Re: What am I misunderstanding about the event model?
The GWT event model is a close relation of the standard Java event model. The problem with the standard DOM EventListeners is that only one listener can be attached to an Element. The other problem is that a custom Widget may be required to listen for a sequence of low-level events in order to trigger a single high-level event (think MOUSEDOWN/UP/MOVE in relation to itemDraggedAndDropped()). So you hide the low-level events within Widget classes, which when they receive the event can trigger the collection of ClickListeners / MouseListeners / MyFancyListenerNumber3. If you are extending the classes over and over again, adding your double-click behavior to each one in it's onBrowserEvent method, you're doing it wrong. The correct way is to extend once, and allow for adding any additional listeners (double-click, keyboard, etc.) to the extended class (which should trigger them in it's onBrowserEvent method). This way the event handling logic remains separated from the Widget itself. Also bare in mind Composite style classes (like a TabPanel) that want to turn a Click event on a tab into onBeforeTabSelected and onTabSelected for it's TabListeners. Hope that helps a bit. David H. Cook wrote: The more code I implement and the more event-related APIs I look at in GWT, the more confused I get. After looking at complete examples about 'listeners' on website such as: http://examples.roughian.com/index.htm#Listeners~Summary or posts in this group, I conclude that the most general is an 'EventListener', because then I can get at ANY/ALL events that I might be interested in, as it's method gets 'Event e' as an input param. But, what seems to me like a real NEGATIVE is that I must 'extend' (sub-class) an object to use EventListener, right? Now, if I only care about a 'click', then I do NOT need to extend, because there are 'clicklisteners', which listen for just ONE event type...'click'. But, if I want, say, 'double-click', well, there are NOT any 'double-click' listeners, so it seems that I'll need to use the more general EventListener. That would be reasonable/acceptable if there was just ONE object that I wanted/needed to extend in a given app. But, let's say, I care about 'doubleclicks' from 3 different objects in the same app...anchors, tabs, and images. (Maybe not the best examples, but bear with me.) So, it seems that now I need to extend three objects, so I'll need 3 java classes (and thus, ...3 FILES...one class per file). [Some posts/examples mention 'widget builders' as a separate class of developer. But, I don't want to build new 'widgets'... I just want a write a simple app. Somehow, the APIs seem to be making things unnecessarily 'complex', when I compare this to how easy it was to implement events in javascript language (before I started using GWT). And, its beginning to seem like the designers of the event-model/event-apis in GWT might have miss-designed the APIs?! (I wasn't around at the beginning, so I don't know how the event-APIs looked in version 1.00.) Both the author of roughian website and other posters all seem to bemoan this need to extend, but all say it is necessary. For example, roughian says: [Notes: This is something you should only use if you are subclassing a widget - it's not much use otherwise, you can't addEventListener() to anything I'm aware of. So, as a builder of widgets, you'd use this to pick up events and use them in ways that you can't do with the ordinarily supported event interfaces] Clearly, I (and others?) must all be missing something.

Re: Need for a great GWT GUI library
Hi Juan, Ext GWT (aka gxt, previously MyGWT) is a full GWT solution (no wrapping JS library). It provides : - containers and layouts - MVC layer - complete look and feels - rich set of widgets (including grids, drag and drop...) - form data binding - lazy rendering Drawbacks : - bugs : as the library is young, there are some bugs, but they are quickly fixed when you post a ticket (and there are almost always workarounds when you can't wait). - slower but not slow : In hosted mode, start time will be slower than a vanilla GWT app, but I don't get any performance issue once the app is launched - GPL license or pay (it can be a drawback for people who neither can release under GPL nor can pay) I use it since April 2008 in an internal app (223 classes for the GWT side) and it saves me a lot of time.

Hi there,

As you can't override the class the only way I can think of storing
the data is to persist a collection of Strings so when the selection
is made is made do something like this:
---
onSuggestionSelected()
{
myStringCollection.add(selectedSuggestion);
}
StringBuffer buffer = new StringBuffer();
for ( String selection : myStringCollection )
{
// just add a space between each item in the collection
buffer.append(selection + );
}
myTextArea.setText(buffer.toString());

The String collection will hang around as long as the object hangs
around?! Would that solve the problem?

