In RWT radio-buttons of the same Group behave differently regarding the selection event handling than in SWT. In SWT both buttons the one that gets selected and the one that gets unselected notify their attached selection listeners. In RWT only that one that gets selected notifies the attached selection listeners. Snippet to reproduce:

    Display display = new Display();
    Shell shell = new Shell( display, SWT.NONE );
    shell.setLayout( new FillLayout( SWT.VERTICAL ) );
    
    SelectionAdapter listener = new SelectionAdapter() {
      public void widgetSelected( final SelectionEvent evt ) {
        Button button = ( Button )evt.widget;
        String text = button.getText();
        System.out.println( text + " is selected: " + button.getSelection() );
      }
    };
    
    Button radio1 = new Button( shell, SWT.RADIO );
    radio1.setText( "button1" );
    radio1.addSelectionListener( listener );

    Button radio2 = new Button( shell, SWT.RADIO );
    radio2.setText( "button2" );
    radio2.addSelectionListener( listener );

    Button radio3 = new Button( shell, SWT.RADIO );
    radio3.setText( "button3" );
    radio3.addSelectionListener( listener );
    
    shell.setSize( 200, 200 );
    shell.open();
    
    while( !shell.isDisposed() ) {
      if( !display.readAndDispatch() ) {
        display.sleep();
      }
    }
