Re: making gwtext's toolbarbutton ICON appear
Hi guys,
I'm also having the same problem. setIconCls() works on menu items,
though.
The style names I used on the invocations to setIconCls on both the
ToolbarButton and the Item (menu)
are contained in the same css file.
I hope you guys can shed light on this one.
Thanks in advance.

Re: PopupPanel Align Right
Well, once set, the position of the popup doesn't change by itself when the window is resized. Why should it? You have to listen to the "resize of window"-event and set the position of the popup manually. Don't remeber the exact code lines - but you'll find plenty of examples in this user group - just use search ;-) On 2 Apr., 01:04, WebDude wrote: > Is it possible to align a PopupPanel with the right side of the window > or the right side of a panel? > > I know that it could be done by getting the size of the window and > setting the position of the PopupPanel based on that.

Re: Help with Byte Array to PDF
Hi, You need to not use the embedded tomcat server and point the hosted mode to your real server (e.g. localhost:8080). You do this using the -noserver option passed to the GWTShell.

Re: Why not use applets?
I have to agree after many years writing applets, web start or otherwise there just a pain to get installed sometimes (perhaps due to microsoft perhaps not). Jnlp will throw different exceptions on different os's exc. For example http://www.adligo.com/#treedemo Bottom swing link, worked fine on IE, Firefox, WinXp, Mac 10, RH 8 now on Windows Vista 64 it chokes (IE and FireFox), and I could sort of care less. I think GWT is the best way to write thin client java (javascript). Google is right 'The Browser is the Platform', 'Java is the best language'. Even with some of the kinks in different compliers jvms, lack of Thread Safe sharable SimpleDateParsers exc.., it is one of the most readable and commonly understood syntaxes. Thats probably why C# (the new microsoft .net language) looks so similar. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Back & Refresh button handling
Oh, and your requirement seems like premature optimization or you need to rethink your architecture. There is no way that keeping track of a session handle should be taking up any memory on the client side. You should be using database for your persistance layer - the database should cache your most frequently used sessions for you. The approach I like is I try to keep the server stateless - all the state goes into the client with the server simply validating & storing/fetching data & a simple RPC layer for session authorization (which is just a randomly generated ID stored in the database with information needed for authorization - the session id gets passed as a cookie although the GWT gods say to not use cookies for security reasons & instead pass it directly in the RPC code) & calling the backend.

Re: Back & Refresh button handling
GWT is javascript. You can leverage all your Javascript code from the GWT framework. That being said, you're pretty much SOL on notifying the server on a page refresh. I believe, although not 100% sure, that you cannot do anything* while the page is closing (which is what happens from the perspective of Javascript). The ONLY one that can detect the client closing is the server through a heartbeat (in other words, you can only approximate - and if you're wrong you've got to handle it gracefully on the client side by informing them their session timed out). * DOM manipulation & any kind of network communication. http://www.telerik.com/help/aspnet-ajax/ajxmozillacancelrequest.html On Wed, Apr 1, 2009 at 4:58 PM, bigtruckdriver wrote: > > I do have some server-side cleanup functionality which is basically a > session expiry, but this application is going to be needing every > advantage it can get in terms of server memory, so I need this close > window cleanup to occur as well (even though it's not a guarantee that > it will work every time, as Luke mentioned). > I think the only solution here is to call some javascript outside GWT > that can detect a page refresh. > > On Mar 27, 3:58 pm, Vitali Lovich wrote: > > The way I solve this is that a timer on the server cleans up sessions > > that haven't had activity in a while. > > > > It's a little bit simpler for me since I have a stateless setup with > > the session id simply being used for authentication purposes. > > > > I think that's the most robust approach - you don't need to maintain > > complicated state information in the server.

Define a javax.sql.DataSource in GWT 1.6 RC2
My question is simple... how do I define a new DataSource (to connect to a DataBase) in Hosted Mode in the new GWT 1.6 RC2??

