Interface Keypad

All Superinterfaces:

Function

public interface Keypad
extends Function

Keypad function provides support for keypad control. The keypad typically consists of one or more keys/buttons, which can be discerned. Different types of key presses like short and long press can typically also be detected. Each key pressed event is followed by a key released event. It's not possible to have two consecutive key pressed or key released events. There is only one eventable property and no operations.

Keypad can enumerate all supported keys in the key property metadata, PropertyMetadata.getEnumValues(String).
