- width Width Dimension 0 **1
- x Position Position 0

- **1 - If the Width or Height of the list widget is zero (0) then the value
- is set to the minimum size necessay to fit the entire list.
- If both Width and Height are zero then they are adjusted to fit the
- entire list that is created width the number of default columns
- specified in the defaultColumns resource.
- **2 - This is an array of strings the specify elements of the list.
- This resource must be specified.
- (What good is a list widget without a list?? :-)
- **3 - Longest is the length of the widest string in pixels.
- **4 - If either of these values are zero (0) then the list widget calculates
- the correct value.
- (This allows you to make startup faster if you already have
- this information calculated)
- NOTE: If the numberStrings value is zero the list must
- be NULL terminated.
- **5 - By setting the List.Columns resource you can force the application to
- have a given number of columns.
- **6 - This returns the name and index of the item selected in an
- XawListReturnStruct that is pointed to by the client_data
- in the CallbackProc.
