If the query is already prepared then you can do something like...
Query.FieldByName('CUST_NAME').DisplayWidth := 420;

Whether the query is prepared or not you can...
Query.FieldsDisplayWidth.LinkValues['CUST_NAME'] := 420;

You can find out more by looking at the online help for

The only method I can think of would be to derive your own version of
TIB_Grid and override the UpdateColumnAttributes procedure to do your
own thing.

Jason has been concentrating on the code, and most of the rest of us
do the same. If you wish to volunteer to help with writing some
documentation I am sure Jason would welcome it. It can easily be
added to the .INT (interface) parts of the units, ready to be compiled
into the help file. If you are interested let me know and I can
provide more details about how it is done - or you can look at what is
already there for example.

(Finding time for documentation would simply not be in keeping with
the spirit of programming ;-)
