How do I create a SuperMover class?

How do I create a SuperMover class?

VFP has a _moverlists class included in its distribution which is based on two listboxes.
An alternative SuperMover class, a basic example of which follows, is based on two grids which in turn offers developers far more scope than is available in the _moverlists class.
FI, you can add checkboxes to the grids for further subselection, images to visually identify file types, comboboxes, multiple record selection, and so on.
The simple undocumented example selects fields from a table for inclusion in a search but the class lends itself to other forms of data selection.
As there is a limit of 254 fields in a VFP table, filters are applied to the two cursors required and it's unlikely there would be any serious performance implications using filters under these conditions.
If you were to deploy the class with serious numbers of records, then a SELECT-SQL statement to populate the cursors would be more appropriate.
What is not included for simplicity is a vertically aligned four command button set which is placed to the right of the second grid.
The button functions are:-
Move selected record top in second grid
Move selected record up in second grid
Move selected record down in second grid
Move selected record bottom in second grid
Other than that the class emulates most of the behaviour of the _moverlists class including double clicking and/or drag and drop to transfer from one grid to the other.
The selected records are identified as[color blue] SELECTEDLIST.selected = .T.[/color]
You need to replace the hard coded table reference in the init() event of the form either by passing a table name as a parameter to the form or by substituting your own tablename for the one supplied.
You also need to add the following form properties and values ensuring the path\filenames are correct
candropicon = "dragmove.cur"
nodropicon = "nodrop01.cur"
