The list methods

The topics below contain specification pages for list method subroutines. These method subroutines are written by you and their names are specified as arguments to UI Toolkit subroutines (such as L_CLASS or L_METHOD) or as qualifiers to the .LISTCLASS script command. Toolkit will then call them at the appropriate time.

Method subroutines are important in applications that will run in Windows environments, and they are also supported in UNIX and OpenVMS environments.

The following list methods are supported:

LARRIVE_METHOD / LLEAVE_METHOD - Perform list item arrive or leave processing

LDBLCLICK_METHOD - Perform list item double‑click processing

LLOAD_METHOD - Perform list item “load” processing
