I have an ArrayCtrl with 7 elements, like that of the output of
"ls":

index, name, user, group, size, date, perm

The first is an Index, and is not viewed. Next I thought it would be nice if the user could chose which fields are used. To avoid having to store which column is what in my code, I went down the route where I always add 7 elements, but turned them off or on depending on user selected options.

However, I could see no apparent way to just enable or disable a column. (is that the case? HeaderObject().HideTab(int) did nothing for me).

So, instead I went down the road where I either AddColumn(), or AddIndex() based on whether or not it is enabled.

This appears to work ok, except when I call .Reset() and re-add the Columns/Indeces. I lose the User set Width.

It would appear that I have a ColumnsWidths(char *) function to set them, but I am unsure how to get what they are. HeaderObject().GetTabWidth() seems to give me the default/initial width, not the current width.

On the other hand, Serialize() appears to work fine, but it works with streams. But perhaps that is the proper path? (Do I really need to open a stream just to save the widths?)
