NAME    [Toc]    [Back]

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

C SPECIFICATION    [Toc]    [Back]

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

PARAMETERS    [Toc]    [Back]

     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    [Toc]    [Back]

     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    [Toc]    [Back]

     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.
