296 | // startTimeText + stopTimeText will take only 2 (as if empty the other griddata of 1 will get ignored). | |
297 | // StopTime will then take over the missing space; I want to align "stopTime" right on the end of canvas, so | |
298 | // the added space to stop time would make it being aligned improperly | |

302 | // |SelectionCanvas SelectionCanvas|NbEventText| | |
