prefpo(3G)

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

FORTRAN 77 SPECIFICATION
     subroutine prefpo(x1, x2, y1, y2)
     integer*4 x1, x2, y1, 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
     prefpo specifies the preferred location and size of the next graphics
     window opened by winope.  You specify the location in pixels (x1, x2, y1,
     y2).  Calling winope activates the condtions specified by prefpo.

     After a window has been opened, its size and position can be changed by
     calling prefpo followed by wincon.  (Alternatively, winpos 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:

          prefpo
          winope
          wincon

     The wincon following the winope will remove the size contraint.
