Deleting the contents of a GWT DataGrid Widget
Hi, Would like to know if there is a direct way to delete ALL the rows of the new DataGrid Widget -part of release GWT 2.4, or is the only way to do it is by maintaining a handle to some Collection you may have previously loaded into the Table, and then doing something like this to delete the rows: table = new DataGrid(); dataProvider= new ListDataProvider(); dataProvider.addDataDisplay(table); ... ... (And when you want to remove ALL the rows of the DataGrid, do the following?) List list= dataProvider.getList(); list.removeAll(CONTACTS); Thanks. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Appearance Pattern - ok, is there a better explanation, a tutorial, a step-by-step?
Hey, that's what static typing is for: - if you're implementing an interface, you know which methods you have to implement, and it won't compile without them. - if you're writing your own interface, you're necessarily also writing the code that calls the methods, so you're responsible for defining the methods, their name, their parameters, etc. If you want a concrete example, have a look at http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/com/google/gwt/widget/client/TextButton.java the only existing Cell-backed widget for now. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: gwt application using hibernate and postgresql
Thank you very for your answers,
i have read and tried what you have suggested me. What i have noticed is
that the main hibernate problem in gwt is that it cannot identify properly
the entities of the class while passing from the client side to the server
side. However, my entity class in my own application is never been accessed
by the client side. All the instances are being used in the server side.
Does this somehow affect the hibernate? Moreover, i have created an
application using the default hibernate approach and i have the following
error.

Appearance Pattern - ok, is there a better explanation, a tutorial, a step-by-step?
All, Ok, I've read the article at http://code.google.com/p/google-web-toolkit/wiki/CellBackedWIdgets in dealing with the Cell-backed Widgets, and I can't say I'm any better off than I was before reading it. First, the following line: getCell().setTabIndex(tabIndex); doesn't work at all - it requires a typecast. Second, I don't understand how/why the methods for the Appearance interface are chosen. Why are the methods called onHover and onUnhover as opposed to, say onMouseOver and onMouseOut, or heck, any other arbitrary names? Third, and related to that, what determines the parameters for these methods? Who/what is calling them, and how would I know, for example, that not only does the mouseover method need to be called onHover in the interface, and how would I know that it would need to be passed in a Context, and Element, and a String? Is there some sort of tutorial on this that goes step by step and uses examples? I am really lost with this. I've also read the Appearance Design Pattern article at Sencha as used with GXT, but it doesn't clarify things much more over the original.

Re: Styles broken after adding app to a website.
To be more precise: Running the app in hosted mode works perfect, but as soon as the app is embedded inside a website, all styles of the app get messed up because the websites css get applied to the gwt widgets/ panels. Now I'm searching for a way to reset the GWT widgets/panels styles after the app is loaded. My only idea is to apply the GWT css file to the RootPanel during the initialization of the app, with the intent to overwrite all previously set styles. But how can this be done? Or maybe there's a better solution... Please let me know.

Re: Tips on handling ScrollPanel in UiBuilder
You hit on why I asked. In my last app, begun well before Layout panels, UiBuilder, etc., I use the deferred command trick you describe: I'm displaying images that are generally too large for 1:1 (like 200dpi or more) and therefore must be scaled. I give the scaled image the largest possible screen area I can by drawing everything first then, using a deferred command, call my image servlet with the available width and height to get a scaled image. While this works, I was never happy with my attempts to resize the image area (or other areas) on browser resize. As I work on a new app and think about how to rewrite the older one with UiBuilder, MVP, SVG, etc., I want to improve on browser resizing. (There are lots of neat features in GWT, more all the time. If anyone is listening, I'd really like to see XPath and XSLT.)

Re: layout panel problem, invisible panels
I've also had problems when trying to put a layout panel inside of (as a child of) a non-layout panel (basic panel). I'm assuming this is what's happening when you place DockLayoutPanel inside of HeaderPanel. You can however put non-layout panels inside layout panels.

GWT SplitLayoutPanel + Velocity
I have a GWT application that renders a Velocity .vm file and displays links within its panel. The .vm displays search results after the API call is made. Whenever the search is first made the .vm file comes back as desired. But whenever you click on any of the links it looses the GWT application and displays the results without the application that first held the results. I can see how and why, but im wondering how can i maintain the .vm file within the application with each hyperlink click? As im writing this im thinking i should put it in a frame...? Maybe that might work. Either way does anyone have any suggestions? Regards, Sigma -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Calling onResize() is not sufficent, no, its really only used for being
notified that the size has changed, not for setting the size. A LayoutPanel
needs to be either added to another LayoutPanel, such as RootLayoutPanel,
or be given a size explicitly. Unfortunately HeaderPanel is not a
LayoutPanel (though it does need to be put inside one itself) so I'm not
sure the best way to do this
Just looking at how RootLayoutPanel does its business, in its onLoad()
method, it has:
@Override
protected void onLoad() {
getLayout().onAttach();
getLayout().fillParent();
}
So maybe extending LayoutPanel and doing something similar would do the
job, but really I don't know if this is a good idea or not! Your other
options would be to use a static sized header, or use a DockLayoutPanel
with a 'north' section that re-sizes itself when ever the content height
changes (you can use the 'scrollHeight' property of the container element
to measure how much height you need) but that's obviously a pretty ugly way
to do it.
I'd be interested to hear if getLayout().fillParent() does in fact work for
this, or if anyone else uses it successfully. I think you'd have to call
your custom LayoutPanel's onResize() method yourself, whenever the headers
content/size changes.. so that any child widgets that need onResize() get
notified of less/more space available. So, not much different than
re-sizing your header manually.. :(
Probably best to use a static height header if you want to save some time!

Re: layout panel problem, invisible panels
I've not used the HeaderPanel layout, but I'm wondering if the first element it finds is becoming the content and the others are getting ignored. While I've done a lot with GWT, I'm relatively new to UiBuilder. However it seems to me that, in keeping with the pattern of LayoutPanel and DockLayoutPanel, HeaderPanel should have some "special markup" like , , and (see http://code.google.com/webtoolkit/doc/latest/DevGuideUiBinder.html#Panels) I'm probably WAY OFF on this: That markup not described in the javadoc nor are you getting a runtime error. Unfortunately GWT Designer doesn't include a HeaderPanel so I can't draw one then compare it's XML. On Jan 5, 10:21 am, Rob wrote: > Hi, > > Why does this not work?

CellTable not rendering rows in production mode?
Hi there - we are experiencing an issue where a rather complex CellTable refuses to render its rows in production (compiled) mode, while working perfectly in development mode. We are using an async data provider, the table is built in a superclass and then handled in a subclass, and has a few custom cells (one accesing native DOM events)... Trivial controls (anything that can be done with "eyes + Firebug") are all OK: the async request for data is fired, the "loading" spinner renders OK, data arrives fine, spinners disappears, and then nothing. No rows, nothing. The table body HTML element simply stays empty. Since we (negligently, I admit) stopped deploying to production mode after the initial spikes, I am not able to trace back a single point in time when this started happening, and this is a big head- scratcher... I am wondering if anyone here: - has had similar issues in the past - can point us to some resources / ideas about any items we should be paying attention and that can cause behaviour differences between development and production - can give us a hint about any ways to debug / check what may be going wrong Bye and thanks, Emp -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Overlapping or overlaying images, while keeping handlers independent
Are you sure they're "inheriting" handlers? I think the mouse enters the region of both images and so their handlers are activated. If you have two images that don't completely overlap and you enter an area that isn't overlapped, only one handler is called right? Unfortunately, I think you'll have to consolidate these into a single handler and you'll have to somehow figure out the z-order of the images, then chain to the appropriate handler. I think I'd try to wrap the Image in a FocusPanel (since only one element can have focus at a time) and then use a focus handler to beat this problem ... it's probably easier than trying to recreate the logic the browser used to render the Images with the proper z-order. Good luck (and an interesting problem). smoyer -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

This is my first message to the group. I'm a contributor on a similar project at j2s.sf.net. Tried GWT some years ago and didn't like it, but now, it has improved a lot. My congrats to the authors! keep the good work. Now my question, I would like create a simple html site, with no server stuff at all, only text, images and css, in gwt. Is it possible to deploy a gwt app (with no rpc/requestfractory/server at all) as static content in a non servlet support like plain apache?

layout panel problem, invisible panels
Hi, Why does this not work? "Header top" appears, but nothing else. The divs inside the dock layout have zero height. HeaderPanel calls onResize for it's 'content' element. Is that not enough to work with LayoutPanels? If I remove the HeaderPanel, the DockLayoutPanel works as expected. I want to use HeaderPanel, because I want a top div that is sized naturally by the browser.

