An object-oriented user interface utilizes object-oriented controls that operate together as a single, atomic group to change data values and are affected as a group by conventional editing "undo" and "redo" actions. In accordance with one embodiment, each control in the group generates a command which modifies a stored control value when the control is manipulated by a user. In response to user activation, a group acceptance control generates a command which causes the data values to be changed to the stored control values. In accordance with another embodiment, each control in the group generates a command which modifies the group acceptance control command. When the group acceptance control command is finally activated, the modified command causes the data values to be changed. The entire control group can also be undone and redone in a single atomic operation which is implemented by placing a mark on an undo stack when an interface session involving a control group is started. When the session ends, all of the commands executed since the mark was placed on the undo stack are collected together into a single command group which can be undone or redone as a unit.
A system for processing, in an atomic manner, commands generated by user interface control objects in order to modify data values corresponding to the user interface control objects in response to the activation of a group acceptance control object having a group acceptance graphic displayed on a display screen, the system comprising:
