An apparatus, program product, and method define a portion of the window
content information for a window as a prioritized display element that is
displayed in a non-occluded region of a computer display in response to a
determination that at least a portion of such a display element is
occluded by another display element on the computer display. Also, an
apparatus, program product and method manipulate multiple windows
displayed on a computer display by moving a window in response to user
input to move another window when it is determined that the movement of
the other window would occlude at least a portion of the window. In
addition, an apparatus, program product and method facilitate the
selection of a subset from a set of information displayed on a computer by
displaying a display representation of a set of information on a computer
display, with a portion of the display representation occluded such that
the display representation is partitioned into occluded and non-occluded
regions. Then, in response to user input, a subset from the set of
information that is represented by one of the occluded and non-occluded
regions of the display representation is selected.
