Re: GWT Celltable How to make Non-Editable cell in Editable column
Thanks Ozgur.
public void render(com.google.gwt.cell.client.Cell.Context context,
String value, SafeHtmlBuilder sb) {
if(context.getColumn()==2 context.getIndex()==0 ){
sb.appendHtmlConstant(div
contentEditable='false'
unselectable='true'/div); // This non-editable cell
// This will work in mozila firefox ? div
contentEditable='false' unselectable='true'/div
}else{
super.render(context, value, sb);
}
}
It works fine as per my use case. :)
Now problem is when I am performing pagination then next N-1 page's
2nd_column of 1st cell is editable :|
How can I do it as non-editable on pagination ?

Hi,
You can create your own cell, in the render method:
public class MyCustomeCell extends EditTextCell {
...
public void render(Context context, String data, SafeHtmlBuilder sb)
{
if(context.getIndex()==0)
// render your own cell, a div or something... ex: divdata/
div
else
super.render(context,data, sb);
}
...

All cells in testColumn are editable.
I want 1st cell of column such way that 1st cell of column should be
Non-Editable.

Re: problems with loading stuff/bootstrapping onModuleLoad triggered by an event
ok, thx thomas it begins to become clearer,
my code attached don't use scheduler, thats right. meanwhile (thx to you
thomas) i played with Scheduler and Timer. The current code looks like:
public void start() {
Timer timer = new Timer() {
@Override
public void run() {
if (ttReady auReady) {
continueStart();
this.cancel();
}
else {
System.out.println(waiting: + ttReady + +
auReady);
}
}
};
timer.scheduleRepeating(1000);
}
but the feeling about this code is not better than the feeling with my
infinite loop. i think the problem is, that i don't really understand the
backgrounds - especially the scheduler. could you please show me some
sample code for my special problem (how should start() look like?) or give
some reference to docs explaining the scheduler/the model behind it?

Gwt-App totally blocks Browser-UI
At the start of my App the Browser has to load some stuff and create some data objects (Trees). The Problem is, that this blocks the the whole browser (no tab switching no reaction on user interactions, even my animated loading.gif is not loaded/animated). In swing applications the is a SwingWorker to keep the ui running - for example to display a progress bar. But how to achieve this with GWT? My guess is to use Scheduler some how?!

Re: Gwt-App totally blocks Browser-UI
Javascript is single threaded, so you shouldn't do too much in one go. You can use Scheduler.get().scheduleIncremental(repeatingCmd) to do some work in pieces. If the problem is that it's slow while dealing with large RPC messages, then you may need smaller messages.

Re: problems with loading stuff/bootstrapping onModuleLoad triggered by an event
i found a bit of info about scheduler
herehttp://stackoverflow.com/questions/5131086/using-the-gwt-scheduler.
now i got:
private boolean tryToContinue() {
if (ttReady auReady) {
continueStart();
return false;
} else
return true;
}
public void start() {
Scheduler.get().scheduleEntry(new RepeatingCommand() {
@Override
public boolean execute() {
return tryToContinue();
}
});
i used scheduleEntry because of Javadoc: This type of command is
appropriate for instrumentation or code that needs to know when something
happens.
But i am unsure about my implementation/ my understanding about scheduler -
is the code above correct?

