The string representing the cursor style.
A disposable which will clear the override when disposed.
The most recent call to overrideCursor takes precedence.
Disposing an old override has no effect on the current override.
This utility function is used by the Drag class to override the
mouse cursor during a drag-drop operation, but it can also be used
by other classes to fix the cursor icon during normal mouse drags.
import { Drag } from '@lumino/dragdrop';
// Force the cursor to be 'wait' for the entire document.
let override = Drag.overrideCursor('wait');
// Clear the override by disposing the return value.
override.dispose();
Override the cursor icon for the entire document.
