                .setOnFileChooserResultListener(new KFileChooser.OnFileChooserResultListener() {
                    @Override
                    public void onResult(File fileResult) {
                        if(fileResult!=null){
                            //do your action here    
                        }
                    }

                    @Override
                    public void onCancel(File lastChoosed) {

                    }
                })
