Re: Handling Multiple Click Events
Thanks I used the third option and it worked fine.
On Jul 21, 6:04 pm, Neha Chachra neha.chac...@gmail.com wrote:
Oh, sure. Here's one that should work:
import relevant classes like Button, clickhandler, Window
Button[] myButtons = new Button[2];
myButtons[0] = new Button(clickMeButton);
myButtons[1] = new Button(clickMe2);
for(int i=0;i2;i++){
myButtons[i].addClickHandler(new ClickHandler(){
Button sourceButton;
@Override
public void onClick(ClickEvent event) {
sourceButton = (Button)event.getSource();
if(sourceButton.getText().equals(clickMeButton)) {
Window.alert(works);
}
if(sourceButton.getText().equals(clickMe2)){
Window.alert(works2);
}
}
});
If you don't want an additional sourceButton, you can also do:
((Button)event.getSource()).getText().equals(clickMeButton); though as the
size of your array increases you'll end up making a lot of unnecessary calls
to getSource( ) that way.
Another approach would be to simply implement the ClickHandler in a separate
class, say if you have a lot of buttons and a long if/else branching. You
could do:
public class MyClickHandler implements ClickHander {
Button sourceButton;
@Override
public void onClick(ClickEvent event) {
sourceButton = (Button)event.getSource();
if(sourceButton.getText().equals(clickMeButton)) {
Window.alert(works);
}
if(sourceButton.getText().equals(clickMe2)){
Window.alert(works2);
}
}
}
MyClickHandler myHandler = new MyClickHandler();
myButtons[i].addClickHandler(myHandler); // for both your buttons
To be honest, I haven't done much work with ClickHandlers yet, so there
might be a better approach to handle such scenarios. In particular, I would
check if assigning and using DOM ids for the widgets is an option. I am sure
it must be, I just haven't gotten around to that. :)
Either way, I hope this helps.

Re: Command Pattern, MVP, EventBus
A short update on the original posting. I've now implemented the pattern I suggested in the original post in a reference application and it's running. My goals for doing the work were to address two issues: 1/ My GWT/GAE productivity: after a short learning curve it had sped up but it slowed right down again 2/ I found it easier not to write unit tests (a dangerous state of affairs) - they made the project messy, infiltrated the code, were difficult to write and slow to run The current implementation: * Adds a generic RPC mechanism (the pipe) * Doesn't use the command pattern. Instead everything is an event. Selected events from the event bus are sent over the pipe and responses are fired back. This makes the pipe invisible - no more coding service interfaces * I've added a layer (Stratus) on top of Bigtable-JDO inspired by Grails create, find, update, delete * Added a NullPipe and mock implementation of Stratus - I can now run end-to-end testing: presenters to database - i.e. everything but the composite itself without deploying to GAE. 7 unit test files run in around 0.5 seconds and developing is fun again! Findings so far * Ray's presentation was really helpful * Commands as events (aka asychronicity on steroids!): I'm kinda OK with this. I'm aware of David's posting above so I'm not 100% sure although still positive about my implementation. You do loose the procedural feel of the service call and AsyncCallback return although it is really asynchronous. I expected it to be difficult to test but it's not. I need more experience with it * I moved the definition of the Viewer (RR's Display interface) to the Presentation interface. Sorry Ray, it was in the wrong place * I dropped the idea of using HasClickHanders, HasValues, ... in favor of methods like getPassword(), and addSignInClickHandler() in the Viewer interface. I think it's a very elegant idea but it doesn't sit well with EasyMock and I prefer tested code to elegant code and don't think I loose much * MVP is great, really easy to test and so, to develop I still need to figure out a position on places / history (see posts above). My real application makes heavy use of History and I like it a lot. But I still don't have a comfortable pattern that joins the viewers and history together yet. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Command Pattern, MVP, EventBus
On 22 juil, 04:07, Jason A. Beranek jason.bera...@gmail.com wrote: I've been looking at the place service as well, but while I don't agree with exactly the structure in David Peterson's example, I'm not sure if the place service should fire an IssueEditEvent that drives some UI change. From the Ray Ryan presentation, my impression is the Place Service functions as an abstraction between client code/widgets and the History API allowing client code to decouple from the specifics of parsing and generating history tokens. The Place Service in that model is the sole handler of History events, and possibly one of the limited set of interfaces that programmatically set History (though you could use HyperLink widgets as the only means to control the token, however this complicates the creation of tokens). Yeah, right, Ray talks about place change events and components that could listen to those to be informed when they're in use or not and unregister/re-register their other handlers on the event bus (it's around 46:20 in the video). He doesn't talk about how to communicate with the place service to update the history token though. I'd say that either components have a dependency on the place service and call its methods directly (and the place service updates the history and fires a place change event to notify other components), or they themselves fire place change events and the place service listens to them. But those place change events are not that different from the events I described earlier (picked contact (the one with ID=12345)) As for the structure of the Place object, one approach is to use a simple key/value pair for the location, for example: #key #key/value This seems to be the same approach used in the current Gmail, Actually, in Gmail, it can also be label/My+Label/message-id, but it's still simply splittable on slashes to extract sub-parts. and seems like a good approach for some navigation schemes. Personally, I'd avoid more complex representation of Places, as it complicates parsing and Place change processing. However, your mileage may vary. The Google Documentation Reader http://code.google.com/docreader used to use XPointer-like tokens such as p(project1,project2)s (project1)t(topic) and now uses query-string-like tokens such as p=project1,project2s=project1t=topic. They're IMO as easy to parse as path-like tokens like Gmail uses; it's just a matter of taste (and how you'd like to model your internal API) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Determining a specific cell in a FlexTable
Your question is not 100% clear to me... but I will answer the
question as I understood it :-)
If you want to know what the coordinates are for a Widget in a table
then you will need to use the DOM API to find the TD and TR and
determine the index of these. There is no API available that gives you
the information, unless if you need the info when an event occurs
inside the table. In that case your can use the getCellForEvent method
(maybe you could use an onFocus/onBlur to lookup the coordinates ?).
I guess you are already using the DOM API, as I do, since you feel
like your are a bit hacking. I think it would make sense to request a
method getCell( Widget widget ) as a public API method since we are
now forced to look at the internals of the table widget - what if it
ever gets implemented differently ? Chances are low, but that just
means that it might just happen faster than you think according to
Muphy's law.

