Re: Iframe = multithreading ???
And one more thing, UI thread is only one for windowed / process application. So the clicks and generally Browser can be blocked when you will use time consuming operation on UI. If you will use e.g. setTimeout, no clicking etc, then it could work much better. Because this single UI thread must be "shared" by renderer of all frames / windows / documents visible to the user :-) On Thursday, September 14, 2017 at 2:26:30 PM UTC+2, Paul Porombka wrote: > > YES, totally agree.

Re: Iframe = multithreading ???
YES, totally agree. This is probably because Web Workers don't use any UI there. So they are probably better scheduled and "lighter", so works much better than forcing multithreading with IFrames :-) But the concept is pretty nice, don't you think :-) And to clarify. I was rather also considering a situation where I have a blank page in IFrame, without any UI elements, probably hidden frame, that will handle heavy operations, sent there from parent using postMessage. Because user interactions on UI can cause the behavior you observed. Then I would be closer to Web Workers. But definitely Web Workers are the right way in such situations. PS: Did you try your test using Web Workers for comparison?

Re: Iframe = multithreading ???
Hi Ben, I see the time when you've posted the message and see the answers here, so I codn;t stop to write something here. I will answer YES to your question, but it depends. Generally, IFrame under the same domain is using the same thread. I don't know how it was at the time You've been asking, but now if you use IFrame with different origin (domain/host) it will use its own context, own event loop, so also ot will be separate thread. Currently a Web Workers concept is using this behavior. The problem was always with communication between those two frames, so it was also solved by "Messages". You are able to post a message to different ORIGIN and addEventListener to "message" event to receive such messages, and voila! You have two way communication between threads :-) So if you create a code that can be executed separately in different IFrame, and exeute it in different ORIGIN, then YES you will get REAL multithreading, not single event loop, real muti-event-loop :-) On Thursday, September 3, 2009 at 12:51:09 AM UTC+2, ben fenster wrote: > > i was wondering that if by opening another module in an iframe tag the > code of that module runs in another thread ?? > more over is the limit of 2 open http request apply on 2 diffrent > modules running in diffrent iframes ?? -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

How to add a GWT module to a dynamically created Iframe
What's the best way to handle this scenario ? - Code wise have I would like to have 2 seperate GWT modules. Modules as defined in this page <http://www.gwtproject.org/doc/latest/DevGuideOrganizingProjects.html> - Download both modules in a single download, as a js file. - Run one of the modules in a dynamically created iframe. Detailed description: I have a GWT module called 'embed' which generates embed.nocache.js file. I have another GWT module called 'widget' which generates widget.nocache.js file. I add embed.nocache.js to my HTML page. This adds a link called 'widget' in the HTML page. On click of this link, an iframe (say, widget.html) opens. widget.html has a link to widget.nocache.js. This file gets downloaded, gets executed in the iframe and puts a horizontal panel into the iframe. Now I need to eliminate a seperate download of widget.nocache.js file. Say I inherit 'widget' module in embed, it gets compiled and downloaded together. How do I initialise the all the 'widget' related javascript in a dynamically created iframe ? Can creating a custom linker help ? Thanks. -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

Re: [gwt-contrib] Re: CSS Resources are not set in Panels in an iframe
As long as both $wnd and $doc exist in the frame where you plan on
creating/rendering widgets, it shouldn't matter how you create or find the
iframe. This should only mean that your frame must be created when that
line of bootstrap code executes, either because you created it there, or
because you found it.

When doing this, you're neutralizing event handling on the widgets, making
many of them unusable.
What you need to do is either:
- load a GWT app into the iframe and communicate with it to make it
build the UI you're expecting
- or only "inject" elements into the frame, not widgets.
But one has to wonder why you want to use an iframe to begin with…

As Grzegorz Nowak said, you need to inject your stylesheet into the iframe
first; it's as easy as creating a
[gwt-contrib] Re: CSS Resources are not set in Panels in an iframe
According to this
<https://github.com/gwtproject/gwt/blob/master/user/src/com/google/gwt/resources/client/CssResource.java#L311>
'ensureInjected'
uses StyleInjector.injectStylesheet(String) to inject the text of the style
into head of $doc. You would have to manually inject it (Use
CssResource.getText()) into your iframe's head to be able to use it.
Unfortunately StyleInjector does not permit to specify the document to
which the style should be injected in similar manner ScriptInjector does,
so you will have to implement it yourself based on both ScriptInjector and
StyleInjector. After successful injection you can assign styles to elements
from Css/Gss resources.

