Select(listbox) box with custom selection image arrow in GWT 2.0
Hi, Is it possible to create select(list) box with custom image for the selection arrow? the standard gwt list box does not use any resources so i think it can't be customized for that, so i need to create my own widget?

Hi, i have image 1x600px that i need to "repeat" as panel background. I am using CssResource and Client Bundle but i do not know how to do it or i am missing somthing. I use @ImageOptions (repeatStyle=RepeatStyle.Horizontal), but it seems it is not working? I am using gwt 2.0 MS2. The image is just rendered once(not repeated in order to create background). Pleas could you give me some example how to do this with CssResource and ClientBundle.

Re: GWT + light streamer = integration problems
Hi, all. I resolved my PushPage is not defined error, just with adding $wnd like this var pushpage = new $wnd.PushPage() but i'm getting Error: Permission denied to get property Window.PushPage because of the same origin policy.

GWT + light streamer = integration problems
Hi, all i need to integrate gwt with lightstreamer. I have some
problems connected with how to call js in gwt. I have been using
native methods before but this time something is going wrong and i
can't understand what.
So here is every thing explained in brief:
Lightstreamer has 2 .js lib files. I include them in my host page and
they are loaded successfully.
I wrote native method that calls some js code that subscribes for ls
feeder:
private static native void init(ListGrid grid, ListGridRecord record,
int recordIndex) /*-{
try {
var page = new PushPage();
page.context.setDomain("localhost");
page.onEngineCreation = function(engine) {
engine.connection.setLSHost("localhost");
engine.connection.setLSPort();
engine.connection.setAdapterName("HELLOWORLD");
engine.changeStatus("STREAMING");
}
page.bind();
page.createEngine("HelloWorldApp", "LS/",
"SHARE_SESSION");
var schema = new Array("message","timestamp");
var group = new Array("greetings");
var nvt = new NonVisualTable(group,schema,"MERGE");
nvt.setSnapshotRequired(true);
var c = 1;
nvt.onItemUpdate = function(item, itemUpdate, itemName)
{
if (itemUpdate.isValueChanged("message")) {
var msg = itemUpdate.getNewValue("message");
var ts = itemUpdate.getNewValue("timestamp");
if (c == 1) {
alert(msg + " " + ts);
c+= 1;
}
record.setAttribute("message", msg);
record.setAttribute("timestamp", ts);
grid.refreshRow(recordIndex);
}
}
page.addTable(nvt,"hellotable");
} catch(error) {
alert(error);
}
}-*/;'
The same code executed in html page is working, but if i call it from
onModuleLoad()
the alert(error) shows me an error: PushPage is not defined and
PushPage is defined in the external lightstreamer js lib files, which
i included in my host page.
Here is working code in html page:
loading...
loading...
Updates:
var page = new PushPage();
page.context.setDomain("localhost");
page.onEngineCreation = function(engine) {
engine.connection.setLSHost("localhost");
engine.connection.setLSPort();
engine.connection.setAdapterName("HELLOWORLD");
engine.changeStatus("STREAMING");
}
page.bind();
page.createEngine("HelloWorldApp", "LS/",
"SHARE_SESSION");
var schema = new Array("message","timestamp");
var group = new Array("greetings");
var nvt = new NonVisualTable(group,schema,"MERGE");
nvt.setSnapshotRequired(true);
nvt.onItemUpdate = function(item, itemUpdate, itemName) {
var updateText = "updating item " + itemName + ". ";
if (itemUpdate.isValueChanged("message")) {
updateText += "New value for last_price: " +
itemUpdate.getNewValue
("message");
}
document.getElementById("container").innerHTML += updateText +
"
";
}
page.addTable(nvt,"hellotable");
In the gwt application i want to update some grid row and in the html
application i update some div as you can see.
So the main problem is why PushPage is not defined?

GWT + Base64 encode Java object on server and decode on client
Hi, dear members, Is it possible to base64 encode some java object( DTO) on the server and send it to gwt client side, where i need to restore (decode it to the same DTO object)? Here is why i need this: I have a servlet, that sends sends messages to active mq queue. I have gwt client that uses active mq ajax to update some table with the messages. Active mq needs the messages to be strings, and i manually create object->string but it is annoying and not flexible. So what i need to encode my objects in the servlet to base64 strings and send them to the queue and when the gwt receives the base64 string it just must decode it to the original DTO object. Is this possible and how to do it? Regards. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Event handler for model ?
Here you are some simple example, witch is not the best example but
would point you:
public interface MyHandler {
public void handle(T t);
}
public class ArrivalData {
private Date date;
private boolean processing = false;
private List> dateHandlers = new
ArrayList();
public void addHandler(MyHandler h) {
dateHandlers.add(h);
}
public Date getDate() {
return date;
}
public void setDate(Date date) {
this.date = date;
for(MyHandler h : dateHandlers) {
h.handle(date);
}
}
}
public class CustomObject implements MyHandler {
@Override
public void handle(Date date) {
// receive data from setDate(..);
// handle it in some way
}
}

Re: Accessing a DB
Every thing witch is in your server package is on the server, so no one could access your private data. It is like in hibernate, that has hibernate config file where the user and pass are stored. This config file is on the server and no one has access to it. Sean wrote: > In regards to using RPC's to access a database, I am worried about > security.

GWT + hosted mode + jboss
Hi, all, I dig the web, but i could not find how to run hosted mode with external jboss. Here is what i do: 1) Create web project with google plugin for eclipse, that creates me "hello world" project with gwt. 2) test it within the internal server and it works. 3) Add new server runtime jboss 4.2. 4) Change the project facets -> runtimes check jboss. 5) run configurations -> set the port 8080 and uncheck the "use default server" checkbox 6) Start the jboss from eclipse(view servers) 6) run the application with the google plugin When the hosted browser is displayed it says that it could not find the resource on the server. So my question is how to deploy on the server, if i have to do it every time when i change something this host mode is useless with external server. I also added -noserver, but the application is not deployed on the jboss so the effect is the same. How to manage this. I look all over the net but i could not find any complete example how to do this, every one just says use -noserver, but that does not solve the problem. Pls help me i am new with gwt.
