摘要

Disclosed is an electronic device such as a PDA, smartphone or laptop computer, in which the display is divided into a plurality of display areas. The visual representation of the boundary between the display areas changes as a user moves a selected GUI object, eg a screen icon, in a first area towards or into a second screen areas. The boundary change may change when the movement of the GUI object satisfies set threshold conditions. The movement may invoke an operation linked to the moved GUI object. The GUI object may represent an unlock function. Also disclosed are methods of controlling the state of a function and controlling the operation of an electronic device by moving an GUI object between screen areas and by changing the appearance of the boundary between the display areas.
