MouseCursor cursor
override

The mouse cursor for mouse pointers that are hovering over the region.

When a mouse enters the region, its cursor will be changed to the cursor. When the mouse leaves the region, the cursor will be set by the region found at the new location.

Defaults to MouseCursor.defer, deferring the choice of cursor to the next region behind it in hit-test order.
