Re: widgets within widgets
It sounds like you want to implement the SourcesClickEvents class.
Just implement that class, in your implementation just use
button.addClickListener().
Of course, you'll need to bump the button out of your constructor and
into scope.

Re: Connecting to site 127.0.0.1
So I've read about this issue with eclipse and the hosted browser and I've heard that if you switch focus between the development environment and the hosted browser a few times it will begin to work again. Try to click between eclipse and the hosted browser a bunch and see if that makes it responsive. -luke On Feb 15, 8:29 pm, "sunny...@gmail.com" wrote: > This one has been bugging me for a while now, and I haven't seen > anything around like this one. > > I have a Eclipse+Cypal Studio project that has grown to a reasonable > size, and while testing I still use the GWT hosted mode to run.

Re: Back & Refresh button handling
You can not rely on this event being raised before the browser is
closed. You can use the onunload="someJavascript()" on your body tag
and then some JSNI to call your google code.
Here's the problem: the event gets raised, and you start doing your
work. The window gets closed before you finish doing your work, and
your rpc never completes and the server never knows.
I'd say at best you get a 50% success rate with the window close
events :)

Re: Flash with GWT
There's not much you can do about this :) This happens for the same reason that dropdown menus burn through 'popunders' like you describe.

Re: Working with compiled js files
That's a possibility, but really not maintainable like your java code
and after the handoff takes place your java code becomes throw-away.
Another solution is to let them code in native methods.
private native void nativeMethod(String effect, Element element) /*-{
//write javascript here
}-*/;

Re: Gilead tutorial
Giliead is used to serialize hibernate objects to the client and then get them back in sync once they get back to the server.

Re: How to show waiting status in GWT web apps?
Alternatively, you may want to double-check that its fetching the data that's taking a long time (and not rendering it). Look into using IncrementalCommands to increase the apparent responsiveness of your UI. Also, look into using DeferredCommands when you need to show a spinner but it's not going to be completed at the end of an async method.

Re: Scroll to certain position
You have a few options.
You can use the ScrollPanel class, and the setScrollBarPosition
method.
Or, you can use DOM.scrollIntoView(Element e)
Good luck

Re: Trying to change the style of tabTopLeft and right on tabBars
Sorry, didn't read your question thoroughly enough.
It looks like you understand the css inheritence problem.
Why not just use
.gwt-DecoratedTabBar .tabTopRight {
}
as the CSS class? Do you have more than one tabbar this would effect?
If so, could you wrap the tabbar in a container with a css class name,
and then use:
.container .gwt-DecoratedTabBar .tabTopRight {
}
Good luck.

Re: Trying to change the style of tabTopLeft and right on tabBars
I've had mixed results with CSS inheritence (seems like sometimes IE
just doesn't listen...)
So here's the idea -
Say I have three CSS classes,
.test1 {
border:1px solid red;
}
.test2 {
background-color:blue;
}
.test1 .test2 {
font-size:16pt;
}
and the following html:
test1
test2
test3
then I would expect the following:
test1 will have a red border as it inherits the class ".test1"
test2 will have a blue background as it inherits the class ".test2"
test3 will have a red border, a blue background, AND MOST IMPORTANTLY,
font size 16pt as it inherits the class ".test1 .test2"
(note the missing comma in .test1 .test2! its intentionally gone!)

Re: Keyboard event
Remember, when flaming a forum, not to use your real email address :) You can use the DOM and event listeners to manually monitor events. Just make sure to sink the events properly. http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/DOM.html On Mar 23, 3:31 am, "nicanor.babula" wrote: > Very nice though...

Re: Best image preloading practice?
You don't necessarily even need the image to be hidden off screen in that way. You could always just set it's display:none and have it exist anywhere on the DOM - the user won't see it but the browser will still go to fetch the image. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: How do I make a pretty, easy to use button without making custom images for each one?
If you are able to use .pngs with a full alpha channel in your project (IE6 does not support them without a work-around - google 'ie6 png') you can have great success using images. If you only have a few different background colors on your site, than create a rounded corner - fill in the area that is the background with its appropriate color and leave the area that will form the face of the button transparent. Then, you can use those four rounded corners (in various colors) to round everything from buttons to containers. Simple set the background color of the button to be the color that you want it to be, and whala! Now you have buttons in any color :) To create the PrettyButton widget you can use a grid wrapped in a focus panel - just make sure to use setCellSpacing(0) and setCellPadding(0) on the grid. You can use the same method to create a PrettyCornersWidget that will take a widget as an argument, then wrap it in rounded corners.

Re: GWT increases panel size
Firefox and IE render margins/padding/borders differently. In firefox, margins padding and the border are an addition to the width of the element. In IE, they are included as part of the size of the element. When you set the width of an element in IE you are setting the total width of the element including padding/margins/ borders. When you set the width of an element in FF, you are setting the inside width of the element. Borders/padding/margins will then be added to this width. So, if you have an element with the following style: "width: 100px;padding:10px;margin:10px;border:10px solid black;": In internet explorer you will have: Total Width = 100px; Inside Area = 100px - 2*10px (margin) - 2*10px (border) - 2*10px (padding) = 40px; In firefox you will have: Total Width: 100px + 2*10px (margin) + 2*10px (border) + 2*10px (padding) = 160px; Inside Area = 100px; --~--~-~--~~~---~--~~ 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?
Those lego pieces are the special get a box of em for 20 bucks pieces

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 function
someJavaScriptFunction(){ execute JSNI here } 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=75695&topic=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.

Re: GWT RIA s ?
Arthur, Way to keep your cool against that flamer! Good, clear-headed advice. All, On our project we've integrated GWT with spring really nicely - and I'd recommend this to anybody planning on creating a large project. Makes unit testing a reality, and configuration a breeze. We've thus far avoided using any third party gwt-libs for the reasons Arthur has already mentioned. Aside from the dependencies on potentially unreliable third parties that this creates, you may not be able achieve the same level of desired functionality compare to rolling your own composites. Using just a bit of CSS and the gwt widgets, you can create your own functional widgets suited to a particular task as need. Showing some search results? Create a search result POJO and a searchResultWidget to match. It really doesn't get any easier. Because GWT so kindly works with the MVC paradigm, it's often very convenient the code the VIEW to match your MODEL (or vice versa) which is not as easy with a third-party lib. Our modest-sized project is easily a 250kb download on the landing page. If we were to add a third party lib to this, our users would not be able tolerate the (down)load times. -lukehashj On Dec 23, 12:53 am, IO wrote: > Arthur, > Arthur, > I actually find your input very helpful.

Re: What am I misunderstanding about the event model?
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! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: So I want to make a better-looking radio group...
I would suggest using a Grid instead of the HorizontalPanel - and then use grid.setCellPadding(0), grid.setCellSpacing(0) and grid.setBorderWidth(0) If at that point you still have a gap, I recommend using the firebug plugin for firefox for discovering where that extra pixel comes from.
