Re: Help: GWT Celltable Record (Specific Record Mouseover) ToolTip !!!
Hi,
i've had the same problem, many thanks to Jens and Rajeshwar for the
solution!
I've extended Column and TextColumn:
public abstract class TooltipColumnT, C extends ColumnT, C{
private final CellC cell;
public TooltipColumn(CellC cell) {
super(cell);
this.cell = cell;
}
public abstract SafeHtml getTooltipValue(T object);
@Override
public void render(Context context, T object, SafeHtmlBuilder sb) {
SafeHtmlBuilder mysb = new SafeHtmlBuilder();
cell.render(context, getValue(object), mysb);
mysb.appendHtmlConstant(span);
mysb.append(getTooltipValue(object));
mysb.appendHtmlConstant(/span);
sb.append(mysb.toSafeHtml());
}
}
public abstract class TooltipTextColumnT extends TooltipColumnT,
String {
/**
* Construct a new TextColumn.
*/
public TooltipTextColumn() {
super(new TextCell());
}
}
CSS:
.CssCellTableCell span {
display:none
}
.CssCellTableCell:hover span {
border:1px solid #e6e3e5;
DISPLAY: block;
Z-INDEX: 1000;
PADDING: 0px 10px 0px 10px;
POSITION:absolute;
float:left;
background:#d1;
TEXT-DECORATION: none
}
Add a Column:
TooltipTextColumnTodos aTextColumn = new
TooltipTextColumnTodos() {
@Override
public String getValue(Todos object) {
return object.getText();
}
@Override
public SafeHtml getTooltipValue(Todos object) {
return new
SafeHtmlBuilder().appendEscaped(object.getText()).toSafeHtml();
}
};
cellTable.addColumn(aTextColumn, Text);

Problem using classes from external modules
Hi I am trying to get my GWT application to work with an existing project consisting of several maven modules. Currently I'm struggling trying to use an enum from one of the existing maven modules, in my GWT client-side code. The way I'm tying to do it is by creating an extra GWT module where the enum is located. EXISTING MAVEN MODULE: *ExtraModule* src/com/app/extra/ExtraModule.gwt.xml src/com/app/extra/data/MyEnum.java module rename-to=ExtraModule source path=data include name=MyEnum.java / /source /module NEW GWT MAVEN MODULE: *MainModule* src/com/app/main/MainModule.gwt.xml src/com/app/main/client/XAdmin.java module rename-to='MainModule' inherits name=ExtraModule / entry-point class='com.app.main.client.XAdmin' / /module I managed to make the source from ExtraModule available in MainModule by using the Build Helper maven-plugin: from my pom.xml plugin groupIdorg.codehaus.mojo/groupId artifactIdbuild-helper-maven-plugin/artifactId version1.7/version executions execution idadd-source/id phasegenerate-sources/phase goals goaladd-source/goal /goals configuration sources source/path/to/project/src/com/app/extra//source /sources /configuration /execution /executions /plugin This seems to work just fine, as ExtraModule was found and skipped (as there is no entry-point). The enum, MyEnum.java, however, is nowhere to be found. What am I doing wrong here?

RequestFactory: Child proxy is null on client side
Hi there
I'm having some difficulties using RequestFactory (and Objectify). I have
two entities Item and Payload, and corresponding proxies ItemProxy and
PayloadProxy (*#1*). If I call ItemRequestContext.saveAndReturn() on the
clientside (*#3*) a simple println in my ItemDao shows the Payload as having
an id (*#2*). But when the Response reaches the client side, the Payload is
just null.
Is there some obvious reason why the Payload doesn't make it to the client
side, given the code snippets below?
*CODE SNIPPET #1*
@Entity
public class Item extends DatastoreObjectGenerated {
private KeyPayload payloadKey;
@Transient
private Payload load;
public Item() {
}
public void setPayload(Payload load) {
this.load = load;
}
public Payload getPayload() {
return this.load;
}
}
@ProxyFor(value = Item.class, locator = ObjectifyGeneratedLocator.class)
public interface ItemProxy extends DatastoreObjectGeneratedProxy {
public void setPayload(PayloadProxy load);
public PayloadProxy getPayload();
}
@Entity
public class Payload extends DatastoreObject {
public Payload() {
}
}
@ProxyFor(value = Payload.class, locator = ObjectifyLocator.class)
public interface PayloadProxy extends DatastoreObjectProxy {
}
*CODE SNIPPET #2*
public class ItemDao extends ObjectifyDaoItem {
public Item saveAndReturn(Item item) {
...
Item it = getItem(item.getId());
System.out.println(Payload ID: + it.getPayload().getId());
return tr;
}
}
// PRINTS
// Payload ID: 18
*CODE SNIPPET #3*
RequestItemProxy req = this.itemRequestContext.saveAndReturn(item);
req.fire(new ReceiverItemProxy() {
@Override
public void onSuccess(ItemProxy response) {
System.out.println(Payload ID: + response.getPayload());
}
});
// PRINTS
// Payload ID: null

