HeaderProvider for the TableViewer [message #550636]

This past week I was struggling to figure out how to change the table header and columns of a TableViewer. I eventually figured out how to do it, but it requires working with the Table directly which seems to go against the grain of the TableViewer and JFace in general.

It occurred to me that there should be an abstraction for this, something like a TableViewerHeaderProvider (or somethign) that is responsible for providing headers based on the input.

My question is, does something like that exist? If not, is there a reason it does not?

Thanks in advance!

Jon

Hi,

We thought about wrapping e.g. TableColumn#setText() when we created the
TableViewerColumn-API but said that its not really making a whole lot of
sense because we'd have to proxy then all methods on Table/TableColumn.
We decided JFace should not try to completely abstract a way SWT but
provide a convenience API for MVC.
