ANTICIPATING DROP ACCEPTANCE INDICATION

Permitting or prohibiting a drop is executed at the beginning of the drag-and-drop action initiated by the user, by mouse-clicking on the object to be dragged, for example. Thus, the drag-and-drop action is shown as a visual drop permission or prohibition in the relevant drop areas, such as a visual queue, for example, check mark, etc. In the preferred embodiment, and upon initiation of the action, the surface components display which areas, parts, elements or substructures can or cannot accept a given object or data element before a mouse pointer, arrow or cursor reaches or moves over the relevant areas, parts, elements or substructures.
