Re: can DialogBox has a "x" close button in the upper right hand corner like most window have?

if the source checked out is not wrong, I see the following

public static class CaptionImpl extends HTML implements Caption {

    public CaptionImpl() {
      super();
      setStyleName("Caption");
    }
  }

in class DialogBox source file,
but

com.google.gwt.user.client.ui.DialogBox.Caption has the following interface

addMouseDownHandler,addMouseUpHandler,addMouseOutHandler,addMouseOverHandler
addMouseMoveHandler,fireEvent, getHTML, setHTML, getText, setText,
setHTML, asWidget

so how could the com.google.gwt.user.client.ui.DialogBox.CaptionImpl implement Caption Inteface???

Yes, that would be exactly how you'd do it.  There's really not much to actually implement. All of the handler methods are just simple variants of "addHandler", so you really end up with having to actually write are the get/set HTML/Text methods.

I think I need create a class that implements DialogBox.Caption and then use the constructor
DialogBox(DialogBox.Caption captionWidget)
?
but the difficulty is how to implement all the method in the interface DialogBox.Caption?
let said I name the class customCaption and implements all the interface method in DialogBox.Caption and then inside the customCaption class I use flextable to add a "x" image in a column of flextable?