PopupPanel Align Right
Is it possible to align a PopupPanel with the right side of the window or the right side of a panel? I know that it could be done by getting the size of the window and setting the position of the PopupPanel based on that. However, if window is re-sized, the popup won't move with the re-size. This would be a simple "align: right" style attribute in CSS, but it gets ignored every time that I try to use it with a PopupPanel.

can inlineHTML be used to load static HTML pages?
can inlineHTML be used to load static HTML pages? I want to harness the power of HTML designing tools to generate static HTML but use GWT to load the widget. Please note that there may be some actions defined in static html. Basically my application has number of widgets some of which are coded through GWT but some of them are really snippets of static html but they too have to be interactive. Also can i embed some GWT elements within the inlineHTML if i want to? For example i can have an HTMl like some statis text and a logo some statis text and a logo once i load the static html i need to be able to change markerforgwt with any gwt element. Is that possible in GWT? Thanks in Advance.. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: A thought about GWT project structure
Well my gwt project I seperated the client and server side. The main thing that is possible if it was one project is passing objects stright to the server. So my project use json to create objects when the client ask for stuff from the server. There might be ways to have the object passing but I not sure how to do that.

Re: Back & Refresh button handling
I do have some server-side cleanup functionality which is basically a
session expiry, but this application is going to be needing every
advantage it can get in terms of server memory, so I need this close
window cleanup to occur as well (even though it's not a guarantee that
it will work every time, as Luke mentioned).
I think the only solution here is to call some javascript outside GWT
that can detect a page refresh.

A thought about GWT project structure
In GWT recommended project structure, client code and server code are placed in one project. I find this structure is not so development- friendly in practice. (GWT 1.6 has some new update to the project structure to make it more like standard WAR project, but client and server code are still in one project.) Client code will be eventually compiled to Javascript and run on web browser. Server code will run on web server. These two parts of code shouldn’t reference to each other. The only connection between them should be the RPC interface (sub-interfaces of RemoteService) and DTOs (the Java objects get transmitted between client and server). Any attempt to let your widget reference to an RPC implementation Servlet or let the Servlet reference to a widget is wrong. However, your Java compiler (not GWT compiler) can not detect this kind of error, as these Java classes are all in the same project, and they are “allowed” to reference to each other. You can’t detect the error either in hosted mode, because client and server code run in same JVM in hosted mode. You only can find out half the issue when you call GWTCompiler (Compiler in GWT 1.6) to translate the client to Javascript. I say half because GWTCompiler only shows you the toxic references from client to server, but not the other way. A solution would be to have three projects instead of one: MyProjectRpc MyProjectGwt MyProjectWeb MyProjectRpc is a GWT module. It only contains RemoteService interfaces and DTOs. It has no UI or widgets. MyProjectGwt is your client module. It inherits MyProjectRpc, and contains widgets. MyProjectGwt’s Java build path includes MyProjectRpc. MyProjectWeb is your server project. It is a standard WAR project. Your RPC implementation servlets go here. Its Java build path includes MyProjectRpc. Therefore, both MyProjectGwt and MyProjectWeb reference to MyProjectRpc only. If your widgets incidentally reference to a servlet, Eclipse (Java compiler) will tell you right away. To make above solution work, you need to configure GWTCompiler to output to MyProjectWeb instead of the default folder www. (-out argument will do the job.) You also need to run your own web server for hosted mode instead of GWT’s internal Tomcat. (Pass –noserver to GWTShell.) There may be better way to do it. Please share your idea for a better project structure.

Re: IE error can't debug!
The hosted mode browser is some hacked up version of IE6 AFAIK. I am going
to say that
even if you compile in DETAILED mode, trying to track down a problem in the
javascript code itself is pretty difficult - probably a waste of time.
Try putting logging statements in your code (either log to some textbox or
to using RPC to a server) to try and trace the execution of your program.
Since it seems its a problem in the event handling, I'd suggesting putting
those trace statements anywhere you have an event handler.

Re: What is the easier way to deploy a GWT application to Tomcat using Eclipse?
try using the jboss as tools you can download them in eclipse via "software update" maybe that link helps you http://www.jboss.org/tools/download.html after the restart of eclipse you can use another view, where you can bind the tomcat server and deploy your stuff (hot or not) anyhow, try to spend a minute on the ant, it helps you to pack it all together in a war file (like eclipse is doing it for you ) but independently from the eclipse configs ;) so every can do that for you, if your once configured the build.xml haphe phun On 1 Apr., 19:36, Fabrício Cabral wrote: > Hello all, > > I'm using Eclipse Ganymede (latest), JDK 6 update 13, Tomcat 6.0.18 > and GWT 1.5.3. > > So, I'm looking for the easier way to deploy a GWT application to Tomcat > usint Eclipse IDE.

