can we control what element will build in widget?

[wahaha]

for example,the Label widget will be compiled as a "div" element in
browser.
can we control what kind of element will be compiled in browser?
this is to say,if we are defining a widget,then can we control the
element's kind by the source code?

i hope you can understand my poor english.

[wahaha]

why there is nobody knows?

You cannot change the element a widget uses internally.

If you are looking for span implementations(instead of div) you can use: InlineLabel, InlineHTML

Otherwise you can create your own widgets, checkout the source code of HTML or Label, its not hard to do.

If you want this level of control you can use Element directly or an HTMLPanel

[wahaha]

ok,now i have the last question:
the element compiled by gwt,what will determine its type?by gwt
compiler,or the class's source code?

Look at "direct known sub classes". There is one element type for each html tag. 

If you create a custom widget (class MyWidget extends Widget) you have to call setElement(Element e) in MyWidget's constructor. This will tell the Widget which HTML element to use as its container. A GWT Label for example calls setElement(DOM.createDiv()) whereas an InlineLabel does setElement(DOM.createSpan()).
