[JFace] ViewerColumn and EditingSupport [message #327927]

Is there any particular reason why ViewerColumn.getEditingSupport() is
not public or at least protected?
I've written a "builder" that builds custom TableViewerColumns using
custom EditingSupports and CellEditors. The clients of this builder
sometimes need access to the EditingSupport (my custom subclass), but
there is no easy way for them to access it because getEditingSupport()
is only package-visible.

I understand the SWT/JFace philosophy of minimalism when it comes to
API, but a public getter for something that already has a public setter
seems like a reasonable request. As it is, I have to subclass
ViewerColumn, and I can't even subclass TableViewerColumn because it is
final (argh!).

I was thinking of filing a bug about it, but maybe there is a
pre-existing reason it is the way it is...?

You will notice that ColumnViewer.getViewerColumn(int) is also not API. At
least we are consistent... ;-)

Our thinking was that you should not have to do anything with column objects
and editing support after they have been set up. Feel free to open a bug
and convince us otherwise!