Re: GWT + MySQL
you need at least a server for the transaction between the gui (browser) and the dbms. some uses apache.tomcat or some other java servlet/container/application server. some are using php with extjs, but never let some js on your db. try using json or rpc. if you code the access codes in plain javascript, every honk can manipulate the data, so hide them inside the serverpart ;) gwt is in java, if you are firm with that, try using tomcat (for smaller apps) cause the clustering is not that funny stuff ... later on you can distribute that on different server, with ejb or so .. but that needs some more skills... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

What is the easier way to deploy a GWT application to Tomcat using Eclipse?
Hello all, I'm using Eclipse Ganymede (latest), JDK 6 update 13, Tomcat 6.0.18 and GWT 1.5.3. So, I'm looking for the easier way to deploy a GWT application to Tomcat usint Eclipse IDE. If I use the projectCreator/applicationCreator commands, I can't do the Export -> WAR file, because Eclipse doesn't recognize the project as a Dynamic Web Project. I've tryed use the Cypal Studio 1.0 and gwt-tooling plugins but they have several bugs and don't do what I want. So, does anyone know what is the easier way to deploy a GWT application to a Tomcat 6 using Eclipse IDE?

Re: RPC Serialization
actually i dont know the differences between isserializable or serializable, but i catched, that the compilation of the whole program results errors. so i split up the client and server side in two workspaces and prepare the interfaces/service in plain for the client compilation. on the serverpacke i include the js/html stuff, to pack it into the war file. it works fine in here ;) but it needs some attention on the classes, which are doing the bridge between both project parts -.- cheers --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: IE error can't debug!
But that does not show any errors at all. When I run the hosted mode
debugger no problems show up. It only happens when I am using IE. Does
not happen in the debug host mode thing. even though alert box says it
is internet explorer.

Re: Gwt
LoadListener (or rather you should use LoadHandler from GWT 1.6
onwards) allows you to handle an onLoad event from widgets that
implement the HasLoadHandlers interface. For example, if you have an
Image widget, then you can apply a LoadHandler to perform some
functionality once the image has loaded:
Image theImg = new Image("someimage.png");
theImg.addLoadHandler(new LoadHandler(){
public onLoad(LoadEvent event){
GWT.log("Image loaded",null);
}
});

Re: IE error can't debug!
Not sure what you mean - what debugger? The proper way of debugging GWT is
to run it in hosted mode, where it's your Java code that's being executed.

Re: RPC Serialization
GWT is gonna look for serializable classes even outside the client
package???
I double checked all my classes in the project and all of them meet
the needs for serialization. I understand that i have to be as
specific as possible with RPC but i don't wanna have a bunch of
services on my project and hove to manually configure them, that's why
i'm trying to make a generic service.
Thanks for the answer Paul.

I don't know what you're problem is, but your change from
IsSerializable to Serializable does have a side-effect. When GWT
compiles your code, it now has to look for all Serializable classes to
convert to javascript, in case they get used with your code (since your
API now uses Serializable). When using IsSerializable, this is less of a
problem because you will only make classes implement IsSerializable that
will really be transported to the client, but you're probably using all
sorts of Serializable classes that will never get sent to your client,
and GWT has to sort through all of them at compile time.
It's generally better to nail your GWT RPC API down to specific classes
as much as possible. This means using ArrayList instead of List or
Collection etc for anything a GWT client accesses.

Re: Acces to GWT JavaDoc in Eclipse
Hi Stefan! You are right: I've removed gwt-servlet from the POM dependencies of the corresponding project, because I don't need it yet. If I need this I will create a separate "server/backend"- project which does. And now I have access to the JavaDoc.

Multi-module application: load module on request
Hi All, I’ve read a lot of discussions related to multi-module applications but I still don’t have a solution for my problem. In a nutshell I would like to make 2-module application in which one module is loaded immediately and the second one is loaded when user requests functionality stored in it. More detailed, I’m developing a system, which have 2 function areas, which are mostly independent from each other. Assume each area is stored in its own module. Of course they can have some common classes and functions but these could be easily moved to additional module, which will be inherited by both modules. So initially the first part is loaded when application is requested, and the second part should be loaded when user wants to access it. Now I have 3 modules: 2 are described above functional modules (without entry points) and the 3rd one is a kind of organizational module, which inherits both functional modules and has entry point. But the problem is that both functional modules are loaded during the bootstrap (and increase loading time) even when user do not need the second one. Does somebody have the same problem? Any thoughts or comments are really welcome… --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

