Re: Is it possible to use CSS Rem unit in GWT 2.0 layout system?

[Craig Mitchell]

You should be able to set it directly, something like this:

myPanel.getElement().getStyle().setProperty("margin", "rem(14%, 3%)");

Is it possible to use CSS Rem unit in GWT 2.0 layout system?

[Chak Lai]

Greetings,

Is it possible to use CSS Rem unit in GWT 2.0 layout system?

I have a legacy GWT project that uses GWT 2.0 layout system. The project 
has been upgraded to gwt-2.11.0 successfully. However, I notice the current 
Enum Style.Unit in the com.google.gwt.dom.client package does not include 
REM unit for CSS Viewport. I have trouble extend the project to mobile 
device or small screen.


Thanks.

Does GWT support negative REM (CSS) values?

[Colleen Todd]

Just curious. I have a couple of negative rem values that keep getting 
converted into positive values in real life. 

i.e. -1rem will actually come out as 1rem

Re: TabLayoutPanel looses its CSS style when placed in a CSS- grid container

[Craig Mitchell]

Ah, yes.  You want to call addStyleName, not setStyleName.  I think you 
call addStyleNames via the UIBinder.

This did not help.
But maybe I found the real issue:
To place the TabLayoutPanel in a CSS grid container, I added a
styleName="{style.c1}" attribute to the TabLayoutPanel in the ui.xml.
Setting a styleName seems to replace the existing CSS styles completely (for a 
DataGrid, this is not the case).
As a workaround, I had to wrap g:TabLayoutPanel in a .

Re: TabLayoutPanel looses its CSS style when placed in a CSS- grid container

[Craig Mitchell]

Odd that it would lose the CSS.  You could try putting in the CSS 
yourself.  You can copy it from here  
http://samples.gwtproject.org/samples/Showcase/Showcase.html#!CwTabLayoutPanel  
or from the standard.css file in your project.

TabLayoutPanel looses its CSS style when placed in a CSS- grid container

[Martin Weber]

Hi,
 I'am faced with a weird issue.
When I place a TabLayoutPanel in a CSS grid container, the header tabs are 
displayed as plain text.
No margins, coloring etc.
In the browser's HTML inspector, I see that the tab header elements have 
the class attributes set tho the GWT-styles for TabLayoutPanel. But somehow 
the GWT stylesheet/ styles are missing.
What am I doing wrong? 
Any suggestion to make it work?

In contrast,  a DataGrid placed in the same CSS-grid container looks fine.

TIA, Martin

Re: Migrating a css file into gwt uibinder

[Craig Mitchell]

I never figured out how to add the @keyframes in the GWT resources.  As a 
workaround, you can add the CSS like you would a standard site.  Eg, in 
your index.html like this:

  @keyframes fadeIn {
0% { opacity: 0 }
100% { opacity: 1 }
  }


Then in your ui.xml, you can just refer to it as normal.  Eg:
blah

Not an idea solution.  If anyone knows how to add @keyframes to the 
resources, that would be very helpful.

Migrating a css file into gwt uibinder

[Gary Barnes]

I have a Display panel that contains an image that displays a gif spinner, 
however the spinner just doen't look great. 
So want to replace the gif spinner with something else, well I found a css 
file that looks a lot more like what we expect. Question is how do I 
migrate the css spinner into my panel?

Existing code snippets
Panel.ui.xml 

  
.apwidth {
  width: 100%
}
.
.
.
  
  

  

  
  Sys 1

  


Panel.java
class Panel extends Composite
{
private static final PanelUiBinder uiBinder = GWT.create(PanelUiBinder.
class);

interface PanelUiBinder extends UiBinder
{ }

interface Style extends CssResource
{
String grey();
String red();
String yellow();
}

@UiField
Style style;
@UiField
Image   SpinnerUp;
@UiField
Label   HardwareStat;

Panel
{
initWidget(uiBinder.createAndBindUi(this));

SpinnerUp.setUrl("images/load16.gif");
.
.
.
}
.
.
.
}



Want to integrate this:

Re: Using StyleInjector with Polymer and Custom CSS Properties

[Tyler Moore]

Made a workaround for this.