[gwt-contrib] Re: CSS Resources are not set in Panels in an iframe
Hi Thomas,
the reason why I want to use an iframe is the following. I want to create a
JavaScript widget which is integrated into another third party page. Have a
look at this: https://www.livechatinc.com/ They have a chat widget which
has the following structure:
// widget content
I guess they use the iframe such that the page containing the widget does
not change the css or html tree of the widget.
Do you see how such a technique can be used with GWT?

[gwt-contrib] CSS Resources are not set in Panels in an iframe
I want to insert GWT Widgets like FlowPanel, HTMLPanel inside and iframe
using GWT. I find out how to insert GWT Widgets and Panels programmatically
into GWT. Here is how I do it:
public interface Resources extends ClientBundle {
@Source({Css.DEFAULT_CSS})
Css css();
}
public interface Css extends CssResource {
String DEFAULT_CSS = "test/client/app/start/StartView.gss";
String outerBox();
String iframe();
String test();
}
@UiField(provided = true)
Resources resources;
@UiField(provided = true)
Messages messages;
@Inject
public StartView(final Binder binder, Resources resources, Messages messages)
{
this.resources = resources;
resources.css().ensureInjected();
this.messages = messages;
initWidget(binder.createAndBindUi(this));
final IFrameElement iframe = Document.get().createIFrameElement();
FlowPanel innerBox = new FlowPanel() {
@Override
protected void onLoad() {
super.onLoad();
FlowPanel p1 = new FlowPanel();
p1.addStyleName(resources.css().test());
HTMLPanel panel = new HTMLPanel("Hello World!");
panel.setStyleName(resources.css().test()); // does not work
p1.add(panel);
final Document doc = iframe.getContentDocument();
BodyElement body = doc.getBody();
body.appendChild(p1.getElement());
panel.setStyleName(resources.css().test()); // does not work
p1.getElement().addClassName(resources.css().test()); // does not work
}
};
}
The former code inserts GWT Panels into an iframe. The problem is that I
cannot set any css style. Even if I set the style with:
panel.setStyleName(resources.css().test()); // does not work
p1.getElement().addClassName(resources.css().test()); // does not work
both variants do not work. I know I can inject a general css file in the
head of the iframe document, but I want to use the GWT resources.
*How can I set the styles using CSS/GSS Resources for the Panels inside the
iframe?*

Re: GWT Cross Site Iframe Linker and Script Tags
Hi I know it's an old thread but I used few hours to quickly implement a linker and special entry point class that uses script tags from gwt.xml files and injects them automatically using ScriptInjector. There are few changes required in EntryPoint classes but they are not that intrusive. Could you tell me if such approach is sensible? Do you see any problems it could cause (except difference in performance - scripts have to be loaded one after another instead of almost concurrently).

What happens if compiled script (iframe content) is loaded after outer page is parsed
Hello: Reading the GWT Bootstrap on Googles page http://www.gwtproject.org/doc/latest/DevGuideOrganizingProjects.html#DevGuideBootstrap I wonder what happens if host page is parsed before iframe's contents are loaded. Does it wait for it ? Does it do anything ? I know onInjectionDone() function is called when outer page is parsed ( by script defer ) . And it calls maybeStartModule() , but i don't see if onInjectionDone() performs some kind of checking Thanks and regards -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

