/* Class Key_LayeredKeysBase contains an array of Key pointers, one pointer per layer.
|
|
Codes are a kind of Key, so the Key pointers can point to Codes or Keys.
|
|
|
|
When the key is pressed, active layerId is retreived and the Key object of that layer is called.
|
|
|
|
Design note:
|
|
Child classes (Key_LayeredKeys and Key_LayeredKeys1) have distinct static refLayerState
|
|
and different size ptrsKeys[].
|
|
That way Key_LayeredKeys instantiations don't need a LayerState argument,
|
|
which is significant for a sketch with 100 keys.