RPC Serialization
I was using IsSerializable Interface until i read an article on gwt
home page saying that i could use the java.io.Serializable interface,
since i was using a generic servlett dispatch all my incoming
resquest, the java.io.Serializable was much easier to use, so i
changed all my classes that needed serialization and after that my
services stoped working.
All my classes are complying with the gwt-rpc serialization rules, no
error is showing up on the console or on the shell, i tried to debug
an found tha my servlet returns the dto back to then client, but gwt
somehow doesn't show any error and my code never reach then
"onSuccess" or "onFailure" method on the client side.
Here's the piece of code i'm using:
//Method on the servlet
public HashMap getValue(String serviceClass,
HashMap params)
throws DyadException {
try {
Class clazz = Class.forName(serviceClass);
DyadService classInstance =
(DyadService)clazz.newInstance();
HashMap ret =
classInstance.getValue(params);
//it gets here, but after then return call
nothing happens
return ret;
} catch (Exception e) {
DyadException ex = new DyadException();
ex.setDetailedError(e.getMessage());
throw ex;
}
}
//Class i'm sending to the client
//Used to implement the IsSerializable and worked fine
public class Navigator implements Serializable {
private static final long serialVersionUID = -318059226468181729L;
private Long id;
private Long licenseId;
private String className;
private String name;
private ArrayList submenu;
private String process;
private String cssName;
public String getClassName() {
return className;
}
public void setClassName(String className) {
this.className = className;
}
public String getProcess() {
return process;
}
public void setProcess(String process) {
this.process = process;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public ArrayList getSubmenu() {
if (submenu == null){
setSubmenu(new ArrayList());
}
return submenu;
}
public void setSubmenu(ArrayList submenu) {
this.submenu = submenu;
}
@Override
public boolean equals(Object obj) {
Navigator nav = (Navigator)obj;
return nav.getClassName().equals(this.getClassName()) &&
nav.getName().equals(this.getName());
}
public String getCssName() {
return cssName;
}
public void setCssName(String cssName) {
this.cssName = cssName;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Long getLicenseId() {
return licenseId;
}
public void setLicenseId(Long licenseId) {
this.licenseId = licenseId;
}
}
//
At this point i'm stuck, so i would really appreciate some help.
thanks in advance.

These widgets (at least the ones I looked at in 1.5, and probably 1.6 as well or they'd have fixed it) set their child widgets up while detached, so percentage sizes don't work on the children, and they use percentages for themselves, so if you nest them, they *are* the child and that is why they get screwed (if I remember correctly - it was nearly a year ago now). There are *some* situations where they will work - for example, setting up a SplitPanel in the child area of an *open* DisclosurePanel and then closing it works, but you see this actually happening, partly because some browsers are like that, but in the others too, because these panels use deferred commands. Even then, if the user closes the DP and the DP is detached from the DOM (as might well happen with tabs, or your own menu system) then when you come back, it's screwed again. There may be a way around it, but I haven't found one and the Google guys haven't mentioned one. I think we'll have to wait for V2 and hope that these widgets are rewiritten so they work if nested.

Mouse handler in GWT1.6 issue
Hi, I am working with GWT with added Plugable features like DND and ENT. Presently i am facing a problem while using the GWT Listners on the Label. As per my Understanding the GWT 1.6 Version has changed the listner handling style, which is more inline with the JavaScript Standards (Not fully but to major extent). I am using a addClickHandler for listning on the label Widget. This listner acts differently for me depending on the Mode of launch ( Internet Explorer(IE 6.0), Mozilla and in Hosted Mode of GWT) The Listners provided by the GWT 1.6 dont have the handle for Single click of mouse , double Click of the mouse so when i use the addclickHandler it is able to Caught both the action but behaves differently for both. Senario 1:- Single Click of Mouse executes the block only one (Inner Class is executed only once) Senario 2:- Double Click of Mouse Executes the Block 4 times in the Hosted Mode 2 times in the Mozilla 4 times in the Internet Explorer. As per my need i have to check if the customer has placed a single click or a double click depending on that i have to vary my business logic. So please do give some suggestions on the above query so that i can know whether the things are right in first place and if yes then how can i handle it.

Re: DatePicker and keyboard navigation?
I had at one point a version of DatePicker that had keyboard navigation built in (it'd even skip disabled dates), so it is possible. -jason On Mar 31, 2009, at 10:52 PM, nina wrote: > > Hello there > > Does anyone know if it's possible, or will be a future feature, to > have keyboard support for the DatePicker widget?

