Refreshing a Treeview within a modeless dialog window: How?

["Saucier, Allen - AES" <Allen Saucier itt com>]

Hi all.  I'm struggling with gtkmm treeview refreshing on linux (CentOS 4).

Would someone be so kind as to tell me how to refresh a treeview in a dialog window that is popped up w/ the show() command?
here is my code that is called every few seconds but the "update" only appears AFTER I move my mouse.  This is driving me
crazy.

What I've commented out doesn't do the trick.

Thanks so much!  I really appreciate your help.

void CEntitiesDisplayControls::m_vUpdateAirEntity(std::string &p_sName,
  double p_dPosX, double p_dPosY, double p_dPosZ, double p_dDistance)
{
  //1st: search all rows for this entity name
  std::string s3;
  Gtk::TreeModel::Children  allRows = m_trstTreeviewModel->children();
  Gtk::TreeModel::Children::iterator itrAllRows = allRows.begin();
  for(; itrAllRows!=allRows.end(); ++itrAllRows)
  {
    Gtk::TreeModel::Row row = *itrAllRows;
    Gtk::TreeModel::Children allSubRows= row.children();
    for (Gtk::TreeModel::Children::iterator itrSubRow=allSubRows.begin();
      itrSubRow != allSubRows.end(); ++itrSubRow)
    {
      Gtk::TreeModel::Row subRow = *itrSubRow;
      if ( (s3=subRow[m_cModelColumns.m_colName]) == p_sName)
      {
        subRow[m_cModelColumns.m_colPosX] = CUtilityFuncs::m_strDoubleToString(p_dPosX, CUtilityFuncs::g_iFIXED_NOTATION, 3);
        subRow[m_cModelColumns.m_colPosY] = CUtilityFuncs::m_strDoubleToString(p_dPosY, CUtilityFuncs::g_iFIXED_NOTATION, 3);
        subRow[m_cModelColumns.m_colPosZ] = CUtilityFuncs::m_strDoubleToString(p_dPosZ, CUtilityFuncs::g_iFIXED_NOTATION, 3);
//        subRow->set_value(m_cModelColumns.m_colPosX, CUtilityFuncs::m_strDoubleToString(p_dPosX, CUtilityFuncs::g_iFIXED_NOTATION, 3));
//        Gtk::TreeModel::Path p=m_trstTreeviewModel->get_path(itrSubRow);
//        m_trstTreeviewModel->row_changed(p, itrSubRow);
//        m_vUpdateGUI();
      }// if found matching air entity name
    } // for itrRowChildren
  } // for itr
} // m_vUpdateAirEntity
