event.type: A string representing the event type. event.mouseX: The mouse X coordinate relative to the view. event.mouseY: The mouse Y coordinate relative to the view. event.screenX: The absolute mouse X coordinate in the screen. event.screenY: The absolute mouse Y coordinate in the screen. event.altKey: A Boolean, true when the ALT key is pressed. event.ctrlKey: A Boolean, true when the CONTROL key is pressed. event.shiftKey: A Boolean, true when the SHIFT key is pressed.The key event passed to the
keyPress method is an object with
the following read-only properties:
event.type: A string representing the event type. event.keyCode: The key code.The mouse wheel event passed to the
mouseWheel method is an object with