Re: Left widget of HorizontalSpliPanel is not visible
Hi,
It doesn't work. It's worse in the non-IE browsers, you can't even manually
drag the split.
A lot of the layout kind of widgets with 'moving parts' (Tab, Split,
Disclosure, StackPanel and the like) simply don't work if nested inside
another one of these kinds of panels. Google don't seem to think this is too
much of a problem.
I first tried to get a response from someone back in August last year with
v1.5 but no-one took any notice - see
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/7ca416b698acf0c8/31b434ab6d16cb39
I got no answer, and reverted my site back to 1.4.
I tested it when 1.6 came out so I wouldn't waste my time again. It still
hasn't been fixed.
It now has an issue number since I have actually managed to get a reply from
a GWT team member - see
http://code.google.com/p/google-web-toolkit/issues/detail?id=3433
If you look at it, you will see that only one person has starred it (me) so
the chances of anything happening are slim. For example, issue #25 (Sept
2006, 16 stars) has only just made it to 'Fixed, not released'.
Sumit Chandel has said this is not a show-stopper - which I take it means it
will not be fixed in this release, either.
The bottom line is that you are fd - you can't nest dynamic layout
panels - your only choices are to build them properly yourself or keep your
site so simple that you don't need to nest them.

Re: FlexTable : how to get not wrapping text functionality
Hi Rudolf,
Ok I agree with that I have the fixed width, but see below what I have
now,
FlexTable f1 = new FlexTable();
f1.setHTML(0, 0, " This is a very long
text");
f1.setBorderWidth(2);
RootPanel.get().add(f1);
Even now its is not working..
Thanks

It would help if I knew how ;-) But yes, thinking a bit more about it, isDefault wouldn't work. What would work is a "history initiated" flag. > How does it work with your definition of 'original token'? I must have missed something in your app/framework behavior... The problem is that History.getToken() can be where you come from (when setMenuByToken is called by the menu) or where you're going to (in response to history change), so you cannot use an if (History.getToken().length()==0) to condition the call to History.newItem(), or you'll never call newItem() (you pointed it already: the onModuleLoad without hash/anchor propagates down, the test evaluates to false and newItem isn't called, that's what we want, but then clicking a menu propagates down to the page and the test still evaluates to false). Hence the introduction of the isHistoryInitiated flag. 1. onModuleLoad without hash/anchor: the page is shown with isHistoryInitiated set to 'true', so in the end, History.newItem isn't called, that's what we want (URL untouched, no history entry) 2. you click on the "panels" menu which calls setMenuByToken with isHistoryInitiated==false, the #Panels~Summary page thus call History.newItem 3. you navigate back to the home using your browser's back button: onHistoryChange calls setMenuByToken with isHistoryInitiated==true, the #Home page doesn't call newItem (it does not need to, as the current history token already matches the displayed page) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: AJAX app stuck when running Selenium RC
To proof that Selenium does disrupt application execution I've modified the application so that it sends messages to the server in 1000ms intervalls. Those messages should get logged in the webserver log. Now if I open the deployed application messages appear in the log as expected. If I then fire up the Selenium tests on the very same application no such messages end up on the server! I haven't found any info whether this happened to other people as well. But I'm asking again: Has anybody had similar issues? And maybe a solution?

Re: Why not use applets?
I don't want to think of a situation where you have to install plugins to use your webapplications. Don't get me wrong, I like Adobe Flex. But doesn't run on any device (read: phone!)

Re: widgets within widgets
That's it, thanks Paul! I guess using this.button = new MyButton();
makes button a property of MyDiv so I can then use button's methods
from this class - this.button.addClickListener et.c. Is this
conceptually correct? I'm still learning OOP as you can tell! ;-)

