Abstract: A data processing system, software program, and method of operation realistically displays a users model of a device as an object, while providing additional functions which cannot exist in the devices real-world counterparts. The data processing system and software program allow a view or a realistically-rendered object and a function associated with that object to be selectively modified in response to a user input. During operation, a cursor displayed by a display device (138) is used to access a view changing mechanism displayed on the realistically-rendered object. By selectively accessing the view changing mechanism, a user is able to change a view of the realistically-rendered object from a base function view to a full function view.

Abstract: A data processing system, software program, and method scale the contents of a window or similar display area in unison and in proportion. During operation, all of the contained control, text, and images included in the window are scaled proportionately so that a user is still able to use the displayed object and the displayed object retains its characteristic image. Composite images of realistically-rendered objects are resized and moved in a manner which is dependent upon a common non-changing representation of a container and a contained object displayed on a display device. When the common non-changing representation is modified by resizing, a scaling operation is performed on the composite image as a whole. However, when the representation of a contained object is modified and the common non-changing representation is no longer displayed, a region of a contained object is "clipped out" from the container before the image is displayed.

Abstract: A data processing system and method of operation thereof detect when a situation occurs in which a window displayed on a display device should be brought to a user's attention. That window is then surfaced at the top of a window system z-order of the data processing system without modifying a current activation state of the window. Thus, while the window is guaranteed to be visible or unobscured by any other windows, the current activation state is not changed and any user input is still in control of the user.
