Class GeModelChangeEvent

Reported by EventListenerIf.onModelChanged after cells were edited: the row and column indices of the changed cells. The new values are already written into the area model.

Since 1.1.96 the event comes once per change – an edit, a fill (fill handle, Ctrl/⌘+D), a commit of a batch edit or TableApi.applyCellChanges – with all cells, and changes tells old and new values.

Example

override onModelChanged(evt: GeModelChangeEvent): void {
  for (const { rowIndex } of evt.cells) {
    const order = tableModel.getBodyModel().getRowByIndex(rowIndex) as Order;
    order.total = order.quantity * order.price;          // recalculate derived values
  }
  tableApi.repaint();
}
