Grid: ProgressBar renderer in footer

I know how to set a ProgressBarRenderer for a column in the Grid widget. That is clearly documented in
The Book Of Vaadin
section 5.23.6.

How to do the same for a cell in the footer of the Grid?

You can simply use regular Vaadin components in headers and footers:


Grid.HeaderCell.setComponent


Grid.FooterCell.setComponent

This is briefly mentioned at the end of section
5.23.7
in the book.

There ought to be shortcuts in the Column API as well, like there is for setting a textual header (
Grid.Column.setHeaderCaption
). I opened
ticket 17318