iFrame usage any shortcomings that we should we aware of ?
Hi! We are using iframe to render document content fetched from the server. The document on the server could have been created using Word as authoring tool / created via an HTML editor on the client itself. The content on the server is stored in individual items on the server. We need to fetch a certain number of such items in one go and then scroll and fetch more content. Since the content can have it's own formatting we have used the iframe so that the application's styling does not interfere with the document content. Going forward we want to introduce following feature- We are displaying the items in a HTML panel as cell widgets. We want to be able to scroll to the specific content when we select a cell widget and if we select content then we should highlight the corresponding item. In order to achieve this we are thinking of using the GWT cell widget to show content also. Does this sound OK ? are there any limitations on the iframe which makes this kind of selection difficult ? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT Cross Site Iframe Linker and Script Tags
Well, it was a Code Splitting problem. Both SuperDevMode and DevMode works fine with the new linker. Le mercredi 5 novembre 2014 23:21:22 UTC+1, Etienne Lacazedieu a écrit : Hi, I'm preparing a big switch (GWT2.3 to 2.6.1, which may change to 2.7.0 depening on the final release date), and I'm having trouble with the xsiframe linker.. I have no problems with adding script tags in the HTML file. Actually, I wrote a linker (a subclass of CrossSiteIframeLinker), which outputs the list of JS files to a properties file. On the server side, a class reads this file to add script tags (we use JSP). My problem is that we have a rather complex integration process, with several GWT applications on the same page. - a Container app, which creates Desktop-like UI, and exposes some JS native API to interact with other apps. - several Functional apps, each one containing one or more functional modules. Each functional module description is injected to the container app, which creates a launcher command. Invoking the command (done in the container app) triggers the creation of the functional module UI (done in the functional app). When this function returns, the container grabs the new DOM element and creates a Window UI around it. My problem with the XSI linker is that I cannot get it to work as it did before.. In my sample deployment, the container is called SampleGWTContainer, and the functional app is called SampleApplication. I have the following error in the console : $wnd.SampleApplication.runAsyncCallback2 is not a function The odd thing is that when I start SuperDevMode, and recompile SampleApplication, it works. If I recompile SampleGWTContainer, I have the same error. I still have to try to remove the split point, to make know if it is a Linker or a Code Splitting related problem..

App in iframe does top navigation
Is there a way to avoid top navigation for a GWT app in an iframe? I am putting my app into someone else's page, and they are putting it in an iframe. The app takes over the entire window instead of limiting itself to the iframe. If I turn off ALLOW_TOP_NAVIGATION, the app will not run at all. The iframe is just empty. This behavior is counter to all documentation that I have found. Can anyone shed some light on this? Is there a simple way to tell GWT not to use top navigation and to stay inside of the iframe?

get scroll event from iframe
there seems to be no way in GWT to get the iframe scrollEvent.
I tried
(com.google.gwt.dom.client.IFrameElement)frame.addDomHandler(newScrollHandler()
{
@Override
public void onScroll(ScrollEvent event) {
// do something
}
}, ScrollEvent.getType());
but the event does not fire when scrolling
inside the iframe, you can get
Document document = iframe.getContentDocument();
but it does not have methods for adding listeners. there is no method for
returning the contentWindow like in javascript.
any one knows any way to get the iframe scroll event?

I got the pages to not blink, but the back button does not work correctly, you need to click it three times to get to the page it should go to. It was doing this before I made your fix. Well thats expected as you update the URL whenever a navigation inside the 3rd party app occurs. I thought this behavior is the one you already had but with blinking going on. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

gwt navigation with 3rd party app in iframe
I have a GWT application with navigation designed using the samples (Place,Activity,EventBus ...) There is a navigation bar, and a Panel where the actual navigation takes place. In some cases, the panel is filled with a third party app using a com.google.gwt.user.client.ui.Frame iframe. The user can navigate in side the 3rd party app, and my app captures this and processes it with the GWT navigation. The problem is that when the user is on page1 with param1 and they go to page2 with param2, I create Token page2:param2 and do a PlaceController.goTo(place). But this causes the same page to get reloaded, it blinks. Is it possible to simulate the goTo(place) by changing the URL to the new token and adding it into the PlaceHistory? thanks -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

You need to cache the activity that displays the 3rd party app so it does not get recreated in your ActivityMapper each time you navigate inside the 3rd party app. So your URLs should look like /#ThirdPartyAppPlace:app=page1 /#ThirdPartyAppPlace:app=page2param=x /#ThirdPartyAppPlace:app=page3 and for each URL the same activity instance should be returned.

