Arguments: dialog-item
Returns the mouse cursor image to be used while doing a drag-and-drop whenever the mouse cursor is over dialog-item and dropping onto that dialog-item is not allowed. (droppable-p methods determine where dropping is allowed.)
An application typically would not need to call this generic function,
but may define methods on it to customize the mouse cursors that are
used by drag-and-drop. The returned value
should be either an instance of the cursor class or a mouse cursor
handle.
The default method returns the mouse cursor handle which is the value
of the variable no-drop-cursor. This cursor shows
a red circle with a diagonal line through it, indicating that it is
not possible to drop the dragged value onto this
dialog-item.
drag-cursor and drop-cursor return mouse cursors to use at other times during a drag.
