prefposition(3G)

NAME
     prefposition - specifies the preferred location and size of a graphics
     window

C SPECIFICATION
     void prefposition(long x1, long x2, long y1, long y2)

PARAMETERS
     x1   expects the x coordinate position (in pixels) of the point at which
          one corner of the window is to be.

     x2   expects the x coordinate position (in pixels) of the point at which
          the opposite corner of the window is to be.

     y1   expects the y coordinate position (in pixels) of the point at which
          one corner of the window is to be.

     y2   expects the y coordinate position (in pixels) of the point at which
          the opposite corner of the window is to be.

DESCRIPTION
     prefposition specifies the preferred location and size of the next
     graphics window opened by winopen.  You specify the location in pixels
     (x1, x2, y1, y2).  Calling winopen activates the condtions specified by
     prefposition.

     After a window has been opened, its size and position can be changed by
     calling prefposition followed by winconstraints.  (Alternatively,
     winposition may be used in order to change the size and position of an
     already opened window.)

     Note that although prefposition causes the resulting window to be fixed
     in size (not resizable), it will still be possible to move the window.

EXAMPLES
     To open a window with a given size and position, but which will be
     resizable, use the following:

          prefposition
          winopen
          winconstraints

     The winconstraints following the winopen will remove the size contraint.
