Enum editor
***********

This dialog lets you define the name and list of options for an enum
column type.  It has a list of the enum's options and the same set of
buttons as most of the other editor dialogs:

**Add**
   Add a new option; a dialog will appear for you to enter the option
   text into.

**Edit**
   Change the text of an existing enum option.  All existing uses of
   this option will be updated to the new text.

**Delete**
   Delete the currently selected option.  A dialog will ask you to
   pick the value to use wherever this option was being used.

**Up**
   Move the currently selected option up one position in the list (and
   hence in the selection droplist as well).

**Down**
   Move the currently selected option down one position in the list
   (and hence in the selection droplist as well).

Just below the enum name are more buttons which allow you to change
the list of options:

**Sort**
   Sort the options in alphabetical order.  Click the button again to
   reverse the sorting order.

**Import**
   Add options from a text file; this file should have each option on
   a separate line.  Options in the file which are already in the enum
   will not be duplicated.

**Export**
   Create a text file listing the current enum options, one on each
   line.

Click "OK"/"Done" to accept any changes that were made or cancel out
of the dialog to leave the options unchanged (or cancel adding a new
enum).