Re: InfoWindowContent JavaScript Browsers
I'm sorry to hear you're still having trouble. I can give you some general tips. If you are unable to debug in hosted mode, you might try using a javascript debugger like Firebug or IE8's developer tools. When you compile, add the option -style PRETTY to the build and the javascript output will be (somewhat) human readable. I just checked biooffice.at in ff3, chrome, ie8 and ie8 compatibility mode (ie7) and I saw that things worked in FF, but not the others. The code not being executed is custom javascript, that looks like its being generated on the fly and injected. Maybe it has to do with the way your script is being injected? The whole point of GWT is to reduce the pain of trying to write JavaScript - 1) take care of cross platform issues, 2) provide tools such as hosted mode that make it easier to debug, so I'm going to suggest that you refactor that code (in Java) so that GWT will handle the browser dependent baloney. For example, try using JSNI to wrap just the function 'topoGetAltitude()', and write all the rest of that code I see in the maps.log window in GWT. - the image tag becomes an 'Image' object - Change the altitude div to a label object (or DivElement) - The hard part will be wrapping the closure that gets passed to topoGetAltitude(). There are sample ways to do this of this in the GWT developer guide. Then, you can write a dummy function called 'topoGetAltitude()' in java script to mock the way the real function works. The mock would just asynchronously returns a number after a few seconds and test in an isolated project using hosted mode to iron out this issue. You could modify the mock to test your timeout logic too. If you want some more help writing your app in GWT and getting tips for debugging strategies, I suggest postng to the Google-Web-Toolkit group along with short snippets of code you want help with. If you think you've found a bug in the bindings, please file an issue (http://code.google.com/p/gwt-google-apis) with a small case that reproduces the problem that includes a description of the problem, Java source code and any errors you get from hosted mode or web mode. Often, the first step is to re-write the case in JavaScript to make sure the problem is related to the bindings and not the Maps API in general. -Eric.

adding my visualization graphs in a DockPanel with direction. Now If I
add graphs before attaching DockPanel, all graphs are rendered
properly in all browsers. But I have to do my work after attaching
DockPanel. In this case, in Mozilla and Chrome, only last graph added
in dockpanel get rendered where as in IE, all graphs are rendered
properly. Kindly note that this problem occurs only when I am adding
Graphs in DockPanel. In other containers like VerticalPanel
HorizontalPanel, I can add Graphs after attaching container, it works
well.
Below is a sample code to produce this case. Any help/suggestion will
be highly appriciated.
Code:
package com.example.simpleviz.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.DockPanel;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.Widget;
import com.google.gwt.visualization.client.DataTable;
import com.google.gwt.visualization.client.VisualizationUtils;
import
com.google.gwt.visualization.client.AbstractDataTable.ColumnType;
import com.google.gwt.visualization.client.visualizations.BarChart;
import com.google.gwt.visualization.client.visualizations.PieChart;
import
com.google.gwt.visualization.client.visualizations.PieChart.Options;
public class MyClass implements EntryPoint {
public void onModuleLoad() {
VisualizationUtils.loadVisualizationApi(new Runnable() {
public void run() {
Widget bar = createBarChart();
Widget pie = createPieChart();
DockPanel d = new DockPanel();
RootPanel.get().add(d);
d.add(bar, DockPanel.NORTH);
d.add(pie, DockPanel.NORTH);
}
}, new String[] { BarChart.PACKAGE, PieChart.PACKAGE});
}
private Widget createPieChart() {
DataTable data = DataTable.create();
data.addColumn(ColumnType.STRING, Task);
data.addColumn(ColumnType.NUMBER, Hours per Day);
data.addRows(1);
data.setValue(0, 0, Work);
data.setValue(0, 1, 10);
Options options = Options.create();
options.setWidth(200);
options.setHeight(100);
options.set3D(true);
options.setTitle(My Daily Activities);
PieChart pie = new PieChart(data, options);
return pie;
}
public Widget createBarChart() {
DataTable data = DataTable.create();
data.addColumn(ColumnType.STRING, Year);
data.addColumn(ColumnType.NUMBER, Sales);
data.addColumn(ColumnType.NUMBER, Expenses);
data.addRows(4);
data.setValue(0, 0, 2004);
data.setValue(0, 1, 1000);
data.setValue(0, 2, 400);
BarChart.Options options = BarChart.Options.create();
options.setWidth(200);
options.setHeight(100);
options.set3D(true);

BarChart barchart = new BarChart(data, options);
return barchart;
}
}

Project setup that allows working with both hosted mode and web mode side by side?
Hi, I am looking for a project setup that allows me to work easily with both hosted mode and web mode (including RPC). I am getting the exception below, whenever I start up hosted mode after I have started it in web mode (i.e. war/myModule directory contains the compiled code for web mode). If I am starting hosted mode on a clean war/myModule directory then it works ok. To workaround it I thought to add a specific module for hosted mode like this: module rename-to='myModuleHosted' inherits name='my.company.gwt.MyModule'/ set-property name=user.agent value=gecko / set-property name=locale value=default / /module And then start up this from the shell (with args: -startupUrl MyModuleHosted.html my.company.gwt.MyModuleHosted). This works well as long as I dont do any RPC calls. RPC calls however fail since they try to address myModuleHosted/ myServicePath whereas the service is still available under myModule/ myServicePath. Any ideas to get the service available as myModuleHosted/myServicePath instead? Or any other ideas for a setup?

Re: Project setup that allows working with both hosted mode and web mode side by side?
Hi Rintcius What IDE are you using and what is your J2EE contianer? I managed to use the -noserver -startupURL options... This allowed me to get my back end (services) debuggable on my servlet container (in this case websphere, which had already been started) and the front end in hosted mode. RPC works fine in this set up.

Re: Pre-Compress GWT compiler output for web server
I've found an interesting tool for Java EE applications and Tomcat server: :-) http://www.xucia.com/#Resource%20Accelerate :-) ResourceAccelerate... it can cache the gzip output of tomcat and thereby reduces the need to re-compress files for every request. Great! What do you think of it?

