Enum Class Cursor

java.lang.Object

java.lang.Enum<Cursor>

limn.backend.Cursor

All Implemented Interfaces:

Serializable, Comparable<Cursor>, Constable

public enum Cursor
extends Enum<Cursor>

A standard mouse-cursor shape a widget can request while hovered: the OS's native pointer, so it looks and feels exactly like every other application.

Widgets declare one via Widget.setCursor(limn.backend.Cursor); the scene resolves the hovered widget's cursor (walking up ancestors so a container can set a cursor for its whole subtree) and pushes it to the window through NativeWindow.setCursor(limn.backend.Cursor). DEFAULT is the plain arrow, the fallback when nothing under the pointer requests otherwise.

A shape unsupported by the platform falls back to DEFAULT.
