Syntax
LIST-WIDGETS ( event-name[ , platform] )
event-name
A character-string expression that evaluates to an event name.
platform
A character-string value that specifies a display type. Valid values are GUI and TTY. Some events are valid only on certain platforms. If you omit the platform parameter, the AVM uses the platform for the current session.
