Change Stylesheet depending on device
Hey, it ist possible to change the css in GWT depending which device the User has? f.e. if the User call my WebApp with chrome I want to load myWebapp.css when the User load from a website I want to remove myWebapp.css and replace it with myWebappMobile,css. I'm looking for something simular to replace-with /replace-with in gwt.xml but I found this only for java classes. Does any one know a good solution for this ?

Re: GWT Cell tree refresh issue

MyNode.java This is a bean class that holds the data to display in the tree MyTreeView.java Here we build the tree and add the nodes to the tree. First time when I build the treeView with data it invokes buildTree() where I call CellTree() constructor with MyViewModel as parameter, that will invoke getNodeInfo() (overidden method) of MyViewModel class. This is how I could able to see the data in tree view. But when I try to add a new child to the tree, I call the same flow, but it doesnot invoke the getNodeInfo() of the MyViewModel class. Hence I dont see the updated tree. What do you mean by I call the same flow ? To update your tree, the NodeInfo has to call updateRowData/updateRowCount on the HasData passed to it. With a DefaultNodeInfo, you'd have to call updateRowData/updateRowCount of your AbstractDataProvider. With a ListDataProvider, this is done by modifying the list returned by the ListDataProvider's getList(); in case you modified the underlying list (in your case, not possible as you copy it into a new ArrayList) then you can call the ListDataProvider's refresh(), but as the javadoc tells you, you should prefer getList(). Think about a CellTree as if it was made of nested CellLists (that's more or less the case), each one's data being provided by the NodeInfo. You have to work with your tree of NodeInfo nodes or their ListDataProvider to update the tree. The way I do it is I keep a MapMyNode, ListDataProviderMyNode, and update the tree through the MyViewModel with methods like add(MyNode parent, MyNode child). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GeoChart not working in GWT application
I don't know how to fix the problem you're facing, but if I understand
correctly, you're wrapping the JS API. Have you considered using any of the
two already available wrappers for GWT?:
https://code.google.com/p/gwt-google-apis/wiki/VisualizationGettingStarted
(official
project from google)
https://code.google.com/p/gwt-charts/ (unofficial but apparently more
up-to-date with the JS API)
I use the first one successfully with only a few JSNI snippets of code.
I've never used the GeoChart, but both wrappers above claim to support it.

Hi all,
I'm working at an application made with gwt.. and I just integrated some
charts with GWT Visualization api from google.
Most of the charts have wrappers to implement those available in JS also
in GWT.
So, I made a wrapper for GeoChart chart.. and I got an error every time I
try to instantiate this chart. Rest of the charts work perfectly.
This is the error:

I've debugged the application line by line and still can't figure what's
the problem. In my chart wrapper I have the method createJso() implemented
as a native method. In the superclasses of my class respectively, CoreChart
and Visualization, I also have the method, only difference is that in
Visualization superclass the createJso method is declarated as abstract.
I really can't seem to find what's the problem. For the other charts
everything works well.
This is the part of the code that generates the error.
public Visualization() {
Element div = DOM.createDiv();
--jso = createJso(div); --
setElement(div);
setStyleName(gwt-viz-container);
}
public Visualization(AbstractDataTable data, OptionsType options) {
this();
this.options = options;
this.dataTable = data;
}
Thank you,
Marian

Re: GWT In Eclipse Debug Mode All Of A Sudden is Super Slow
Also, for the beginners, you might have to set the log level to 'info' in the run configurations of the GWT.

Call REST service from GWT App's client side
Hi everyone! Please, help me figure out how can I manage to call the
external REST service from GWT application's client code.
I've heard, that GWT has a RequstBuilder class in order to do such things,
but suddenly I figured out that this is a quite ancient approach to
implement. Hence, the following code won't work:
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
http://localhost:1/hello;);
builder.setHeader(content-type, text/html;charset=windows-1251);
builder.setHeader(Access-Control-Allow-Origin, *);//*result doesn
not depend on this line of code*
try {
Request response = builder.sendRequest(, new
RequestCallback() {
@Override
public void onResponseReceived(Request request, Response
response) {
answerFromRest.setText(request.toString() + \n);
answerFromRest.setText(response.toString() + \n);
int statusCode = response.getStatusCode();
if(statusCode == Response.SC_OK) {
String responseBody = response.getText();
answerFromRest.setText(The result is +
responseBody);
} else {
answerFromRest.setText(There was an error +
statusCode + = + response.getText());
}
}
@Override
public void onError(Request request, Throwable exception) {
//error actually sending the request, never got sent
}
});
} catch (RequestException e) {
e.printStackTrace(); //To change body of catch statement use
File | Settings | File Templates.
}
*
*
*
*
*statusCode *always equals 0 though when I access my depolyed REST through
a WebBrowser, I get the result. This makes me feel like there is really no
more support for that code in GWT...
So, the question is - is there the other (working) way to call REST writing
code in java ( I mean w/o using JSNI code to do that ).
Any way, whatever approach is ( if it exists in GWT's nowadays ), can you
please provide either _code_ or _decent link with tutor or smth like that_ ?
Thank you very much, for the time spent on my subject

Re: [gwt-contrib] gwt.junit.testcase.includes broken?
