you can build an event driven interface trough Window.postMessage, when a window receives a message you can intercept it with window.addEventListener('message', listener). More info on https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage

Re: GWT, Firefox, and focusout

You might need to look into the DOMImpl and DOMImplStandard classes and dispatchEvent... It might be easier to add the event listener via JSNI as well.

jsinterop: casting between jstypes

Hi,

I just started experimenting with the new jsinterop and I have one question.

I am using bootstrap which is using jquery, Although there are implementations around (https://github.com/workingflows/gwt-jquery) I thought to give it a try as a learning exercise, to see how far I can get before I incorporate somebody else's solution.

So here is the core from jquery

@JsType(isNative = true)
public class JQuery {
@JsMethod(namespace = JsPackage.GLOBAL)
public static native JQuerySelection $(String selector);
}

where JQuerySelection is
@JsType(isNative = true)
public class JQuerySelection {

}

and it works! Great

Now let's try to bring bootstrap inside. I want to user their modals. The way to get a modal is through jquery. Let's extend the jqueryselection

JsType(isNative = true)
public class BootstrapModal extends JQuerySelection {
    public native void modal(String command);

    @JsOverlay
    public final void show() {
        modal("show");
    }

    @JsOverlay
    public final void hide() {
        modal("hide");
    }
}

//////////////////// java caller ----- It crashes on cast

((BootstrapModal) JQuery.$("#modal_id")).show();

Now when I try this from my java code it crashes (saying that mypackage name (com.mypackage.) is not a property)

What is the way to use jsinterop in order to capture the implicit parent/child relationship between BootstrapModal and JquerySelection?

I work around it by adding in BootstrapModal this

@JsMethod(namespace = JsPackage.GLOBAL, name="$")
public static native BootstrapModal getModal(String selector);

but it doesn't strike me as the correct way to do it.

Any hints?

Re: gwt-2.8.0-beta1 / isn't it about time for a beta2?

No, I believe it's about having at least a snapshot of guava-gwt that's usable with the GWT beta2 or RC (I was absent at the meeting so don't have more info)

So, it is pending Guava? Is the Guava referenced being used as a part of the build system?

GWT Steering Committee Meeting (4/13/2016)

Java8

Good progress in adding support.

Need more tests for Java8: Soliciting contributions from community.

GWT 2.8

Main criteria: Get new Guava working with GWT 2.8 before releasing 2.8.

Github issues

Being used regularly

Thomas is driving a plan to handle this better. Will wait for this to be finalized.

Refresh of beta

Check how much work is left to be done to get guava building before deciding on this.

If 2.8 RC1 doesn't look imminent, put out a new beta.