Re: problems with loading stuff/bootstrapping onModuleLoad triggered by an event
Using SimpleEventBus the following does not behave like you expect:
eventBus.addHandler(FirstEvent.TYPE, new FirstHandler() {
void onFirstEvent(FirstEvent e) {
//will be enqueued to be added. So handler is not fully registered
eventBus.addHandler(SecondEvent.TYPE, new SecondHandler() {
void onSecondEvent(SecondEvent e) {
sysout(second event)
}
}
//wont trigger handler from above
eventBus.fire(new SecondEvent());
sysout(first event done);
}
});
The output would be first event done and you wont see second event on
the console. As Thomas said handlers that you add to the event bus while an
event is actually dispatched (in this case FirstEvent) will cause the
SimpleEventBus to put the new handler into a queue. After all events are
dispatched the contents of this queue is added to the list of known
handlers ready to be executed. But as all events are already dispatched
these new handlers wont get executed.
And thats exactly what happens with your original code. Once your
DataReceiver has finished loading your data you fire an event
OnSometimeEvent. The handler of this event calls continueStart() which in
turn adds a handler to the event bus via historyHandler.register(...) and
then fires a second event via historyHandler.handleCurrentHistory().
Because you register the history handler while your OnSometimeEvent gets
dispatched this handler will be stored in a queue in SimpleEventBus. Then
the second event will be dispatched (fired by
historyHandler.handleCurrentHistory()) and after this event has been
executed the handler in the queue will be added to the list of known
handlers.
To solve this you either have to refactor your code in a way that all
handlers are registered to the event bus before OnSometimeEvent is fired or
you have to break your code execution flow by taking the continueStart()
method and defer it until OnSometimeEvent has been dispatched.
So:
public void start() {
if(dataReady) {
Scheduler.get().scheduleFinally(
//
continueStart();
);
} else { //wait }
}
should do the trick. If scheduleFinally does not work try scheduleDeferred
which executes the code even later. If you want to understand the Scheduler
class you should read something about the browser event loop.

Re: Gwt-App totally blocks Browser-UI
thx, are there any examples how to use scheduleIncremental? I don't want/can't to split the work that has to be done manually but i want to give the browser a chance to do other stuff - is it possible to interrupt a task for some time? In my case the main work has two parts: loading of data (one ArrayList containing the tree structure) and creating a tree widget with it. but splitting the work in this two parts wouldn't be enough - the second part alone could block a browser on a slow machine for up to 10seconds - very bad.

The first 3 methods you already have, the last one too, just missing that
damn Scheduler bit; i.e. 5 damn lines.

Need to store a hashmap in memory to keep the counters for different user
Hi, I am working on storing different user counters in memory at application level (not database) and to have counters to atmost 3. I developed this code using a singleton class with hashmap to store a key value pair of user id and and it's counter and time. After initial, i was using this singleton class on client side, it worked fine for counters but when browser was refreshed, a new singleton object was created. I searched, and come to know that for security reason, javascript don't use shared objects, so i moved it to rpc call and make it server side object to overcome it, but when i tested it again, on refresh new object is created and data lost. I also tested the static hashmap to hold the data for application scope, but it has almost the same behavior, once refreshed the browser, its reset and old data is lost in it. It little different behavior from normal java web apps where we follow this approach. Does any one know how can i keep object at application scope in gwt ? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Exception thrown by FlexTable
Hello. I am fairly new to GWT but really enjoying its use. I have the
following dilemma.
I build a FlexTable using and define the contents of its first row as
follows:
fts.setText(0,0,Passenger ID);
fts.setText(0, 1, Source Floor);
fts.setText(0,2, Destination Floor);
update(index);
The update index is responsible for finishing the initialization.
Inside it has a for loop of the following form:
for(int i = 1; i = data.passenger_destinations.size(); ++i){
fts.setText(i,0,Passenger +
i);
fts.setText(i,1,
Integer.toString(data.passenger_origins.get(i-1)+1));
fts.getCellFormatter().setHorizontalAlignment(i,
1,HasHorizontalAlignment.ALIGN_CENTER);
fts.setText(i,2,
Integer.toString(data.passenger_destinations.get(i-1)+1));
fts.getCellFormatter().setHorizontalAlignment(i,
2,HasHorizontalAlignment.ALIGN_CENTER);
}
That is about all the code dealing with the FlexTable. However, when
the code is run, at some point during its execution I get the
following exception:
21:22:34.733 [ERROR] [visualizer] Uncaught exception escaped

'@com.google.gwt.user.client.ui.HTMLTable::getDOMRowCount(Lcom/google/
gwt/user/client/Element;)': JS value of type null, expected int
That seems clear enough, but when I look at the stack trace, I see
that it happens on the line with the arrow above, and is thrown by the
FlexTable when it tries to get the row count. I am wondering if anyone
knows what is going on, or how to proceed in investigating the matter.