In fact, what I found myself doing was to change my whole design (from what I had when I first implemented it in the old javascript-model) so that I am NOT implementing DBL-CLICK, because of the need to sub-class. [I found a thread a week ago or so, where someone found that in the soon-to-be released GWT 1.60, there was some refactoring of event-stuff, and I am hoping against hope that they were ripping out ALL the event-routines, and simplifying, but of course, they aren't. The community would be in an uproar. (Except for me.!)

Actually, that is not really true. GWT Designer has a very powerful reverse engineering parser that allows it to understand most (80-90%) hand-written and refactored code. You can use the GUI layout tools to create an initial design, switch to the source view to modify it and then switch back to the design view to continue working. This is one of the features that distinguishes it (and its SWT and Sweing Designer siblings) from other GUI builders on the market that either have very limited parsers or can't parse any code at all (like NetBeans).

Widgets or not, if they're used in client code then they need to be part of a module.

Search group for struts and spring. The best answer is probably to throw away your existing JSP layer and connect new GWT UI with Spring via GWT RPC, but that is not always possible.

Re: TabPanel listeners
Yes you can. Add your tabs.
tpanel.add(new SimplePanel(),Tab 1);
tpanel.add(new SimplePanel(),Tab 2);
tpanel.add(new SimplePanel(),Tab 3);
tpanel.add(new SimplePanel(),Tab 4);
Register your TabListener. And do something similar to this in you
listener.
onTabSelected(SourcesTabEvents sender, int tabIndex) {
SimplePanel sp = (SimplePanel) tpanel.getWidget(tabIndex);
if (sp.getWidget()==null) {
switch (tabIndex) {
case 0:
sp.setWidget(new HTML(This is Tab 1));
break;
case 1:
}
}

Unfortunately JSON doesn't sound like a solution for you, and I'm

Hi Rinku, Which browser does this occur on? I think the problem you're experiencing is related to Issue #624 that Thomas mentioned above, but yours is probably an IE case where a single form panel will work through history but multiple form panels trigger the bug. I would recommend updating the issue report with your case and posting some sample code to help us reproduce to problem on our side.

Re: IDE for GWT
I use Intellij with a vim plugin running GWT in hosted mode against an installed tomcat (too much information, I know). I've tried using eclipse a few times in a general sort of way. They have very similar features, though a smaller user-base, but the user- interface in IntelliJ is so well-designed I don't spend a lot of time with eclipse. Well worth the money. Also, you need IntelliJ 8 (their newest) in order to use gwt1.5 properly (ie to handle generics). Intellij 8 does refactoring, etc., through the asynchronous interface properly.

Deploying/Packaging GWT applications that have server side components
Ok: First post to the group, so please be gentle. I've built a number of GWT applications. Up to now, they've all been 100% client side, and all are really single user apps, so compiling and deploying them hasn't been an issue. I just compile them using the ???-compile.cmd generated, package up the directory structure, and it's all good. I'm working on my first application now that needs a server side. Basically, it's still a stand alone application, I just want it to communicate with various home automation tools in my house. They all talk XML over HTTP, so I built a server side proxy to handle getting outside the sandbox. It compiles and runs fine in Eclipse, and under the ???-shell.cmd execution. But again, I'm not looking this to be anything, to the end user, but an application they run local to their machine. Both the client and the server would run on the same PC, with the server just there to proxy the XML to the various HTTP services. So here is my question. How do I deploy this? Grabbing the compiled code and just running the main.HTML brings up the client UI, but server side is borked because it's not running. Is there a bundled hosted mode I can package things up in? Am I *forced* to build/ deploy some kind of separate tomcat (or other) server? I tried to find something along these lines in the forums, but I couldn't. I apologize if this has been answered before.

Re: Deploying/Packaging GWT applications that have server side components
Yes, you have to deploy to some kind of server. Tomcat is surprisingly easy to work with...especially on Windows. Just follow the instruction at http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5s=google-web-toolkit-doc-1-5t=FAQ_PackageAppInWARFile for building a WAR file. Start Tomcat and place the WAR in the webapps directory. Tomcat will deploy it for you.