I am using the Apache Tomcat web server. I successfully managed to enable GZIP output for the Tomcat server by editing the server config file. It works fine. However, this way the data is compressed on-the-fly by the web server for every request which considerably increases server CPU load. Is this assumption correct? Is there a way to pre-compress the contents of my GWT app and have this pre-compressed content delivered by the web server? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: ClassCastException only in Chrome and OBF mode
ok - I think now I tracked it down first it turned out, that the ClassCastException occured only when I read a special Enum-Value from the database. which was strange, because it was an enum with 6 values: 5 worked, one had the ClassCastException when looking closer at the enum I noticed, that it uses the generated GWT-i18n Text-Interface to return a language dependant value I think that lead me to the solution: the problem was, that your build-system used GWT 1.5.0 to generate the Text-Interfaces but later 1.5.2 to compile the application: I guess that was the problem Now I upgraded to GWT 1.5.3: I use GWT1.5.3 to generate the Text- Interfaces and also 1.5.3 to compile the application now it works just for reference: * It also worked before in Safari 3.2.2 On Jul 21, 7:20 pm, Paul Robinson ukcue...@gmail.com wrote: Do you know which RPC methods trigger it?

How to configure Source path to use another project (jar) file
Hi all, I am very new to GWT and am trying to POC the way forward for new development. I am really hoping to be able to tell my boss this is the way we are going to do it from now on.. because GWT looks really neet even if the EventBus etc looks a little dauting. Anyway.. i digress I have sucessfully managed to get the StockWatcher app running and got it using RPC to my websphere appserver. I had it configured with my GWT classes and my persistence (OpenJPA in this instance) and entitiy classes in the same project. Now i want to split those projects out into 2 seperate ones, i.e. StockWatcher war and StockWatcherJPA. Essentially i want my entities to reside in the JPA project. I believe my project references are setup correctly however when i try and do a GWT Compile i get errors stating No source code is available for my Entity class (which resides in my JPA project). Now i think that i need to configure my source path, or inherit another module (?? maybe I am wrong) but i cant figure out how to do this. I hope that makes sense and hope that someone can push me in the right direction. Any help will be greatly appreciated.

Re: How to test GWT MapWidget?
Help pl :-)
On 21 Juli, 19:17, Dalla dalla_man...@hotmail.com wrote:
Hi all
I´m trying my best to implement the MVP pattern to be able to create
fast unit tests,
using JUnit4 only instead of using GWTTestCase.
I´ve trying to create a simple application using the GWTGoogleMaps
API,
but i´m having trobles writing tests for my presenter.
The presenter, somewhat stripped, looks like this:
public class MapDisplayPresenter {
HandlerManager eventBus;
MapDisplayInterface widget;
MapData data;
public MapDisplayPresenter(MapDisplayInterface mapDisplayWidget,
MapData data,
HandlerManager eventBus) {
this.data = data;
this.eventBus = eventBus;
this.bindDisplay(mapDisplayWidget);
}
private void bindDisplay(final MapDisplayInterface widget) {
this.widget = widget;
widget.getMap().addMapClickHandler(new MapClickHandler() {
public void onClick(MapClickEvent event) {
widget.getMap().addOverlay(new
Marker(event.getLatLng()));
}
});
}
interface MapDisplayInterface {
HasClickHandlers getButton();
MapWidget getMap();
HasText getTextBox();
ListBox getList();
}
}
Since the MapWidget doesn´t implement alot of interfaces, I couldn´t
find a good way to access the MapWidget
without exposing the entire object instance through my
MapDisplayInterface.
The problem comes when I try writing tests for this presenter.
I tried using JUnit, extending it iwth Jmock, further extending it
using JDaves unfinalizer,
but sooner or later, the MapWidget or one of it´s subclasses throws an
exception.
So are there any good ways of writing tests here without using
GWTTestCase?
Are there any better ways of implementing my own interface that doesn
´t involve exposing
the entire MapWidget?
Would Selenium (which I have never used) be a better idea?

Modify PHP generated content from database by JavaScript
Hi, I have a list of notes (data = ID, subject, description, date) which is generated by PHP from a MySQL database. Now I want the user to change the notes by using JavaScript. The user can click on a note to see all the data of it on a single page. By clicking on one of the data the label shall change to a textbox to let the user change the data. Is it possible to merge the existing PHP code like accessing the database and displaying the data with the needed JavaScript or do I have to build the HTML code with labels and textboxes and database accesses again? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Image Bundle not working in IE
So, I seemed to have two problems, one my Server is not logging errors, I should have seen that 403 error, but didn't. But I was able on your suggestion mess around with IE's Developer's tools. I figured out how to use the pointer to figure out the call made and I figured out the problem. The alpha loader doesn't do a load with say, celticlock/imagebundlestuff.cache.png, it loads http:// www.celticlock.com/celticlock/imagebundlestuff.cache.png. So what happens is it looked like someone was hot image linking it. So I checked the setting and image linking was enabled, I disabled it and *BAM* it worked great!

Re: Gmail this is taking longer than usual message
How do you plan to implement the timer? I assume it will be external to the GWT application - so perhaps the app will make a change on a predefined spot in the host page DOM, and the script with the timer will check for it? It's an interesting problem - I definitelly don't want my potential clients to see an app that doesn't load.

Using SOYC

I found that using GWTCompiler class the -aux folder gets created, but running SoycDashboard fails with Error creating html file. Unexpected end of ZLIB input stream.

Re: Generators don't work good with refresh button

I'm not sure how exactly the JTypeOracle stuff works, but I like to be able to see and/or debug through the generated code, plus there's no extra ClassLoading involved - the generated stuff is 1st class GWT objects.

It all boils down to the fact that client code is loaded in ComplingClassLoader and the Generator is loaded in a different ClassLoader than that. Reflection is not that nice.

Suggestion: Toggle style name
Eventually I find my self doing this:
toggleStyleName = !toggleStyleName;
if (toggleStyleName)
{
widget.addStyleName(SomeStyleName);
}
else
{
widget.removeStyleName(SomeStyleName);
}
So here goes my 2 cents: instead of manually toggling a style name, it
could be simply:
widget.toggleStyleName(SomeStyleName);
jQuery actually has such a method, it's usefull, helps keep my code
clean.