Re: problems with loading stuff/bootstrapping onModuleLoad triggered by an event
At the moment i read your last post/ understood the problem i knew that you
tried it several times - i saw all your vehement efforts to get it into my
brain (but some times brains don't want to see :-) ).
i just refactored my code - in fact i haven't changed much (i already had
some scheduler stuff in my code). Because all my tasks are done on
construction time (gin injected stuff, ApplicationManager registers himself
to onTaskDoneEvents in constructor) i got rid of the public start()
method. Now i only have a private start called in the way you suggested it:
...
@Override
public void onTopicTreeLoadedEvent(TopicTreeLoadedEvent event) {
ttReady = true;
start();
}
..
@Override
public void onAdminUnitsLoaded(AdminUnitsLoadedEvent event) {
auReady = true;
start();
}
...
private void start() {
if (ttReady auReady) {
Scheduler.get().scheduleFinally(new ScheduledCommand() {
@Override
public void execute() {
// set up activity managers
sidePanelAreaManager.setDisplay(contentArea.getWestSideArea());
breadCrumbAreaManager.setDisplay(contentArea.getBreadcrumArea());
contentMenuAreaManager.setDisplay(contentArea.getContentMenuArea());
contentAreaManager.setDisplay(contentArea.getContentArea());
// insert dynamic layout in static layout
staticView.getContentArea().setWidget(contentArea);
contentArea.setDefaultLayout();
historyHandler.register(placeController, eventBus,
startPlace);
historyHandler.handleCurrentHistory();
currentPlace = placeController.getWhere();
}
});
}
}

Re: Gwt-App totally blocks Browser-UI
Sounds like you're creating a tree with too many items. (How many?) Maybe you need some lazy creating of tree items. Paul On 02/11/11 11:27, tanteanni wrote: thx, are there any examples how to use scheduleIncremental? I don't want/can't to split the work that has to be done manually but i want to give the browser a chance to do other stuff - is it possible to interrupt a task for some time? In my case the main work has two parts: loading of data (one ArrayList containing the tree structure) and creating a tree widget with it. but splitting the work in this two parts wouldn't be enough - the second part alone could block a browser on a slow machine for up to 10seconds - very bad.

How to create a shared lib/utility class (client/server) ?
Hi,
I am trying to implement a small utility class / library that should be
useable on client side and on server side but has different implementation
on client and server.
For example I have a utility method that should make a http REST call. On
client side I should use RequestBuilder but on server side I have to use
java.net.* classes. How would I do that?
I tried the factory approach in combination with GWT.isScript() but this
didn't work because the GWT compiler still sees java.net.* classes and
wants to translate them:
public class SharedUtils {
private static final SharedUtilsFactory FACTORY = GWT.isScript() ?
new SharedUtilsFactoryJS() : new SharedUtilsFactoryVM();
public static RequestUtils requestUtils() {
return FACTORY.requestUtils();
}
}
Shouldn't this somehow be possible?
Thanks for help,
-- J.

