ABSTRACT:
A computer system and method manipulate a window or similar graphical user interface component through collision of a pointer controlled by a user with the boundary of the window. When it is determined that user manipulation of a pointer along a first vector intersects a boundary segment of a window displayed on a computer display, the boundary segment is moved along a second vector. The second vector may be identical to the first vector, or may represent only a component thereof. Moreover, either the entire boundary of the window may be moved such that the window itself is effectively moved, or one or more segments of the boundary may be maintained at a fixed location such that the window is effectively resized. In addition, this feature may be selectively enabled and/or disabled by a user. Moreover, a pointer may be defined to have a single position from which the first vector extends, or in the alternative, a pointer may also have a proximity range having a perimeter that defines the extents of the pointer, and that may or may not be coextensive with the visible shape of the pointer.
