4D v11 SQL now allows referencing a Hierarchical List object via its object name. Because of this, the following commands in the Object Properties theme may be used with Hierarchical List objects. Using the object name will only affect the Hierarchical List object and not the Hierarchical List.

FONT
FONT SIZE
FONT STYLE
SET SCROLLBAR VISIBLE
SCROLL LINES

NOTE: Omitting the "*"parameter and passing only the variable name of the Hierarchical List (which is the reference ID of the list) will result in the commands modifying all Hierarchical List objects referencing the same list.