Re: JSNI issues
Hi, Adam. Thanks a lot for your effort! I found a way to eliminate the
problem, namely by directly compiling for web mode, and not for hosted
mode (I am still on GWT 1.5. I know, it is high time I ported!).
I do not understand it though. When I include raw JS files from the
Google Visualization API, the GWT compiler for hosted mode does not
complain, i.e. no errors/exceptions for
$wnd.google.visualization
But in the case of Protovis
$wnd.pv
up pops a com.google.gwt.core.client.JavaScriptException.
Any ideas why?
waqar :)

in your browser to see what's loaded etc as you're going to need it
when you get into trying to access the library and going further, but,
the following works for me to access the library.
1. In my applications .gwt.xml file I have put: script src=protovis-
r2.6.js/
2. I also have defined my module in the .gwt.xml file as follows:
module rename-to='testAA'
3. I'm using GWT1.6, so the protovis-r2.6.js file needs to go in
within the war file, i.e. it goes in the folder /war/testAA/
4. In my application I just create a simple JSNI method
public native JavaScriptObject getVis()/*-{
var vis = new $wnd.pv.Panel().canvas(test);
return vis;
}-*/;
5. In my onModuleLoad I simply call the method and alert the fact
that I have an object
public void onModuleLoad() {
JavaScriptObject v = getVis();
Window.alert(v.toString());
}
that tells me I have got a valid JavaScript object and I see no
exceptions or errors.
Hope that helps, or at least gives you some hints.

It could still be a similar thing; I'm not 100% clear what you are
trying to do above, but it looks like your steps are:
1) Load an external JavaScript library, e.g. protovis.js
2) Run some other JavaScript which creates something in the DOM, e.g.
the vis = new pv.Panel().canvas(PVis); .vis.render(); part
3) In GWT access the rendered PVis component.
If that's correct, then by moving the protovis.js to the .gwt.xml
part your ensuring that the library loads before your GWT, but it is
still possible that part (2) is executing after your GWT code, and
hence it is not available to your GWT code when it runs. You could
wrap that code in it's own file and load through the script tag
(though I'm not sure about ordering in the gwt.xl file).
I'd also suggest you use some debugging tools (Firebug for example in
Firefox) to look at what your code is doing, that should show you the
scoping of pv etc.
(though you might be better off writing a wrapper using JavaScript
Overlay types (http://googlewebtoolkit.blogspot.com/2008/08/getting-to-
really-know-gwt-part-2.html) that would let you merge GWT and the
protovis library in a more natural style, than the approach you're
taking just now)
Good luck,

Hi,
It might be the case that in both cases your GWT code is loaded and
executing before the browser has loaded your externally referenced
JavaScript file. To remove that possiblity, you can place the
script tag you have in the HTML into your module's .gwt.xml
definition, i.e.
module
inherits name='com.google.gwt.user.User' /
script type=text/javascript src=protovis.js
/module
With this sett up, the GWT boostrap code should ensure the library
JavaScript is loaded before your GWT code executes.

Re: Pre-Compress GWT compiler output for web server
A solution for the *.cache.html files is to gzip them to .cache.html.gz files. If you are using Apache as your web server you can then modify the mime.conf file (found at /etc/apache2/mods-enabled/mime.conf) by uncommenting: AddEncoding x-gzip .gz .tgz and commenting: #AddType application/x-gzip .gz .tgz This means that my apache server will send the .cache.html.gz files in replacement for the .cache.html files and also send the response header: content-encoding=gzip This can also be done in a .htaccess file (RemoveType and AddEncoding) placed in the cache folder.

If I run the app inside Eclipse in hosted mode and then do 'mvn
package' (without the clean), everything works.
Any idea of what I am not doing or doing wrong here?

Re: JSNI: window vs $wnd
Cool, thanks again for the help. I am confused by the last paragraph but I think it's because you're looking at the code at the first URL rather than the second one: http://code.google.com/webtoolkit/tutorials/1.6/Xsite.html The code at that URL uses 'window' instead of $wnd. So I think this does pollute the window namespace. No? -Mike On Jul 20, 6:41 pm, Thomas Broyer t.bro...@gmail.com wrote: On 20 juil, 22:26, mike mikebannis...@gmail.com wrote: Darth, ...ahh, great thanks. I got to $wnd to work for code in the cross-site communication tutorial. I think the problem was that I was using document and $wnd rather than $doc and $wnd. I haven't completely worked out in my head why the former wouldn't work but it seems sensible that you would need to make sure it's all either happening on the host page or all in the iframe. You add your script node to 'document' (which lives in 'window') but you define the callback function in $wnd. When the script loads, it calls a function called callbackID (where ID is a counter); in JavaScript, this is equivalent to calling window.callbackID (because 'window', and window.window, and window.window.window, and etc. is the global object); but as I said before, the function doesn't exist, as it has been actually defined in $wnd. Incidentally, if you add-linker name=xs / in your gwt.xml, it'll work, because in this case $wnd == window and $doc == document. Any guess why the tutorial uses window/document rather than $wnd/ $doc ? That way, it doesn't pollute the window name space (only the $wnd name space, which is only ever used by your GWT compiled code), as it uses window[something] = ... constructs (incidentally, if you add- linker name=xs /, it *will* pollute the window namespace).

