Re: How do I make alternative style sheets for IE7 etc. in GWT?
You'll find the conditional css is remarkably unreliable in the real world. The list of supported user.agent properties is here though, since it fails to turn up anywhere in the actual documentation: http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/com/google/gwt/user/UserAgent.gwt.xml Supported values are: ie6,ie8,gecko,gecko1_8,safari,opera You'll notice particularly vexingly there is no good way to specify an IE7 specific style rule.

Re: How do I make alternative style sheets for IE7 etc. in GWT?
In theory, if you're only using GWT components, they should already be
styled correctly for all browsers.
In practice, that is only true if your site is entirely GWT; mixing it
up with a little GWT here and there will without fail screw all the
styles up. There isn't really a good solution for the problem; you can
have a look asset bundling though; it has some inbuilt smarts for
browser hacks, but it can only detect IE6. There's some documentation
about that here:
http://code.google.com/webtoolkit/doc/latest/DevGuideClientBundle.html#CssResource
If you're working with a designer that isn't GWT friendly, your best
bet is probably to great the code; and then get them to style it
correctly using a couple of style sheets; webkit, gekko, IE-new, IE-
old, then use a JSNI call to detect browser type;
eg.
private native String getBrowser */-{
// native js detection hackery. :/
}-*/;
Then use a CssResource to inject the appropriate stylesheet:
eg.
String b = getBrowser();
if (b.equals(ie-old)) {
bundle.stylesheetIeOld.ensureInjected();
}
Long story short; mixing non-GWT and GWT is a pain. If you can, stick
to an entirely GWT web app, and you'll find all the browser quicks
should smooth out. If that's not an option... well, good luck with
that~

User.agent detection in CssResource not working?
I'm havign trouble with a CssResource I'm using.
This is my css:
.Box {
border: 1px solid #f00;
}
@if user.agent ie6 {
.Box {
background: #f00;
}
}
It's pretty much straight out of the example here:
http://code.google.com/p/google-web-toolkit/wiki/CssResourceCookbook
The problem is that the user.agent detection doesn't seem to work.
That style is never added...
So I thought maybe I was doing it wrong? Tried this...
.Box {
border: 1px solid #f00;
}
@if user.agent ie6 {
.Box {
background: #f00;
}
} @elif (com.client.Com.Check()) {
.Box {
background: #0f0;
}
} @else {
.Box {
background: #00f;
}
}
where:
public static boolean Check() {
if (Navigator.getUserAgent().toLowerCase().contains(msie))
return(true);
else
return(false);
}
...and as a result the div has a green background on ie, and blue on
everything else.
Anyone else having issues @if user.agent? Did something change in
2.0.3 so it doesn't work the same way anymore?

CssResource user.agent problem?
Sorry if this is a double post; I thought I posted a message about
this before but it's been 24 hours and it still hasn't shown up...
So, long story short, I can't get the @if user.agent syntax to work
in gwt 2.0.3.
Does anyone know how to use this correctly?
This is my style sheet:
.Box {
border: 1px solid #000;
}
@if user.agent ie6 ie7 ie8 {
.Box {
background: #f00;
}
}
@if (com.client.Com.Check()) {
.Box {
background: #0f0;
}
}
@else {
.Box {
background: #00f;
}
}
And this is the code to Com::Check:
public static boolean Check() {
if (Navigator.getUserAgent().toLowerCase().contains(msie))
return(true);
else
return(false);
}
The style output is style background: #0f0 on all versions on IE. That
is, the @if user.agent query string isn't working at all.
I've tried the example here too, and that also doesn't work for me:
http://code.google.com/p/google-web-toolkit/wiki/CssResourceCookbook
I'm sure I've got this working before. Is there a syntax change or
something I should be using? I've seen some example around where
people are going @if user.agent msie7 or example, but that doesn't
work for me either. :(

Re: Authenticate before loading the application
Absolutely, store the files in the data store or something but serve them as though they were normal pages; simply serving a static resource via servlet won't achieve anything. Also; don't use code splitting as a security measure; it's a client side thing, which means it can be avoided. (Yes, I know, it's a server side thing, but _triggering_ it is a client side thing, and you can do that even if the application doesn't want you to). ~ Doug.

