make link invisible via onclick

Hi,

is there a possibility to make a link invisible itself via onClick?
At the moment I get an error "The local variable link may not have been
initialized".

code:
----------------------
        final Link link = new Link( "test" ) {
        	
            @Override
            public void onClick() {
            	      link.setVisible( false );
            }
        };
----------------------

Thanks in advance.

Hi,

How about something like this.

private Boolean isLinkVisible = true ;
...


final Link link = new Link("test"){

      @Override
     public void onClick(){
          isLinkVisible = false ;
    }

    @Override
    public void isVisible(){
       return isLinkVisible ;
    }

}

Kind regards.

Josh

Sure: Just use "this" instead of "link", since "this" in the onClick() will be the anonymous object based on Link.