...and note that the now-deprecated listeners have been "rewritten" on
top of this new "handlers" system, with some overhead (compensating
the removal of the XXXListenerCollections). Notably, adding a listener
creates a wrapper class and adds it as a handler for each event
handled by the listener, even if you don't handle it; and removing a
listener is quite costly (the wrapper doesn't keep a reference to the
HandlerRegistration objects, as it could potentially be added as a
handler to more than one widget –even if that's not the case when
using the now-deprecated add/removeXXXListener methods–).
In other words: if you switch to 1.6, switch to handlers at the same
time!
(and if you made your own listener interfaces, transform them to event
classes and handler interfaces)
A side effect of this new "layout" is also that it makes it possible/
easier, in composite widgets, to attach a KeyUpHandler to one child
widget and a KeyDownHandler to another child widget and, for
performance (to reduce the number of classes, see [1]), implement them
at the composite (or rather an internal class) level: onKeyUp will
only ever be called by one child widget and onKeyDown by the other.
In GWT 1.5:
class MyWidget extends Composite {
TextBox a;
TextBox b;
KeyboardListener listener = new KeyboardListener() {
public void onKeyDown(Widget sender, char keyCode, int
modifiers) {
if (sender.equals(a)) {
// a fired a "key down" event
}
}
public void onKeyPress(Widget sender, char keyCode, int
modifiers) {
// I don't need "key press" events
}
public void onKeyUp(Widget sender, char keyCode, int modifiers)
{
if (sender.equals(b)) {
// b fired a "key up" event
}
}
};
MyWidget() {
...
a.addKeyboardListener(listener);
b.addKeyboardListener(listener);
}
}
In GWT 1.6: (note that the "keypress" event is never ever sinked at
the DOM level, which also helps in improving performances a bit)
public class MyWidget extends Composite {
TextBox a;
TextBox b;
Handlers handlers = new Handlers();
MyWidget() {
...
a.addKeyDownHandler(handlers);
b.addKeyUpHandler(handlers);
}
private class Handlers implements KeyUpHandler, KeyDownHandler {
public void onKeyDown(KeyDownEvent event) {
// no need to check: a fired a "key down" event
}
public void onKeyUp(KeyUpEvent event) {
// no need to check: b fired a "key up" event
}
}
}

RPC Serializable problem
I am working on a gwt-Evaluation project and we are working with
smartgwt, our first goal was to simply make a GUI working with local
TestData. Now we are supposed to split the client code from the
TestData which should be moved to the server. So I need to make RPC
calls to get the necessary data from the server services all the time
but I have a hard time getting it to work because of non-serializable
types I guess. This is a simplyfied code example.
My user-defined Class is not serializable it seems but I can't figure
out why.

Left widget of HorizontalSpliPanel is not visible
I have created a DecoratedTabPanel with three tabs. Tab 1 and Tab 3
have some basic widgets. In the second tab I have added a
HorizontalSpliPanel to the DecoratedTabPanel. On load I want to
display the first tab by default.
I have used the following code to add the HorizontalSpliPanel :
horizontalSplitPanel.setSize("500px", "350px");
horizontalSplitPanel.setSplitPosition("30%");
horizontalSplitPanel.setRightWidget(new HTML("some text goes here");
horizontalSplitPanel.setLeftWidget(new HTML("some text goes here");
//Add widget for 1st Tab
.
//Add widget for 2nd Tab
decoratedTabPanel.add(horizontalSplitPanel, "Some Label");
//Add widget for 3rd Tab
.
However, when I click the second tab to view the Horizontal Split
Panel, the right hand side of the Horizontal Split Panel covers the
entire area and the left hand side widget is not visible. I have to
manually drag the splitter towards the right to view the contents of
the left widget. What I want is to view the left widget and the right
widget of the Horizontal Split Panel as per the size I have set.
Please help.

CSS Style for single tabs of a TabBar
Hi everyone,
i am trying to disable a few tabs in my TabBar since there is no
content in some cases. Therefor i disabled those tabs due to adding a
TabListener with the Method onBeforeTabSelected which returns false if
the tabIndex fits. (hint from this thread:
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/ceeca70295818527/65cbf68fbaff5f5b?lnk=gst&q=tab+disable#65cbf68fbaff5f5b)
. It works fine and nothing happens if you try to click on the tab.
Now i want those disabled tabs to look different than active or
selected tabs.
Example CSS file:
.MainBar .gwt-TabBar {
background-color: #22;
}
.MainBar .gwt-TabBarItem {
font-weight: bold;
cursor: pointer;
background-color: red;
}
.MainBar .gwt-TabBarItem-selected {
font-weight: bolder;
cursor: default;
background-color: green;
}
.MainBar .gwt-TabBarItem-disabled {
color: grey;
font-style: italic;
background-color: yellow;
cursor: default;
}
It works for the active and selected tabs, but i think disabled tabs
are not supported in GWT 1.5.3 that's why i have to set the style on
my own (since i only managed to disable them), but i don't know how to
access a single tab. Any suggestions? If there is a better way to
disable tabs and change the style let me know! I think with GWT 1.6 it
is possible to enable/disable single tabs, but i would like to work
with 1.5.3 until 1.6 has the status of a new official release.
Thanks a lot in advance,
-Lord-67

Re: widgets within widgets
To be even clearer, in MyDiv I added
public MyDiv (String html, ClickListener listener){
super();
setStyle();
MyButton button = new MyButton(html, listener);
button.addClickListener(listener);
this.add(button);
}
which looks legal according to MyEclipse, but produces the compile error.
FYI MyButton (which worked before I tried wrapping it) has:
public MyButton(String html, ClickListener listener) {
super(html, listener);
}
Was this what you meant Luke?

