Otherwise, it has no effect on the screen layout. An attribute mask is placed in .I mask and the attributes to change are placed in .IR attr . .PP The values that are used to compute .I mask are as follows: .sp .nf DMXDesktopWidth DMXDesktopHeight DMXDesktopShiftX DMXDesktopShiftY .fi .PP The .B DMXDesktopAttributes structure is: .sp .nf typedef struct { unsigned int width; unsigned int height; int shiftX; int shiftY; } DMXDesktopAttributes; .fi .PP .I width " and " height specify the new width and height for the bounding box. .I 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 .I width " or " height is not specified, the current values will be used. If .I shiftX " or " shiftY is not specified, 0 will be used. .PP All coordinants are in the global DMX coordinant system. If Xinerama is not active, an error will be generated. .SH "RETURN VALUE" .B DMXChangeDesktopAttributes() will return 0 on success, .B DmxBadXinerama if Xinerama is not active, .B DmxBadValue if the size of the bounding box is too large, and .B DmxBadReply if there was a protocol error. .PP .B DMXChangeDesktopAttributes() can generate .B BadLength (if the request is malformed, which should never happen when using this library interface), and .B BadValue (if any values are out of range). .SH "SEE ALSO" .BR DMXGetDesktopAttributes "(__libmansuffix__), " DMX "(__libmansuffix__), " Xdmx (1)