Instead of using StyleInjector. I just created a wrapper class that treats 
it like a mundane style element with loaded innerHTML from the resource:

public interface CSSStuff extends ClientBundle {

public static final PageCSSResources INSTANCE = GWT.create(PageCSSResources.
class);

@Source("styles.css")
TextResource siteCss();

}

//...Somewhere else
StyleElement element = Document.get().createStyleElement();
element.setInnerHTML(CSSStuff.INSTANCE.siteCss().getText());
Document.get().getHead().appendChild(shared.getElement());

Using StyleInjector with Polymer and Custom CSS Properties

[Tyler Moore]

I use StyleInjector to inject CSS rules that work with Shadow DOM Custom 
Properties: https://www.polymer-project.org/2.0/docs/devguide/shadow-dom

A snippit from the CSS I inject:

event-action-table.event-action-list-editor {
--table-height: 200px;
a-property-with-no-double-minus-prefix: 0;
}

A snippit from the custom element template:

vaadin-grid {
  width: 100%;
  height: var(--table-height);
}



However, at run time, it looks like anything that is prefixed with '--' 
get's ignored by the injector. In the above case, my output element style 
looks like:
event-action-table.event-action-list-editor {
a-property-with-no-double-minus-prefix: 0;
}

Why is that?

Eclipse fails to serve CSS file

[Velusamy Velu]

My GWT application development ran into a problem that poses a challenge to 
resolve. The application is developed with GWT 2.7.0 and a pilot is running 
at PeruseLabs <http://peruselab.com> (the Pilot Screen clip is below). This 
application has been in development for quite some months. However, in 
development the CSS file *PeruseLabs.css* doesn't seem to be loading (I 
don't see any evidence that it's loading). This started happening since mid 
January 2018. The CSS (*class icon*) loads as expected in the pilot  but not in 
development (Dev Screen clip all the way down). To reiterate - when this 
project is built and deployed in "prod" it works as expected. The 
development has come to a screeching halt though.

The corresponding icon class is 
.icon {
width: 45px;
margin: 7px;
border-radius: 5px;
cursor: pointer;
}

My development environment is -
Java 8 (Ver 1.8.0_151)
Eclipse Oxygen
GWT 2.7.0
GWT Eclipse Plugin: Version 3.0

Any idea what could be wrong? Thank you in advance.

Injecting CSS and JS into UiBinder - Issue with getting access to image path

[Muhammad Zbeedat]

Hi,
I'm trying to implement a JS library (VisJs: http://visjs.org/) in my GWT 
project.
So, in order to use it from my UiBinder I used the ScriptInjector:
ScriptInjector.fromString(JsResources.INSTANCE.visScript().getText()).inject();

and in ui.xml I used the following:
 .htmlPanel { font-size: 
12px; font-family: Verdana, Geneva, sans-serif; border: 1px; border-style: 
solid; border-color: #969696; margin-top: 10px; } 

in my project I created a folder called resources as follow;

   - resources
   vis.js
   vis-min.css
  - img
 - network
  
in my gwt.xml i added: ** in order to get 
access to these resources.

The script is working for me and loading the graph, but not completely. I'm 
getting such errors:

vis.js:52995 GET http://127.0.0.1:/css/img/network/cross.png 404 (Not 
Found)

Somehow the "css" is part of the url and images can't be found!
Can you please advise how to fix it?

GWT itself uses a version of Google Closure Stylesheets library internally 
to support CSS 3 features. GWT updates this library from time to time to 
support more CSS 3 features and it looks like CSS variables are not yet 
available in Google Closure 
Stylesheets: https://github.com/google/closure-stylesheets/pull/121

For now you have to stick with closure stylesheets 
variables: https://github.com/google/closure-stylesheets#variables

CSS Variables and GSS

[max . dubiel]

Hello Folks.

It's tricky so far to find anything regarding this topic. It's alwas about 
GWT CSS Konstants and such. So I hope I don't open an existing topic.

I wanted to start using CSS Variables (the real deal) 
<http://caniuse.com/#feat=css-variables>. Turns out the GSS compile doesn't 
like the syntax. Did I miss something, or is that just not supported yet. 
And if so, will it be and when?

This line in 2.7 doesn't match with the exception being 
thrown:

It does match in 2.6.1 
though: 
https://github.com/gwtproject/gwt/blob/2.6.1/user/src/com/google/gwt/resources/css/GenerateCssAst.java#L361
Do you maybe have a mix of 2.7 and 2.6 in your classpath?
That said, NativeHorizontalScrollbarTransparent.css hasn't changed since 
its introduction in 
2011: 
https://github.com/gwtproject/gwt/commits/2.8.1/user/src/com/google/gwt/user/client/ui/NativeHorizontalScrollbarTransparent.css
so this is quite strange…
Do you maybe have some third-party library (or your own project) shadowing 
that CSS?

Re: GWT gwt obfuscation (gwt-style=OBF) generates invalid css

[Hannes]

Hi,


this post was a mistake by myself. I assumed that obfuscation would cause 
the problem. As I learned now it has nothing to do with obfuscation but 
with minifying the css. We used yui-compressor which has a known bug when 
it comes to @media and ... So we just need to switch the tool for minifying 
the css.

