Always show beginning of JTextField, while it stays selected

Question

Hello,
I have an editable JComboBox, and when I select items from it, I highlight the selected item. If the item's length is longer than the textField's width, I have the cursor pointing to the end of the text by default. I was wondering if there's a way to always show the beginning of the text, regardless of the text length, while it stays selected. I have tried setCaretPosition(0) which works, but then unhighlights the text.
Your help will be very much appreciated.

      public void actionPerformed(ActionEvent e)
        editor.setSelectedTextColor(Color.white);
        editor.setSelectionColor(Color.blue);
        //editor.selectAll();
        editor.setCaretPosition(editor.getDocument().getLength());
        editor.moveCaretPosition(0);
      }