Making a request to another page
Hi all, I'm trying to do the following. As part of how I'm modeling my exception handling, I decided that to be consistent with my current Struts model - I would redirect the user to a generic error page in case of an error. Thus, any exceptions in the GWT should also be handled in the same manner. I figured I could just use the RequestBuilder to send my request along. However, I see that the problem here is that it requires a RequestCallback instance in order to make the request. I probably could fake a callback and let it pass, but I wanted to check with the experts to see if there was a more appropriate way to do this. Does this mean that there is no way of making a request/call to the server without providing a callback?

Re: Incubator: ScrollTable

widths of my column(s) to be of the same value. e.g if you're being

{
StudentColumnDefinitionString colDef =
StudentColumnDefinitionString(Col 1) {
}

I have studied the AbstractScrollTable
(com.google.gwt.gen2.table.client.AbstractScrollTable) class code
which implements most of the ScrollTable functionality and I think the
cleanest and best way to add a Row Header would be to add a
FixedWidthFlexTable that implements it, much in the same way the
existing headerTable has been implemented.
Has anyone done this before? Are there any best practices to change
the current code in the incubator (AbstractScrollTable class code
would need some substantial parts added to it)?
An abovious solution would be create my own class that extends
AbstractScrollTable, but this contains either private or protected
instance variables (for example Element absoluteElement, the widget
main DIV container), so I'd rather go for the cleanest approach
possible...
Any help and suggestions highly appreciated.

Re: Making a request to another page
RequestBuilder makes an AJAX call. It doesn't redirect the browser. use setLocation for that, which I think is in the standard GWT API someplace. Otherwise, use some JSNI to do: window.location.href = http://whatever.com/;; if you really meant to make an AJAX call: Yes, you need a callback. You don't have to put anything in it, though.

Re: What am I misunderstanding about the event model?
1) You can use something called 'anonymous inner classes'. google it.
They look something like this:
someButton.addClickListener(new ClickListener() { public void onClick
() {
/* code that runs when someButton is clicked goes here. */
}});
This does produce 2 class files, but this is an utterly irrelevant
implementation detail of the JVM. GWT doesn't even give a crap about
these; it generates JS files directly from the java sources, and the
class files are there only because some IDEs don't work well without
them, and the hosted mode debug tool needs them. Whining about this is
pointless, as its a fact of life of the JVM platform. It also seems a
bit pointless to whine about: Who cares about how many class files are
involved?
2) the web doesn't work with generic 'I want every event ever' style
event catching. You can only sign up for a few events. The ones GWT
has nice abstractions for (all the 'specific' listeners) are the ones
that work reliably and similarly on all supported GWT platforms. There
are a select few event types that are non-standard and aren't
generally available on GWT's widget (the most famous one is probably
doubleclick), and there are a few widgets that don't have an
addXListener for something they do support. EventListener and the
Event class are LOW LEVEL SUPPORT classes - you do not use them in
normal code, only in library code. They are used by GWT's own widgets.
You should use them if you're building your own widget from scratch
(but not when you're compositing them from other GWT widgets). If you
aren't doing that, then you shouldn't be using them. They aren't drop
in replacements to do 'catch all events' code.
In general, you should not use the stuff that isn't supported. If,
however, you must, then you can. This involves messing with the DOM.*
utility methods and generally means you need to know what you're
doing. Remember, GWT is a *LEAKY* abstraction. Using GWT when you
don't have a clue about how html, the dom, and javascript work, is not
a supported use case. GWT is useful because it makes web development
easier. That's a long way of saying: Tough cookies, go learn how the
web works, then come back.
Once you've figured that all out, this is how you can hack GWT:
1. use DOM/Widget.sinkEvents to set up a listener on the DOM side for
the specific event you're interested in.
2. Use the EventListener raw interface / override onEvent from the
Widget class and check the Event code to know what just happened. The
'Event' class is a javascript/java interactivity tool, just like the
JavaScriptObject class. You are NOT supposed to do anything with it in
java code; you pass it into JSNI methods and then the JSNI code does
something with it. This interface also provides you with a few useful
parameters, such as the sending object.
3. As a general rule, using one event listener to handle events coming
from multiple objects, is bad design. Use as many anonymous inner
classes as you need, instead. This is only acceptable in certain
situations that involve arrays of 100% similar widgets (such as a blog
engine where you have a list of checkbox widgets, one for each tag,
where the tags on any given post are completely dynamic - for example,
set by the user when he wrote the post. Then it can make sense to have
just one event listener for the whole lot, and check which widget
caused the event to respond appropriately).
4. When using anonymous inner classes for event handlers with more
than one method (such as the keyboard listener which has keyUp,
keyDown, keyPress), but you only care about one of those, use the
XListenerAdapter class instead of the interface. Make sure you use the
@Override annotation on the one method you're overriding when you do
this, or bad things happen when you typo the method name
(specifically: nothing happens at all, which means you have to go on a
bug hunting spree to figure out why nothing is happening. It can take
a while to realize you typoed the method name. With an @Override in
place, the compiler will refuse to compile your code right from the
get go. Much easier to find that mistake now.)
Example situation: I have a cancel button and an ok button.
DO THIS:
cancelButton.addClickListener(new ClickListener() { public void onClick
(Widget w) {
dialog.close();
Messaging.flashWarning(Sign-up cancelled.);
}});
okButton.addClickListener(new ClickListener() { public void onClick
(Widget w) {
okButton.setEnabled(false);
dialog.showSpinner();
sendRegistrationRequest(emailBox.getText(), new
RegistrationRequestHandler() {
@Override public void requestAccepted() {
dialog.close();
Messaging.showMessage(Congratulations! You've signed up

