BlackBerry - Afficher l'indicateur de mode de frappe par programme

Question

Connaissez-vous un moyen d'afficher différents programmes typing indicators à l'écran?
Je sais que je peux simplement dessiner bitmap mais je voudrais le faire universellement pour n'importe quelle version de système d'exploitation RIM.
En outre, il y a une fonction setMode(int) en 4.2.1 mais en 4.3 il est déjà dépréciée ...

Toutes les suggestions seront utiles, merci!

car il n'y a pas d'autre solution, je fait un échantillon avec provided images:

personnalisée Titre champ Code de classe:

Exemple de code d'utilisation:

class Scr extends MainScreen { 
    static final TITitleField mTitle = new TITitleField("Start"); 

    public Scr() { 
     this.setTitle(mTitle); 
    } 

    protected void makeMenu(Menu menu, int instance) { 
     super.makeMenu(menu, instance); 

     int typingIndicatorMode = mTitle.getTypingIndicatorMode(); 

     if(typingIndicatorMode != mTitle.MODE_NONE) 
     menu.add(new MenuItem("None Mode", 0, 0) { 
      public void run() { 
       mTitle.setTypingIndicatorMode(mTitle.MODE_NONE); 
      } 
     }); 

     if(typingIndicatorMode != mTitle.MODE_ALT) 
     menu.add(new MenuItem("Alt Mode", 0, 0) { 
      public void run() { 
       mTitle.setTypingIndicatorMode(mTitle.MODE_ALT); 
      } 
     }); 

     if(typingIndicatorMode != mTitle.MODE_MULTITAP) 
     menu.add(new MenuItem("Multitap Mode", 0, 0) { 
      public void run() { 
       mTitle.setTypingIndicatorMode(mTitle.MODE_MULTITAP); 
      } 
     }); 

     if(typingIndicatorMode != mTitle.MODE_NUMLOCK) 
     menu.add(new MenuItem("NumLock Mode", 0, 0) { 
      public void run() { 
       mTitle.setTypingIndicatorMode(mTitle.MODE_NUMLOCK); 
      } 
     }); 

     if(typingIndicatorMode != mTitle.MODE_SHIFT) 
     menu.add(new MenuItem("Shift Mode", 0, 0) { 
      public void run() { 
       mTitle.setTypingIndicatorMode(mTitle.MODE_SHIFT); 
      } 
     }); 
    }
