I have a cell in a grid which should mimic a combo-box.  Since I can't
figure a way make a pickList editable or addable (tell me if I'm missing
something), I set up a mouse-event on a fully editable cell.  Users can
single click to type in the cell or double-click to bring up a Dialog
with a grid with all the possible values.

Problem is:  if the cell is already highlighted the listener only hears
one mouseclick even if the user doubleclicks (I guess mouse clicks get
lost in the testfield).  Is there a way to set up a listener on the text
field in the cell?  Or is there a much easier way to do all this?

Here's the relevant code:
  void gridControl1_mouseClicked(MouseEvent e) {
    if (e.getClickCount() == 2) {
      coltemp = gridControl1.getSubfocus().column;
      if (coltemp == my_col.getOrdinal()) {
        //blah blah
      }}}

Thanks.
