KeyPressDispatcher

class KeyPressDispatcher(name: String?) : HashMap<KeyCharAndCode, () -> Unit>

A manager for a keyTyped InputListener, based on HashMap. Uses KeyCharAndCode as keys to express bindings for both Ascii and function keys.

install and uninstall handle adding the listener to a Stage. Use indexed assignments to react to specific keys, e.g.:

    keyPressDispatcher[Input.Keys.F1] = { showHelp() }
    keyPressDispatcher['+'] = { zoomIn() }

Optionally use setCheckpoint and revertToCheckPoint to remember and restore one state.

Parameters

name

Optional name of the container screen or popup for debugging