Re: Information on the GWT1.6 Compared with GWT1.5
On the surface, a Handler is just a Listener, but with only 1 event method. Event Handlers also don't have a removeOnClickHandler method, instead the add method returns a registration object that can be used to de-register that handler. Underneath, Handlers are a very different beast. All of the Handlers for a specific Widget are registered with the same HandlerManager, thus no more needs for a ClickListenerCollection and a MouseListenerCollection and a KeyboardListenerCollection, etc. The HandlerManager will also manage any Handlers and Events that you invent and want to add to the Widget. On top of that, DOM events (click, mouse, keyboard, etc) are handled specially and only sinkEvents when the related handler is added. The result of this "uniform event mechanism" is that the amount of code GWT generates is a lot less, and consumes less memory than the old Listener mechanism. More detail available on my blog: http://lemnik.wordpress.com/2009/03/04/gwts-new-event-model-handlers-in-gwt-16/ http://lemnik.wordpress.com/2009/03/12/using-event-handlers-in-gwt-16/ Hope that helps a bit. //J Ved wrote: > Hi, > > I have a query regarding the listners which are exposed by GWT1.6 API > for the widgets Comparing the same with GWT 1.5 > > I have seen a drastic change in the listner API exposed by the GWT 1.6 > for Eg: > addClickListner is not present in GWT1.6 it has addClickHandler > > > Can i know why these listeners are deprecated and what advantage i get > it from Using 1.6 rather than GWT 1.5 > > > Thanks & Regards, > Ved Prakash Kamishetty > > > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: widgets within widgets
Thanks Luke,
But actually doing that in MyDiv causes a compilation error:
cannot find symbol
symbol : method addClickListener()
location: class com.dds.gwt.widgets.client.ui.MyDiv
Just to be clear, MyButton already has listeners set up using Button's
native clicklistener so I just want MyDiv wrapper to pass a listener
to MyButton.
Thanks,
Alanj

Er, gwt-servlet does *not* include the javax.servlet classes (it's meant do be deployed in your servlet container, which already has them), use gwt-dev- for compilation and gwt-servlet only for deployment (or add your servlet.jar (or whatever its name) in the classpath in addition to gwt-servlet when compiling). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: What's the Easiest Way to Handle Server / Client Time differences?
It's a bit unclear, the problem with a day is because the difference of 4 hours? One way to manage dates, when all the users are in the same timezone, is to manage it as a String (mmdd for example). It's very clear for all developpers in the project (specially for junior ones). The best way is to use UTC (standard time) + Date objects + timezones. In this way you will not have any problem with timezones, daysavings time, etc. But all the users must have well configured it's timezone. And dates should always be used in Java and stored in the server as Dates, timestamps or an apropiate object. For some people it's difficult to work in this way because each time they debug or review some information the hour depends on the configured timezone. For example you can see one hour in the logs, another different in TOAD and another different in a TOAD in other PC, but all could be the same. It's translated to string using the local configuration of the PC your were working.

Left widget not visible in HorizontalSplitPanel
Hi,
I am trying to add a HorizontalSplitPanel to a DecoratedTabPanel. In
the DecoratedTabPanel I have set 3 tabs. I have the
HorizontalSplitPanel in my second tab. On page load I want the first
tab be displayed by default hence I have set :
decoratedTabPanel.selectTab(0);
(First tab and third tab have some basic widgets)
For the second tab i am doing this :
horizontalSplitPanel.setSize("500px", "350px");
horizontalSplitPanel.setSplitPosition("30%");
horizontalSplitPanel.setRightWidget(new HTML("some text goes here");
horizontalSplitPanel.setLeftWidget(new HTML("some text goes here");
When I click the second tab, the left widget is hidden from view. The
right widget covers the entire area. I have to drag the splitter
manually towards the right side to see the left widget.
What i really want is that both the rigth and the left widget should
be displayed as per the size I have set.
Please help.

