[SQLObject] Finding StringCol lengths

[<jws...@ra...>]

To create a basic gui form interface to my objects, I need to be able to get
some sort of hints regarding the name, number and size of fields the object
has. I can get a list of columns with _SO_Columns or _SO_columnDict, but
that does not contain the field lengths I specified in my classes. My
strategy was to create a public method that combined the private methods
above and the length information from wherever I could find it. However, it
seems that the length, if specified, is only used for validation and table
creation. Where can I extract this information?

I believe you can get it through _SO_columnDict[colName].length, though 
only for StringCols, of course.  If you look in Col.SOString you'll see 
it being assigned.