Sorry for the mistake

Re: CSS resource not found in GWT library

[Jens]

You can always reference resources in ClientBundle using relative paths. 
Doesn't matter if its in src/main/java or src/main/resources. 

src/main/java/com/example/client/MyClientBundle.java
src/main/(java | resources)/com/example/client/std.gss

=> you can use @Source("std.gss") or completely omit it if your method is 
named std().

I only use absolute paths for CSS files I import, e.g.

@Source( { Constants.CSS_FILE, "std.gss" }) with CSS_FILE being absolute

Re: CSS resource not found in GWT library

[Magnus]

Ok, and when doing it the "usual" way - placing the resources in 
src/main/resources - can you shorten the references inside the ClientBundle 
java file somehow, i. e. avoid to specify the whole path for every resource?

Thanks
Magnus

Re: CSS resource not found in GWT library

[Jens]

Normally when using Maven anything that is not a *.java file should go into 
src/main/resources. However if you prefer certain resources to be closer to 
your java source files by placing them into src/main/java then you have to 
add an include for these files as you have already done for *.gwt.xml (and 
*.java because it is a GWT library jar).

CSS resource not found in GWT library

[Magnus]

Hello,

while building a GWT application I get these errors:

[INFO] Compiling module msm.app.bcs.Application
[INFO]Computing all possible rebind results for 
'msm.lib.acs.awi.client.res.Resources'
[INFO]   Rebinding msm.lib.acs.awi.client.res.Resources
[INFO]  Invoking generator 
com.google.gwt.resources.rebind.context.InlineClientBundleGenerator
[INFO] Preparing method css
[INFO]Finding resources
[INFO]   [ERROR] Resource std.css not found. Is the name 
specified as ClassLoader.getResource() would expect?
[INFO] Preparing method help
[INFO]Finding resources
[INFO]   [ERROR] Resource Help.png not found. Is the name 
specified as ClassLoader.getResource() would expect?


The missing resources std.css and Help.png are part of a jar library used 
by the application.
They are referenced by a ClientBundle:

Resources.java: // references the resources:
- Help.png
- std.css


The jar file is built using a pom.xml, which adds the sources like this:


  

  src/main/resources


  src/main/java
  
msm/lib/acs/awi/**/*.java
msm/lib/acs/**/*.gwt.xml
  

  



As you can see, only *.java and *..gwt.xml files are included, but no *.css 
or *.png files.

But how do you include them properly? Should I add an include statement in 
the pom.xml above? Or should the resources be placed at another location? I 
think it's good to have them near the ClientBundle java file.

How do you do this?

Thanks
Magnus

No, I have no idea about the autoprefixer API. In terms of GWT you would 
likely need to copy CssResourceGenerator and GssResourceGenerator and then 
add autoprefixer in the appropriate places.

But honestly, autoprefixer is a processing tool that should run outside GWT 
but before the GWT compiler runs. In GWT 3 there are no generators anymore 
so you would need to run it externally anyways. So you better find a good 
external solution instead of hacking GWT.

Re: Using css autoprefixer with GWT

I use GSS mixins. Works ok for me, usually you don't need a lot of prefixes 
to maintain.

To automate it you would need to call autoprefixer programmatically in a 
resource generator or use a file watcher (IntelliJ has a plugin for it, 
otherwise use grunt or so) that triggers autoprefixer whenever a *.css / 
*.gss file changes.

Using css autoprefixer with GWT

[harshyadav]

Hi,

We are trying to use autoprefixer in our GWT application for vendor 
specific rules especially for flexbox support:
https://github.com/postcss/autoprefixer

We can run this independently and update each stylesheet manually, however 
its not ideal solution and time consuming/error-prone.

Does anyone has experience automating it with the GWT compiler?

Thanks!

Re: styling Uibinder with external css using background image

[NewbieGwtUser]

Any help please on this point ?

I know that my problem is resolvable using the simpliest manner of 
ClientBundle with both solutions of cssResource or ImageResource. But, I 
really want to optimize my gwt project with the use of gss since 
cssResource will completely disappear with the coming of GWT 3.0 as it's 
mentioned in this blog 
<http://blog.lteconsulting.fr/gwt/2015/06/10/gwt-meetup.html>.

big thanks for any helpful idea.

Re: styling Uibinder with external css using background image

[NewbieGwtUser]

Hi ! thanks first for your reply.

Actually, I've already investigated around this track using the gss 
mechanism, following exactly what is mentioned in this tuto 
<http://blog.arcbees.com/2015/04/14/getting-started-with-css-gss-gwt/#resource-loader-file>
.

