isSelectAllEnabled in class CellEditortrue if select all is possible,
false otherwiseprotected void keyReleaseOccured(KeyEvent keyEvent)
The TextCellEditor implementation of this framework method
ignores when the RETURN key is pressed since this is handled in
handleDefaultSelection.
An exception is made for Ctrl+Enter for multi-line texts, since
a default selection event is not sent in this case.
