Re: GWT best Practices - JS Library Wrappers & Overlay Types
I'm going over the following pages carefully: http://code.google.com/docreader/#p=gwt-google-apis&s=gwt-google-apis&t=Overview Some GWT APIs, such as the Maps API, already have an implementation of the AjaxLoader for loading Google JS libraries, so that's one less thing to do.

Re: Inserting header and footer into DecoratorPanel
Hi Hez,
So, the top of the DecoratorPanel is one colour and the bottom
another? Couldn't you have an image in the css for the vertical
borders that faded between the two colours (though that might not look
so good as the panel increases in height)?

Re: Absolute positioning relative to other widgets
Hi Stephen, I feel this is just one of those challenging areas in
GWT. There's no "event" in GWT that tells you DOM has finished layout
activities, but there is a point where you expect this to be the case
in the normal lifecycle of a widget.
In the Widget lifecycle there are four key points you can override
that in a way act as "events":
* onAttach() - called when a widget is attached to the browser's
document.
* onLoad() - called immediately after a widget becomes attached to
the browser's document.
* onUnload() - called immediately before a widget will be detached
from the browser's document.
* onDetach() - called when a widget is detached from the browser's
document
The one of interest here is onLoad(), where it's fairly safe to assume
that everything DOM attribute wise is sorted out by then. I've still
found it wise to give the browser some time by wrapping any dimension
stuff in a DeferredCommand within the onLoad() method; I'm not 100%
convinced it is necessary, but I like to live on the safe side in an
effect library I'm building (http://code.google.com/p/gwt-fx/).
I have to admit, I'm not aware of a onResize() method to override in
Widget or Composite class, so can't really comment on how that would
work (out of interest, where is it in standard GWT?).
DeferredCommand itself is a little bit of a trick, although it says
"allows you to execute code after all currently pending event handlers
have completed" it's really based on timers rather than hooking into
the browser event queue and checking all is done before firing your
command - that said, it works.
Hope that gives you a bit more info.

GWT 1.6.4: .../war/WEB-INF/classes/log4j.properties trashed by Eclipse build
I'd like to put the file .../war/WEB-INF/classes/log4j.properties into my build, but it looks as if either the GWT 1.6.4 compiler or Eclipse wipes out the entire classes directory as a side effect of the build (when I launch the app under Eclipse). That is, I put log4j.properties into .../war/WEB-INF/classes, but when I launch the app from Eclipse, the file magically disappears. I'm guessing that something is throwing away the entire classes directory during the rebuild. Is there any way for me either to get a properties file onto the classpath inside the war? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Justification of images, how?
Hi Anders
Here is the code to display an image at the bottom right of the panel:

Image logo = new Image("images/logo.png");
HorizontalPanel panel = new HorizontalPanel();
// always good to set the border to see the panel size

Re: Absolute positioning relative to other widgets
First of all, Thank You Adam. This is one of those things that I spent
like 4 hours on and finally just asked about.
I put my absolute positioning code inside a DefferedCommand. Have not
seen it fail yet. So thank you, it seems to work.
Still, I do wonder. What is the deterministically appropriate way to
deal with this? For all I know the DefferedCommand may be the
appropriate way to deal with this, as it may truly guarantee that code
is not run till after all other events are run. Assuming that
"repositioning stuff as things are added to the DOM" is just another
event, then as long as DefferedCommand always guarantees that it will
add to the end, then it is probably correct.
However, is there some more direct way to do this. Like, could I wrap
a widget in something (or override some handler) such that I can
guarantee execution of code only after the widget has been fully
positioned and their currently exist not other DOM modifying events in
the queue?
Also, in closing, is there more information somewhere on exactly how
widgets are added, positioned, and rendered. I would also be
interested in any callbacks (or equivalent) that I can override at any
point in said process. Thanks all.

database backend best practice
I'm about to start a new application using GWT 1.6. I have a lot of programming experience, but very little with java. In my application I want to load a dozen or so different record types from a mysql database, send them to the client where the user can display/modify them in various ways, then send the data back to the database. I've looked over the basic DynaTable example and some jdbc examples and I've also read some about Hibernate. I'm trying to determine if Hibernate is worth the extra setup and configuration, vs a direct jdbc approach. Or is there a better solution I'm missing? If you were starting a new database GWT app with 1.6 what would be the best approach? Where "best" means both easiest to configure and easiest to deal with the code. Thanks for any suggestions, especially pointers to 1.6 tutorials. -- Chris --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

