The List_RegisterGroup() function defined in the syListObj form is used to register command lists that appear as groups in the action pane for a list. The command lists must be registered for them to be accessed by other list processing code.
List_RegisterGroup(list_object, command_list)
• list_object – The list object (composite) that specifies characteristics for the list. This value will have been passed into the procedure that is registering groups for the list.
• command_list – The command list resource that is being registered as a group for the list’s action pane.
A long integer containing the index of the registered command list.
This function is used during the list initialization procedure.