So I created the gss file instead of the css and so... but, was blocked at 
the ResourceLoader binding class (which has to be within the ClientModule 
class extending the AbstractPresenterModule class of the gwtp framework), 
since I'm using the mvp4g API instead.

So I'm wondering if there is any way of replacing the ClientModule class by 
the appropriate one in the mvp4g to get the ResourceLoader binding work?

thanks a lot for your help !

styling Uibinder with external css using background image

[NewbieGwtUser]

Hello everyone,

Since two days, i'm struggling to find a tip for showing an image as a 
background within my uibinder file but I were unable to get it work.

Actually I've a gwt-maven project with of course an src/main/java and 
src/main/resources structure. In this latter, I've made a public directory 
in which a set my images and external css files et defined a css class with 
a background-image.

Then, when I called this style within a uibinder .ui.xml file, and tried to 
run it, the image used as the background fails to be loaded at the browser 
page.

(error msg when I inspect with developer tool: Failed to load resource: the 
server responded with a status of 404 (Not Found))

PS: I notice that external css file styles are already referenced in the 
module configuration file (with .gwt.xml extension) and work fine.

Any idea will be very appreciated.

Re: How to get ride of gwt theme css

[Ahamed]

If you don't want to use GWT theme then comment the GWT theme from 
module.gwt.xml

  

The above 3 default theme will come with GWT application.

Comment this if you don't want to include.

Make sure gwt-dev.jar is first in class path. Most likely some other 
libraries you are using are also using flute but with a different/older

Re: CSS exception compiling 2.7.0 app

[Thomas Redman]

Hello? Is anybody out there?

I have several GWT apps, I am having this issue with all of them, it's very 
freaky. The problem stems from one particular css file, 
 NativeHorizontalScrollbarTransparent.css, which has a defined attribute 
who's name includes a "_". I'm not a CSS guy, but this seems perfectly 
legal to me.

Changing this CSS file in the jar file fixes the issue, but that is a 
horrible solution, the parser appears to be broken(actually, the BNF used 
by the parser). The exception comes from the flute parser, and as I 
understand, the BNF does not include the "_", so I think flute is only 
doing what it knows to be right. So what's the deal? Why doesn't everybody 
see this issue?

CSS exception compiling 2.7.0 app

[Thomas Redman]

I reinstalled Eclipse and the GWT 2.7.0 plugin today, and I have not been 
able to "GWT compile" my app since. It is complaining about a css file("
/com/google/gwt/user/client/ui/NativeHorizontalScrollbarTransparent.css") in 
the gwt-users.jar file, but when I extract this file and look at it, I see 
nothing wrong, and there is fact very little in there. 

The exception looks like this:

Re: if change css, need restart the server?

[Dániel Hári]

The problem is that in dev mode the src webapp folder copied to target only 
at startup, and DevMode does not refresh it. As a workaround you can use 
copy-resources 
,
 
that take care of applying changes on the fly.
here is the solution: http://stackoverflow.com/a/37774260/1386911

I found a way as a workaround use maven-resources-plugin copy-resources, this 
updates on the fly your target with every changes in src webapp.


maven-resources-plugin
3.0.1


copy-resources

validate

copy-resources


${project.build.directory}/gwt-webapp

I have an original html like below:


  
  

  

   



 
 
  

   



 
 
  

   



 



I must use GWT for this original html. I can use GWT.create() 
and CssResource.ensureInjected() to inject css into top . Because the 
injected css is not available for frame, I have to inject these css into 
frame. I don't know why the following code doesn't work:

ClientBundle globalClientBundle = GWT.create(GlobalClientBundle.class);
globalClientBundle.css().ensureInjected();
NodeList frameNodeList = document.getElementsByTagName("frame");
int length = frameNodeList.getLength();
logger.info("frame size=" + length);
for (int i=0; i in html code.

What do you mean by "the others"?
What do you mean by "the UiBinder way"? You said this is not using UiBinder 
currently, so do you want to migrate to using UiBinder or just using the 
"same underlying mechanism"?
In any case, have you 
read http://www.gwtproject.org/doc/latest/DevGuideClientBundle.html 
(specifically the part about CssResource, and don't miss 
http://www.gwtproject.org/doc/latest/DevGuideGssVsCss.html, as the specific 
syntax described in the previous link *will be *deprecated in 2.8)

It's hard to help further without knowing what you currently have and what 
you want to change about it.

I am supposed to separate styling part from a Java file (It doesn't have a

Here's what I need to do:

Re: migrating from css to gss (gwt 2.7) - CellWidgets compile errors ?