GWT 1.6.4 jsni doesn't like spaces in the signature
In case anyone else is having problems with the "Expected a valid parameter type signature in JSNI method reference" error after moving from 1.4 to 1.6.4 here is a possible solution: It appears that spaces are no longer allowed in the signature. For example this works in 1.4, but not in 1.6.4: $wnd.function1 = th...@com.example.test::function1( Ljava/lang/ String; ); Any spaces must be removed from the signature: $wnd.function1 = th...@com.example.test::function1(Ljava/lang/ String;); Not that I care about having to have spaces in the signature, it was just out of habit that I added them when I first built the code in gwt 1.4. The result was a bunch of time spent trying to figure out what was wrong. Hope this helps someone else. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: build.xml for Netbeans and GWT 1.6
Well, I got stung by http://code.google.com/p/google-web-toolkit/issues/detail?id=3491 and updated the build.xml file accordingly to use Java 5. I was able to update the compiler entrance class, but I still have to use 'com.google.gwt.dev.GWTShell' because I couldn't get 'com.google.gwt.dev.HostedMode' to work. Advise here would be appreciated. I was passing in the "war" and "module" names (like the compiler args)... but it complained that web.xml had a configuration error. My web.xml doesn't have anything unusual in it and is auto-generated from NetBeans, so should work in most Containers. == build.xml == Builds, tests, and runs the project Muckraker. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: How to use the new WAR file to deploy a simple web application.
Jamie, Thanks. Yes, I must learn about Apache Ant. GWT was forced me to learn a whole host of new things. But, learning is one of the more fasinating aspects of life.

build.xml for Netbeans and GWT 1.6
Dear all, I use NetBeans and the build.xml at the end of this post (based on one by Jason Morris from this group). This worked great for 1.5 but I hear there have been structural changes since then. Can anybody advise on what might need to be changed? I have a project that I am going to spend some time upgrading today... so expect a reply to this post if I discover anything that affects the buildfile. == build.xml == Builds, tests, and runs the project. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Adding the same widget more than once
On 1 Maj, 12:12, hezjing wrote:

Yup. Took me a while to figure out.
Now I usually use a common interface like this for all my widget-
making code:
interface WidgetProvider {
Widget createNewWidget();
}
This both ensures that I can introduce on-demand creation of objects
if I need it, and that I can create several instances configured in
identical ways by using this method, provided that it is implemented
in a sensible way.

Anders

Justification of images, how?
Hi, If I add an image to a panel, it is apparently always left-justified, no matter what horizontal justification I set the panel to use. Is there a way of doing this?

GWT's default CSS styles in standard.css
Hi Why there is no CSS style of .gwt-DecoratorPanel .middleCenter found in the gwt-user.jar, com\google\gwt\user\theme\standard\public\gwt\standard\standard.css?

Re: Inserting header and footer into DecoratorPanel
Hi Adam
Please be patience while I try my best to describe the problem :-)
Here is my code:
public void onModuleLoad() {
// create a label for header and apply a background color
Label header = new Label("Header");
header.addStyleName("header");
// create a label for footer and apply a background color
Label footer = new Label("Footer");
footer.addStyleName("footer");
DockPanel dockPanel = new DockPanel();
dockPanel.setSize("100%", "100%");
// add the header
dockPanel.add(header, DockPanel.NORTH);
dockPanel.setCellHeight(header, "5%");
// add the footer
dockPanel.add(footer, DockPanel.SOUTH);
dockPanel.setCellHeight(footer, "5%");
DecoratorPanel decoratorPanel = new DecoratorPanel();
decoratorPanel.setSize("30%", "50%");
decoratorPanel.add(dockPanel);
RootPanel root = RootPanel.get();
root.setSize("100%", "100%");
root.add(decoratorPanel);
}
You will need to add the following CSS styles in order to display the
DecoratorPanel correctly:
.gwt-DecoratorPanel .middleCenter {
height: 100%;
width: 100%;
background: #d0e4f6;
}
.header,.footer {
background: #f6ef32;
}
If we take a look at http://www.ebay.com/, the header and footer starts from
the edge of the rounded rectangle.
So the background color of the topLeft, topCenter and topRight should be the
same as the header.
Whereas the background color of the bottomLeft, bottomCenter and bottomRight
should be the same as the footer.
This can be done easily by replacing the corners and horizontal border with
the same color as the header and footer.
The problem now is the color of the middleLeft and middleRight, where the
color of the top part of these vertical borders should be the same as the
header, and the color of the bottom part should be the same as the footer.
How do we create such vertical border so that the top and bottom color are
aligned to the header (the DockPanel.NORTH) and footer (the
DockPanel.SOUTH)?