Hm. IE doesn't support setAttribute to set event listeners, and GWT
prides itself on not accommodating different browsers for things like
this,
You're best off writing your own.
Perhaps something like this?
public void onModuleLoad() {
final Label l = new Label(This is a label);
setProperty(l.getElement(),onclick, alert('hello'););
RootPanel.get().add(l);
}
private native void setProperty(Element e, String property, String

Well... which is to say, I got a popup saying Hello.
What were you expecting to happen?

Re: How can you wait until GWT is ready externally? (after onEnterModule)
Quick answer is: If you're providing a series of APIs to a third
party, you:
1) Don't want to give them the source code to recompile them
(potentially).
2) Don't want to make their life difficult by forcing them to
recompile.
3) Don't want to step outside of what is 'normal' for a JS library (no
extra custom ready functions...)
I understand what you're saying; yes, linking it all together is more
efficient. Yes, you can bind everything together that way and you
don't need multiple ready functions. Its a great way of building a
rich net app.
However, for JS mashups, you don't want a single page application that
does everything. You want something that compiles into a generic
robust usable JS API, that is easy to use and obviously interact with
other JS APIs.
Incidentally, as I mentioned, the javascript isn't being loaded in an
iframe. I'm compiling in xs (cross site scripting) mode, which means
the JS is added as an inline element in the head. The google code
launcher specifically waits until after everything else before it
launches itself (I presume to ensure the DOM is ready before kicking
off the application init), but I would have been pleased if maybe the
module constructor was run on load, and only onModuleLoad waited until
after body.onload was called. Oh well.
I've come to realize that GWT is ill suited to what I'm doing. I'm
quite disappointed really.

I'm not 100% following your question, so excuse me if my answer does
not match your question.
Why would you need to have a toBeCalledByGWT for every method you want
to expose from GWT ?
I presume you have created an API in GWT and want to expose it outside of GWT
?
Just make sure that the onModuleLoad exposes all the methods (one way
or another) and at the end you just call one method on the window
object to indicate that the API is ready to be used. So you JS code
just needs to wait until that method is invoked before starting
If you want to use multiple GWT APIs this way, I guess the best thing
to do is to have one onModuleLoad that invokes the injection of all
the APIs in JS and then call one callback to kickstart your
application. The idea of GWT is that you compile everything in one
application to improve optimisations and to have a small as possible
JS.
Why is the GWT API not fully initialized ? Well because it is
actually loaded by a hidden IFrame. Additionally with GWT 2.0 we will
be able to actually load parts on demand through runAsync support.

Re: JSNI for non-static functions.
For anyone else, attempting to do this: It's not possible.
GWT doesn't maintain the 'this' context, as I suspected.
The best work around I've found for this is below.
Note 1) the odd syntax, something about JSNI means typical JS
{ 'name' : ... , 'name' : ... } syntax doesn't compile, and 2) we
exploit Js's stack to preserve the self context in the javascript call
(but that's pretty standard fare).

public void onModuleLoad() {
init();
initStatic();
}
private static Object instance() {
Object rtn = (Object) new demo();

Re: Hint: Previous compiler errors may have made this type unavailable
I don't know if this will help, but check your paths. If you have a source path like this: C:\Workspace\App\src\com\me\app: - App.gwt.xml - App.java Where App.gwt.xml reads: ?xml version=1.0 encoding=UTF-8? !DOCTYPE module PUBLIC -//Google Inc.//DTD Google Web Toolkit 1.7.0// EN http://google-web-toolkit.googlecode.com/svn/tags/1.7.0/distro- source/core/src/gwt-module.dtd module rename-to='app' inherits name='com.google.gwt.user.User'/ inherits name='com.google.gwt.user.theme.standard.Standard'/ entry-point class='com.me.app.App'/ /module You will get an error like this: Compiling module com.me.app.App Computing all possible rebind results for 'com.me.app.App' Rebinding com.me.app.App Checking rule generate-with class='com.google.gwt.user.rebind.ui.ImageBundleGenerator'/ [ERROR] Unable to find type 'com.me.app.App' [ERROR] Hint: Previous compiler errors may have made this type unavailable This is because GWT is (very) not smart, and cannot locate classes in the small path as the gwt.xml file (notice how the template projects always have a client and server directory). So fix this, change the class path of App.java to: C:\Workspace\App\src\com\me\app\client And the entry point to: entry-point class='com.me.app.client.App'/ This may not be the problem you have, but it sounds quite similar. Don't worry. It's not just you. I've never come across a good explanation of why this happens. ~ Doug. On Jul 24, 6:44 pm, BMax massimo.bo...@gmail.com wrote: Thanks mirceade!
