Mouse event fired when mouse button pressed, released, clocked, moved, or dragged on a node/ scene. Primary, secondary, middle, none indicates left, right, middle, and none mouse buttons: getbutton() returns which button is pressed. Key event fired when key is pressed, released, or typed on a node/ scene. Every key event has a key code: getcode() returns key code. Key code is an enum type: gettext() returns string describing key code, getcharacter() returns empty string requestfocus() node that calls this can received keyevent, after clicking a button, the node is no longer focused. Adding listeners allows you to process value changes in an observable object. Instance of observable == observable object: contains addlistener(invalidationlistener listener) for adding a listener, listener class must implement invalidationlistener interface. Overrides invalidated(observable o) method for handling value changes. Once value is changes listener notified by invoking invalidated(observable o) Binding properties are instances of observable method. Javafx provides animation class with functionality for all animations.
