5.12 Event Handlers
BusCommandHandler
When enabled, this event handler is activated when new data arrives on a field bus option card. SetImage() must
be called before BusCommandHandler() will be activated again. A new activation of the handler can occur when
new data is present on the bus.
Method Signature:
BusCommandHandler()
xKeyReleased
This class of event handlers is activated when a key is released. The "x" is replaced with the name of the key. Key
names are the same as for the xKeyPressed handlers. Note that the xKeyReleased handlers are subject to the
same timing considerations as all other user handlers. The events are queued in the order they are detected. Any
handler that involves lengthy operations may delay the start of other handlers.
Method Signature:
handler xKeyReleased;
