[gtkada] Clist Tab problem

[Kevin K]

Last year we upgraded a GtkAda program from 1.2.12 to 2.10 along with an
upgrade to support RHEL5.
One change we just noticed recently is that we can't tab through the titles
in a multi column Clist anymore.  The focus only stops on the first active
column title.  With 1.2.12, you could then arrow over to the other titles,
and use the keyboard to select it.  We can still use the mouse to click,
though.

I'm guessing that it is a problem with the underlying gtk+, and not the Ada
implementation, but I thought I would check if anyone else has seen this?  I
checked with the version ported awhile back to Windows, and it does it there
too, but no one had ever noticed in this world of mice and touchpads :)  So
it doesn't seem to be a Linux problem.

I also see that CList is deprecated, but in the short term there isn't time
to convert it to a Tree_View.

Thanks,
Kevin