}
@Override public void requestDenied(String reason) {
dialog.close();

up request, because + reason);

Re: Need for a great GWT GUI library
If you want a great library use ext gwt which is not the same as gwt- ext. Ext Gwt does contain some javascript but it is used for mostly performace issues. Other than that ext gwt is written in pure java. The gui widgets it has have basic and advance widgets. It is a great choice to do something that require some advance widgets. Also the library does have bugs however it is getting fixed with each version release while new features get added.

Re: Need for a great GWT GUI library
I've been using GXT (Ext-GWT) for quite some time now. While it certainly looks nice and provides a good amount of functionality lacking in GWT, there are several drawbacks. 1) It is very buggy. Bugs get fixed fairly fast, which is good, but I find myself submitting an abnormally large amount of bugs. While the developer (singular) is very responsive, passionate about his work, and friendly, the code isn't exactly up to the standards that was hoping for. 2) It is not just a set of widgets, it's a complete framework on top of GWT. Your team will have to invest time to learn it. Intermingling GWT widgets and GXT widgets is possible, but confusing IMHO. Which leads me to my next issue. 3) Documentation is still very lacking, although they're working on it... 4) There's some really iffy design decisions. a) The use of generics is not only inconsistent, but in many cases it's not even possible to use generics due to API bugs. The example I was going to post was actually just fixed in the release today. b) While the widgets look nice and performance is OK, you are forced to back the GXT components (like Grid, Tree, List) with GXT specific data model objects. If you have a simple Employee POJO, and you want to add it to a GXT Grid, you have to either wrap it in a Model or ModelData class, or you have to implement a marker interface and do a bit of trickery to get it in the Grid. The only reason for all of this is to support binding (since GWT doesn't support reflection). I would much rather have preferred a Swing like TableModel and an optional binding layer on top of it. c) The widgets look nice out of the box and customizing them slightly with CSS is pretty easy. However, if the changes require you to alter the HTML of a GXT component, you're in for a world of pain. The HTML markup is tied heavily into the functionality of the widgets and is referenced throughout the class either by tag name, tag id, or by css class. IMHO, the UI should be completely separate from the functionality of the widgets. 5) Size. The CSS itself is ~80k. On the plus side, it's nice to have a pure GWT library in which I can step into Java code (which you will have to do quite often!). The widgets look and function very nicely. It would take a lot of time and money to write many of the widgets GXT provides. If you plan on using it as is, it works fine.

