An approach is described for implementing a GUI that an account for illegal operations by the user. Visual ghosting is implemented that includes separation support. If an object is manipulated into an impermissible/unacceptable configuration, ghosting separation is performed to display multiple ghost images, where a first ghost image shows a legal configuration of the object and a second ghost image shows the current configuration of the object. The second ghost continues to track the user's manipulation of the object until a legal configuration is achieved. The improved approach provides a visual representation that corresponds to the expected end result, but is also be useful to track the user's actions if there is a violation. |