[gwt-contrib] Change in gwt[master]: making RootPanel.clear(true) respects GWT loader iframe

Patch Set 5:

File user/src/com/google/gwt/user/client/ui/RootPanel.java
Line 340:GWT.getModuleName().equals(childElement.getId())) {
- This code does not work with real browsers unless you change it to the
code below, Because Element.hasTagName() is case-sensitive and compares the
argument against getTagName() which always returns UPPERCASE (see:
http://www.w3schools.com/jsref/prop_element_tagname.asp).
childElement.hasTagName(IFrameElement.TAG.toUpperCase())
A simpler solution could be to get the iframe before the loop and compare it
moduleIframe = DOM.getElementById(GWT.getModuleName()) ;
if (!childElement.equals(moduleIframe)) {} ...
- NOTICE: I think we must preserve the 'script' with
the 'moduleName.nocache.js' as well. Some times the user adds it to the
body instead of to the head. I think that if we remove it, XS linker would
not load next fragments.
Out of subject: In these cases I miss css selectors in gwt, something like:
nodesToRemove = DOM.querySelectorAll(body :not(#moduleName));

File user/src/com/google/gwt/user/client/ui/RootPanel.java
Line 329: if (!shouldNodeBeRemoved(child)) {
Deattaching/reattaching an iframe should result in reloading its page, and
I don't think that's what we want:
When an iframe element is inserted into a document, the user agent must
create
a nested browsing context, and then process the iframe attributes for the
first
time.
When an iframe element is removed from a document, the user agent must
discard the nested browsing context.
This happens without any unload events firing (the nested browsing context
and
its Document are discarded, not unloaded).
— Source:
http://www.whatwg.org/specs/web-apps/current-work/multipage/the-iframe-element.html#the-iframe-element
Because it's only about one element (for now, but it should remain only a
handful elements in the future at most), and it's inserted at the end of
the body (well, OK, the module could then add other elements after that,
but the original purpose of clearDom was to clear everything on load), how
about skipping it in each iteration? Would it really slow down things?
while (containerElement.hasChildNodes()) {
Node child = containerElement.getFirstChild();
while (!shouldNodeBeRemoved(child)) {
child = child.getNextSibling();
}
containerElement.removeChild(child);
}
Also, is there really a big difference between hasChildNodes/getFirstChild
and igetChildCount()/getChild(i) ? (and one that matters here, because I
don't expect clearDom to be used that much, and in 99% of the cases it'll
be used to remove a loading message, so losing a few milliseconds
wouldn't really matter as the loading message would still be visible in
the interim)
Another alternative would be to search for the first node that we want to
keep and remove everything before it, and repeat that process until we
reached the last child node. Or even better, mix getFirstChild and
getNextSibling to really walk the DOM, skipping the appropriate nodes:
Node child = containerElement.getFirstChild();
while (child != null) {
Node next = child.getNextSibling();
if (shouldNodeBeRemoved(child)) {
containerElement.removeChild(child);
}
child = next;
}

GWT application in iFrame
Hi, I have a web app and it is called in an iFrame. This contains 2 slider elements and an output element. When the sliders are moved a calculation is fired and displayed in the output element. However, this works fine with all browsers except Chrome. When I move the sliders, the output element is not refreshed. This happens only if I select the result (for example). I use GWT 2.4.

IFrame BlurHandler event target
Is there any way through GWT to get the target of a BlurHandler placed on an IFrame (specifically the one used in the HtmlEditor)? I get the BlurEvent just fine, but getting what it blurred to seems problematic. The getEventTarget() seems to return an EventTarget that is neither a Node nor an Element. Sometimes a JSNI getter for document.activeElement returns the right element but mostly it seems to want to return the entire body element. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

iframe + radio button + flash
Hello: There is a issue in Chrome about pages with flash objects and iframes containing radio button. The problem is a white border around this widget. http://code.google.com/p/chromium/issues/detail?id=141412 In this page there is an example It's a Chrome bug ( and very old , by the way ), but this bug affects in a serious way to all GWT applications running in hosted pages with flash elements. I don't know why , but it looks like radio buttons are renderized inside iframe element and write them out of it. am I wrong ? So, it's a problem : all radio are painted with a ugly white border Does anyone know a workaround ? Setting the background color of the page to white is not a solution for me Does anyone know if Google (Chromium project) is solving this issue ?