AFAICT, compiling a given permutation isn't faster than in 1.5 but permutations are now compiled in parallel threads. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: FlexTable : how to get not wrapping text functionality
Hello Suren,
since you have a fixed width on your table then you need to wrap the text
inside another html tag so it can be wrapped.
keep the code as it is and try this
f1.setHTML(0, 0, " This is a very long
text");

Help me make my own Jar file with an interface, that can be shared between the client and a Java-based server
Hi, I am implementing a rather standard backend/frontend structure. My backend is implemented in Java. My frontend is implemented in GWT. I am using Eclipse. The frontend will be a simple viewer for "some data", that will be accessed through an interface. I would like to package this interface in a Jarfile, so the backend and frontend can share this code without creating any cut/paste/synch errors. I have created a Jar file, that contains a skeleton structure (my "hello world" of including a Jar"). It contains both the .class and .java files from the interface project). The contents are: a...@worm:~/tmp$ unzip orion-gwtresultsmodel.jar Archive: orion-gwtresultsmodel.jar creating: META-INF/ inflating: META-INF/MANIFEST.MF creating: dk/ creating: dk/ange/ creating: dk/ange/orion/ creating: dk/ange/orion/gwt/ creating: dk/ange/orion/gwt/models/ creating: dk/ange/orion/gwt/models/results/ creating: dk/ange/orion/gwt/models/results/interf/ inflating: dk/ange/orion/gwt/models/results/interf/Results.class inflating: dk/ange/orion/gwt/models/results/interf/Results.java I have put the jarfile in my GWT project (in ./lib), and added it to the Java build path in Eclipse. Now my editor can see it. Unfortunately, when I try to run the GWT project, I get this error: "Failed to load module dk.ange.orion.gwt.frontend.GwtResults. Please see the log in the development shell for details". The log reads: "Compiling java source files in module 'dk.ange.orion.gwt.frontend.GwtResults' Removing units with errors Errors in 'file:/home/asj/crypt/myShopInstall/gwtresults/dk/ange/orion/ gwt/frontend/client/GwtResults.java' Line 24: No source code is available for type dk.ange.orion.gwt.models.results.interf.Results; did you forget to include a required module?"

Re: 1.62 cannot compile my project
I have the same problem, my previous app works fine with GWT 1.53, I download the last 1.6 (current is 1.6.3 RC) and remove all warnings about Listener, I first set xmx to 1024 because 512 was not enought for my application. This solve the problem temporarily and I keep on coding. No if I add some java coding in an existing class the compiled failed with the same message, removing these lines solve the problem. These lines are not different from my usual code, the same coding is used in other classes, the objects used are already used in this class, the methods too... may be my project is too big (>300 java classes) ?

1.6 Event handlers
Hello.
I'm having some trouble understanding the new event handlers.
When creating a composite A containing widgets B and C, I want
different events from B and C to create a ValueChangeEvent on A. This
way other widgets using A can handle one event instead of two.
A - ValueChangeHandler
B - KeyUpHandler
C - ChangeHandler
What's the best way to do this?
class A extends Composite implements HasValueChangeHandlers {
private Panel container;
private TextBox B;
private ListBox C;
A() {
B.addKeyUpHandler(?);
C.addChangeHandler(?.);
container.add(B);
container.add(C);
initWidget(container);
}
public HandlerRegistration addValueChangeHandler
(ValueChangeHandler handler) { ?. };
}

GWT 1.6 - How do I change the default "war" directory name
Dear GWT community, I am considering using GWT 1.6 in a project, but have one major concern: GWT 1.6 no longer places the public files (like the host page or the module XML) in the "public" sub directory of the root package but inside a "war/module" directory. As all my projects already exist and e.g. use "WebContent" or "Web" etc. as root for the directory containing all the static content, it would be nice to reuse the existing structure. My question is therefore: Is there a way to change the default directory name "war" to something else. I would be surprised if not, but I haven't found any info in the GWT documentation pages. It would be great if someone could help me. Thanks in advance, Jan. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Is there any other easy and faster way to add text to FlexTable?
Hi All,
I am using FlexTable to populate 100 rows and each row has around 90
columns.
below is my code to acheive that..But its very time consuming. please
advise if anyother easy way to implement this also if anyother
controls I can try out other than FlexTable.
[code]
public void onSuccess(Object result) {
try {
System.out.println("Start of Movt Values");
ArrayList movData = (ArrayList) result;
System.out.println("movData.size.."+movData.size());
int currentrow = 0;
if (movData.size() > 0) {
for (int movIndex = 0; movIndex < 30; movIndex++) {//movData.size()
String rowDataObj[];
rowDataObj = new String[86];
rowDataObj = (String[])movData.get(movIndex);
//set the text in Flex Table