jetty classpath in hosted mode?
how can the classpath for the embedded jetty in hosted mode be configured? problem is that i need to read and write files from an rpc server implementation on the server side. as long as these files are located in the war directory everything is working fine. but i'm not able to put them into another dir, out of the war dir. so how can the classpath be configured? passing -cp in the debug configuration has no effect. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: gwt 1.6 and oophm, how to?
Thanks for reply, I actually did get oophm work with gwt 1.6/1.7. Wanted to share some feedback. Building from trunk, I first run into issue #3556 (http:// code.google.com/p/google-web-toolkit/issues/detail?id=3556) which luckily had a workaround documented. http://code.google.com/p/google-web-toolkit/wiki/UsingOOPHM explains the procedure (no need to compile oophm from branches/oophm), but being not well-versed in GWT, I had it tough realizing that BOTH gwt- oophm.jar and gwt-dev.jar need to be included in my project classpath above the GWT 1.6/1.7 jars. Can a request be placed to extend UsingOOPHM or can I submit a explanatory paragraph for review? After figuring that out the rest worked pretty well. Really really happy, since in-process hosted mode ceased to work for some reason after I embedded GWT code in a jsf page, and I now have firebug!!! Best wishes, denis On Jul 21, 11:59 pm, Sumit Chandel sumitchan...@google.com wrote: Hi Denis, Unfortunately, you'll need to work from trunk for both GWT core and OOPHM as the two are under active development, and the OOPHM branch is generally staying in sync with changes in trunk. Many GWT developers have been using trunk successfully during development, but keep in mind the disclaimer that trunk is bleeding edge code and not recommended for production. That said, the next major release will include OOPHM, so you can look forward to using it in a stable release soon. As for using hosted mode in GWT 1.7, could you elaborate a little more on what issues you experienced when trying to start up hosted mode?

How does sinkevents works by default?
Hello, I'm developing an application using gwt . I never used events before so I am still learning how they work in GWT. The sinkEvents() as I understand it is used if you want your widget to react to events. But what does it do to events if it doesn't handle them? Does it bubble them up so that other widget can try to handle them? Or if I do sinkEvents() on a widget it keeps all events from passing? When I fire a event does it propagate along the widgets until something handles it? For example, if I have a image inside a vertical panel, and that panel is inside a Absolute panel. When the image fires a clickevent, if the vertical panel does nothing to it, will it propagate to the Absolute panel? Thanks in advance, and I'm sorry if I was too confusing.

GWT compiler doesn't ignore (java.xml) annotations
Hello,
I was under the impression that GWT compiler ignores unrecognized
annotations. Well, I have a simple test class with some java.xml
annotations on it. The source for those annotations is not on the
classpath. I read that if I put the source there, I should have no
problems, but for this example I didn't want to do that. My class:
@XmlType(name = point)
public class Point {
@XmlAttribute public double x;
@XmlAttribute public double y;
public Point() {
}
}
If I remove the annotations the compilations finishes without
problems.
My question is: does gwt ignore the unrecognized annotations or not? .
I remember reading that it does since version 1.5. I am using version
1.7. Have I misunderstood something important about the compilation?
On the client side I have no need for some annotations, but on the
server side I do. I would like not to rely on a facade/dto solution to
have my classes compile properly nor would I like to be forced to
include a source on my classpath unnecessarily.
Thank yall

Programmatically resize browser window
For the GWT app I'm developing, I need to programmatically change the
height of the browser window. Is there a way to do this in GWT? I've
tried the following:
public static native void setWindowHeight(final int height) /*-{
$wnd.resizeTo($wnd.outerWidth, height);
}-*/;
But this does not just change the height, it also messes with the
width. Moreover, I would like to keep this resizing functionality
within GWT Java code (this uses JSNI).

But I was able on your suggestion mess around with IE's Developer's tools. I figured out how to use the pointer to figure out the call made and I figured out the problem. The alpha loader doesn't do a load with say, celticlock/imagebundlestuff.cache.png, it loads http://www.celticlock.com/celticlock/imagebundlestuff.cache.png;. So what happens is it looked like someone was hot image linking it. The URL isn't in cause here, it's the use of AlphaImageLoader which causes this, because it is a ActiveX that runs outside the HTML page, it doesn't have access (or just does not use, which is more probable) to the HTML URL to use it in a Referer HTTP header. So I checked the setting and image linking was enabled, I disabled it and *BAM* it worked great! Great!

Re: Programmatically resize browser window
Edit: this actually does not interfere with the width of most browsers
- it resizes to the previous width and new height. It does mess up
the width in my Google hosted mode browser though for some reason.
I actually would prefer something that would resize the client area of
the browser (i.e. excluding the browser's toolbars and scrollbars
etc.) instead of the window itself.
For example, com.google.gwt.user.client.Window has the following
methods: getClientWidth() and getClientHeight(). I would like
something that would be equivalent to setClientWidth(int width) and
setClientHeight(int height).

The sinkEvents() as I understand it is used if you want your widget to react to events. First, starting with GWT 1.6, you don't have to deal with sinkEvents in your code, just use addDomHandler vs. addHandler. addDomHandler calls sinkEvents in addition to calling addHandler. sinkEvents registers handlers for the appropriate events on the DOM element used by the Widget (see Widget#getElement()). When such an event is fired (on the DOM, generally by the browser), it's handled by Widget#onBrowserEvent which just delegates it to the handlers you registered. The only exception is mouseover/mouseout events, which are only ever delegated to the handlers if they actually go in and out of the Widget#getElement() (i.e. not from a child element to another child element). If you know how DOM events work (bubbling, capture, cancelable, etc.), GWT doesn't change that. But what does it do to events if it doesn't handle them? Nothing special. Does it bubble them up so that other widget can try to handle them? Or if I do sinkEvents() on a widget it keeps all events from passing?

When the image fires a clickevent, if the vertical panel does nothing to it, will it propagate to the Absolute panel? Yes, but neither VerticalPanel or AbsolutePanel give you the opportunity to register a ClickHandler, so you won't be able to handle the event at this higher level in the widget tree. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT 1.7 Now Available
Hi everyone, (Most people are probably already quite aware of the new GWT 1.7 release, but we wanted to send out an official announcement we could pin to the top of the message list.) GWT 1.7 is a minor update that adds better support for Internet Explorer 8, Firefox 3.5, and Safari 4. Each of these new browser versions introduced at least one change that negatively impacted compiled GWT modules, so we recommend that you do update to GWT 1.7 and recompile your existing applications to ensure that they work with the latest versions of browsers. No source code changes on your part should be required. Normally, a minor update such as this would have been named 1.6.5 (the previous latest version of GWT was 1.6.4), but we did add the value ie8 to the user.agent deferred binding property, which could impact projects using custom deferred binding rules that are sensitive to that property. Thus, we went withGWT 1.7 rather than GWT 1.6.5, to indicate that you may need to pay attention to that change. Details are in the release notes. In every other respect, this is just a bugfix release, so in the vast majority of cases, the update-recompile process should be nearly effortless. Download here: http://code.google.com/p/google-web-toolkit/downloads/list?can=1q=GWT+1.7.0 Cheers, Bruce, on behalf of your friendly GWT Team --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

