Controls

The TCursor type defines a cursor ident (integer). The value -18 identifies an action denied cursor. It is used to indicate to the user that the cursor is hovering over an area which is not a valid target. It is represented by a black cross within a black circle.  

Use the Screen Cursor property to set the cursor type to one of the TCursor values.