RE: future of gwt who use gwt
I think even Google underestimates the power of GWT in such area as refactoring existing MFC C++/Java-Swing GUI clients into Web based. I rewrote MFC C++ client into GWT in a month. And most of the heavy business logic/calculations been just copy/paste from original C++. Can't imagine amount of work needed for such app if you use JavaScript -Sergey From: google-web-toolkit@googlegroups.com [mailto:google-web-toolkit@googlegroups.com] On Behalf Of David Chandler Sent: Tuesday, November 01, 2011 11:49 AM To: google-web-toolkit@googlegroups.com Subject: Re: future of gwt who use gwt Hi Warren, Glad you found my SenchaCon slides (thanks, Thomas--I should have posted them here, too). Let me put some context around fewer releases, less overhaul. Sencha's Darrell Meyer and Sven Brunken did a huge refactoring of Ext GWT last year to make it more compatible with mainline GWT. This was in part necessitated by all the major changes in GWT since 2.1: Cell widgets, Activities Places, RequestFactory / AutoBeans, etc. The GWT team has heard from the community quite a few times please slow down and just make it solid, and we're listening. As to the first point (Google is heavily invested), many of Google's largest projects are built with GWT, and it is widely used within the company. Because GWT is open source, the community will continue to benefit from all the work that Google does on GWT in support of our own projects. This remains one of the great benefits of using GWT. I apologize for the relative silence on this issue. In general, Google is very careful about making public commitments of any kind and rarely discusses future plans, in part because plans are subject to change. /dmc On Fri, Oct 28, 2011 at 11:32 PM, Warren Tang warren.c.t...@gmail.com wrote: The following line is also important: (GWT) Aiming for fewer releases, less overhaul.

Instead of :

I would like seeing something like :
${install}\plugins\com.google.gwt.eclipse.sdkbundke_2.4.0...\gwt-2.4.0
or
${workspace}\..\plugins
\com.google.gwt.eclipse.sdkbundke_2.4.0...\gwt-2.4.0

Opinions: GWT 2.x layout system - goal achieved?
Hi all, I am curious to hear people's opinions regarding the xxxLayoutPanel, i.e., GWT 2.x layout system. One of the first stated goals regarding the new system was: Perfectly predictable layout behavior. Precision layout should be possible. What has been your experience with this? Has that goal been achieved? I find it ironic that it now (post GWT 2.0) takes more tinkering with CSS to get it to look the same in all browsers. Was this the intended consequence? Curious as to what people's opinions are on this. Thanks, -Yaakov. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

We want you for GQuery
Dear community, The second release of GQuery is currently out. GQuery is now still much better than before and includes nice features like jquery Ajax syntax which enable to access most of the jQuery API. We are conviced that GQuery can, at certain level, make GWT developers' life easier. However, there is still lot of work to do and we have several ideas that we would like to implement towards the improvements of the quality and the usefulness of GQuery. Unfortunately, we believe that our current development team is not enough to deliver you these improvements in an acceptable time frame. That's why today we request for your help. If you have some free time and you would like to contribute to GQuery, just let us know. We have a few tasks that we can assign to you. Some task may take one hour, other tasks may take several days. They are related to the different aspect of a project. e.g. : - improve documentation and code examples - write new plugins or port existing jQuery plugins - improve testing of the library by implementing missing junit tests. - Enumerate and/or implement the remaining JQuery API methods to implement - Give some ideas/tips/snippets in order to improve/enhance/refactor the library - Reporting issues and bugs ;) If you are interested, please reply to this post or send me a mail ( julien.dramaix_at_gmail) Please indicate which tasks you will be interested to work in.

Re: future of gwt who use gwt
Thank you for sharing Thomas. Visualfox.me is a small design and strategy firm and we use GWT since few years now. Our use of GWT is unorthodox as we focus more on the visual/design aspect. Actually I think that one of the strength of GWT which is currently totally underused and underestimated. I was one of the participant at the developer sandbox at google IO 2010 and while I tried my best to highlight the benefit of GWT I noticed two things: - Current GWT developer are generally part of big to medium corporation and are mostly aiming to translate some legacy software to an intranet/extranet - Startup and younger developer tend to don't really care about GWT mostly because none of the app they use daily are built with GWT (they went to Google IO for chrome and android) Our most recent work done with GWT is t3ll.me: http://t3ll.me/I+AM+AWESOME/BECAUSE+I+AM+MADE+OF+GWT http://t3ll.me/I+am+not+your+average+and+boring+url/you+should+try+it(red)/(yellow)lol+@+url+are+not+awesome(blue) t3ll.me use VisualFox-FX and Bold which let you resize any HTML element to fit in a given box (try to resize your browser while playing with t3ll.me and you will get the idea).

