Re: JSNI - how to reference a CSS client bundle?

var lib = @com.ruchi.bundle.client.Resource::INSTANCE;

 var style = lib.@com.ruchi.bundle.client.Resource::button()();

 var css = style.@com.ruchi.bundle.client.Button::gwtbutton()();

 

i tried this but i got class cast exception.

Why do you write: style.@com.ruchi.bundle.client.Button::gwtbutton()()  ?? 

Your style variable is not of type Button, its a MyCssResource instance. Also the gwtbutton() method is probably not defined on your Button class and I think Eclipse should have marked that red (if you use the Google Eclipse Plugin).

 

hey i want to ask you one thing more while calling we have to write button()() or button() ?

You always have to use ()(). The first parenthesis contain the parameter signature while the second parenthesis contain the actual parameters. So if you have a method that takes a String parameter it would look like myMethod(Ljava/lang/String;)(myStringInstance). Read: http://www.gwtproject.org/doc/latest/DevGuideCodingBasicsJSNI.html 

Please write steps of code to explain exactly what should i do ?

No. If you fix the Button thing I mentioned above you are already done.
