Graphics

TThe Graphics section provides details on the graphics and keyboard interface for the program together with comments on the limits imposed by available screen resolution. The program displays the cube and associated elements on the scroll pane area of the Unravel frame. The scroll pane is the frame's main display area and is used to display the canvas (component, comprising cube and other graphics items, which is added to the scroll pane).

An option is provided that allows part of the cube to be hidden (scrolled out of view) for cubes of large size. The Cube display options section provides details on this option. When the scroll option is not enabled the complete canvas fits in the viewing area of the scroll pane and remains that way unless the user re-sizes the frame by enabling the scroll option. That option can always be changed via the Unravel Options dialog presented in the start-up sequence for Auto mode, but it requires the user to select Menu mode to access the Unravel Options dialog thereafter during the session. Menu mode can be selected on exit from the Command Sequence Input dialog when Auto mode is in use.

User interface (UI) with the program is achieved mainly via dialogs but the frame's menu and toolbar can also be accessed in Menu mode.
