drop-cursor

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 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 instance which is returned by the expression (find-cursor :default-drop-cursor) (see find-cursor). This cursor shows a thick arrow pointing downward, indicating that a drop is allowed onto this dialog-item.

drag-cursor and no-drop-cursor return mouse cursors to use at other times during a drag.