History -- invalidating a page
I hope that this is an easy question for all of you. I apologize if this has been answered before. I have set up security with LDAP and ACEGI, using jsp pages that are called when requests are intercepted via ACEGI. It works great. Upon successful login and determining that the user has the appropriate role, the gwt application is entered. There are two problems I have, and I think that they are related. 1.) When you press the back button, you are left with the original state of the page you first came to. So, tab pages have default values and all of that. How do you keep that information when you go back in the browser? 2.) Once I logout the user, it is still possible to visit the old page and do work on it, even though in reality the session has been invalidated. If I were to branch to another page from the original one, I would be redirected to the login page, but not upon orginally hitting the back button. How do I tell the browser that the old page is now invalidated? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Interface not RPC serializable
I don't think so, as I believe that is how it's supposed to work. From
the docs (http://code.google.com/webtoolkit/doc/1.6/
DevGuideServerCommunication.html#DevGuideSerializableTypes):
A type is serializable and can be used in a service interface if one
of the following is true:
The type is primitive, such as char, byte, short, int, long, boolean,
float, or double.
The type an instance of the String, Date, or a primitive wrapper such
as Character, Byte, Short, Integer, Long, Boolean, Float, or Double.
The type is an enumeration. Enumeration constants are serialized as a
name only; none of the field values are serialized.
The type is an array of serializable types (including other
serializable arrays).
The type is a serializable user-defined class.
The type has at least one serializable subclass.
... and ...
A user-defined class is serializable if all of the following apply:
1. It is assignable to IsSerializable or Serializable, either because
it directly implements one of these interfaces or because it derives
from a superclass that does
2. All non-final, non-transient instance fields are themselves
serializable, and
3. Prior to GWT 1.5, it must have a public default (zero argument)
constructor or no constructor at all.
4. As of GWT 1.5, it must have a default (zero argument) constructor
(with any access modifier) or no constructor at all.

Yeah I've left that out in the example, it of course is marked with

However! - I've found a solution (just needed to recall that I've had

A Class (or Enum) type extending the said non-serializable interface
(MyIface in the above example) needs to be defined in the same package
as the interface. The compiler warning is then not produced.
I've scanned GWT-Issues (and GWT docs) for this, haven't exactly found
it - should I fill this as an Issue?

Re: Pre-Compress GWT compiler output for web server
It is dead simple to create a simple in-memory cache in your web application for gzipped data. Gzip the web page in memory the first time it is created and then use this for subsequent requests to that resource.

I am using the Apache Tomcat web server. I successfully managed to enable GZIP output for the Tomcat server by editing the server config file. It works fine. However, this way the data is compressed on-the-fly by the web server for every request which considerably increases server CPU load. Is this assumption correct? Is there a way to pre-compress the contents of my GWT app and have this pre-compressed content delivered by the web server? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

You bring up a good point regarding preference, and I think its relevant to this thread in considering that there isn't a clear cut approach to the design patterns presented that is right or wrong for any given application.

Re: Command Pattern, MVP, EventBus
On Jul 22, 6:59 am, Daniel Wellman etl...@gmail.com wrote:
So it seems it's a tradeoff in how much test coverage you need --
expose the low-level HasXyz interfaces in your view if you need more
automated test code coverage, or use a gateway interface to the view
which exposes higher-level methods like getPassword(). Using this
gateway means you lose test coverage of which specific widgets are
wired to a given Presenter callback, but you may be able to live with
that risk (a quick manual exploratory test might give you that
confidence).
If you think about it, there is more a spectrum than a clear
separation between HasXyz as a low-level interface and a gateway
interface to the view. Based on Ray's talk, the Display interface for
each presenter is in effect the Gateway interface for the View and the
HasClickHandler or HasValue interface components expose the expect
interaction with that object. While these appear to be low-level, it
all depends on how the View itself is implemented. For example, I
could have a display interface for a UI that displays a list of
contacts having a function like this:
interface Display {
...
HasSelectionHandlersInteger getSelectionButton(){}
..
}
The Display Gateway object specifies that the SelectionButton is
responsible for producing selection events that return the index of
the list item selected. However, from a UI perspective this could be
implemented as a selection on a ComboBox, an HTML List, response to
clicking on a FlexTable row, clicking on a Radio button, or even
clicking a CheckBox next to the list item and then clicking on a Make
Selection button object. The level of granularity depends, like you
said, on how much interaction you want testable using JUnit tests
rather than GWTTestCases, but it is not an either/or choice. I do see
value in having HasXyzHandlers interfaces returned in the View Gateway
interface as a way of testing asynchronous interaction is correct,
since asynchronous interaction cannot be statically verified at
compile time.

Re: Selection of Widgets
Hi Ewald,
Sounds like you want to prevent the default event handling of the
browser. You'll need to add some event handlers to your HTML widget
and the call the preventDefault() method in them. For example:
HTML widget = new HTML();
widget.addMouseDownHandler(new MouseDownHandler(){
public void onMouseDown(MouseDownEvent event) {
event.preventDefault();
}
});
(you might get away with just handling the mouse down event, you might
have to also handle mouse move - I can't remember without building a
full example myself, but you get the point, hopefully).
Regards,
Adam

