如何將ScrollBar設置爲Blackberry的VerticalFieldManager？

Question

我使用這個代碼來設置滾動條的VerticalFieldManager在黑莓

VerticalFieldManager temp2=new VerticalFieldManager(VerticalFieldManager.VERTICAL_SCROLL); 
    LabelField result=new LabelField("Result \n Result\n Result\n Result \n Result\n"); 
    temp2.add(result); 

將labelField，並將該內容由VerticalFieldManager顯示的是沒有得到scrolled.Is我的代碼是正確的嗎？。如果任何人有任何想法來處理這個請幫助我。

1. Set VerticalFieldManager style to VERTICAL_SCROLL|VERTICAL_SCROLLBAR  
2. Add a new NullField(Field.FOCUSABLE) after LabelField

我的解決辦法：

VerticalFieldManager temp2=new VerticalFieldManager(Manager.VERTICAL_SCROLL); 
LabelField result=new LabelField("Result \n Result\n Result\n Result \n Result\n",FOCUSABLE); 
temp2.add(result); 
VerticalFieldManager temp=new VerticalFieldManager(); 
temp.add(temp2); 
add(temp);
