// * A window that launches a dialog containing a table with an editable cell.

// * during that time, an SWTException occurs.
// *
// * The dialog and window are both needed so that the SWT event loop continues
// * to run after the dialog is closed.  The {@link ComboBoxCellEditor} also
// * needs to be using the DROP_DOWN_ON_MOUSE_ACTIVATION style so that the
// * drop-down list is made visible as soon as the cell editor is activated.
