See-Through Window

      A disclosed mechanism is for displaying information hidden
behind an overlapping window in window applications.

      In current window systems, to display information that is
hidden behind an overlapping window, one or more of the following
operation is needed:

1.  Raise the hidden window to the top of the desktop screen by
    changing the window focus.

2.  Move windows in order to display the information contained in the
    hidden window.

3.  Resize windows in order to display the information.

4.  Close unnecessary windows in order to display the information.

      The disclosed mechanism allows the user to get information
without the above operations.  Assume that window A overlaps and
hides an area of window B. If we put a see-through window on top of
window A, it makes the area of window A behind it transparent, thus
allowing the information contained in window B, which is hidden by
window A, to be displayed.  The user can move and resize the
see-through window in the same way as ordinary windows; thus, the
user can control the size and position of an area to be made
transparent.

To implement this mechanism, the following three functions are
needed:

1.  Determination of the window to be made transparent.  This
    function includes management of the window overlapping level.
    For example, a window is assigned a priority number.  The
    priority number of the overlapping window is higher than that the
