Incubator: ScrollTable
Hello, I have been using the ScrollTable widget (com.google.gwt.gen2.table.client.ScrollTable) in the incubator and I find it very useful. I need to add a Row Header section which contains fixed columns that do not move when scrolling horizontally. 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. Thanks, Francesco --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

If SmartGWT seems slow, just disable Firebug or similar development utilities, and be sure you haven't done anything like completely disabling browser caching.

Re: RPC.encode not working
You should be able to throw your exception from anywhere on the server side
and have it appear on the client side's onFailure (if the exception
implements IsSerializable).

Hi Dean,
Are you trying to encode an exception to throw it back to the client

Re: Servlet Response formatting in IE

What am I misunderstanding about the event model?
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.

When the first 2 entries are added they are displayed like: A B With a lot of space between those 2 entries, a thing that I dont like. Later on, when I add other entries the space between them is streched and it looks okey. I set the cell padding, I set the css for the cells, but I obtain no result.

AFAIK, it is the only GWT library (excluding JS wrappers) providing ALL the following features : - containers and layouts - MVC layer - complete look and feels - rich set of widgets (including grids, drag and drop...) - form data binding - lazy rendering Using this lib, I don't have to write any line of HTML/CSS. 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 All I can suggest you is : take a week or a few days, take the latest version of the library and see if the lib can help you (for me, it does, it just saves me a lot of time).

You've expressed your opinion (more than once) so why not leave it at that. How would it appear if someone posted in response to your every post saying that Arthur is clueless? I don't believe I was insulting anyone. And while I've expressed my opinion (which many here hold), many people are new and don't know the downside of using these libraries. Or the ZK guys saying that GWT sucks in their ads that are all over the place. Everyone is entitled to an opinion by going overboard is really not necessary. You know what they say about opinions and wanting to give them... And you've gone out of your way to voice your opinion even no one asked for it. How am I going overboard? Dave Ford's comment is indicative that people appreciate hearing what the down sides are. In order for a developer to make an informed decision, they need to hear all sides and try it for themselves. Try to take a deep breath and relax when these libraries are mentioned and ignore them instead of assuming the role of GWT gatekeeper. There have been stray email questions on various third party libraries like GChart and DnD. I don't see you jump in on those threads pointing to the appropriate forum. That's the thing, if I ignore the posts that tell people to use ExtGWT, gwt-ext or SmartGWT, and no one bothers to warn them, they might end up committing substantial resources to these projects and then have to rewrite them or have them turn out poorly. For example, see this posthttp://groups.google.com/group/Google-Web-Toolkit/msg/7e3ad4486d103b94 where the developer says load times are slow (it's even slow on my new MacBook Pro). Had the developer used vanilla GWT, I doubt they would have run into those problems. The biggest problem IMHO is that people use these third party libraries and think they're using GWT. They find that it's slow and buggy and attribute it to GWT. Then GWT ends up getting a bad reputation. People who come to this mailing list need to understand that ExtGWT, gwt-ext or SmartGWT have almost nothing to do with GWT and everything to do with the JS libraries they either wrap or attempt to mimic. That way, if they decide to use these libraries, they'll understand that they're using that toolkit, and not GWT. If I see questions about other third party libraries that go unanswered, I'll point them to the appropriate mailing list (if one exists). I can't catch and respond to every post. Anyway, I'm tired of arguing this point. If you like and use gwt-ext, that's up to you. Try not to