[gwt-contrib] Re: Proposal for improving JDO/JPA RPC support
Hi Dan, That sounds to be a really good step in the right direction. This mecanisms seems to cover all the nominal use cases that we would face regarding the different o/r mapping impl. I would just make a few remarks : 1) When you call all the setXX() methods when the object is sent back to the server, the o/r mapper will assume that those fields have been modified and the dirty state tracking (which is activated before the setXX() call if I well understand) will raise an update operation for all the fields. I think you have to compare bean n-1 field values and bean n field values to call only the setXX() for the modified values. What about collection ? Hibernate provides a PersistentSet that ensure the object state tracking, will you call setXX() for all items of client data ? 2) If you analyze an enhanced entity in the Hibernate land you will see that it contains many coarse-grained information, like a SessionImplementor (it depends on the dynamic proxy factory and impl you have used) - https://www.hibernate.org/hib_docs/v3/api/org/hibernate/proxy/ProxyFactory.html. Serializing those data in a String based representation could be potentially harmful in term of bandwith and payload. Why not providing a way to store this client data info in the HttpSession ? Sami On Mon, Jul 20, 2009 at 8:06 PM, Daniel Rice (דניאל רייס) r...@google.comwrote: Hi all - I've been working on a patch to improve support for RPC of persistence-enhanced objects that would replace the one I recently submitted as trunk revision 5672. I'd like to give those of you who are interested in the interaction between RPC and persistence a chance to help me validate the design before moving forward. The idea is to be able to deal with different persistence mechanisms in a way that does not depend too much on the details of their implementations. We assume that the persistence mechanism provides a way for instances to be detached from the object store, serialized, deserialized, and reattached in a well-defined way. Our strategy leverages this capability as follows: 1) User code on the server detaches the object and places it into a state such that serialization is valid 2) GWT detects whether any instance fields are present on the object that were not known to client code 3) GWT performs hybrid serialization: a) GWT uses its regular RPC mechanism for the client-visible fields b) GWT uses Java serialization for any additional server-only instance fields c) GWT encodes the results of step (b) as a String d) GWT prepends the encoded String to the regular RPC data and transmits to the client 4) Client code treats the object in the normal way and does not interact with the data from step (3b) 5) When the object is sent back to the server, the normal RPC mechanism is altered as follows a) the encoded server data is decoded and deserialized into the new object instance b) the client data is populated using setXXX() method invocations rather than by directly setting field values All this is done only for classes that can be send bidirectionally, and which are determined to be (potentially) enhanced. The potential for enhancement is signaled in one of three ways: o The user adds the fully-qualified class name to a 'gwt.enhancedClasses' configuration property o The class is determined to have the JDO @PersistenceCapable annotation with detachable=true o The class is determined to have the JPA @Entity annotation If a class is determined to be potentially enhanced, the list of fields known to the client is added to the '.gwt.rpc' file that contains the RPC whitelist. This list is used by step 2 of the RPC process which compares the set of client- and server-visible fields. Step (5b) is necessary to accommodate mechanisms like that of JDO, where the setter methods are enhanced to provide object state tracking (dirty bits). If we were to set the fields directly, the object detached state would not be updated properly. My hope is that this mechanism would be general enough to support a variety of persistence mechanisms without the need to add a lot of special-case code. I'm looking forward to any comments that you have as to whether this will work with your favorite persistence API, or any other thoughts that you have.

So my proposal would be to use deferred binding to emulate these features on browsers that do not support the latest features (IE8...) and to use a lightweight css based impl on WebKit/Firefox 3.5. In my example of DecoratedPanel the 9x9 approach should be kept for IE and a null impl with css based rounded corners should be available for Firefox (css have to match the given theme). Animations that come with the standard widgets should also be able to fallback to css based animations when available. I've been also reading some posts about the new datagrid html extension and thought it might be clever to have a look at the spec when moving the tables from incubator to trunk to see how far the concepts match. Would be very cool to have a native table implementation on WebKit browsers while other fallback to gwt impls.

[gwt-contrib] Re: RR : Emulate JS stack traces (phase 1)
This patch took me hours to absorb. It sounds simple to modify the
compiler to emulate stacks, but understanding precisely where the stack
updates need to happen is difficult!
The implementation is very clean. There are just two nits in the
comments.
The line number recording looks like it should have a couple of
exceptions where it includes a line-number updating statement just to be
safe.
Most significantly, it looks to me like one thing is missing from the
finally block handling, and a great deal of the try-finally handling in
there could safely be omitted. Please check out the comments on this
and see if you agree.
http://gwt-code-reviews.appspot.com/47816/diff/1/5
File dev/core/src/com/google/gwt/dev/js/JsStackEmulator.java (right):
http://gwt-code-reviews.appspot.com/47816/diff/1/5#newcode132
Line 132: // $stack[$stackDepth = stackIndex] = currentFunction
This is safe, but why is it necessary? I would have thought that
$stackDepth = stackIndex is enough. Shouldn't $stack[stackIndex] be the
same until this function decrements stackIndex and returns?
http://gwt-code-reviews.appspot.com/47816/diff/1/5#newcode174
Line 174: * exitingEarly $stackDepeth = stackIndex - 1;
There is no way to know for sure! It could depend on whether the try
block throws an exception or simply fell off its end. Further, the
throw might not be apparent in the code; it could have been thrown by
some other function that the try block calls.
Maybe this pop code is not needed. See my next comment.
Is it even necessary to bother? See my next comment.
http://gwt-code-reviews.appspot.com/47816/diff/1/5#newcode184
Line 184: * the stack depth.
This is a clever approach, and would seem to mean that it's not
necessary at the *throw* site to update the emulated stack. Instead, it
gets updated as soon as user code (as opposed to JSVM code or browser
API code) starts running again.
The only places user code can restart after an exception are catch
blocks and finally blocks. Here you describe updating catch blocks.
Wouldn't finally blocks need the same treatment?
Going on from there, since catch and finally blocks reset the stack at
their entry, is it necessary any longer to bother popping in finally
blocks? That looks like a vestige from an earlier approach where
exception throws did cause immediate stack updates. The newer approach
appears to be that pushes happen at function entry, pops happen at
function exit, and just-in-case stack resets happen at the top of
finally and catch blocks.
As an added bonus, the code should be simpler, because exitBlock and
earlyExitName variables are no longer needed.
http://gwt-code-reviews.appspot.com/47816/diff/1/5#newcode204
Line 204: * arbitrary point.
It's not an arbitrary point. If I understand correctly, it is if an
exception occurs at the currently visited location? This variable then
gets updated by visit() methods so that it stays accurate.
http://gwt-code-reviews.appspot.com/47816/diff/1/5#newcode360
Line 360: earlyExitNames.remove(exitBlock);
This statement looks strange. Is it supposed to happen before the
previous one?
http://gwt-code-reviews.appspot.com/47816/diff/1/5#newcode400
Line 400: // Don't need a pop after a throw or break statement
There are other cases where a function might not fall off the end. For
example, there might be an if statement, and both branches might end
with a return or a throw.
I think an extra pop would be fine, because JavaScript is looser than
Java about unreachable code. However, it is worth at least commenting
that the point here is not to catch all cases, but to remove the excess
pops in the most common cases.
http://gwt-code-reviews.appspot.com/47816/diff/1/5#newcode604
Line 604: private String baseName(String x) {
The convention seems to be that x is an AST node. This variable holds
a fileName or the like.
http://gwt-code-reviews.appspot.com/47816/diff/1/5#newcode620
Line 620: // Same location; ignore
This can give wrong line numbers for looping statements, because the
visitor order is a subset of the possible control-flow paths. Here's an
example:
for (int i = 0; i someFunction(); i++) {
doStuff(i);
}
Suppose someFunction() throws an exception on its *second* invocation
but not its first: The line numbers are then incorrect. To correct
this, a simple way would be to add paranoid extra line-number updaters
for for loops and while statements.
http://gwt-code-reviews.appspot.com/47816/diff/1/5#newcode663
Line 663: private boolean recordLineNumbers =
Boolean.getBoolean(gwt.dev.stack.recordLineNumbers);
There is now a module CompilerParameters.gwt.xml that has misc. compiler
settings that most users won't touch. While it's not a big deal, it
seems helpful to keep things to the smallest scope that makes sense.
Module scope is smaller than property scope.

