The MENU sub-dialog
The MENU sub-dialog implements a list of choices for the user by using
action handlers.
MENU implements a list of action handlers
The following code example shows a MENU sub-dialog implementing a
couple of action handlers with an ON ACTION clause or with a
COMMAND clause (action views of COMMAND can
get the focus):
DIALOG ()
MENU
ON ACTION customer_view
...
ON ACTION order_view
...
END MENU
END DIALOG
Control blocks in MENU
Simple
record input declared with the INPUT sub-dialog can
raise the following triggers:
In the singular MENU instruction, BEFORE MENU and AFTER
MENU blocks are typically used as initialization and finalization
blocks. In an MENU sub-dialog of a DIALOG block,
BEFORE MENU and AFTER MENU blocks will be
executed each time the focus goes to (BEFORE) or leaves
(AFTER) the action views (buttons) controlled by this
sub-dialog.
