Re: UiHandler and how to do it right?
Do you have a corresponding field in your UIBinder ui.xml with the
same ui:field property?
For example, in your ui.xml you should have:
g:Button ui:field=buttonClick Me/g:Button
In the corresponding Java class you should have:
@UiField
Button button;
@UiHandler(button)
void clickButton(ClickEvent e) {
Window.alert(Hello World);
}
As Steve said, the method name on the UiHandler can be anything. The
parameter to the method determines the event being handled. As long as
your ui:field property, the variable name on the UIField, and the
quoted text on the @UiHandler annotation match everything should work
fine.

I try to get a button working using UiBinder with UiHandler.
Unfortunately the screen shows up fine but the button does not react
on any clicks. While searching for some good examples how to use the
UiHandler annotation I got confused.
The tutorial on the official gwt site says:
@UiHandler(button)
void handleClick(ClickEvent e) {
Window.alert(Hello, AJAX);}
http://code.google.com/intl/de-DE/webtoolkit/doc/latest/DevGuideUiBin...
The UiHandler Java doc point to some test code telling me:
@UiHandler({buttonClick, labelClick})
void doClick(ClickEvent event) {
eventMessage(event);
}
http://code.google.com/p/google-web-toolkit/source/browse/releases/2
Searching this group I got totaly lost, because it looks like some
implicit naming convention:
@UiHandler(lastName)
void onLastNameBlur(BlurEvent event) {
// code from UpperCase goes here}

Thanks in advance for any clarification.

Re: is there a Naming conventions of gwt?
Could you be more specific? GWT does utilize convention over configuration in several aspects. This is especially apparent in the UIBinder model where naming conventions allow you to easily associate Java elements and methods with the defined elements in your ui.xml.

Re: Is there a GWT book covering version = 2.1.1?
There does seem to be a lack of valuable GWT books covering some of the newer aspects of the language. Have you gone through all the tutorials on the main site?

Re: Conditional CSS Updates
I don't think you can do this with conditional styles. I think you'd
be better off firing an event on the event bus when they orientation
changes and just change class/style through an event handler.
On Aug 29, 12:39 am, rth rthol...@gmail.com wrote:
Hi,
I have a Conditional CSS block that calls isPortrait() at runtime and
correctly renders the right rule based on its return value. My problem
is that I cannot figure out how to get the condition to be reevaluated
in the future (e.g., when the orientation changes, I would like to
have the conditional CSS evaluated again and the page rendered with
the new CSS). My sample CSS is below.
@if (org.foo.Application.isPortrait()) {
.stats {
border: 3px solid red;
}} @else {
.stats {
border: 3px solid blue;
}
}
The docs (http://code.google.com/webtoolkit/doc/latest/
DevGuideClientBundle.html#Conditional_CSS) states that these
conditions are evaluated at runtime (which I can confirm), so I am
hoping I can somehow force the re-evaluation to happen again.
Any pointers would be greatly appreciated.

Re: RequestFactory Best Practices: How to share object between client and server
You generally shouldn't be doing this from a design standpoint. If you want to share some simple objects or utilities you could use the shared package, but beyond that would break encapsulation. If you could explain your requirements in a bit more detail I might be able to provide better assistance.

Re: Does GWT has any framework or class or something for accessibility (especially for client side )
I'm not sure what you mean exactly. Accessibility is driven much more by the content and construction of your pages. A framework cannot make assumptions about accessibility because it doesn't know what your site is trying to express. If you follow the UI Binder approach, just construct your elements in the most accessible way that fits your site (tab indexing, alt comments, descriptive links, etc).

Dynamically convert between TextBox and PasswordTextBox

Re: Dynamically convert between TextBox and PasswordTextBox
Yes you should be able to, however you are not. There is no constructor for PasswordTextBox that takes in a TextBox.

Re: HTML ids for widgets generated in a celltable
Just curious, but why do you need ID's? Xelibrety's solution should work but you should be able to add any behavior you want to the objects through GWT without the need for an ID. If you have JavaScript that needs IDs to access them, you might as well just port Xelibrety's code over the JavaScript in question.

Re: GMail like selection combobox
It's a pretty simple Widget. The checkbox itself is simply a standard check box. The event would check all if clicked and unchecked all if unchecked. The box around it is simply a div styled as a button with a click event. The click event shows the dropdown which is simply another collection of divs, each with their own click event to check the checkboxes of the appropriate type. There's nothing overly unique about the widget as a whole. Take a look at the Gmail html of the option and it should be pretty easy to build.