Re: Create Canvas widget from CanvasElement
constructor protected CanvasElement() It means that you can derive your own class for CanvasElement. Adding it in a GWT container works for me. I agree with you : I don't understand why there is also a Canvas class, and why the constructor is private ? Canvas is a Widget (derives from FocusWidget). CanvasElement is just a wrapper around the DOM element canvas (derives com.google.gwt.dom.client.Element). To be precise, CanvasElement is not even a wrapper it is a JavaScriptObject which means that you can not create it in Java (by calling a constructor). Instead, we have to use Document.get().createCanvasElement() which does its work by calling a JSNI method. I want the widget so that I can do all the event handling in Java (FocusWidget implements tons of Has*Handlers interfaces). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Create Canvas widget from CanvasElement
I want to wrap a CanvasElement (canvas in HTML) in an Canvas widget.
Many widgets (e.g. Label) have a static method SomeWidget.wrap(Element) for
wrapping an existing DOM element.
I imagine Canvas does not feature such a method because not all browser
support canvas and therefore the user should be forced to go
through createIfSupported().
Unfortunately the constructor in Canvas is private, which means that Canvas
can not be subclassed. (There isn't any constructor available in the derived
class.)
Code snippets of createIfSupported and the constructor in Canvas:
public static Canvas createIfSupported() {
// check if canvas is supported; if it is not supported: return null
return new Canvas(element);
}
private Canvas(CanvasElement element) {
setElement(element);
}
I ended up copying the Canvas class and making the constructor public.
Is there a better way to do this?
If not, what is the reasoning behind it (besides that it might not be
supported)?
I am using version 2.4.0.rc1.
Thanks,
Julian

ProxyAutoBean server-side cache
Hi, it appears that for every EntityProxy instance that a client requests via RequestFactory, a ProxyAutoBean object is created on the server. Is this correct? If so, what is the lifecycle of the ProxyAutoBean, at what point does it get deleted? I can see (in jvisualvm) that it lives in a WeakMapping, so maybe it is intended to be removed when the GC needs the memory it occupies. However, a few initial tests seem to show that the ProxyAutoBeans survive low memory conditions and keep accumulating. Am I doing something wrong or is this expected behaviour? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

requestFactory: NPE while traversing local read-only proxies
Hi, I've recently set up remote logging which now gives me more visibility on client-side bugs. One problem that I've discovered this way, but never ran into myself, are spurious errors like the ones attached below. As you can see, the stack trace isn't always identical but it usually looks like an NPE somewhere in AbstractRequestContext.doFire. Now, my understanding is that this might have to do with the requestContext looking for any changes to local proxies. What baffles me, though, is that for the specific RequestContext involved in these errors the entities are never edited - the corresponding proxy class doesn't even have setters, and edit() is never called. The calls in question here are purely for getting data from the server (specifically, a total entity count and one result page, for populating a page of a CellTable). That's why I'm not sure why getVersion would even have to be called on the client side at all. I've double-checked that all arguments to the count and list operations are non-null. So far I don't know how to reproduce this error or else I would try to condense it into a test case. I'm hoping you might have an idea of where I could start looking? Also, is there any way I can make the stack traces more informative or enable other relevant debug output?