[Julien Dramaix]

The old CssResource (before GWT 2.7 or GWT 2.7+ without enabling GSS)
doesn't support several CSS3 syntax. If you want a full CSS3 support in
GWT, you have to turn GSS on.
That doesn't mean that you have to use GSS syntax because GSS is a superset
of CSS. It offers several additional features above CSS that you are not
obliged to use if you don't want them.

If you use SASS, LESS or other CSS preprocessor language, you have first to
compile it in pure CSS before to compile your GWT application (except if
you have a generator that is able to compile this preprocessor language).

Re: migrating from css to gss (gwt 2.7) - CellWidgets compile errors ?

[Stefan Falk]

Hi!

I just had the same issue using this Vaadin library, or rather say while 
testing it. 
What does this mean exactly? That GWT 2.8.0 won't support CSS at all and 
that I will have to convert all the CSS into GSS? 

I am asking because in that case I wouldn't even start to use CSS.

BR; Stefan

Adding that in .gwt.xml fixed the same problem for me.

CSS import without any prefix?

[Marcin Okraszewski]

Hi,
Is there any way to use @CssResource.Import but without applying any prefix 
to imported classes? So it behaves similar as extending the CSS interface 
with the base one annotated with @CssResource.Shared. The problem with 
extending the interface is that it requires to write all classes in CSS 
that were declared in the base interface. CssResource.ImportedWithPrefix 
with empty prefix ("") doesn't help - there is still "-" (dash) added in 
front. 

As of use case. We have a design team that is witting CSS that then are 
used directly in GWT. We still want to use advantages of CssResource, but 
it would be difficult to tell designers that here they should write the 
prefix and there not. Especially that they test CSS with a plain HTML, so 
that would not even work.

Thanks,
Marcin Okraszewski

As I see it, the problem is that the request goes to the CodeServer rather 
than your web server (DevMode?)
How do you launch the app (which URL), and what URL reference is used to 
link to the MyStyle.css (and by which mean is it loaded) ?

CSS ignored in SuperDev Mode GWT 2.6.1

[Davide Micheletti]

Hi all,
i just upgraded my GWT apps from 2.5.1 to 2.6.1 and i start the SuperDev
Mode.
It compile everything right but when i launch the app my CSS file is
ignored.
Here the Warn
[WARN] ignored get request: /MyStyle.css

The strange thing is that not all the css is ignored but only the css that
overwrite the default widgets css.

What can i do?

Thanks.

Set css from GWT (dynamically) to element with multiple styles associated.

[Jan Zet]

I have an instance of TabLayoutPanel where number of tabs would be set 
dynamically. Therefore to align tabs to fill whole width of the screen I 
need to

1) Override gwt-TabTayoutPanel default value width 16384px with auto 
!important (done);

2) Set width of gwt-TabTayoutPanel*Tab* to proper percentage value (e.g. 2 
tabs = 50%. 3 tabs = 33%, 4 tabs = 25% and so on). I have a simple function 
for that which goes like this (simplified):

Math.floor(getWidgetCount()/100 + "%");

(done)

3) Now here goes my question: how can i set the width of gwt-TabTayoutPanel
*Tab* from Java? I bolded *Tabs* because when i use this.getStyleName(); i 
got in return gwt-TabLayoutPanel not gwt-TabLayoutPanel*Tab* .

In sum, I can divide my question in two:

-how to access TabLayoutPanel*Tab* css class from GWT?;

-how to set said class width with my dynamically generated percentage 
number?;

My additional thought: Is GSS can do this?

Re: migrating from css to gss (gwt 2.7) - CellWidgets compile errors ?

[Julien Dramaix]

In GWT 2.7, you need to enable the automatic conversion of css file by 
setting the configuration property CssResource.legacy to true:




In GWT 2.8, the compiler will choose the right resource file according to 
your configuration (GSS enabled or not)

Widgets have not yet been updated to GSS; it should be done by the 2.8

migrating from css to gss (gwt 2.7) - CellWidgets compile errors ?

['Thomas Lacroix' via Google Web Toolkit]

Hi,
I am migrating from css to gss using gwt 2.7 and the compile fails :

 Computing all possible rebind results for 
'com.google.gwt.resources.client.CommonResources.Bundle'

the converter tool or turn on auto convertion in your gwt.xml file. Note: 
Autoconversion will be removed in the next version of GWT, you will need to 
move to gss.Add this line to your gwt.xml file to temporary avoid 
this:

The errors goes away with the flag


Am I doing something wrong or does it mean CellWidgets are not compatible 
with GSS for GWT 2.7 ? If do will it be for the next release ?
Thanks,
Thomas

Re: How to dynamically load css style in GWT-based application

[Ltearno]

Hi !

The tool HexaCss for GWT answers exactly your needs (as i understand them).

