I don't think that GWT is currently well suited for doing this dynamically. It is however well suited to do this statically through a refresh of the page. I do it statically by using @eval in my css files that reference preference classes. Preference classes are selected through a theme and the theme is loaded through deferred binding in the gwt.xml file. See also: http://code.google.com/webtoolkit/doc/latest/DevGuideClientBundle.html#Runtime_substitution This mechanism works well.
However, doing it dynamically might be tricky as CssResource contains a method ensureInjected() method to inject the css in the DOM, but there doesn't exists a method to remove it (as far as I know). The generated style names are unique per CssResource sub class type (see above link). So calling ensureInjected() on the same CssResource class with another Css file from another ClientBundle will override the previous injected names (I noticed this behavior due to some bugs in a app I was building). You could do it in this way: that is a ClientBundle per theme that contains the smae CssResource with another css file, but it would be more elegant to be able to remove the first injected css. I can do this probably, but have to digg in the gwt code and write some Js code called from GWT. - Ed -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