I developed this code using a singleton class with hashmap to store a key value pair of user id and and it's counter and time. After initial, i was using this singleton class on client side, it worked fine for counters but when browser was refreshed, a new singleton object was created. I searched, and come to know that for security reason, javascript don't use shared objects, so i moved it to rpc call and make it server side object to overcome it, but when i tested it again, on refresh new object is created and data lost. That's expected behavior. You'll want to retrieve the stored data at application startup. I also tested the static hashmap to hold the data for application scope, but it has almost the same behavior, once refreshed the browser, its reset and old data is lost in it. It little different behavior from normal java web apps where we follow this approach. Does any one know how can i keep object at application scope in gwt ? Can you restrict your app to browsers that support local storage? In no way will the static storage class solve the problem you're describing. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to create a shared lib/utility class (client/server) ?
Ah well ok that works. I have already done this in a different context (globally overwriting a GWT client class), don't know why it doesn't came into my mind :) The only small issue that remains is that Eclipse always shows the VM implementation when clicking into the source code (jar library only contains VM .class + .java files and emulated GWT .java files without class files). Would be nice if Eclipse would jump to the emulated client source code but I don't think its possible. Although its working it just feels a bit odd if you suddenly see java.net.* classes if you use the lib only on client side. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Activities and Places - Handling several views
Hi everyone, I have some trouble managing Activity and Places with several views. The application is similar to an email client, it has 3 views: - View A: The list of all the folders - View B: The list of all the message within a folder - View C: The message content If the user loads the application, with no URL token, the views should be defined like this: - The View A should contain the list of all folders - The Views B and C should be empty If the user loads a message, let say through the URL with the message-1234 token, all the views should be updated: - The View A should highlight the folder that contains this message - The View B should highlight the message within this folder - The View C should display the content of the message Do you have any ideas on how to do that? Thanks a lot! Antoine. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group. To post to this group, send email to google-web-toolkit@googlegroups.com.

SVG scaling appears broken in IE9
I believe that this is not directly GWT's problem. It's IE's problem.
However I'll let folks know in case they want to venture down this
road.
The Context2d scaling methods are broke in IE9. Using GWT 2.3, I'm
drawing an Image into a Canvas widget. The image is larger than the
target, so I'm scaling it. With either of the approaches below, the
image displays in Firefox 7.0.1, Safari 5, and Chrome 13. The image
does **not** display in IE9.
void drawImage(Context2d context) {
context.save();
context.scale(scale, scale);
context.restore();
}
or
void drawImage(Context2d context) {
context.save();
context.drawImage(imageElement, 0, 0,
scale*(double)image.getWidth()-10,
scale*(double)image.getHeight()-10);
context.restore();
}
scale was computed as
image = new Image(...
image.addLoadHandler(new LoadHandler() {
public void onLoad(LoadEvent event) {
imageElement = (ImageElement)image.getElement().cast();
scale = Math.min((double)width/(double)image.getWidth(),
(double)height/(double)image.getHeight());
scale = Math.min(scale, 1.0);
drawImage(imageContext);
}
});
I'll add that context.drawImage(imageElement, 0, 0, width, height)
does work in IE, but of course depending on my image I may get a
distorted width:height ratio.
SVG is a new thing with IE9. Hopefully it will be right in IE10.

Re: GWT + EJB
Hi, I do think this is possible. I do have experience in EJB and also tried GWT. What I'm thinking is you can create a server side wrapper that calls business components - much like creating a business locator utility that will locate your EJBs on the server side (you can find a lot of tutorials with this). Then you need to import your stubs / references to your GWT application. Theres a lot of tutorials in the internet for EJB and GWT, just pick up the pieces and you'll surely mold these 2 great technologies. :) On Thu, Nov 3, 2011 at 3:15 AM, ph09 ph.hei...@googlemail.com wrote: Hello, I want to use EJB in my GWT Application, but I coulnd't find a current Tutorial.

Yes, this is the setup you should follow. If you use Maven you
can/should ignore the weird setup that GWT recommends (mixing source
