Monitoring of Flex keyboard events

Flex event monitoring mechanism is very perfect, the following is a brief talk about Flex keyboard event monitoring.

First of all, to understand a concept, the object of the Flex keyboard event, through practice, I know that it is actually a container, and the menu is divided into ordinary containers such as stage and HBox.

Second, to understand that Flex keyboard events are also events, event monitoring is nothing more than listening with event handlers (such as click), here using keyDown; or addEventLisner

In the following example, I use both, application uses addEventLisner, and the custom control com uses keydown; when the event is triggered, and the former is executed before the latter.
