GWT cellTable-新的行处理程序？

Question

I want to change some fields every time my cellTable content changes (new row, row change). Is there any predefined event/handler for that?

Answer 1

See if addRangeChangeHandler or addRowCountChangeHandler in HasRows meet your needs.

If by "row change" you mean a change in selected row(s), you can use SelectionChangeHandler attached to a SelectionModel.

Otherwise, you can simply call whatever method you need when you add a row or update a data provider.