Re: CellTable: Unable to combine CSS-selectors
Thank you John, Brian and zakness. All of you were spot on!
I was confusing descendant selectors and multiple selectors. I guess the
reason I was having such a hard time figuring out this one was because the
parent TR had many of the same styles applied. This gave the illusion that
the way I was trying to use the selectors was working in some cases but not
in others.
Removing the space and thus turning it into a multi class selector solved
the problem:
.cellTableFirstColumn.cellTableKeyboardSelectedRowCell {
background-color: fuchsia !important;
}

CellTable: Prevent styling of selected rows
Hi awesome people
I'm trying to control which of the columns in a CellTable will trigger a
SelectionChangeEvent by implementing CellPreviewEvent.Handler.
The problem is that even if I cancel the SelectionChangeEvent, the
CSS-styles for *selected rows* are still applied (
.cellTableKeyboardSelectedRow), which means it looks like the row i being
selected to the user. Is there any way to change this behavior, or is there
some other way of controlling which columns trigger selection? I have a
CellTable with several button columns and several text columns, and I want
to disable selection on some of them.
The code below creates a CellTable with to columns. When you click on one of
the columns an alert-box pops up, and when you click other the nothing pops
up, but the row looks like it's being selected.
CellTableMyProxy cellTable = new CellTableMyProxy(50);
final NoSelectionModelMyProxy selectionModel = new
NoSelectionModelMyProxy();
selectionModel.addSelectionChangeHandler(new SelectionChangeEvent.Handler()
{
public void onSelectionChange(SelectionChangeEvent event) {
Object selected = selectionModel.getLastSelectedObject();
if (selected != null) {
Window.alert(Selected something);
}
}
});
CellPreviewEvent.HandlerMyProxy selectionEventManager = new
CellPreviewEvent.HandlerMyProxy() {
@Override
public void onCellPreview(CellPreviewEventMyProxy event) {
if (event.getColumn() == 0) {
event.setCanceled(true);
}
else {
// Handle default selection.
NativeEvent nativeEvent = event.getNativeEvent();
String type = nativeEvent.getType();
if (click.equals(type)) {
if (nativeEvent.getCtrlKey() || nativeEvent.getMetaKey()) {
// Toggle selection on ctrl+click.
selectionModel.setSelected(event.getValue(),
!selectionModel.isSelected(event.getValue()));
}
else {
// Select on click.
selectionModel.setSelected(event.getValue(), true);
}
}
else if (keyup.equals(type)) {
// Toggle selection on space.
int keyCode = nativeEvent.getKeyCode();
if (keyCode == 32) {
selectionModel.setSelected(event.getValue(),
!selectionModel.isSelected(event.getValue()));
}
}
}
}
};
cellTable.addColumn(new TextColumnMyProxy() {
@Override
public String getValue(MyProxy object) {
return object.getTitle();
}
});
cellTable.addColumn(new TextColumnMyProxy() {
@Override
public String getValue(MyProxy object) {
return object.getId();
}
});

CellTable: Unable to combine CSS-selectors
Hi there
I'm trying to combine the cellTableFirstColumn and
cellTableKeyboardSelectedRowCell
selectors to set background-color of the first cell in the selected row to a
lovely pink.
I have the following in my *CellTablePatch.css*
.cellTableFirstColumn .cellTableKeyboardSelectedRowCell {
background-color: fuchsia !important;
}
But for some this style isn't applied. Firebug tells me both of the styles
are applied to the first cell in the selected row, but no pink shows up.
Combining two other selectors in the same way, e.g. cellTableEvenRow and
cellTableFirstColumn works just fine.
Any clues to what I'm doing wrong here?

Get JSON content from GWT
Hi all !!
im trying to get the content from a json service like yahoo, but I
never get the result correctly:
this is my code:
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
http://api.search.yahoo.com/ImageSearchService/V1/imageSearch?
appid=YahooDemoquery=potatoresults=2output=json);
Request request = builder.sendRequest(null, new
RequestCallback() {
public void onError(Request request, Throwable exception) {
GWT.log(Couldn't retrieve JSON);
}
public void onResponseReceived(Request request, Response
response) {
GWT.log(Response text: +response.getText());
if (200 == response.getStatusCode()) {
JSONValue value = JSONParser.parse(response.getText());
JSONObject obj = value.isObject();
JSONArray jarray =
obj.get(jsonResponse).isObject().get(results).isArray();
for(int i=0; i=jarray.size()-1; i++){
JSONObject arrayObjs = jarray.get(i).isObject();
String name =
arrayObjs.get(location).isObject().get(name).isString().stringValue();
GWT.log(name);
//Implement the rest of your logic.
}
} else {
GWT.log(Couldn't retrieve JSON CODE 200( +
response.getStatusText() +response.getHeadersAsString()
+ ));
}
}
});
Every time the response.getText() is empty... How can i get the
content from this json service??
im trying with the google example with json tree, but when i change
the js for the real url in yahoo (not in local result .js file) the
result is empty all time!!
Thanks for ur help !!!

