Re: Suggestions for improving GWT group
Isaac Truett schrieb: If you want a newsgroup, why don't you go start a newsgroup? Actually there is no need to. There is already a hierarchy present that covers GWT: comp.lang.java.* Also there are other groups available e.g. in Germany (de.comp.lang.java) where GWT-questions could be answered. There are plenty of mediums for information about GWT that aren't maintained by Google. No reason you can't create another one. If there is enough traffic in one or more of the above mentioned groups, it shouldn't be a problem asking for the creation of another group e.g. comp.lang.java.gwt. The advantage of moving to a newsgroup would be that discussions about e.g. GWT-ext or how do I create a servlet are not automatically off topic or can be redirected into another newsgroup that covers that topic. Personally I don't have a problem with this group I just don't see a way to improve the group by introducing tags, experience- level-informations or votes to the system because the advanced users I assume are using the group as maillist anyway (where you will never see the last two informations) and tags don't work for most of the posts you see in this group asked by people who are new to the group (it has been tried in enough newsgroups I'm subscribed to without helping anything). Maybe it would be start to actively redirect questions to one of the beforementioned groups instead of answering them here.

Re: Need for a great GWT GUI library
GWT-Ext (http://code.google.com/p/gwt-ext/) looked very promising. I downloaded it to try it out. However it needs ExtJS and thats where all the licensing troubles came to light. In the end, it looks like you can get a version of the dependent javascript library somehow. But with all the issues surrounding it, I wasn't sure what the future of it was. I finally gave up with these libraries and am sticking to core GWT widgets for now. Unless I absolutely have to have a component from one of these libraries, I won't be looking for one. They all have their quirks or programming models that you need to understand to use them effectively. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: What am I misunderstanding about the event model?
Reinier -
Thank you, thank you, for the EXCELLENT explanation in
your posts to this thread. I totally get it now.
I like especially that you point out that, given GWT objectives
and constraints, it is NOT necessarily the right tool for
all webapps.
I guess I made the correct decision, back when I finally just
changed my design to use the GWT APIs in a straight-forward
way (rather than 'hack' down in and expose leaks.
Now I get your earlier reference to 'LEAKY'.
One last thing someone could do is to PUBLISH this sort of
perspective...i.e. put it in overview docs where new prospective
developers are apt to find it.
Cheers...

As I said, Event is a low level class. You don't use it from java
code, you use it from JSNI code. Another low level 'class' is the DOM
class. It is a repository of loads of static utility methods (you
don't ever do 'new DOM()', you just call DOM.someMethod()). Anything
you can do with Event objects without resorting to JSNI is done with
the various methods in the DOM class that start with 'event'. For
example, to get the thing that the event happened for, you use
DOM.eventGetTarget(Event e). However, this returns an Element, which
is another low level class. Elements, just like Events and
JavaScriptObjects, don't have any useful methods for java GWT code.
They are plenty useful when transported to JSNI methods, and there are
plenty of methods in the DOM class that work on Elements. Generally,
widgets CONTAIN an Element, so its not easy to go from Element to the
widget it belongs to, which is why you're having so much trouble.
Screwing about with DOM and Element will result in GWT projects that
leak memory, especially on IE, unless you -really- know what you are
doing. For example, if you add a listener yourself, you have to be
very careful in removing it at the right time or the listener, and in
turn every object it points at (and every object those objects point
at, etcetera) are stuck in the browser forever (well, until the user
closes the browser or the window with your app in it, but for a
webapp, that's what 'forever' means, really).

To implement this functionality I would use a little bit of JSNI and
the onContextMenu functionality.
Open up your module's main .html file and locate your body element.
Add onContextMenu='someJavaScriptFunction()' to it.
Next, add a script type='text/javascript'function
someJavaScriptFunction(){ execute JSNI here }/script to the inner
HTML of the head element and you are set!
If you've not read about JSNI, here is a good resource:
http://code.google.com/support/bin/answer.py?answer=75695topic=10213
Obviously, this is a global solution - usually used to display an
alternate context menu. If you're trying to implement right-click for
a particular element that's a little bit more tricky and less reliable
across browsers.

