Selection-list Events
An enabled selection list accepts many events. The selection list:
- Accepts input focus by way of the navigation key functions (such as TAB) or the mouse
- Responds to the universal key functions (such as GO or HELP)
- Moves input focus among the list items with the cursor keys or the mouse
- Responds to alphanumeric keys by moving the cursor to the first list item that begins with that letter.
- Accepts input from SPACEBAR or RETURN.
- Responds to ENTRY, LEAVE, VALUE-CHANGED, and DEFAULT-ACTION triggers
DEFAULT-ACTION Event
A default action is an interaction with a widget that signals the widget to perform a task associated with the widget. For example, issuing a default action with a selection list might make the display update with new information about the selection. The default action for a selection list is to press ENTER or RETURN after selecting a list item or to double-click the desired list item. When a user issues the default action, the DEFAULT-ACTION event occurs, making this event the one to use for associating tasks with widgets that support a default action.
