Greetings.
Im trying to imagine (so I will program it) a normal procedure I can call from three or four fill-ins on window.
Tha idea is as follows. I have those widgets that call this procedure on the leave event to validate it's value. The call sholud send a ..widget-handle?... of the fill-in so the called procedure would validate: It's value diferent from others, that the value is a valid formated value, that it exists on a table (the value is PK to a table), and this has to be repeated three of for times on a data-entry window..
What would be the format of such procedure?
TIA

Something like this:
ON 'leave':U OF FRAME {&frame-name} ANYWHERE
PERSISTENT RUN leaveHandler IN THIS-PROCEDURE .
And then in the procedure, based on the SELF handle, no need to send a widget-handle.
PROCEDURE leaveHandler :
MESSAGE "self" SELF:NAME SELF:TYPE
VIEW-AS ALERT-BOX INFO BUTTONS OK.
END PROCEDURE.Personally I would prefer passing the handle of the widget to the handling procedure. That makes it explicitly clear what it is doing and makes it possible to call the procedure from other situations, where the 'SELF' would not work.
