/**
 * TActiveEditCommandColumn class
 *
 * TActiveEditCommandColumn contains the Edit command buttons for editing data items in each row.
 *
 * TActiveEditCommandColumn will create an edit button if a cell is not in edit mode.
 * Otherwise an update button and a cancel button will be created within the cell.
 * The button captions are specified using {@link setEditText EditText},
 * {@link setUpdateText UpdateText}, and {@link setCancelText CancelText}.
 *
 * This is the active counterpart to the {@link TEditCommandColumn} control. The buttons for
 * interaction are replaced by active buttons.
 *
 * Please refer to the original documentation of the {@link TEditCommandColumn} for usage.