With it you can produce several CSS files for the same GWT application (and 
still using them in a type-safe way, like with CssResource) and you can 
then change them dynamically without reloading the application.

Here is the link to the tool (open source on github)
http://www.lteconsulting.fr/hexacss/

I hope this helps you !

Thanks
Arnaud

Re: New library to integrate any CSS framework with GWT

[Arnaud TOURNIER]

Hi again Ed, sorry i realize i didn't really answer your question !

So as for the size, the generated CSS file size for the whole app is ~20ko
so i consider it is ok to download it from a  tag in the host page.

I see a potential optimization where the server could embed the default
theme in the host page, in order to avoid the network round-trip to load
the css file. But since the production application i made with this project
is accessed from a LAN, i didn't yet put any effort in that direction.

I shall soon produce a roadmap for this HexaCss, so that if people are
interested, i can prioriticize the features and organize contributions...

Thanks
Arnaud

Re: New library to integrate any CSS framework with GWT

[Arnaud TOURNIER]

Hi Ed,

This project is indeed used in one big application in production (100k+ loc
on the client side).
I use it mainly to maintain 3 different themes for the application (testing
env, preproduction and production). This allows my users to visually know
which platform they are using.

Because it works well, i had the idea to extract it from the main project
and give it to the community.

So of course, there might be some work to be fully industrialized, in order
to adapt to any context.

Any contribution, idea and so on is of course welcome !

Thanks

Re: New library to integrate any CSS framework with GWT

[Ed]

I am curious to the reaction of the gwt dev team member.
Maybe you should drop this in the contributor gwt forum.

I like your approach but ..
In my experience css/html should be put as much as possible outside of gwt, 
and the html/css should by lazy loaded when needed, a bit like RedHat errai 
is using. Some advantages:
1) Flexibility: changing html/css with changing code. 
2) Css/Html experts are much easier to find.
3) Faster changing of css. Css changes in gwt are not always fast because 
java isn't well suited for it, java is verbose, especially when working 
with themes (references from css to static methods for example).
4) Better integration/binding of the html/css with existing published cms 
files (json/xml)
...

This results in a much higher productivity, especially when you have all 
clients wanting their own themes/styling, and gwt developers are very hard 
to find. (I tried different approaches: putting all css/html inside gwt 
(cssresource), outside, a mixture, etc..)

I would love to see that GWT core incorporate some of the Errai 
templating/binding mechanisms in the future.
(I am planning to play with some of the errai mechanism and make it work 
with my current cms xml files I use... I just have to find some time :(

just my 50 cents.

New library to integrate any CSS framework with GWT

[Ltearno]

Hello Everyone,

I come up here to let you know about a library i build, aiming at* 
integrating efficiently any CSS framework with GWT*.

This allows your application to type-safely use *Sass, Less, Susy, GSS, 
vanilla css or any other*.

>From the developper point of view, it *works almost the same way as 
CssResource* which is the default in GWT.

Link : http://www.lteconsulting.fr/hexacss/

Benefits :

 - you can use *any css framework* and not only GSS (especially Sass and 
Less have a very good variable and mixin systems)
 - you can bind* multiple CSS files to one GWT application*. This allows 
you to theme your application in a very effective way
 - you can then *switch your application theme dynamically* without 
reloading the application
 - there is *still optimization happening* : non used CSS classes will be 
pruned. Also there is name obfuscation, for reducing CSS file size
 - the *API is very similar to CssResource* so you don't have much to learn 
to use it.

The product page is here : http://www.lteconsulting.fr/hexacss/
The product page tells you how to use it, how to build it. It has three use 
case demos.
The project is hosted on github : https://www.github.com/ltearno/hexa.tools

Of course, it is open source and will stay so !

Stay tuned, because i have other announcements to make soon

Please tell me if you find the idea interesting and if it might help you. I 
also very much welcome anyone wishing to contribute to this project !

Thanks

Simple tool for generating CssResource files from css/gss stylesheets

[Ali Akhtar]

Its often a pain to have to generate CssResource files from .css / .gss 
stylesheets.

Intellij has a tool that works reasonably well, but it seems unable to 
handle classes with hyphens or numbers in them. E.g it converts both 
"foo-bar-1" and "foo-bar-2" to "fooBar()", which results in compile errors 
due to duplicate methods.

This is especially a problem with Bootstrap and Foundation, where its very 
common to have classes in the "foo-bar-N" format. Intellij also seems quite 
slow at doing this for large files.

I've written a quick tool which should simplify the process, 
at: https://github.com/aliakhtar/EzGss . The readme file describes the 
usage + some examples/

It handles almost all formats in css class names, and it also handles 
reserved java keywords.

