@FunctionalInterface public interface KeyEventPostProcessor
Note that the KeyboardFocusManager itself implements KeyEventPostProcessor. By default, the current KeyboardFocusManager will be the final KeyEventPostProcessor in the chain. The current KeyboardFocusManager cannot be completely deregistered as a KeyEventPostProcessor. However, if a KeyEventPostProcessor reports that no further post-processing of the KeyEvent should take place, the AWT will consider the event fully handled and will take no additional action with regard to the event. (While it is possible for client code to register the current KeyboardFocusManager as a KeyEventPostProcessor one or more times, this is usually unnecessary and not recommended.)
|Modifier and Type||Method and Description|
This method is called by the current KeyboardFocusManager, requesting that this KeyEventPostProcessor perform any necessary post-processing which should be part of the KeyEvent's final resolution.
boolean postProcessKeyEvent(KeyEvent e)
redispatchEventto prevent the AWT from recursively requesting that this KeyEventPostProcessor perform post-processing of the event again.
If an implementation of this method returns
false, then the
KeyEvent is passed to the next KeyEventPostProcessor in the chain,
ending with the current KeyboardFocusManager. If an implementation
true, the KeyEvent is assumed to have been fully
handled (although this need not be the case), and the AWT will take no
further action with regard to the KeyEvent. If an implementation
consumes the KeyEvent but returns
false, the consumed
event will still be passed to the next KeyEventPostProcessor in the
chain. It is important for developers to check whether the KeyEvent has
been consumed before performing any post-processing of the KeyEvent. By
default, the current KeyboardFocusManager will perform no post-
processing in response to a consumed KeyEvent.