Re: GWT Cross Site Iframe Linker and Script Tags

Re: GWT Cross Site Iframe Linker and Script Tags
This sucks great time, now that devmode plugins have been abandoned (surprise!), and Super Dev Mode was forced onto us, xsiframe became a must, and all the GWT libraries and apps that use script tags are not working anymore. What's wrong with document.write anyway? I'm really angry now with Google, and we're going to rewrite the app with JS, Backbone, jQuery, who knows. At least stuff won't break because of ridiculous developer decisions. Thanks Google -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How get iFrame contents with different domains ?
Hi,
You can't directly in GWT it honors cross site scripting you can however
drop down to Javascript. Write a JSNI method that accesses the containing
docs parent (your app) by accessing top, then in your code you can access
the iFrame and then it's document. Something like this:
public static DocumentElement getFrameDocumtent() {
FrameElement top = getTopDocument().getElementById(MyiFrame);
return top.getContentDocument();
}
public static native Document getTopDocument() /*-{
return top.document;
}-*/;
I haven't tested this code but pulled pieces from some of my working code
to give you an idea.
Hope that helps,

Re: How get iFrame contents with different domains ?
After sending this I realized I sent it too early. The code below only
works after you get both documents under the same domain because of
cross-site scripting protection in the browser. To bring them both under
the same domain you can either setup Apache or Nginx as reverse-proxy or
write a servlet deployed with your GWT server side code that proxies
requests to the other domain. If you just have a couple of pages to proxy I
would do the servlet approach. I've done both methods. There are a couple
of example proxy servlets you could start with and deploy one of them in
your web.xml.

You cannot do this the way you want. It is simply does not allowed by the most of browsers.

Re: printing problem: when I print content of my iframe (I use gwt-print-it) all what is left on the right side of printable page is cut off and stays not printed at all
no, I don't want to print double-sided document. let me explain it: imagine you have empty page with just one big image inside 'body' element: body img src=... style=width: 3000px; height: 2200px; / /body lets say it looks like this: http://why.net.pl/tmp/0.png and you want to print WHOLE image. So you'd expect your printer to print something like this: http://why.net.pl/tmp/1_.png but instead of this I'm getting something like this printed: http://why.net.pl/tmp/2_.png so it's not whole image. of course my problem is not about image but very big HTML form that has fixed width and height. This form cannot be resized. Fields on this form cannot be positioned differently, they are positioned with absolute positioning and they have to stay in their places. So my question is: what do I have to do in order to print wide elements that won't fit in one page (when it comes to element's width)? as I previously mentioned I already use gwt-print-it.

Re: GWT calling java from JS doesn't work with Iframe
One way this error can also be caused is that you did not *publish* that public method before you called it. You need to ensure you've got a JSNI method (like the one you posted) that is run onModuleLoad to add your public JS functions to the window's namespace. Of course you can use GWT to set the listener on the *input* element and skip the JSNI bit if you like.

AdSense without iframe
I've been looking for an easy way to include an AdSense DIV in my GWT app without using an iframe and my current approach is as follows: (1) In the application host page (i.e. application.html), I include the standard adsense boiler code and put a @id on the wrapping div like: div id=adsense script type=text/javascript!-- google_ad_client = xx-xxx-; /* OpenDDI 468x60 */ google_ad_slot = xx; google_ad_width = 468; google_ad_height = 60; //-- /script script type=text/javascript src= http://pagead2.googlesyndication.com/pagead/show_ads.js; /script /div (2) To integrate this as a Widget in the GWT application (for example in the header), I rewrap it in an HTML widget that I can then position/control at will: Element adsense = RootPanel.get(adsense).getElement(); HTML adsenseWrapper = HTML.wrap(adsense); Can someone feedback on - whether this complies with Google policies (as it is not wrapped in an iframe and essentially loads when the application page loads)? - would there be any way to rotate the app by calling the embedded javascript (likewise in compliance with policies)? thanks *K -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: preview in case of iframe
The document inside you iFrame is a completely separate document and can be from a different domain as well so won't get any events just like you don't get events from other browser tabs. However you could communicate across the boundary by defining your own api's. What I mean is you can add Javascript methods to the containing document and call them from the child using top.insert method name. What I've done in the past is create 2 entry points (and modules), essentially two GWT apps, one for the parent window and the other for the child window. Using JSNI expose a well know method name on the parent that can be called. It can be a pain but we had an app that could be hosted in another app using a iFrame and could have hot key support for both passing key events to the parent. By the way this only works when both apps are from the same domain.