If you want the double-click event, create a DoubleClickEventListener
that extends ClickListener. When the click event is fired a timer is
started - if they click again before the timer executes, the
onDoubleClick event fires. Otherwise, it's just treated as a single
click. Using this mechanism, you can adjust the speed at which the
user must double-click for you to get the event. This can be helpful
in improving your websites accessibility (ease of navigation, etc).
This also allows you to add a DoubleClickListener to any class that
implements the SourcesClickEvents class.
If you are rolling your own horizontal/vertical panels you're
approaching composition from the completely wrong direction.
You should probably create a class that extends Composite but includes
all the functionality that you would have added to the base GWT class
(es) and calls initWidget(on a horizontalPanel). Or, simply extend the
GWT class and add the missing/desired functionality to it.
The GWT widget/event classes are like legos - use the small parts to
build a greater cohesive structure. Don't plan on the legos coming out
of the box preassembled!
IllegalStateException (onDetach) in Internet Explorer 6 and 7
Hello.
We have detected that our web application throws this Exception
sometimes:
java.lang.IllegalStateException: Should only call onDetach when the
widget is attached to the browser's document
We detect these exceptions because we have implemented a custom
exception handler that reports exceptions from the browser to our
server (code at the end).
The problem is that although this happens quite frequently (we see
this in our logs), we do not know how to reproduce it. According to
the logs timing it seems to happen (at least some of the times) when
leaving the page that contains the GWT app. But we are not completely
sure about this.
Any idea about what could be happening, about the possible root cause,
or how to try to debug/fix it, etc. ?
Any help is appreciated.
More information:
- Exception is only thrown from IE6 and IE7 browsers
- This did not happen with GWT version 1.4.62. It started happening
the same day we migrated to 1.5.3
- The widget that throws the exception is an HTMLPanel. Its parent is
a Composite.
In case you are interested, this is the site with the error (the GWT
app is the flight results page):
http://www.trabber.com
/* Code to report exceptions to the server */
if (GWT.isScript()) {
GWT.setUncaughtExceptionHandler(new
GWT.UncaughtExceptionHandler() {
public void onUncaughtException(Throwable th) {
CommonService.App.getInstance().reportException
(th, myCallback);
}
});
}

So just by extendingExceptionit would work.

Quite the contrary, actually. I started off with a customexception
which was merely a child class ofExceptionthat I intended to use in
RPC calls (i.e. service methods throw it). This actually didn't work
in the ways expected, i.e. when the server threw theexceptionI was
unable to retrieve theexceptionmessage in the client, or find out
what the cause was. Which is when some digging around revealed that if
you want to send theexceptionover the wire, it has to be a GWT
SerializableException.
This is with 1.4.6x, of course this may have changed in 1.5.x, I am
not sure.

Problem with non-english characters
Hi, im new to GWT and im having problems in displaying non-english characters. For example, im creating this menu bar and one of its items' name has the spanish accent symbol over the o letter: menu.addItem(Presentación, menuPresentacion); The ó is displayed like a weird question mark inside a box when i compile the project and load the html into firefox. So what i do next is adding a meta statement into the html file that is being load into the project. meta http-equiv=Content-Type content=text/html; charset=UTF-8 This doesnt work either, get the same result. So next I try to convert inside the java code every string into UTF-8 charset using URL methods: menu.addItem(URL.encode(Presentación), menuPresentacion); And now firefox shows it like this: Presentaci%EF%BF%BDn I also tried writting the strings inside the java code using HTML notation for special characters: menu.addItem(Presentacioacute;n, menuPresentacion); Doesnt work either.What is wrong whith this?

Re: Announcing GWT 1.5.3
I got this worked out using apache's reverse proxy module.
Workstation -- apache proxy --- (rpc call?)
(192.168.2.2) |-- yes -- ejb server
|-- no -- workstation port
Basically, you just need to set up mod_proxy like this:
===
httpd.conf
==
ProxyRequests Off
Proxy *
Order deny,allow
Deny from all
allow from 192.168
/Proxy
ProxyPass /mywebmodule/gwt-rpc-service
http://ejbserver.com/mywebmodule/gwt-rpc-service
ProxyPassReverse /mywebmodule/gwt-rpc-service
http://ejbserver.com/mywebmodule/gwt-rpc-service
ProxyPass /com.mygwtapp.UIModule http://192.168.2.2:/com.mygwtapp.UIModule
ProxyPassReverse /com.mygwtapp.UIModule
http://192.168.2.2:/com.mygwtapp.UIModule
Please note that 192.168.2.2 is my workstation where I develop the
code. Thus, when I
start hosted mode in that box, the tomcat instance will listen to port
of my
workstation. Thus, this proxy server will contact the tomcat in my
workstation for
any queries that has /com.mygwtapp.UIModule in its path, and will
contact my real EJB
server, when the hosted mode browser does rpc call.
This way, it is clean, the proxy server separate the calls for you.
Here is my hosted mode batch file:
@java -Xmx512M -cp
%~dp0\src;%~dp0\bin;C:/javadev/lib/gwt-windows/gwt-user.jar;N:/