Re: RC2 and Eclipse Plugin
I also have no urls in the developer mode view. Running Eclipse 3.5, OS X Snow Leopard, gwt 2.0 using gwt-maven-plugin 1.2-SNAPSHOT But I can access the developer server by entering the url in the browser manually: http://localhost:/my.web.App/index.html?gwt.codesvr=localhost:9997 Interesting that I get a dialog saying that my module may need to recompiled when I use the url: http://localhost:/my.web.App/index.html Changing the working directory to point to the war folder didn't help. Also.. when using developer mode it runs extremely slowly in both safari and firefox. cpu at about 70% and network over local loop at 2.3MB / sec -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Deferred binding for mobile browser support
Thanks Sumit as always -- can I check why the fall-through class exists at all? It seems a little redundant for something to replace itself! :) I know that's what the docs say ... but why I wonder? On Aug 10, 11:53 pm, Sumit Chandel sumitchan...@google.com wrote: Hi Michael, If you could elaborate a little more on which part of deferred binding you're not sure about, that would help pinpoint the problem you're having and setup deferred binding code for your mobile browser target. In general, however, the way deferred binding works is by defining the rules for the deferred binding using replacement (see doc link below), creating the default and the mobile classes that should be used for the desktop browser and mobile browser versions of your widget, respectively, and then creating your widget via the GWT.create(MyWidget.class) call to have the compiler create bindings for the mobile target. Deferred Binding using Replacement:http://code.google.com/webtoolkit/doc/1.6/DevGuideCodingBasics.html#D... For an example, check out the inner workings of the PopupPanel widget. You'll notice that the PopupImpl instance belonging to the PopupPanel class is created using the GWT.create(PopupImpl.class) call. Looking at the deferred binding rules for the PopupPanel in the Popup.gwt.xml file (contained in the gwt-user.jar), you'll see that the following rules are defined: !-- Fall through to this rule is the browser isn't IE or Mozilla -- replace-with class=com.google.gwt.user.client.ui.impl.PopupImpl when-type-is class=com.google.gwt.user.client.ui.impl.PopupImpl/ /replace-with !-- Mozilla needs a different implementation due to issue #410 -- replace-with class=com.google.gwt.user.client.ui.impl.PopupImplMozilla when-type-is class=com.google.gwt.user.client.ui.impl.PopupImpl/ any when-property-is name=user.agent value=gecko/ when-property-is name=user.agent value=gecko1_8/ /any /replace-with You could essentially follow the same pattern for the mobile version of MyWidget.class, perhaps creating a MyWidget.gwt.xml file to contain the deferred binding rules. Hope that helps, -Sumit Chandel On Tue, Aug 4, 2009 at 3:38 AM, grue michael.gruetz...@googlemail.comwrote: Hi, I have to add a mobile-optimized version to an existing gwt application. After digging through the docs I found out that deferred binding is the technology of chioce. I believe I understand how it basically works but how do I use it in that specific use case? The mobile UI of our application differs a lot from the standard version so I need seperate stylesheets, and seperate GWT controls (we use composites a lot). Since the basic layout of our application is done in the .html file I would also need a separate html file. Now the question is: how do I do that? Are there any best practices? I'd really appreciate any hint. Best regards, Michael --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GALGWT, Eclipse 3.5 / Galileo, and GWT 1.7 -- how to add this or any other GWT library to projects?
Thanks Philip! I'll give this a try -- it worked fine in hosted mode I assume.

Getting User Credential from IE
I realized that when we use our corporate Seibel page using IE, it knows the Logon User Name. I like IE to pass GWT the User Name that is already authenticated into Windows. I'm new to front end programming, can someone give me some concept that I need to go and figure this out.