Feedback / pull requests welcome.

I have already said it before: in case of old css a constant might be used 
in one file but is defined in a different file. In case of gss you might 
use a @mixin in one file but that @mixin is defined in a different file.

Because GWT can not convert it on a file-by-file basis. All files need to 
be merged to get complete information for parsing. So all files need to be 
of the same type.

Re: [ERROR] Only either css files or gss files are supported on one interface

[Ed Bras]

Thanks for the explanation @Jens. I think I understand why the extension is
important. So we can't  let go if that requirement.
But let's go back to the original error (subject of the topic).
If I understand you correctly, I could be able to mix css and gss files by
using the correct extension. In case it concerns a css file, the gss
mechanism will sue the css2gss converter to create the gss file before
passing it to to the closure compiler. But that is what I am doing, so why
isn't that allowed?

Re: [ERROR] Only either css files or gss files are supported on one interface

[Jens]

What you are asking for is simply not possible in a reliable way under the 
requirement that old css syntax needs to be converted to gss syntax to 
avoid producing compile errors when activating GSS for a project.

When I give you (which is hopefully similar to your use case):

@Source({ app-constants.gss, library-constants.css, library-mywidget.css, 
app-mywidget.gss })

Then what should GWT do to produce valid GSS code that can be handed over 
to closure stylesheets? 

- The ordering of files is important as later files can override CSS rules 
in previous files (e.g. library-mywidget could produce a red widget by 
default and app-mywidget overrides it to a blue gradient)
- Any css file might be compatible with GSS as-is but maybe it is not. If 
you can not use the file extension to decide it you need to try parsing a 
css file using a GSS parser. If it fails it is incompatible and would need 
to be converted using the css2gss in-memory converter.
- app-mywidget.gss might reuse constants provided by library-constants.css 
as well use constants from app-constants.gss.


So what would you do now?

1.) You can not try parsing each file one-by-one to figure out if it is GSS 
compatible because each file might use constants provided by other files. 
If the parser does not see the constant definition it would fail even 
though the file might be GSS compatible. The parser needs complete 
knowledge.

2.) Because of the previous you need to merge all files before parsing so 
you have all information available. Parsing the merged data might work if 
the css files are GSS compatible in which case you would hand over the 
merge result to closure stylesheet to parse it again and produce the final 
css output. However if the merged data fails to parse then you know that 
some files are incompatible but not wich ones. So you don't know if its 
because of a GSS syntax error in one of the gss files (in which case you 
would fail the compile) or if its because one of the css files contain 
legacy syntax that needs to be converted using the in-memory converter.
To figure that out you would need to assume that css files are 
incompatible, merge just the css files (because of 1. and because the 
converter does not want gss input)), run them through the css2gss converter 
and finally merge the conversion result with the remaining gss files. 
However when doing so you might have changed the ordering of css rules that 
needs to be avoided as it changes rendering behavior.

So the only way to make it fool proof for GWT is to assume that *.css files 
must always be converted and that *.gss files can be used as-is and that 
you can never mix them for a given CssResource. And that is exactly what 
GWT does.



So in your case you need to provide gss and css files for your widgets. You 
can generate the gss files from the css files by using the css2gss tool 
provided in gwt-user.jar. GWT itself does the same for its widgets.

Re: [ERROR] Only either css files or gss files are supported on one interface

[Ed Bras]

Thanks @Jens, I understand what you mean.
However, I still not see a could reason to force the gss file extension. I
think we can assume that the developer knows what he is doing and it's his
responsibility to feed the gss engine with the correct files, giving him
the freedom to use any extension he wants.

I understand that it's a nice separation, and it's how other css generation
tools work.
But Gwt is a bit different and does more then just css generation, so in
this case it has some blocking disadvantages.
Advantages of allowing the css extension: shared code use, merging to gss
step by step.

Let me explain it through my use case:
I have a gwt code base that exists of many widget having their own resource
bundle and css files (empty mostly, following to the adapter pattern).
New projects want to use css3 features, as such need the gss mechanism.
However, these shared resource bundles can't be changed, as it results in
breaking other projects using them. Neither do I want to change them as
mostly they concern empty css files that aren't gss dependent, which they
would look like it if they have the gss extension.

To solve this I see 2 options: duplicating the shared css files and giving
them the gss extension -> a lot of work, messy maintainable code.
Patching the gwt gss engine to allow for css files with the css extension.
I think I go for the last option as it seems an easy one looking at the gss
code.

I would suggest to allow for the css extension. Optional with a console
warning that can be suppressed (like done in other parts of the gwt code).