Re: same-origin security restriction
I got this worked out using apache's reverse proxy module. Workstation -- apache proxy --- (rpc call?) (192.168.2.2) |-- yes -- ejb server |-- no -- workstation port Basically, you just need to set up mod_proxy like this: === httpd.conf == ProxyRequests Off Proxy * Order deny,allow Deny from all allow from 192.168 /Proxy ProxyPass /mywebmodule/gwt-rpc-service http://ejbserver.com/mywebmodule/gwt-rpc-service ProxyPassReverse /mywebmodule/gwt-rpc-service http://ejbserver.com/mywebmodule/gwt-rpc-service ProxyPass /com.mygwtapp.UIModule http://192.168.2.2:/com.mygwtapp.UIModule ProxyPassReverse /com.mygwtapp.UIModule http://192.168.2.2:/com.mygwtapp.UIModule Please note that 192.168.2.2 is my workstation where I develop the code. Thus, when I start hosted mode in that box, the tomcat instance will listen to port of my workstation. Thus, this proxy server will contact the tomcat in my workstation for any queries that has / com.mygwtapp.UIModule in its path, and will contact my real EJB server, when the hosted mode browser does rpc call. This way, it is clean, the proxy server separate the calls for you. Here is my hosted mode batch file: @java -Xmx512M -cp %~dp0\src;%~dp0\bin;C:/javadev/lib/gwt-windows/gwt- user.jar;N:/javadev/lib/gwt-maps.jar;C:/javadev/lib/gwt-windows/gwt- dev-windows.jar com.google.gwt.dev.GWTShell -out %~dp0\www %* http://theproxyserver/com.mygwtapp.UIModule/UIModule.html -whitelist ^http[:][/][/]theproxyserver On Nov 25, 4:12 pm, Brian hibr...@gmail.com wrote: Created issue 3131: (and 13's my lucky number... so close sorta..) http://code.google.com/p/google-web-toolkit/issues/detail?id=3131 Please star it :-) On Nov 24, 11:13 am, Brian hibr...@gmail.com wrote: How did I miss this thread?

re-drawing Popup Panel in IE
Hello!
I perform several long computations on the client, and I show a small
notification window like this:
// sample code
for( int step = 0; step 5; step++ ) {
DecoratedPopupPanel dpp = new DecoratedPopupPanel( false, true );
dpp.add( new HTML( step + Integer.toString(step) ));
dpp.show();
do_job( step ); // 1-2 seconds
dpp.hide();
}
In FF, all five steps are shown visually; in IE, the first message is
shown until the whole loop is finished.
Is there a way to re-draw the popup panel in IE without breaking the
flow of the program through timers?
Thanks!

Re: Problem with non-english characters

Is the source saved as UTF-8 and do you tell the java-compiler that the encoding to be used is UTF-8? So next I try to convert inside the java code every string into UTF-8 charset using URL methods: menu.addItem(URL.encode(Presentación), menuPresentacion); And now firefox shows it like this: Presentaci%EF%BF%BDn Reason is that the String you pass to the method is encoded by the underlying system so the % is encoded in a way that the character is shown.

how to gwt + kawa
Does anybody knows howto use kawa in gwt host mode? in the External tomcat,after configure following the guide http://www.gnu.org/software/kawa/server/auto-servlet.html, kawa works just fine, but in host mode, I do not know where to put the +default + or other relative file. I have tried to put them in the public folder,inside tomcat ROOT folder,etc, but it just does't work. Can anybody help me to resolve this?
