JComboBox selectWithKeyChar() method should highlight not select.. How?

Question

JCombobox's selectWithKeyChar(char keyChar) selects an item (calls setSelectedItem()) if it matched with key press but how do I override this to not set the item but instead highlight (highlight as in you move your mouse over that itme) the matched item? Any tricks?
Please help. I am using jsdk.14

Answer 1

doing this override, doesn't help me.. Please correct me.
public boolean selectWithKeyChar(char keyChar) {
      int index;
      if (keySelectionManager == null) {
        keySelectionManager = createDefaultKeySelectionManager();
      index = keySelectionManager.selectionForKey(keyChar, getModel());
      if (index != -1) {
        generateItemEvent(index);
        return true;
      } else {
        return false;
    private void generateItemEvent(int index) {
      if ((index > -1) && (index < getItemCount())) {
        Object itemAtIndex = getItemAt(index);
        ItemEvent deselectItemEvent = new ItemEvent(this, ItemEvent.ITEM_STATE_CHANGED, getSelectedItem(),
            ItemEvent.DESELECTED);
        dispatchEvent(deselectItemEvent);
        ItemEvent selectItemEvent = new ItemEvent(this, ItemEvent.ITEM_STATE_CHANGED, itemAtIndex,
            ItemEvent.SELECTED);
        dispatchEvent(selectItemEvent);
    }
