Abstract: An embodiment of the invention pertains to debugging program code associated with graphical objects, wherein the code responds to events of user interactions with the object. A menu is generated that includes user interaction events, and an associated program window is adapted to present the menu to a user when requested, wherein the user can select user interaction events from the menu. For each selected event, the method identifies a component of the program code that is responsive to that selected event. The method further includes setting a breakpoint in the program code in selected relationship with each identified program code component, wherein the subsequent occurrence of one of the selected user interaction events triggers a corresponding one of the breakpoints.

Abstract: An audio processing device includes: a display control unit, configured to control display of a plurality of audio gears, which are gears movable within a screen, each audio gear corresponding to predetermined audio data; and a playback control unit configured to control synchronized playback of a plurality of audio data; wherein, in the event that a plurality of the audio gears are directly or indirectly meshed, the display control unit rotates the plurality of audio gears, and the playback control unit performs synchronized playback of the plurality of audio data corresponding to the plurality of audio gears.