I think that popping in a finally block is necessary only when you have
a return statement in there. Maybe the exitingEarly variable should
be called exitBlockExitsFunctionNormally. The amended pattern is that
a pop is necessary anywhere normal flow control might exit the function.
function foo() {
try {
if (maybe) {
return;
}
} finally {
// maybe function exits and pops here
}
otherCodePossiblyExecuted();

I agree that there is no real reason to have special handling for throw

[gwt-contrib] Re: GWT emulation of HTML5/CSS3 features
I think it is helpful if we distinguish between optional and mandatory features. If GWT would come with a set of widgets or library components that behave slightly different on different browsers this might not be bad in general. I'm aware that the general approach of GWT is to write software once and run it almost everywhere with identical results. But I can imagine several areas where it may be appropriate to have e.g. widgets that look even better when the rendering engine supports 3d animations etc. If the developer can use the widget as is and will get a default behavior on all browsers and an extended behavior on top on some of them, this would be beneficial IMO. Think of a TabPanel widget that takes advantage of the new funky 3D animation and transition feature on WebKit and provides a working default implementation for browsers not supporting CSS3 looking a little bit more boring. When it comes to libraries like Database storage it would be helpful to have a dummy implementation that will do nothing in case when no persistence is available and to provide some isAvailable() method for each additional feature.

[gwt-contrib] Re: Generators and hosted mode refresh
Hey guys. Imho having Generators in the CCL club is icing on the cake...very cool but not really essential. I can confirm using JavaRebel solves both problems (generator code change, and gin module changes, @Inject added etc). For the time being I think this is a reasonable compromise for people who want to change gin code in hosted mode. afaik you don't need to supply source code of the generator. Should we want them fully in the CCL club this would break backwards compatibility. As Class loading goes. How about: Load generator and all its libraries from SystemCL to a GeneratorClassLoader and load all gwt client code from CCL into GeneratorClassLoader to. Like a hybrid space of SystemCL and CCL. I see 2 problems with this. Passing the TreeLogger and Context isn't compatible since one is from GeneratorCL the other from SystemCL (with some very heavy lifting this can be worked around). Afraid that super source code from CCL would be picked up before the same stuff from SystemCL(I don't see any way to get this info). Other ways might require more comprehensive changes to gwt codebase. imho this is starting to sound like one of those things that are more trouble than they are worth.

[gwt-contrib] Re: RR : Emulate JS stack traces (phase 1)
LGTM.
http://gwt-code-reviews.appspot.com/47816/diff/3008/1037
File dev/core/src/com/google/gwt/dev/js/JsStackEmulator.java (right):
http://gwt-code-reviews.appspot.com/47816/diff/3008/1037#newcode68
Line 68: private class Bootstrap extends JsVisitor {
Bootstrap took me a few minutes to figure out. I think it is
bootstrapping the visitation? If so, then something like
InstrumentAllFunctions looks more direct.
http://gwt-code-reviews.appspot.com/47816/diff/3008/1037#newcode748
Line 748: private boolean recordLineNumbers =
Boolean.getBoolean(gwt.dev.stack.recordLineNumbers);
Don't forget to change these to configuration properties, if it looks
good to you. As further motivation, if they were config properties,
then an individual GWTTestCase could turn on the extra recording just
for itself.

[gwt-contrib] Force emulated stack traces when running JUnit tests?
Should running a web-mode test case always turn on the emulated stack trace code? You would get stack traces entries like: Unknown.bx(YourClass.java:1234) regardless of which browser you're on and the type of exception, Java-derived or native. The cost is code bloat: 64k versus 108k for the CoreSuite test to have both file names and line numbers. Just line numbers costs 96k and the stack alone is 80k. The latter two cases would be more useful if JUnitShell retained the symbol maps and deobfuscated the stack trace for you, but that's an orthogonal pass. -- Bob Vawter Google Web Toolkit Team --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---

I say we assume we're going to do the second pass (where JUnitShell deobfuscates) and do the cheaper thing. --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---

Would always on mean that it generates code even for browsers that have native stack traces (i.e. FF)? Generally, as much as I hate to say it, it seems we'd want variations of the tests both with and without stack trace code, so that we don't inadvertently break one mode or the other. It is much like -draftCompile in this respect. --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
[gwt-contrib] [google-web-toolkit] r5774 commited - Temporary commit, which comments out 3 assertions I believe are flaky,...
Revision: 5774
Author: amitman...@google.com
Date: Wed Jul 22 18:24:34 2009
Log: Temporary commit, which comments out 3 assertions I believe are flaky,
to find
out how long tests take in batching mode. Will continue to investigate these
commented out assertions.