Re: What am I misunderstanding about the event model?
Hi Reinier,
So are you saying I can't use EventListener to somehow implement
double/right click support in Tree widgets and convert the Event to a
TreeItem?
Moreover are you saying that double/right click support cannot be
implemented using GWT? Unless I want to start over and re-implement
widgets?
I understand what I am looking for is very Swing/desktop app centric rather
than the norm on the web. However that is exactly what I have been asked to
do.
If you had to had to have double/right click Tree widget support how could
you/I get the TreeItem the user operated on? If Google could do it for
single click I don't see why the same is not possible for other operations.
-Dave
On Mon, Dec 22, 2008 at 4:49 PM, Reinier Zwitserloot reini...@gmail.comwrote:
1) You can use something called 'anonymous inner classes'. google it.
They look something like this:
someButton.addClickListener(new ClickListener() { public void onClick
() {
/* code that runs when someButton is clicked goes here. */
}});
This does produce 2 class files, but this is an utterly irrelevant
implementation detail of the JVM. GWT doesn't even give a crap about
these; it generates JS files directly from the java sources, and the
class files are there only because some IDEs don't work well without
them, and the hosted mode debug tool needs them. Whining about this is
pointless, as its a fact of life of the JVM platform. It also seems a
bit pointless to whine about: Who cares about how many class files are
involved?
2) the web doesn't work with generic 'I want every event ever' style
event catching. You can only sign up for a few events. The ones GWT
has nice abstractions for (all the 'specific' listeners) are the ones
that work reliably and similarly on all supported GWT platforms. There
are a select few event types that are non-standard and aren't
generally available on GWT's widget (the most famous one is probably
doubleclick), and there are a few widgets that don't have an
addXListener for something they do support. EventListener and the
Event class are LOW LEVEL SUPPORT classes - you do not use them in
normal code, only in library code. They are used by GWT's own widgets.
You should use them if you're building your own widget from scratch
(but not when you're compositing them from other GWT widgets). If you
aren't doing that, then you shouldn't be using them. They aren't drop
in replacements to do 'catch all events' code.
In general, you should not use the stuff that isn't supported. If,
however, you must, then you can. This involves messing with the DOM.*
utility methods and generally means you need to know what you're
doing. Remember, GWT is a *LEAKY* abstraction. Using GWT when you
don't have a clue about how html, the dom, and javascript work, is not
a supported use case. GWT is useful because it makes web development
easier. That's a long way of saying: Tough cookies, go learn how the
web works, then come back.
Once you've figured that all out, this is how you can hack GWT:
1. use DOM/Widget.sinkEvents to set up a listener on the DOM side for
the specific event you're interested in.
2. Use the EventListener raw interface / override onEvent from the
Widget class and check the Event code to know what just happened. The
'Event' class is a javascript/java interactivity tool, just like the
JavaScriptObject class. You are NOT supposed to do anything with it in
java code; you pass it into JSNI methods and then the JSNI code does
something with it. This interface also provides you with a few useful
parameters, such as the sending object.
3. As a general rule, using one event listener to handle events coming
from multiple objects, is bad design. Use as many anonymous inner
classes as you need, instead. This is only acceptable in certain
situations that involve arrays of 100% similar widgets (such as a blog
engine where you have a list of checkbox widgets, one for each tag,
where the tags on any given post are completely dynamic - for example,
set by the user when he wrote the post. Then it can make sense to have
just one event listener for the whole lot, and check which widget
caused the event to respond appropriately).
4. When using anonymous inner classes for event handlers with more
than one method (such as the keyboard listener which has keyUp,

Re: Need for a great GWT GUI library
Yes all of the above. The LF is lacking. But what I would like to see in GWT are more 'complete' and 'extendable' widgets. For instance GWT chose to implement/support single click events in the Tree widget but did not provide any support for double click or right click support. I understand these may be secondary needs but it makes it hard to use any widget API if I can't extend it and do what I want. Another example of a need is dynamic setting of images/URL in basic widgets such as buttons, labels, menu/tree items, etc. GWT only supports a static image and I have to jump through hoops to change it. It would be nice if the Widget API supported setting the image dynamically. In my brief use of GWT I have found the API quite lacking in functionality for dynamic applications and is not easily extended. On the other hand I have found the its JS performance and RPC behavior to be very impressive. -Dave On Mon, Dec 22, 2008 at 8:40 PM, Fred Janon fja...@gmail.com wrote: I just wonder what people would like to see in a GWT library: what widgets, what features?

