DMXChangeDesktopAttributes(Library Functions ManuDMXChangeDesktopAttributes(3)

NAME
       DMXChangeDesktopAttributes - change global bounding box

SYNOPSIS
       #include	<X11/extensions/dmxext.h>

       int DMXChangeDesktopAttributes(Display *dpy,
				      unsigned int mask,
				      DMXDesktopAttributes *attr);

DESCRIPTION
       DMXChangeDesktopAttributes()  resizes  the  bounding  box  of the whole
       screen when using the Xinerama extension.  Otherwise, it	has no	effect
       on  the screen layout.  An attribute mask is placed in mask and the at-
       tributes	to change are placed in	attr.

       The values that are used	to compute mask	are as follows:

       DMXDesktopWidth
       DMXDesktopHeight
       DMXDesktopShiftX
       DMXDesktopShiftY

       The DMXDesktopAttributes	structure is:

       typedef struct {
	   unsigned int	width;
	   unsigned int	height;
	   int		shiftX;
	   int		shiftY;
       } DMXDesktopAttributes;

       width  and  height specify the new width	and height  for	 the  bounding
       box.   shiftX   and   shiftY  specify where the Xinerama	origin will be
       placed with respect to the origin of the	new bounding box.  This	allows
       the  left  and  upper  edges  of	the bounding box to be changed without
       changing	the visual position of the windows on the desktop.   If	 width
       or   height  is	not  specified,	 the  current values will be used.  If
       shiftX  or  shiftY is not specified, 0 will be used.

       All coordinates are in the global DMX coordinate	system.	  If  Xinerama
       is not active, an error will be generated.

RETURN VALUE
       DMXChangeDesktopAttributes()  will  return 0 on success,	DmxBadXinerama
       if Xinerama is not active, DmxBadValue if the size of the bounding  box
       is too large, and DmxBadReply if	there was a protocol error.

       DMXChangeDesktopAttributes()  can generate BadLength (if	the request is
       malformed, which	should never happen when  using	 this  library	inter-
       face), and BadValue (if any values are out of range).
