Hello,
how do I delete just a single item from a ListField?
I tried this but it doesn't work:

     public class ListCallback implements ListFieldCallback {
            public Vector listElements = new Vector();
            
   public void drawListRow(ListField list, Graphics g,  int index, int y, int w) {  
      String text = (String)listElements.elementAt(index);
      g.drawText(text, 0, y, 0, w);  
   }
      
   public Object get(ListField list, int index) {  
      return listElements.elementAt(index); 
   }     

   public int indexOfList(ListField list, String p, int s) {  
      //return listElements.getSelectedIndex();
      return listElements.indexOf(p, s);  
      
   }
      
   public int getPreferredWidth(ListField list) {  
      return Graphics.getScreenWidth();  
   }
      
   public void insert(String toInsert, int index) {  
      listElements.insertElementAt(toInsert, index);  
   }
      
   public void erase() {  
      listElements.removeAllElements();  
   }
   
   public void eraseAt(int index) {  
      listElements.removeElementAt(index);
     
   }
}

well this was just the declaration, now the code to delete the selected item:

myCallback.eraseAt(myList.getSelectedIndex());

why doesn't it work?
is there a way to delete the selected item from the list?

thank you guys in advance!

what are you trying to say ;)?

int index = myList.getSelectedindex();
myList.delete(index);
myCallback.eraseAt(index);