[gwt-contrib] Add NativePreviewEvent to replace current EventPreview system (version 4)
Reviewers: ecc, Description: The latest version of this patch introduces PopupPanel.setAlwaysAutoHide(). Unlike autoHide, alwaysAutoHide indicates that the PopupPanel should autoHide even if it isn't at the top of the stack. The only time it does not autoHide is if a modal popup is open above it. We have also gone back to NativePreviewEvent.cancel()/consume(). Both the SuggestBox and MenuBar setAlwaysAutoHide to true. However, the MenuBar overrides the event preview to handle all of its unique special cases. Please review this at http://gwt-code-reviews.appspot.com/1801 Affected files: reference/code-museum/src/com/google/gwt/museum/client/defaultmuseum/Issue1932.java reference/code-museum/src/com/google/gwt/museum/client/defaultmuseum/VisualsForDialogBox.java user/src/com/google/gwt/event/dom/client/DomEvent.java user/src/com/google/gwt/event/dom/client/HasNativeEvent.java user/src/com/google/gwt/event/shared/GwtEvent.java user/src/com/google/gwt/event/shared/HandlerManager.java user/src/com/google/gwt/user/client/DOM.java user/src/com/google/gwt/user/client/Event.java user/src/com/google/gwt/user/client/EventPreview.java user/src/com/google/gwt/user/client/ui/DialogBox.java user/src/com/google/gwt/user/client/ui/MenuBar.java user/src/com/google/gwt/user/client/ui/PopupPanel.java user/src/com/google/gwt/user/client/ui/SuggestBox.java user/test/com/google/gwt/user/UISuite.java user/test/com/google/gwt/user/client/EventTest.java user/test/com/google/gwt/user/client/ui/PopupTest.java --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
[gwt-contrib] Re: Re: [Code Review] Small Test Framework For JJS Optimizers
Scott, I was able to get rid of custom RPO. Please check the issue: http://codereview.appspot.com/11060/show PS Do you find convenient to use the codereview tool or should I send an old-fashioned patch attached? On Dec 19, 2008 11:44pm, Scott Blum sco...@google.com wrote: Mike, I took a look and I think it's a good first pass, definitely a good start! I would actually be excited about a tad bit of refactoring to allow the tests to be more surgical. I think a little bit of work on JJSCompiler could eliminate the need for a rebind oracle entirely, and I think we'd actually rather skip optimizations during initial construction in order to surgically call specific optimizers. Thoughts? On Tue, Dec 16, 2008 at 9:58 PM, Mike Aizatsky mike.aizat...@gmail.com wrote: Scott, I'm sorry I've disappeared, but I had really busy couple of months.

I can't think of a fundamental reason that compiles should be slow for small test cases. I'll be happy to take a look at JTJSC and tests as soon as you finish the refactoring. Cool, if you want, you can chime in on the patch review for that. Update, this is working its way into the 1.6 release branch. -- Regards, Mike --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
[gwt-contrib] FileUpload should implement HasChangeHandlers
Reviewers: ecc, Description: Description: The native file input element supports change events, which are very useful to automatically submit a form when the user selects a file. FileUpload should implement HasChangeHandlers to take advantage of this. Fix: FileUpload now implements HasChangeHandlers. This would have been a trivial change except... Native file upload implementations differ slightly between browsers (some have text boxes, others don't), but the change event is fired exactly when you'd expect it to be on all browsers except Opera. Opera fires the change event every time the user types a character, which is inconsistent with other browsers and with the native text box. I added an impl class that saves the last change event internally and fires it only when the input element is blurred, which is consistent with text boxes. Unfortunately, this means that if the user selects a file through the file chooser in Opera, a change event will not fire until the user blurs the file upload element. However, this is a minor difference, its perfectly reasonable, and it only affects Opera. I verified that the impl class is compiled out on other browsers. Testing: === I tested this manually on all browsers and added a code museum issue.
