Data processor controlled display system with drag and drop movement of displayed items from source to destination screen positions and interactive modification of dragged items during the movement

摘要

In a basic display screen interface implementation for enabling an interactive user to move a data component from a source to a destination in said system via means for representing said data component by an item, e.g. icon on said display screen combined with means for interactively dragging said item from an initial location on said screen representative of said source to a final location representative of said destination, there is provided a further expedient for interactively modifying the data component before said dragged item reaches said final location. The implement for dragging said icon includes an implement for dragging the icon into contact with another icon to thereby activate the means for interactively modifying the data component represented by said dragged icon.
