Embodiments relate to enabling wrap-around of a pannable surface to allow a user to perceive a logical break and to allow some user control over how/when a wrap-around occurs. When a user pans to an edge of a pannable surface ("near" edge), the panning, in some embodiments, is automatically halted or impeded. The user can over-pan the "near" edge, and if a condition is met, then the "distant" edge pans into view, thus effectuating a wrap-around. The condition may be, for example, a threshold distance, speed, inertia, etc. Some embodiments provide a hint or visual "peek" of the "distant" edge as the "near" edge is being over-panned. Some embodiments snap the "near" edge back if the over-pan is ended before the condition is met. The condition may be checked repeatedly during over-panning or it may be checked when the over-pan is terminated by the user. |