GWT draggable CellTable cells
I have a GWT CellTable - it's a pretty simple table with just a single string column. What I'd like to do is drag rows of this table to a drop target (actually another table). I've been trying to figure out how to attach a draggable event as described at ~23:00 of this video (http:// www.youtube.com/watch?v=KEkR1ox_K10). To which CellTable element can I set the draggable flag to TRUE. I haven't gotten this far yet, but I'm sure I'll soon face a similar issue in setting the drop handler on the target table. If someone could post an example or point me in the right direction, I'd be grateful. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT application freezes when new version is deployed while using it
If you're using Tomcat, Tomcat 7 supports updating a webapp and keeping the old instance running along side it for situations like this. As I understand it (I don't use it yet), http sessions/requests tied to the old webapp get routed to the old instance and new sessions get routed to the newly deployed one. After all the sessions are dead from the old web app it's undeployed. Obviously, this won't work for everyone since some people have issues hot deploying their app, but it's something you could look into.

Re: Tips on handling ScrollPanel in UiBuilder
Excellent. That works and is exactly what I was trying to achieve.
Thank you, Aidan.
Here's a follow-up question: When using UiBuilder, how do I implement
a panel's onResize() method? I think the answer is to assign the
panels' ui:field's in FiltersViewImpl.ui.xml and call their onResize()
in my FiltersViewImpl.java. Am I correct?
Going back to my original question, I remove height from g:ScrollPanel
in FiltersViewImpl.ui.xml. In what had been:
layoutPanel.setWidgetTopHeight(menuPanel, 0, Unit.PX,
MENUPANEL_HEIGHT, Unit.PX);
layoutPanel.setWidgetTopHeight(filtersPanel, MENUPANEL_HEIGHT,
Unit.PX, 100, Unit.PCT);
...
in MyAppViewImpl is now:
layoutPanel.setWidgetTopHeight(menuPanel, 0, Unit.PX,
MENUPANEL_HEIGHT, Unit.PX);
layoutPanel.setWidgetTopBottom(filtersPanel, MENUPANEL_HEIGHT,
Unit.PX, 0, Unit.PX);
...
(Sigh... XmForms, GridBagLayout, and now this. Makes me long for the
days when everyone had one of 3 displays and I could just draw a GUI
in ResEdit.)

Re: GWTTestCase possible issue (SmartGWT DMI call)
I should have given more background in that I do not know the exact issue from the two links posted, only that they seem to have the same error. What I was trying to do was run a GWTTestCase to test a block of code that contained an RPC call using SmartGWT's DMI RPC. The error shown in the posts is what I received when the GWTTestCase failed. I was hoping to use GWTTestCase since it allowed me to isolate and test my code directly. I was wondering is if anyone knows of a way to get this to work or at least why the error occurs. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT application freezes when new version is deployed while using it

Re: GWT application freezes when new version is deployed while using it
Maybe keeping the old *.gwt.rpc files around (provided you didn't change the remote service interfaces and transported types), or maybe it was a feature of the abandoned deRPC (ever noticed that Google Groups –which uses GWT-RPC– regularly asks you to reload the page to get the newer version? (luch more likely to happen if you keep your browser/tab open for days)). For runAsync, keeping the old fragments will do it (obviously, the users will still be running the old version, so your server should be prepared to handle calls from this version). Unless you're deploying several times a day, it's much easier to just have users reload the app: only a few users should ever notice it, and most likely when coming back to the app after they let it open in their browser during the night/lunch (of course plan your deployment depending on your app's traffic) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Don't think that's possible, but you can do the refreshing "user friendly" by simply reloading the app and pointing to the "place" where the user currently is...
