Cursor interfaces: JOLAP's cursor interfaces define the functionality to manage multidimensional result sets returned by OLAP queries.
When the isolation level is cursor stability, the lock is released as the cursor moves from row to row.
As we discussed in Chapter 19, many programs currently rely on active wait-cursor hinting, turning the cursor into an hourglass.
My mouse cursor is over here on the top right, now, I touch the cat.

When the heel of your hand is down and you move the cursor from place to place, you use the fine motor skills of the muscles in your fingers.
One of the fundamental problems with direct manipulation in a 2D projection of a 3D scene is the problem of translating 2D motions of the cursor in the plane of the screen into a more meaningful movement in the virtual 3D space.

Active cursor hinting to indicate drag pliancy is a problematic solution. In an increasingly object-oriented world, more things can be dragged than not.
In many drawing and painting programs, when a user selects a tool from a palette the cursor changes so that it will perform specific functions upon clicking and dragging.
The only task of each drop candidate is to visually indicate that the hotspot of the captive cursor is over it, meaning that it will accept the drop—or at least comprehend it—if the user releases the mouse button. Such an indication is, by its nature, active visual hinting. Design Principle

Visual feedback for drag-and-drop As we’ve discussed, an interface should visually hint at its pliancy, either statically, in the way it is drawn, or actively, by animating as the cursor passes over it.
Use cursor hinting to indicate pliancy.
Cursor hinting communicates pliancy by changing the appearance of the cursor as it passes over an object or screen area.

But you receive a NullPointerException, because the current row no longer exists - it was modified, and the changes aren't visible in the current cursor.

The HTML division element will be positioned on the page with absolute coordinates, starting near the last saved cursor position, above any other layered elements.
As a user moves the cursor over connection candidates, cursor hinting should suggest that the two objects may be connected.
Generally speaking, controls should offer static or dynamic visual hinting, whereas pliant (manipulable) data more frequently should offer cursor hinting.