IFrame to https url not working in Firefox
Hi all, I have an application that is secured with an unsigned ssl certificate. I have a second application, which is a TabPanel, and on one tab I need to include the first application, as an iFrame, using a Frame object. In development mode, in chrome, it returns a 501 (net::ERR_INSECURE_RESPONSE) error, but it works when deployed (you get the warning and you can click continue). In Firefox it does not work. The page is displayed but it seems like no javascript is rendered, you can see only the css background. I assume this is because of the ssl because it's working if I use a random http url (not https). Is there something I can do for this? The fact that it displays a warning before you can continue is not really bothering me, because on real production we can use a paid ssl certificate. Is there another way I can include the first application into the second? The problem is that it is an entirely different application, with a different entry point and HTML structure, that's why I tried to use an iframe.

The problem is that it is an entirely different application, with a different entry point and HTML structure, that's why I tried to use an iframe.

Re: IFrame to https url not working in Firefox
Hi Paul, Thanks for the reply. Sorry, I was misleading in my description of the problem. Yes, the certificate is signed by us, and it generates a browser warning. But the application does not work at all when called from inside an iframe. On 17 Νοέ, 12:18, Paul Robinson ukcue...@gmail.com wrote: Why not sign the certificate yourself? The result won't be trusted, and will generate a browser warning, but it will more faithfully represent what happens in production. Google for something like self signed ssl certificate to work out how to do it.

The page is displayed but it seems like no javascript is rendered, you can see only the css background.

Drag and Drop to a RichTextArea / IFrame?
I'm trying out some of the fun drag-and-drop stuff in GWT. My current
attempt is to drag a file into a richtextarea, but nothing seems to be
working correctly. It works fine if I use a FlowPanel or some other
GWT widget, but not a RichTextArea despite it have an addDropHandler
method.
Anyone have any experience with this?
My code in onModuleLoad:
DropHandler drop = new DropHandler() {
@Override
public void onDrop(DropEvent event) {
event.preventDefault();
String data = event.getData(text);
GWT.log(text is +data+ and there are
+numFiles(event.getDataTransfer())+ files);
}
};
RichTextArea rt = new RichTextArea();
rt.addDropHandler(drop); // never called even after drag-and-dropping
a file on the rt
RootPanel.get().add(rt);

Re: iframe with GWT
Yeah, I know about the Frame element but I don't know how to edit the head and body areas inside of it or pass it HTML to fill itself with. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: iframe with GWT
So I found this
link http://bealetech.com/blogs/sean/2010/01/embedding-html-document-iframe-gwt
and I got it to work using these functions:
final IFrameElement iframe = Document.get().createIFrameElement();
FlowPanel innerBox = new FlowPanel() {
@Override
protected void onLoad() {
super.onLoad();
// Fill the IFrame with the content html
fillIframe(iframe, contentHtml);
// Add a HEAD element to the IFrame with the appropriate CSS
addHeadElement(iframe, cssUrl);
}};
innerBox.getElement().appendChild(iframe);
*and *
private final native void fillIframe(IFrameElement iframe, String content) /*-{
var doc = iframe.document;
if(iframe.contentDocument)
doc = iframe.contentDocument; // For NS6
else if(iframe.contentWindow)
doc = iframe.contentWindow.document; // For IE5.5 and IE6
// Put the content in the iframe
doc.open();
doc.writeln(content);
doc.close();
}-*/;
I tried to get the head function on that page to work, but wasn't sure how to
pass in the HTML and write it to the head element. Right now I'm just using
div style=background-color:red; font-size: 18px;Hello World/div to get
the styles to work with the divs I need them to.
I end up with this in the dom:
diviframehtmlhead/headbodydiv
style=position:fixed;top:0px;left:0px;color:red;background-color: blue;
font-size:44px;Hello World/div/body/html/iframe/div
It works but I would imagine there's a better way.

Re: iframe with GWT
Thanks! This looks awesome! I'll give it a try. I never would've understood enough on how GWT interacts with the DOM to do this myself, but this'll be a very educational exercise for me.

iframe with GWT
I'm wondering how I can create and iframe with GWT and inject some
style type=text/css body{background-color: red;} /style type
of stuff into the head and then inject a bunch of divs into the body.
I don't need to be able to link to them at all or apply any handlers,
so I would think this would be pretty easy, but I haven't found any
good ways to do this yet. I tried using an HTML object and injecting
iframe code into but it wasn't taking it for some reason. Any advice
is appreciated.
Thanks!
Cory

Iframe events
