and the Label widget do not have a "name" attribute too,why??????

[Gal Dolber]

The HTML widget is implemented with a div.. so there's no reason to set a name...

 

If you still want to set the name attribute to it: htmlWidget.getElement().setAttribute("name", "SomeName");

can you more clearly?

Let me rephrase: why do you want it to have a name? what would you use it for? what problem are you trying to solve?

(and this is a general comment as to all your questions here; you're sort-of spamming the group with questions which you obviously didn't even try to answer by yourself; state the problem you're trying to solve, what you tried and didn't work, what you found that didn't match; when you show people that you put a minimum of effort, then they'll be inclined to answer, possibly after doing some research themselves)

[wahaha]

it is very simple reason.i want add a "name" attribute to the "Lable"
tag,and then write css rules for the tag in ui.xml

[Thomas Broyer]

"name" won't help for CSS.

See http://code.google.com/webtoolkit/doc/latest/DevGuideUiBinder.html#Hello_Stylish_World

<ui:style>

.myLabel {

coor: red;

}

</ui:style>

...

<g:Label addStyleNames="{style.myLabel}">foo</g:Label>

[wahaha]

if "name" wont help for css as you say,then what is the substitute for
the "id" attribute in html?

Nothing. Use CSS classes. What's wrong with them?

[wahaha]

nothing wrong,but if there is just one widget need to be styled
alonely,we use css classes,it does not in accordance with the
principles of html designing.

GWT cannot know how many instances of your component you'll instantiate in the lifetime of your application, so it doesn't make it easy to give widgets an ID. It's still possible though (myWidget.getElement().setId("myId"), which supposes you know what you're doing).
