Adding Vertical Field Manager in blackberry tree view

Hello I 开发者_Go百科am new to Blackberry , Can any one tell me that how to add Vertical Field Manager in to Tree View?

TreeField is not designed for this. It is not a Manager, so you can't add any child fields to it. Similar to ListField the TreeField is a way to represent on UI a potentially large data structure without eating too much RAM (since in this case there is the only UI object - the TreeField).
