update SlidingMenu Mode from another Fragment

[cloudshooterhuman]

Hi,

I have a SettingFragment that contains options to change app language, for example when I change language to french I must set the menu to the LEFT ;setMode(SlidingMenu.LEFT), and when I change it to arabic I must set the languague to the RIGHT setMode(SlidingMenu.RIGHT).

To achieve taht I use the observer pattern as following :

    MainActivity extends FragmentActivity {

    ....
    @Override
    public void propertyChange(PropertyChangeEvent event) {
        final String mLanguge = (String) event.getNewValue();

        Log.v("Langue",mLanguge );
        MainMenuActivity.this.runOnUiThread(new Runnable() {
            @Override
            public void run() {
                if(mLanguge .equals(getResources().getString(R.string.params_arabe_key_pref)))
                    menu.setMode(SlidingMenu.RIGHT);
                else
                    menu.setMode(SlidingMenu.LEFT);

                // refresh the SlidingMenu
                menu.invalidate();
            }
        });
    }

(Note this methode is declared inside the MainActivity and it's called when the user change the app language)
