SWAPPING USER- INTERFACE OBJECTS BY DRAG-AND-DROP FINGER GESTURES ON A TOUCH SCREEN DISPLAY

摘要

A portable multifunction device (100) displays a first user interface object (4350) and a second user interface object (4310) on a touch screen display (112). Upon detecting a finger-down event (4346-2) at the first user interface object (4350) and one or more finger-dragging events (4365) on the touch screen display (112), the device (100) moves the first user interface object (4350) on the touch screen display (112) along a path determined by the finger-dragging events (4365) until the. first user interface object (4350) at least in part overlaps the second user interface object (4310). Upon detecting a finger-up event (4346-3) at the second user interface object (4310), the device (100) visually replaces the second user interface object (4310) with the first user interface object (4350).
