Class: UIComponent

UIComponent

Base class for all the UI component classes, a UI component is a HTMLElement positioned with geographic coordinate.
It is abstract and not intended to be instantiated.

(abstract) new ui.UIComponent(options) [source]

Some instance methods subclasses needs to implement:

1. Optional, returns the Dom element's position offset
function getOffset : Point

2. Method to create UI's Dom element
function buildOn : HTMLElement

3 Optional, to provide an event map to register event listeners.
function getEvents : void
4 Optional, a callback when dom is removed.
function onDomRemove : void
5 Optional, a callback when UI Component is removed.
function onRemove : void
