I don't claim to be a technical writer. The doc seems clear to me, but it
may not be to others. It is relatively simple:
* There are two types of sorts. 1) The sort is implemented in your Rexx
code. 2) The sort is implemented in the internal ooDialog code.
* To use the internally implemented sort, the method name argument must be
InternalListViewSort
* To use the sort implemented in your Rexx code, the method name argument
must be anything that is not InternalListViewSort
* For either of the two types of sorts, every list-view item must have an
object assigned as its data item.
* For the internally implemented sort, the data item must be a LvFullRow
item.
* For the sort implemented in your Rexx code, the data item can be any
object you want.