I understand that the css files might contain some gwt syntax like @def
that might result in unwanted results when processed by gss. But isn't that
the same as letting Spring eat some hibernate syntax that it understands
and results in strange outcome It's the responsibility of the developer
to overcome that So give him that freedom

What do you think?
Just my 50 cents.

Re: [ERROR] Only either css files or gss files are supported on one interface

[Jens]

Ok put differently:

When you enable GSS then GWT will use the GssResourceGenerator which 
accepts valid GSS and hands it over to the closure stylesheets backend to 
produce the final css output. Your css files could contain CssResource 
specific extensions like @def, conditionals, sprites, etc. and most of them 
work a bit differently in GSS. GWT can not assume your css file is a valid 
gss file, thus the css file must run through the css2gss converter before 
it will be handed over to the closure stylesheets backend.

I am very sorry Jens, but don't really understand your explanation.
Why can't the css file be used as gss file?
If I look at the examples of gss files, they can contain standard css
content.

Re: [ERROR] Only either css files or gss files are supported on one interface

[Jens]

If you have a mixture of *.css and *.gss files referenced in @Source then 
you can not convert the css files one by one because a css file might not 
contain @def rules if they are defined in a different file. As you must 
also honor css rule ordering the only right thing to do is to merge all 
these referenced files in the same order they are referenced in the @Source 
annotation and then convert it.

However when doing so the in-memory css2gss converter would get a mixture 
of gss and css syntax as input but it only understands normal css as input 
(it builds a AST from the input and recognizes CssResource features during 
parsing). So at the end the converter requires pure css input. It does not 
understand any gss features.

I would create a branch, run the Css2Gss class to convert all css files to 
gss and then start updating @Source annotations and/or String constants 
pointing to old css files.

[ERROR] Only either css files or gss files are supported on one interface

[Ed]

Why does GSS throw the following error when combining CSS and GSS files? 
(latest GWT 2.7 version)
---
[ERROR] Only either css files or gss files are supported on one 
interface 
---

Why isn't it allowed to combine them ?
Combining it makes it much more friendly/easy to switch to GSS.
In my case it's a blocker to move to GSS. In my general components, that 
have their own resource bundle, I use adapter/empty css files that only 
contains the class names without any css rules. They are very handy to use 
and overcomes to having to add all class names to a css file.
They are empty so I don't see any problem that GSS can't process them.
Currently it's impossible to rename all the css files in general components 
to gss.

How to solve this ? Can't GSS not process CSS files as welll?

GSS: Variable inside CSS 3 calc procudes compile error

[Christian Walczyk]

Hello,

I'm using GWT 2.7 with the experimental GSS support turned on and most of 
the GSS features are working fine as expected. One thing which is not 
working for me is the CSS3 calc() together with variables. This gss source 
code part of my UiBinder file leads to a compile error with a 
GssParserException:


@def AAA 140px;

.content{
   height: calc(100% - AAA); 
}


Am I wrong with something?

Thanks.

Why do you write: style.@com.ruchi.bundle.client.Button::gwtbutton()()  ?? 

Your style variable is not of type Button, its a MyCssResource instance. 
Also the gwtbutton() method is probably not defined on your Button class 
and I think Eclipse should have marked that red (if you use the Google 
Eclipse Plugin).

You always have to use ()(). The first parenthesis contain the parameter 
signature while the second parenthesis contain the actual parameters. So if 
you have a method that takes a String parameter it would look like 
myMethod(Ljava/lang/String;)(myStringInstance). Read: 
http://www.gwtproject.org/doc/latest/DevGuideCodingBasicsJSNI.html

No. If you fix the Button thing I mentioned above you are already done.

Re: JSNI - how to reference a CSS client bundle?

Your "lib" variable is of type Resource but your gwtbutton() method is 
defined on MyCssResource. So you first have to call Resource.button() to 
get a MyCssResource and then call MyCssResource.gwtbutton().

Re: change CSS style of a single GWT widget

Because .gwt-TabLayoutPanel is not assigned to a child element of the 
element that has .myPanel assigned.

To check if multiple classes are assigned to the same element you have to 
remove the whitespace:

.myPanel.gwt-TabLayoutPanel .gwt-TabLayoutPanelContentContainer

Re: change CSS style of a single GWT widget

[Magnus]

Ok, I added a class name:

myTabLayoutPanel.addStyleName ("myPanel");


This produces the following HTML code:




Since I only want to style the content, I need to include 
.gwt-TabLayoutPanelContentContainer.

This one had no effect (why?):

.myPanel .gwt-TabLayoutPanel .gwt-TabLayoutPanelContentContainer


The only combination that worked for me was:

.myPanel .gwt-TabLayoutPanelContentContainer


Thanks
Magnus
